Riders on the Storm - Chasing Tornados
In my last posting on April 8, I mentioned a few of my close encounters with major thunderstorms and tornados. This came about after watching videos about tornados and the exploits of storm chasers in “Tornado Alley” of the Great Plains. These storms are created when dry cold air moving south from Canada meets warm moist air traveling north from the Gulf of Mexico.
During the spring and early summer storm chasers set out in search of “towers,” the looming cumulus clouds that can be the first stage in the formation of a supercell storm. Storm chasing often involves driving hundreds of miles in search of active severe thunderstorms. Many chasers spend a significant amount of time forecasting, both before going on the road as well as during the chase, utilizing various sources for weather data. Once located the serious chasers employ Doppler radar to spot rotation that spells the potential birth of a tornado. The idea is to get as close to the storm – even in its direct path – as safety will allow in order to take photographs, make videos, and record data. Many storm chasers are trained meteorologists seeking to learn more about how these storms work. Others are simply in it for the chase and bragging rights, and perhaps earning a modest salary selling data, video, and photography they collect.
One has to know what one is looking for and what to do when a tornado is spotted. Working on the ground, however, these spotters can provide definitive information whether a storm seen from a distance is a supercell and provide visual information on the storm's shape and structure, including updraft towers, rotation in the wall cloud, striations, strength of inflow, and position of the precipitation core in relation to the wall cloud. A vast majority of tornadoes occur with a wall cloud on the backside of a supercell. Most of these signs – temperature, humidity or pressure inside a tornado – will not show up on Doppler radar. Spotters also look for ground disturbances beneath the wall cloud as a tornado forms not from the clouds down, but from the ground up; it might already be on the ground before the funnel becomes visible.
There are six categories of tornado – EF0-EF5 – on the Enhanced Fugita Scale established in 2007 and based on estimated wind speeds and relative damage. The previous Fugita Scale established in 1971 was based solely on the amount of damage. The NWS is the only federal agency with authority to provide official tornado EF Scale ratings based on the highest wind speed occurring within the damage path. Once again the NWS relies on ground spotters to ascertain this information. An EF0 tornado has winds estimated at 65-85 mph creating general light damage. An EF5 – the so-called “finger of God” – has wind speeds of over 200 mph causing devastating damage. The largest and strongest tornado on record was the EF5 El Reno wedge tornado occurring in Oklahoma on May 31, 2013. According to reports, it grew to a width of over 2.5 miles with a wind speed reaching 302 mph. Fortunately the storm occurred mostly in open country and so damage and lost of life was relatively low for such an intense storm. Nevertheless, 20 people lost their lives and over 100 others were injured during its 40-minute rampage. There was another EF5 tornado in and around Oklahoma City eleven day earlier with 215 mph wind killing 24 people and causing extensive and widespread damage.
Three of the El Reno fatalities were experienced professional storm chasers, the first known chaser deaths inflicted directly by weather. Several other chasers were also struck and some injured by this tornado and its parent supercell's rear flank downdraft. The three died when the storm suddenly changed direction and their vehicle was destroyed while attempting to place a TOtable Tornado Observatory (TOTO), on which the Dorothy packet in the Twister film was based, in the damage path of that historic tornado. This tragedy may have been prevented had they been equipped with mobile Doppler radar which has now become proforma in serious storm chasing circles as it provides near real-time updates on intensity and movement of the developing storm.

And the Stormwatch Brews
And the stormwatch brews . At the heels of a soft prayer – Ian Anderson, “Dun Ringill”
I have been fascinated by powerful thunderstorms since I was a little kid. The more lightning and thunder the better. I can think of no better way to fall asleep than lying in bed listening to the approach of a thunderstorm knowing I am safe inside. Yet sometimes these storms pack a more powerful punch than first anticipated and one is forced to pay close attention in case they turn into some far more ominous than brief displays of lightning and rolling thunder. Having grown up in the Midwest I have learned to have a healthy respect for tornados and what to do should they develop.
