This increase seems to reflect the increase in size and frequency among large hurricanes that make landfall from the Gulf of Mexico.

Wed, 24 Jun 2009 14:00:00 EDT http://www.sciencedaily.com/releases/2009/06/090624093311.htm http://www.sciencedaily.com/releases/2009/03/090311111013.htm On March 14, 2008, a tornado swept through downtown Atlanta, its 130 mile-per-hour winds ripping holes in the roof of the Georgia Dome, blowing out office windows, and trashing parts of Centennial Olympic Park. It was an event so rare in an urban landscape that researchers immediately began to examine NASA satellite data and historical archives to see what weather and climatological ingredients may have combined to brew such a storm. Wed, 18 Mar 2009 23:00:00 EDT http://www.sciencedaily.com/releases/2009/03/090311111013.htm http://www.sciencedaily.com/releases/2009/03/090310115809.htm The U.S. National Weather Service has analyzed forecasting performance and public response during the second deadliest tornado outbreak in U.S. history. The report addresses a key area of concern: why some people take cover while others try to ride out severe weather. Some people stay put during tornadoes, believing that 'bad things only happen to other people.' Wed, 11 Mar 2009 08:00:00 EDT http://www.sciencedaily.com/releases/2009/03/090310115809.htm http://www.sciencedaily.com/releases/2009/01/090102101136.htm One of the largest sources of uncertainty in weather prediction involves how microscale structures influence larger-scale phenomena. For instance, previous studies have demonstrated that the structure, dynamics, and evolution of thunderstorms are very sensitive to cloud microphysical parameters.

"We have already seen more than 115 tornado-related deaths, making this the deadliest tornado season since 1998," said a meteorologist at NOAA's Storm Prediction Center. "It is only the third time since the 1974 super tornado outbreak that there have been more than 100 tornado-related deaths during a single tornado season in the U.S.," a research meteorologist at NOAA's National Severe Storms Laboratory added.

And flooding in the Midwest has been at 100-year levels this spring. Wed, 04 Jun 2008 11:00:00 EDT http://www.sciencedaily.com/releases/2008/06/080602231312.htm http://www.sciencedaily.com/releases/2008/05/080508182435.htm Three hot-air balloons dropped asphalt shingles, lumber, sticks, leaves and pine needles onto a north Alabama landfill, so scientists could gather data needed to improve tornado warnings. The payloads dropped by the balloons were similar to the types of debris thrown into the air by tornados that touch the ground. Scientists hope the Doppler radar data collected will be a first step toward programming National Weather Service Doppler radar to recognize tornado debris, so more timely and precise tornado warnings might be issued.

Combining the land and the ocean temperatures, the overall global temperature ranked the second warmest for the month of March. Global temperature averages have been recorded since 1880. An analysis by NOAA's National Climatic Data Center shows that the average temperature for March in the contiguous United States ranked near average for the past 113 years. It was the 63rd warmest March since record-keeping began in the United States in 1895. The average global land temperature in March of 2008 was the warmest on record and ocean surface temperatures were the 13th warmest. Combining the land and the ocean temperatures, the overall global temperature ranked the second warmest for the month of March. Global temperature averages have been recorded since 1880.

Scientists are studying radar data from the early morning tornado to see if the radar signature from the debris is so distinctive that computers can be programmed to instantly recognize it, so more timely and precise warnings might be issued. Wed, 20 Feb 2008 11:00:00 EST http://www.sciencedaily.com/releases/2008/02/080217215726.htm http://www.sciencedaily.com/releases/2007/05/070514092301.htm With meteorologists concerned about a possible worldwide intensification of tornado activity, scientists are proposing a new approach to studying formation of twisters, which pack Earth's most violent winds. It involves forming microtornadoes under millimeter-scale crystalline "igloos" according to a recent article. Mon, 14 May 2007 17:00:00 EDT http://www.sciencedaily.com/releases/2007/05/070514092301.htm http://www.sciencedaily.com/releases/2006/06/060605082238.htm Iowa State University researchers and students will soon be chasing tornado data in the lab and across tornado alley. It's all part of a research project designed to increase scientists' basic understanding of wind storms and develop innovative ways to make homes and buildings stand up to tornadoes, microburst thunderstorms, hurricanes and gust fronts.

Normally, during the most active tornado months of April, May and June, 61 percent of all tornado fatalities or an average of 52 deaths occur.

The National Center for Atmospheric Research helped develop the Rapid-Scan Doppler on Wheels and a powerful technique to analyze its data in 3-D.

Sat, 11 Jun 2005 02:00:00 EDT http://www.sciencedaily.com/releases/2005/06/050611003815.htm http://www.sciencedaily.com/releases/2005/06/050603074856.htm A new Doppler radar instrument that can scan tornadoes every five to 10 seconds is prowling the Great Plains this spring in search of its first close-up twister. Newly enhanced for season-long thunderstorm tracking, the radar promises the most complete picture to date of tornado evolution, allowing for better tornado prediction in the future.

The twist is that these tornadoes are more likely to form late at night and in colder months. Tue, 12 Apr 2005 08:00:00 EDT http://www.sciencedaily.com/releases/2005/04/050411100716.htm http://www.sciencedaily.com/releases/2005/01/050104115613.htm The total number of tornadoes reported in the United States reached a record high during the year 2004, surpassing the previous record by almost 300, according to officials at the NOAA Storm Prediction Center in Norman, Okla.

However, the pattern of destruction that occurs when a tornado interacts with a building is predictable, and that makes it preventable, according to University of Arkansas researcher Panneer Selvam.

Researchers still don't know for sure. Current wind speeds for hurricanes over land are estimates based on the damage they leave in their path. But all that will change this April, when Texas A&M University unveils its new mobile radar system, SMART-R.

One year later, NASA researcher Steve Goodman demonstrates how another foul-weather hazard -- lightning -- could be the key to predicting such devastating storms.

Is this a psychic prediction? No. According to the National Severe Storm Laboratory, these statistics are the average for the U.S. But they are statistics that Paneer Selvam, a civil engineering professor at the University of Arkansas, wants to change.
