ALERT NEWSLETTER – June 2019

Hi Everyone,

I hope this finds you well.

The results of our May ALERT elections are in and I wish to welcome our new leaders as they lead ALERT into the future.

President: Johnnie Knobloch, KJ4OPX
Johnnie is active in the amateur radio emergency communication serving as Jefferson County Emergency Coordinator for ARES, Latter Day Saints Emergency Coordinator, Vice-President of the Central Alabama Chapter of the National Weather Association and very active with the Healthcare Amateur Radio Club.

Vice President: Peter Shaw, KX4LB
Peter is active in amateur radio, disaster recovery and preparation, part of the health care community, and active with call-outs and weather nets.

Treasurer & Membership: Bill Rodgers, K4FSO
Bill sets up amateur radio demonstrations in schools, allowing middle school students talk to astronauts on the International Space Station, among other projects.

Secretary: Justin Glass, N0ZO
Justin is a Volunteer Examiner for Laurel VEC, administering free amateur radio license exams, with Central AL ARC.

NWS Liaison: Russell Thomas, KV4S
Russell, one of our longest term members, has brought us much greater digital amateur radio integration, bridging modes such as DMR, Echolink, AllStar, D-Star (XRF), in an effort to make it easier for areas not reachable via VHF/UHF to connect with ALERT and the NWS.

A special thanks should be given to our outgoing President, Casey Benefield, NZ20. He and Russell have brought ALERT into the digital age, helping keep ALERT relevant in the rapidly evolving Amateur Radio Emergency Communication world. One of the major accomplishments of Casey’s terms of office is opening a dialogue our counterparts at NWS Mobile – the Rural Radio Preparedness Association. This opens tremendous possibilities for Amateur Radio communications and the NWS mission of saving lives.

ALERT is alive and well!

Our Newsletter will continue as it has, and I invite your ideas and articles!

In this month’s newsletter will present our annual review tropical weather as we enter the hurricane season.

I hope you enjoy!

2019 Atlantic Hurricane Season Begins

The Atlantic Hurricane Season officially begins June 1. NOAA’s Climate Prediction Center is predicting a near-normal Atlantic hurricane season this year. NOAA predicts a likely range of 9 to 15 named storms, of which 4 to 8 could become hurricanes, including 2 to 4 major hurricanes. NOAA provides these ranges with a 70% confidence. An average hurricane season produces 12 named storms, of which 6 become hurricanes, including 3 major hurricanes.

As mentioned last month, Colorado State University predicts 13 named storms, 5 of which could become hurricanes this year and 3 storms may reach Category 3 or stronger.

In the grand scheme of things it doesn’t really how many storms actually do form, what matters is where they end up arriving. A year with 28 storms that never reach land isn’t overly significant, where a year with only one named storm and it being a repeat of Katrina, Camille or Andrew is.

With the 2019 North Atlantic Hurricane Season beginning it is a good time to review our preparedness plans.

Hurricane Impact & Hurricane Response

Alabama is impacted by hurricanes in three ways:

1. Direct Impact – Where the core of the storm or the rain / wind field actually strikes or passes through a portion of Alabama. Examples being Hurricane’s Fredrick, Opal, Ivan and Katrina.

2. Indirect Impact – where the core is not over Alabama, but the feeder bands are passing through and causing havoc. Rita’s feeder bands being a good example, which dropped 21
tornadoes over west Alabama in a 4-hour period.

3. Distant Impact – A storm is not even near Alabama, but affecting our weather. Such as with Olivia, a Pacific Hurricane which was off Western Mexico. Her moisture was captured by the jet stream, crossed the Sonora desert, the Arklatex region & dumped monsoon type rains on Alabama & Mississippi, causing flooding.

ALERT typically will activate during scenarios 1 & 2. ALERT’s coverage would concentrate on monitoring D-Star directly and using a liaison station to monitor HF offsite on 3.965 MHz or the backup 40-meter frequency of 7.243 MHz.

Then as the storm moves northward into the BMX County Warning Area the focus would then shift to the individual county Skywarn Nets, as we would do during a “normal” callout.