I recall living through several tornadoes watches and warnings, the most memorable being the broad outbreak through the upper Midwest on Palm Sunday, April 11, 1965, when my family was living in Madison, Wisconsin. We had gone to visit friends after church and I well remember the sickly green overcast that is a telltale sign of the potential for a developing tornado. We never did see any funnels clouds that day, but this outbreak produced 55 confirmed tornadoes, the fourth deadliest tornado outbreak in US history, killing 271 people and injuring 1,500.
I did not see my first tornado until four years later when I was visiting an old school chum then living in Texas. It was the summer of 1969 and I joined his family for dinner one evening at a local restaurant. While we were there we learned that a severe thunderstorm warning and tornado watch had been issued for the area. The sky was darkening and the wind was picking up outside, but we did not see any reason to be too concerned. But we kept an eye on the sky just in case. When leaving the restaurant, however, we looked toward the sunset in the west where we spotted what proved to be a multi-vortex F3 wedge tornado slowly moving toward the north. Fortunately we were not in any danger and so we stood there for quite some time mesmerized by the storm. It was fairly short lived and did not cause any significant property damage and no major injuries or fatalities. Still, it was a sight I would not soon forget.
During the summer of 1987 my wife and six year old son Ian found ourselves at the summit of Brasstown Bald, at 4,784 feet Georgia’s highest elevation located in the Chattahoochee-Oconee National Forest. We visited the observation center one afternoon for its refreshing temperatures during an otherwise very warm and humid summer day, and to enjoy the breathtaking 360-degree views into Tennessee and the two Carolinas. On this particular visit we observed a massive anvil-shaped thunderhead advancing in our direction. Deciding it unwise to be caught out in the storm this high up on the mountain, we decided to remain on the summit inside the observation center until the storm had passed. It is a good thing we did. As the storm approached we watched as bolts of lightning danced through the thunderhead and spiked the valley floor. It was a sight to behold. Before long the summit was completely enveloped by the storm. Lightning flashed almost non stop all around us and we could hear the sizzle of electricity in the air. Our little boy was none to happy but I explained to him that we were safe inside and what a special thing it was to witness a storm up close. I’m not sure he was convinced but he rode out the storm being as brave as he could.There was another opportunity to feel the full power of a thunderstorm, and a massive one at that. On the evening of July 4, 1999, I attended the local holiday fireworks in Colebrook, New Hampshire. It had been a beautiful summer day to be exploring the Connecticut River headwaters hard on the Canadian/Québec frontier although the temperatures were in the 90s with high humidity. Afterwards I enjoyed a fine dinner at my favorite local lodge and a couple nightcaps in the tavern where the talk seemed to be focused on some predicted heavy weather to arrive overnight. Before turning in for the night I stepped outside for a breath of fresh air and I quickly realized that the atmosphere had turned stagnant with no noticeable wind. I retired upstairs to read after mapping out a trip into Maine the following day, hoping for more favorable weather. The verdict was not yet in. Before hitting the hay I stepped outside again around 1am and notice some lightning flashes in the distant west beyond the Canadian frontier. It looked indeed like we might get a storm overnight. At the time I did not realize what an understatement that was.
During the pre-dawn hours of that July 4th, thunderstorms were cropping up out in the Dakotas, and they eventually organized into a bow echo on Doppler radar indicating a building derecho – a widespread and long-lived straight-line wind storm or quasi-linear convective system accompanied by violent down bursts. Damaging winds were occurring by the time the storm began moving across Minnesota to become known as the "Boundary Waters - Canadian Derecho." It would last over 22 hours, travel more than 1300 miles at an average speed of almost 60 mph, resulting in widespread devastation and numerous casualties in both Canada and the United States. Little did I know that evening that before morning it would have crossed Ontario and moved into western Québec north of Montréal with up to 6000 lightning strikes per hour and widespread wind damage. It arrived in the Montréal metropolitan area at 2 to 3 am causing serious damage before reeking havoc on the Eastern Townships of Québec and neighboring area of northern New England with winds upward of 90 mph. A tree farm in Sawyerville, Québec just a few miles northwest of where I was sleeping had most of its 2000-3000 trees destroyed.
