From Discovery Channel:
We are deeply saddened by the loss of Tim Samaras, his son Paul and their colleague Carl Young who died Friday, May 31st doing what they love: chasing storms.

Chasing storms had been a part of Tim Samaras's life for over 25 years. Ten years ago, Tim developed his own tornado probes to record meteorological data inside of tornadoes.

Inspired by a two-month adventure chasing storms across the Great Plains, Carl Young left a career in Hollywood to study tornado dynamics and ultimately earn a masters degree in atmospheric science from the University of Nevada, Reno.

While attending a meteorological conference, Carl met Tim, who encouraged him to collect meteorological data from inside tornadoes as the principal focus of his thesis research.

Every spring since 2003, the two headed out together and tracked down over 125 tornadoes. Their mission was to help understand why tornadoes form in order to increase warning times in Tornado Alley.

Tim and Carl's work was the subject of Discovery Channel's Storm Chasers series, which premiered on October 17, 2007 and ran for five seasons.

Our thoughts and prayers go out to Tim and Carl's friends and families.



From National Geographic
Tim Samaras, one of the world's best-known storm chasers, died in Friday's El Reno, Oklahoma, tornado, along with his 24-year-old son, a gifted filmmaker, according to a statement from Samaras's brother.

"They all unfortunately passed away but doing what they LOVED," Jim Samaras, Tim's brother, wrote on Facebook, saying that storm chaser Carl Young was also killed. "I look at it that he is in the 'big tornado in the sky.'"

. . . Samaras's interest in tornadoes began when he was six, after he saw the movie The Wizard of Oz. For the past 20 years, he spent May and June traveling through Tornado Alley, an area that has the highest frequency of tornadoes in the world. He worked with his son Paul, who was known for capturing cyclones on camera.

From CNN
Friday's tornado took a sudden turn that surprised many observers, CNN meteorologist Chad Myers said.

"It was a wobbler. And it was big. ... I think the left-hand turn made a big difference on how this thing was chased as well and why people were killed and why people were injured in their vehicles," he said. "A vehicle is not a place to be in any tornado, especially a big one like that, and those men doing their job, those field scientists out there doing their jobs, were killed in the process."

Tim Samaras founded TWISTEX, the Tactical Weather Instrumented Sampling in Tornadoes Experiment, to help learn more about tornadoes and increase lead time for warnings, according to the official website.

. . . Doug Kiesling, a videographer who chases storms and calls himself "The Weather Paparazzi," said the three men were more than storm chasers. "They're researchers," he said.

"This thing is really shaking up everyone in the chasing community," he said. "We knew this day would happen someday, but nobody would imagine that it would happen to Tim. Tim was one of the safest people to go out there. ... He's had close calls, but he's always had an escape route."

Raging Bush Fires in Australia

Photobucket

Horrible wildfires are raging in Australia right now, endangering thousands and destroying homes and property. We can only imagine what is happening to the creatures who live in the Australian Bush as well. I hope their weather breaks soon and they get some cooling rain.

Time Magazine Slideshow

From Discover News:
The record-breaking temperatures have fueled brushfires across Australia. The L.A. Times has reported that swaths of the country face “some of the most dangerous conditions for fires on record.” As of today, 140 brushfires were reported in the state of New South Wales alone. And a NASA map of active fires detected by satellite sensors showed many more across the entire country.
 On Monday, the average high temperature across all of Australia was 104.6 degrees—a record, according to the Australian Bureau of Meteorology. This continues a persistent trend. For the September through December period, the average Australian maximum temperature was the highest on record.

What is a "Derecho" Anyway?


Photobucket
"The Line Storm," by John Steuart Curry, 1897-1946


Lately there have been several lines of devastating storms moving through the Ohio Valley, and meteorologists have been referring to them as a "derecho." I've lived in the U.S. all my life and never heard that term, even though we routinely get straight-line winds and severe weather here in the Southeast. They never mentioned it last year on the day of the April tornadoes, although that line of storms lasted for hundreds of miles, which makes me think that tornadoes trump derechos. Officially, the terrible line of storms that passed over the Northeast last week were not part of a derecho:



LA Times Story
Joey Picca , a meteorologist with the National Weather Service, said in a telephone interview with the Los Angeles Times from his office in Upton N.Y. on Long Island. “What we saw yesterday wasn’t a derecho in the traditional sense because it wasn’t widespread enough. Although we did see a large line of thunderstorms, it was lacking the true intensity you would like to see in a derecho.”
A derecho is defined as an event that has wind gusts of at least 58 mph and leaves a swath of damage for a minimum of 240 miles, according to the U.S. Storm Prediction Center.

So the phenomenon is actually rare, but with global warming raising the mercury it it could certainly happen again, so let's get educated by going directly to NOAA for the definition:
Definition of a derecho
A derecho (pronounced similar to "deh-REY-cho" in English, or pronounced phonetically as "") is a widespread, long-lived wind storm that is associated with a band of rapidly moving showers or thunderstorms. Although a derecho can produce destruction similar to that of tornadoes, the damage typically is directed in one direction along a relatively straight swath. As a result, the term "straight-line wind damage" sometimes is used to describe derecho damage. By definition, if the wind damage swath extends more than 240 miles (about 400 kilometers) and includes wind gusts of at least 58 mph (93 km/h) or greater along most of its length, then the event may be classified as a derecho.
Origin of the term "derecho"
The word "derecho" was coined by Dr. Gustavus Hinrichs, a physics professor at the University of Iowa, in a paper published in the American Meteorological Journal in 1888. A defining excerpt from the paper can be seen in this figure showing a derecho crossing Iowa on July 31, 1877. Hinrichs chose this terminology for thunderstorm-induced straight-line winds as an analog to the word tornado.

"Derecho" is a Spanish word that can be defined as "direct" or "straight ahead." (Click here to hear a pronounciation of the word "derecho"). In contrast, the word "tornado" is thought by some, including Hinrichs, to have been derived from the Spanish word "tornar," which means "to turn." Because derecho is a Spanish word, the plural term is "derechos;" there is no letter "e" after the letter "o."


A web page about Gustavus Hinrichs has been created by Ray Wolf of the Davenport, Iowa National Weather Service Forecast Office. The page provides information on Hinrichs' background, and on his development of the term "derecho" in the late 1800s. Wolf's page also briefly discusses how the term "derecho" has come into more common use in recent years.