HF Gulf Coast Nets to monitor are:

Primary State ARES Frequencies & Nets for Gulf of Mexico & regular meeting times.

3.965 MHz Alabama Emergency Net Mike 4:00 PM Sunday*
3.940 MHz Florida Amateur Single Sideband Net 6:00 PM
3.975 MHz Georgia Single Sideband Net 7:30 PM
3.910 MHz Louisiana Traffic Net 6:30 PM
3.862 MHz Mississippi Section Phone Net 6:00 PM
3.873 MHz Texas Traffic Net 6:30 PM

* Note that this is also the frequency of the Alabama Traffic Net Mike, meeting daily at 6:30PM Central & Sunday’s at 8:00 AM Central and the Alabama Day Net, which meets daily at 10:00 AM Central Time.

Wide Coverage Nets

14.235 MHz Hurricane Watch Net As Needed
3.935 MHz Central Gulf Coast Hurricane Net 1:00 UTC

The Hurricane Watch Net is only activated when a storm is within 300 miles of a populated land mass. Normally you shouldn’t check into this net, but you only listen. Only check in if you have a legitimate need to do so. A legitimate need being emergency or priority traffic or if the NCS specifically calls for a station in Central Alabama, only then should you pick the microphone up. Occasionally, if there is a lull in activity, they may actually give a call for general check-ins. But, don’t be surprised if they don’t. Helping stations in the affected area is their primary concern.

Once upon a time a, which if I remember correctly was in 1988 when Gilbert, was rearranging Jamaica, the NCS asked “do we have any stations in the affected area, the affected area only?” Some fellow from Zero-land, piped in and very slowly drawled out “This is Kay Zero Que Arr Emmm, Homer over in Tulsa Oklahoma, just wanting to tell you fellers what a fine job, a fine job you fellers are doing. And, if I can be of any help, any help at all just let me know. This is Homer, K0QRM, over in Tulsa Oklahoma on frequency and standing by on the side.”

Fifteen distress calls probably could have been received and handled in the time it took Homer to ooze over “on the side”.

Learn from a bad example. Don’t do this.

Hurricane Tracking Gleams And Glints From Mark’s Crystal Ball

I’ve always enjoyed trying to second-guess the National Hurricane Center. It’s fun! Many times our forecasts agree, they have outguessed me an honorable number of times & every now and then, when Divine Providence intervenes, I have beaten them.

The following are some random hints and items I have stored in my dusty brain, which every now and then come into play as I gaze into my tropical crystal ball:

The maximum number of tropical systems that the Atlantic Basin (which includes the Gulf and Caribbean) can simultaneously contain and support is four storms.

If major tropical systems get too close to one another they don’t merge as thunderstorms often do. The upper level winds associated with each storm counteract or buffets each other preventing this from occurring.

If you have a large storm and a smaller storm enters the influence or wind field of the larger storm, the smaller storm will tend to rotate counterclockwise around the primary storm in a process called the Fujiwhara Effect.

If the smaller storm is very weak, say a tropical storm versus a Category 4 storm, it is possible that the smaller storms circulation can be totally disrupted by the larger storm and then it can be absorbed into the larger storms circulation. See http://www.youtube.com/watch?v=fNjUSsqJgek&feature=relmfu as Typhoon Ma-On gobbles up Tropical Storm Tokage in 2011.

Tropical systems, for all of their tremendous energy, are totally without an engine or steering mechanism, but are at the mercy of the whims of the upper level winds. A tropical system can spin all it wants to, but unless the storms thunderstorm columns reach high enough to snag the upper level winds, and then act as a sail, the storm is going nowhere fast. If the upper level winds die down, the storm can drift aimlessly for days.

If the storm sits still long enough, it will begin to dissipate due to it stirring up the deeper cooler waters beneath it and it cooling the sea surface temperature below the 80 degree critical threshold needed to sustain a tropical storm. This is “upwelling”. The one exception to this rule is if it is sitting over the Gulf Stream, as the incoming current will continually replenish the warm water beneath the storm.