I was awoken by the storm in the pre-dawn hours of July 5th. The wind was rattling the windows in my room and the sky were illuminated by almost constant flashes of lightning while a cacophony of thunder boomed loudly over the sound of the wind. I climbed out of bed and looked out at a lake whipped into a frothy brew. Trees were swaying in the wind and the lawn was scattered with downed branches and leaves although the roar of the storm's winds was so loud no one could have heard trees snapping or falling to the ground. There was little chance to go back to sleep so I sat by the window and watched the storm as it continued its eastward journey.
The full impact of the storm became evident once the sun began to rise. The power was out to a wide swath of southern Québec and northern Vermont and New Hampshire, and after a cold breakfast at the lodge I took a drive to have a look around. Hundreds, if not thousands, of trees were down and branches were scattered everywhere. Wind gusts to 90 mph were measured near Colebrook and around the North Country. I crossed the border into Canada where Hydro-Québec reported that from the Montréal area into the Eastern Townships 600,000 customers had lost electrical power. Power would remain out for over a week in some places. I eventually crossed back into the USA at Coburg Gore, Maine which also experienced the destructive derecho winds. I found more trees splayed on the ground the result of vertical wind shear and micro-downbursts embedded in a broader swath of strong but less severe winds produced by the parent convective system. The derecho continued to cause damage across central and southern Maine before dissipating when it reached the Atlantic coast. The very long-lived “Boundary Waters-Canadian Derecho” was one of farthest northern derechos to have been recorded having destroyed hundreds of square miles of trees. Two people were killed and 70 were injured, almost all of them the result of falling trees or tree limbs. Despite all the damage, I consider myself lucky to have experience the full impact of such a historic derecho.
The tornado then struck the US Department of Agriculture Research Center, causing an estimated $41 million in damage to buildings and research documents. Before it was over 861 residential homes, 560 vehicles, and at least 23 commercial businesses were destroyed or damaged at an estimate of over $73 million. The September 24, 2001 tornado is noteworthy because of its nearly 17 mile track, and it remains the only long-track event with an intensity of F3 or greater to directly impact on the greater Washington, DC, and adjacent suburban Maryland region since then.
Recently I have been watching videos about tornados and the exploits of storm chasers, that fellowship of adrenalin-fuel meteorology junkies who seek out and track developing thunderstorm systems in “Tornado Alley” of the Great Plains – a reference to the region in the US Midwest that sees the most tornado activity. This is nothing I have ever done on my own save the occasional detour to check out areas recently impacted by severe storms. But I have long been curious what it would be like to be on the front line. I will have more to say about this is a future posting. So stay tuned.

Babyn Yar: Putin is Abusing and Distorting the Memory of the Holocaust
I read with horror and profound sadness the reports that the criminal Russian missile and aerial attacks on the Ukrainian capital Kyiv and the damage inflicted on the Babyn Yar memorial to victims of the Holocaust. It was in a large ravine located there that over the course of two days in early September 1941 members of a Nazi German Einsatzgruppe murdered almost 34,000 Ukrainian Jewish men, women, and children. The Nazi authorities continued to perpetrate horrendous crimes at Babyn Yar, using it as a mass grave to dispose of up to 100,000 bodies of Jews, Roma, Ukrainian civilians and Soviet prisoners of war, until Kyiv was liberated by the Soviets Red Army in 1943, but not before the retreating Germans bulldozed the ravine and burned the bodies to erase the evidence of their horrific crimes. Since the war Babyn Yar has become one of the most important memorial sites of the Holocaust and holds a special place in the hearts of Ukraine, a country with a large Jewish population (perhaps as many as 360,000), and a Jewish president. President Volodymyr Zelensky has long pledged to preserve his country’s Holocaust sites, to remember the victims, and to secure the historical truth of what happened during that dark chapter of the country’s history.
