(L to R) Tim Samaras, Paul Samaras and Carl Young. |
By now, all have heard the
appalling news that storm researchers Tim Samaras, his son Paul, and Carl Young
lost their lives while studying the tornadic supercell thunderstorm that struck
the Oklahoma City area on Friday May 31, 2013.
Tim and Carl were my colleagues
and seasoned meteorologists involved in TWISTEX (Tactical Weather Instrumented
Sampling in/near Tornadoes Experiment) whose mission it is to sample aspects of
the environment near tornadoes. I’ve
known them for years.
I have been involved in storm
research and/or the storm chasing community since 1985. In this 28 year span, there had not been a
death and I know of no injuries among meteorologists studying tornadic storms,
until now. It will be several days
before the exact circumstances of this tragic loss become clear. But even before the storm that ravaged the
El Reno and Union City, OK areas occurred, many questions appeared in the media
about storm chasing, or storm observing in the field.
Reducing this issue down to its
core, emergency management personnel complain that storm chasers are clogging
roads and making it difficult for first responders to reach victims. This issue came to a head in Ellsworth
County KS April 14, 2012 as an EF4-rated tornado approached Salina.
Whether it is true that storm
chasers did indeed impede traffic in that and other cases, it’s clear that the
number of chasers out on the roads has dramatically increased in the last
decade. And some of these people engage
in foolhardy and dangerous behavior. The
question is “why?”
From my perspective, as a
professor of meteorology, the term “storm chasing” means what it always has
meant to atmospheric scientists who study storms in the field. It means interweaving meteorological
reasoning and forecasting skills for the purpose of understanding severe
thunderstorms in general, and tornadic supercells in particular.
It’s enough to say that the early
forays of meteorologists studying severe storms in the field in the 1960s and
1970s continued into the 1980s, and 1990s.
Eventually, their missions split into two tracks. On the one hand, in the middle to late 1990s
and early 2000s large National Science Foundation-funded projects like VORTEX
(Verification of Rotation in Tornadoes Experiment), STEPS (Severe Thunderstorm
Electrification and Precipitation Study), TWISTEX and others involved field
efforts bringing many research meteorologists and instrument platforms into the
field to surround tornadic supercells or severe thunderstorms. I was involved at a minor level in the first
and more actively in the second.
The second track relates to more
of what I do as a meteorologist.
Initially, I was drawn to study these storms because they happen in
California too. So, since I am a weather
forecaster by training, what better way to understand how weather patterns
contribute to the ingredients of severe storms than by immersing myself in a
large “inquiry-based” personal research experience?
In my case, bringing this
knowledge of ingredients, burned into my psyche by having to forecast them,
back to California has helped meteorologists there understand the patterns that
are liable to produce favorable conditions for tornadic supercells. Other meteorologist chasers have their own set
of predetermined goals in observing storms in the field. All of us are admittedly united in a
fascination with these storms.
What is important to note is that
no matter what their mission, meteorologists studying storms in the field
contribute to the storm observing process.
All my colleagues who do this have ways of contacting the National
Weather Service quickly when tornadoes are forming. This has led to an increase in the warning
time. For example, such observations
were a key in preventing injuries and loss of life for the Greensburg KS
tornado on May 4, 2007.
In 1996, the film “Twister” popularized
the notion of chasing storms to immerse oneself in a tornado’s circulation. The
film’s chase teams were loosely based upon the fleets of vehicles called
“Mobile Mesonets” in project VORTEX and the early chase forays by the National
Severe Storms Laboratory (NSSL) and Oklahoma University.
Except it was based upon a
fiction: that meteorologists purposefully drive into tornadoes. That fiction, I
believe, has combined with the trend in society for “extreme” behavior. This has encouraged literally hordes of
non-meteorologists many of whom who do not understand storm structure or
behavior, carrying cellular phone cameras into the field. This extreme behavior
is exemplified by cable network programs extolling groups of chasers who drive
vehicles that resemble Flash Gordon/Emperor Ming the Merciless’s space ship
into the path of tornadoes, screaming “tornado, tornado”.
What does this have to do with
Friday’s tragedy?
There were many chasers in the
field that day. A radar plot taken around
6:11 PM CDT about the time that a multiple vortex tornado was on the groundshows
dozens of red dots representing storm chasers or spotters or researchers who
were reporting their positions.
Undoubtedly there were many more.
Most of the meteorologists I know
who were out in the field that day are represented by the dots south and east
of the storm circulation. Many of them
contributed useful information to the National Weather Service in the form of
eyewitness accounts of the tornado formation, that were not able to be detected
by the NWS radars in the Oklahoma City area.
Some of them were on instrumented vehicles that included mobile Doppler
Radar that also contributed to the excellent warnings issued for that tornado.
Most left the area when the storm’s circulation got
so intense that visibility became an issue.
They also navigated away from Oklahoma City so as not to clog roads at
commute time, or to contribute to the chaos that would develop there if a
tornado went into that heavily urbanized area.
In the coming days, we’ll learn
more about the decisions that Tim’s group made that day. It could be that he took some calculated
chances and was caught by the rapid northward motion of the tornado.
It would be a double tragedy if
his memory is besmirched by an assumption the he was seeking thrills or
personal publicity. He wasn’t. He was an active researcher contributing to
our knowledge.
But the fact remains that to
Emergency Management personnel a chaser is a chaser, whether he/she is a
meteorologist or not. While it’s clear
that meteorologists who chase know how not to interfere or know how to keep
major road stems free of traffic, it’s not clear that others do. This is an important issue that the storm
research/chaser/spotter community must face in the upcoming years.
Rest in peace, Tim, Paul and Carl.