A well-formed storm will have a perfectly circular Central Dense Overcast or CDO, an area of thunderstorms surrounding the eye wall, with “feeder bands” of thunderstorms spiraling inward counterclockwise, parallel to the storm’s inbound horizontal winds, and “feeding” energy from the warm tropical ocean into the storm.

The winds being drawn into the eye, once arriving, can only go in one direction – up – and in a well formed storm the system will be capped by high pressure, which helps evacuate these winds as they reach the stratosphere. This forms a false cirrus shield of clouds rotating in a clockwise fashion, as the winds are vented outward. If the storm has a tear drop shape or a long plume of clouds extending from the storm, this indicates heavy shearing, which will limit its growth, or shred the circulation. The storm will be veered by the shearing and try to deflect towards the direction of the plume.

A poorly organized storm can have a completely exposed center, with the cloud shield nowhere near the center. Until it starts “stacking up” it will remain a weak storm.

Intense, Category 3 or greater hurricanes will go through a process called an “eyewall replacement cycle”. In this case the eyewall contracts so small that some of the outer rain bands may strengthen and form an outer eyewall, causing the storm to weaken by robbing energy from the inner eyewall and will eventually choke it out completely and replace it, causing the storm to re-intensify.

This is a common occurrence. Less common is when you have a triple eyewall, as was the case with Typhoon June and Hurricane Juliette.

The fastest intensification from a Tropical Storm to a Category 5 Hurricane occurred with Hurricane Wilma in 2006, which in 16 hours went from 70 mph to 155 mph and then vacationed in the Yucatan.

The fastest intensification from a Tropical Depression to a Category 5 Hurricane occurred with Hurricane Felix, which took just 51 hours to bloom and then blessed Nicaragua with its presence in 2007.

Tropical systems cannot penetrate frontal boundaries. If a tropical system is threatening the coast, and you see that a front will be approaching the coast from the West, don’t worry about the coast, as it will either stall the storm, deflect it to the Northeast or as in the case of 2009’s Tropical Storm Danny, it can absorb a weak storm.

When looking at hurricane forecast model ensembles, such as http://derecho.math.uwm.edu/models/ & http://www.ral.ucar.edu/hurricanes/realtime/current/,
you can judge the “confidence” of the models by the grouping of the plotted tracks. If the plots are tightly grouped together, you can have “high confidence” in the reliability of the track and if the timing given by the plots agree, that also. The narrower the spread, the greater the confidence, and the wider the spread, the lesser the confidence. Some tracks will be obviously wrong, those you can dismiss. If the forecast tracks go look like they were written by a drunken spider, with paths going in every direction at once, that storm is heading nowhere fast.

Theoretically Tropical Storms will lose strength over land. The 1997 version of Danny (which came up I-65 reached Birmingham and then turned East heading along I-20 towards Atlanta, as if He knew what he was doing) forgot this and strengthened while over the swamps of South Carolina and then moved into the Atlantic as a rejuvenated system heading for New England. The theory at that time was that the swamps were so warm and humid that the storm “thought” it was over the sea. Now they say it was due to the effects a frontal system closely following the storm. I always preferred the first explanation, as it seemed more logical, if not niftier.

Storms named “Danny” and I are old companions, incidentally. In 1985 I accidentally managed to intercept Hurricane Danny a few hours after it struck Louisiana. I remember the feeder bands passing with heavy rain and gusts, and then it calming and clearing in between waves. “Looks like it can’t decide whether it’s coming or going” said the old guy at a truck stop where I was refueling. I also remember making a ham sandwich for an old dog at a rest stop. Old Shep looked hungry, so I fixed him one. He woofed it down, thanked me kindly and then disappeared into the mist.

If a storm strikes just West of Alabama, expect sorry weather. If it strikes just East of Alabama, expect dry weather and lowering humidity, as the storm drags the moisture away with it.