The entire civilized world condemns these horrible and senseless attacks ordered by Russian president Vladimir Putin on the pretext that he would rid Ukraine of its “neo-Nazi” leaders with the expressed goal, the "denazification" of the country. Critics of Putin have condemned Putin’s delusional distortion and manipulation of the Holocaust to justify his criminal invasion of a sovereign and democratic country. Strange then he would attack and damage one of the most important memorials to Nazi crimes in Ukraine. Thankfully we now know that the iconic memorials in memorial park – a large menorah, a newly built synagogue, and a monument honoring Soviet citizens and prisoners of war who were murdered at the site, have not been damaged although a museum build was partially burned, and other damage occurred across the 140-acre memorial. President Zelensky perhaps summed up best the attack that was “beyond humanity.” "What is the point of saying 'never again' for 80 years, if the world stays silent when a bomb drops on the same site of Babyn Yar? At least 5 killed. History repeating . . . they have an order to erase our history. Erase our country. Erase us all."
The Russian attacks at the memorial site are significant in that they have been carried out by a country who suffered grievously when Nazi Germany invaded the former Soviet Union in June 1941. Before the German invaders were vanquished, nearly 27 million Soviet citizens had died, including 8.7 million military deaths, including members of President Zelensky’s own family who fought with the Red Army against the Nazis.
Only his grandfather survived. Numerous thousands were murdered by the Nazis at Babyn Yar. President Zelensky is correct. This unprovoked attack, in fact the entire war, goes “beyond humanity.” And to justify the invasion of a free and democratic country on the grounds that it is necessary for its “denazification” is an abuse and a distortion of the memory of the Holocaust.
Putin is following in the footsteps of his Soviet predecessors in trying to erase what history recalls of the murders at Babyn Yar. Just as the Nazis had done before their retreat, Soviet authorities tried to suppress evidence of crimes committed against Jews on what was then Soviet territory even though its own soldiers and citizens were slaughtered by the thousands there. Thankfully they failed, and with Ukraine gaining its independence following the collapse of the Soviet Union, Babyn Yar has taken its rightful place as one of the most important Holocaust remembrance sites.
I first became aware of what happened at Babyn Yar in the mid-1960s when I read Yevgeny Yevtushenko’s 1961 poem “Babi Yar” [the Russian spelling] which he wrote in Kyiv in 1961 after visiting the site. Recalling the Nazi atrocities committed there, Yevtushenko admitted later that he was surprised that it was published for it is a condemnation of all anti-Semitism, including that found in the Soviet Union. It came at a time when the Soviet authorities were using Babi Yar as a garbage pit; there was no memorial to the dead. Shame drove Yevtushenko to return to his hotel and write the poem, a poem about human suffering that overshadows any politics. “It is very difficult to find words which are expressive enough. It was too much for words. Words are too weak.” Nevertheless, he persisted.
Are international, by inner nature.
But often those whose hands are steeped in filth
Abused your purest name, in name of hatred.
I know the kindness of my native land.
How vile, that without the slightest quiver
The anti-Semite have proclaimed themselves
The “Union of the Russian People!”
[ . . . . ]
Wild grasses rustle over Babi Yar,
The trees look sternly, as if passing judgement.
Here, silently, all screams, and, hat in hand,
I feel my hair changing shade to gray.
And I myself, like one long soundless scream
Above the thousands of thousands interred,
I’m every old man executed here,
As I am every child murdered here.
No fiber of my body will forget this.
May “Internationale” thunder and ring *3*
When, for all time, is buried and forgotten
The last of anti-Semites on this earth.
There is no Jewish blood that’s blood of mine,
But, hated with a passion that’s corrosive
Am I by anti-Semites like a Jew.
And that is why I call myself a Russian!
Now, once again, Putin aggression against Ukraine is an attempt to abuse and distort history. And perhaps once again words are too weak to express what is felt deep in the heart. But we must try. All of us!! It is time to say “Never Again” and mean it!