If a 120 MPH storm is moving North at 20 MPH the wind field around the eye will be effected as follows. The winds on the Eastern side combine and are in effect 140 MPH, while the winds to the West subtract and are in effect 100 MPH. This is the “fast moving hurricane rule”.

If the Eastern Pacific Basin is active, the Atlantic Basin will be quiet & if the Atlantic Basin is active the Eastern Pacific Basin will be quiet.

Category 5 storms have never occurred in both the Atlantic & Pacific Basins in the same year.

Hurricanes can cross Central America from either the Atlantic or Pacific Basins, enter the other Basin and restrengthen and be renamed. The last being in 1996 when Category 1 Hurricane Cesar which scraped Northern South America, crossed Central America & restrenghtened into Category 4 Hurricane Douglas.

Then there is the case of 1961’s Hurricane Hattie, which formed in the Caribbean, stuck Central America on Halloween, dissipated, then after reaching the Pacific, her remnants helped generate Tropical Storm Simone on November 1. Simone then turned Northwest striking Southern Mexico on November 2, dissipated and her remnants crossed Mexico, entering the Gulf of Mexico. These remnants in turn helped generate Tropical Storm Inga, which dissipated on November 8.

Alphabetical name position can’t be used as an indicator of possible storm strength. Andrew and Opal, both unruly guests, with names toward the opposite ends of the alphabet, are good examples.

Never underestimate the potential impacts of late season storms. Category 5 Hurricane Mitch was active from October 22 – November 5, 1998, with maximum sustained winds of 180 MPH. This storm struck Central America, Yucatán Peninsula & South Florida causing 6.2 billion dollars in damage and caused 11,000 deaths.

Remember that winds do not blow OUT of a hurricane; they are drawn INTO the storm in a spiraling motion. By factoring in the Coriolis Effect of the Earth’s rotation and the counter-effects of surface friction you can determine the general direction of any tropical storm or non-tropical low pressure center using the surface wind direction as follows:

Wind Direction Storm Center Location

South North West
Southeast West
East Southwest
Northeast South
North Southeast
Northwest East
West Northeast
Southwest North

Calm winds suddenly occurring during a hurricane indicates the eye is over you. The winds will return just as suddenly, often stronger in the opposite direction.

My sister’s family was living at Clark Air Force Base in the Philippines in 1974, when Typhoon Bidang passed directly over. When the winds suddenly died down they knew they were in the eye. Suddenly there was a knock on the door and opening it she found a delivery van with the furniture she had ordered. The Filipinos crew unloaded everything, said “thank you” and drove off into the darkness as the rear of the eyewall appeared and began blowing at full force.

NHC Hurricane Tracking Chart PDF’s

Here are handy hurricane tracking charts from the National Hurricane Center.

For the Atlantic Ocean: http://www.nhc.noaa.gov/pdf/tracking_chart_atlantic.pdf
For the Pacific Ocean: http://www.nhc.noaa.gov/pdf/tracking_chart_epacific.pdf

Someone once asked me “why do you bother tracking the Pacific ones?” For practice, so that when the Atlantic ones do appear you are already ahead of the game experience wise.

Let’s Nerd It Up!

In last month’s article “Zone Assessment For Emergency Preparedness And Mitigation”, I, as is normally the case, reviewed the article and deleted anything that could be offensive, get me or ALERT sued, tarred and feathered or seems too nerdy, verbose or out totally disconnected with ALERT’s purpose or mission.

Most omissions are simply to cut down on newsletter size, as I can have a tendency to “run on”,

In talking with a dear friend and loyal reader, I mentioned some of what I left out of the article, as it seem too nerdy, and it was suggested that perhaps the nerdiness would have been a worthy addition to the piece.

Ever wanting to please our audience, beginning where I left off, here are those missing gems!

“I know home is on a 220 degree compass bearing if I had to hike overland through areas where all normal landmarks have been obliterated.

However, I would not head on a direct compass heading. There are several reasons for this.

One reason is that unless one has the destination in sight, if one heads directly towards a distant object chances are excellent, due to avoiding obstacles and other factors, that you will miss the target either to the right or to the left. Which way do you turn?

A second reason for not taking a direct route is that without a visible target; even under perfect conditions no human can walk a straight line over a long distance. Even if your compass heading is correct, there is a tendency to gradually drift sideways, which is how people end up walking in circles.

Humans will drift to the right if right handed and left if left handed, a phenomena known as “lateral drift”.

By deliberately introducing a predictable error, in this case heading on a slightly more Northerly course of 245 degrees, to the right, you can eliminate one wrong direction, since you purposely veered to the right, you will know that your target is to the left of you.

This is actually using an old, almost forgotten, navigation technique of the pioneers, called “Off Aiming”.

Using the old pioneer methods I would use a “Baseline”, “Handrail” and “Backstop”.

A “Baseline” is a feature or landmark you identify to mark your starting point in case you have to reverse course and head back.

I work on Red Mountain which would be my “Baseline”. Red Mountain is a hard feature to miss.

Any road I could use to go in the desired direction I would use as a “Handrail”, or an easy path in the desired direction. When I reached Green Springs, I’m on target, and will turn left, which is South. If I reach I-65, my “Backstop” or a prominent landmark which lies beyond my target, I woul know that I have overshot, and would backtrack on a reverse course until I reached Green Springs again and then I would turn right towards the South.

Another factor, if it were a very long distance, is “magnetic declination”, which is where the magnetic North on a compass and the geographic North on a map do not match, since the poles are not located at the same location. The geographic pole is at the center of the Earth’s axis of rotation, the Magnetic North is in Arctic Ocean North of Canada.

In the Birmingham area all magnetic compasses are off 3.34 degrees to the West. So you set the compass North a little over 3 degrees to the East to get true North. In cases of small areal coverage this doesn’t matter, over long distances it would, as the effect of the error magnifies with increasing distance.

This magnetic declination error is increasing over time as the magnetic pole is shifting North Westward due to “Polar Drift”.

The Earth has a molten iron core. Variations in the flow of the molten iron in the outer core cause changes in the orientation of Earth’s magnetic field, and the position of the magnetic north and south poles.

The pole drifts considerably each day, and since 2007 it moves about 34 to 37 miles per year towards Asiatic Russia as a result of this phenomenon.

For reasons not fully understood this drift is increasing.

With all this said one might ask “why not just use a GPS or phone app?”

That’s exactly what I would do – if they work. If they don’t, I already have my backup plan.”

So there you go. With these gems and nuggets of wisdom you have now been officially nerded up.

Mark’s Almanac

Originally the fourth Roman Month, June at one time had 29 days, until Julius Caesar in a glow of inspiration added the 30th day.

What June was named for is uncertain. Some say it was named for Juno, wife & sister of Jupiter. Juno was the goddess of marriage and a married couple’s household, so some consider it good luck to be married in this month, which is why June has become a month for so many marriages.

The beginning of meteorological Summer is June 1.

Storm activity retains many of the characteristics of spring, but more and more the pattern takes on the summer pattern of pop-up thunderstorms.

Hurricane season begins, June 1, however June hurricanes are usually small and of minor intensity, occurring roughly once every two years.

The centers for June Tropical Cyclone activity are the extreme Western Caribbean, with the storm tracks striking the Yucatan or veering toward Western Florida & the Southwestern Gulf of Mexico, with other storm tracks aiming toward the Mexican mainland.

The center of maximum tornadic activity shifts northward over Kansas and Iowa. Activity in Texas and Oklahoma dies down. There is a 5% decrease in tornadic activity over the May average & by June 4th 50% of the years tornadoes have occurred.

Days continue to grow longer as the Sun’s angle above the noonday horizon increases from 78.5 degrees at the beginning of the month to maximum of 79.9 on Summer Solstice on June 21 and then lowering to 79.6 degrees at the month’s end. Daylight increases from 14 hours 14 minutes on June 1 to the maximum daylight of 14 hours 23 minutes at Summer Solstice on June 21 and then decreases to 14 hours 21 minutes on June 30.

Sunrise and sunset times for Birmingham are:

June 1 Sunrise 5:38 AM Sunset 7:52 PM
June 15 Sunrise 5:37 AM Sunset 7:59 PM
June 30 Sunrise 5:40 AM Sunset 8:01 PM

Looking towards the sky, at the beginning of the month Mercury is hidden deep in the sunset. He will emerge into the evening sky passing very close to Mars on June 18.

On June 23 Mercury will be at “Mercury at Greatest Eastern Elongation” or his highest point above the horizon 25.2 degrees from the Sun. This is the best time to view. Look for the planet low in the western sky just after sunset.

Brilliant Venus, magnitude -3.9, is buried very low in bright dawn. About 15 or 20 minutes before sunrise, scan for it with binoculars a little above the east to east-northeast horizon.

Mars, magnitude +1.7 near the feet of Gemini, is low in the west during and shortly after dusk.

Mars will pass just North of the Moon on June 5.

Jupiter, magnitude –2.6 in the eastern leg of Ophiuchus, The Serpent Bearer, rises in the southeast in late twilight. He shines highest in the south around 2 AM.

On June 10 Jupiter will be at “Opposition” or its closest approach to Earth and its face will be fully illuminated by the Sun. He will be brighter than any other time of the year and will be visible all night long.

This is the best time to view and photograph Jupiter and its moons. A medium-sized telescope should be able to show you some of the details in Jupiter’s cloud bands. A good pair of binoculars should allow you to see Jupiter’s four largest moons, Io, Europa, Callisto and Ganymede, appearing as bright dots on either side of the planet. Each night their positions will shift as they continue a waltz that has been going on for millennia uncounted.

On June 16 Jupiter will pass just to the South of the Moon.

Saturn, magnitude +0.3, in Sagittarius, rises around 11 or midnight. In the hours before dawn, He is the steady, pale yellowish “star” about 30° or three fists at arm’s length left of Jupiter.

Saturn will pass very close to Moon on June 18.

Uranus is hidden in the glow of the dawn.

Neptune, magnitude 7.9, in Aquarius, is low in the east-southeast before the beginning of dawn.

New Moon will occur June 3 at 5:02 AM CDT or 10:02 UTC. This is the best time of the month to observe faint objects such as galaxies and star clusters because there is no moonlight to interfere.

The Moon will be at Perigee, or her closest point from the Earth on June 7 at a distance of 228980 Miles.

Also on June 7, he Moon will pass very close, 0.2° of the Beehive Star Cluster or Praesepe, also known as Messier 44, a naked eye open star cluster in the constellation Cancer at 2:19 AM CDT.

Don’t ask me how to pronounce Praesepe. I’ve been trying to figure that one out for 50 years.

June’s Full Moon is “Strawberry Moon” in Native American folklore. This will occur on June 17 at 3:31 AM CDT or 8:31 UTC June 28. It is called “Strawberry Moon” for it signals the time to start harvesting strawberries, as it is peak strawberry ripening time. Other names are “Rose Moon” & “Honey Moon”.

Summer Solstice will occur at 10:54 AM CDT or 10:54 UTC on June 21. The North Pole of the earth will be tilted toward the Sun, which will have reached its northernmost position in the sky and will be directly over the Tropic of Cancer at 23.44 degrees north latitude. This is the first day of summer in the Northern Hemisphere and the first day of winter in the Southern Hemisphere.

The Moon will be at Apogee, or her farthest point from the Earth on June 22 at a distance of 251375 Miles.

The June Bootids Meteor Shower will occur from June 26th until July 2nd. It peaks on June 27th. Normally the shower is very weak, with a Zenith Hourly Rate or ZHR of 1 or 2, but occasional outbursts produce a hundred or more meteors per hour. The source of the June Bootids is Comet 7P/Pons-Winnecke, which orbits the Sun once every 6.37 years.

The Moon, being two days after Last Quarter will not pose a major problem.

3970 planets beyond our solar system have now been confirmed as of May 16, per NASA’s
Exoplanet Archive http://exoplanetarchive.ipac.caltech.edu/
