NASA Sees System 91S Struggling
2014-01-31 14:20:56

NASA/Goddard Space Flight Center NASA's Aqua satellite provided infrared data on System 91S in the Mozambique Channel that showed a system battered by wind shear, stretched out, with broken convection. A false-colored infrared image was created at the Naval Research Laboratory in Washington, D.C. using infrared data from the MODIS instrument aboard NASA's Aqua satellite on January 31 at 11:05 UTC/6:05 a.m. EST. The MODIS image showed the strongest thunderstorms associated with System...

Global Warming Driving Severe Thunderstorms

[ Watch the Video: Thunderstorms Could Become More Severe In The US ] redOrbit Staff & Wire Reports - Your Universe Online The risk of severe thunderstorms capable of producing extreme amounts of precipitation and tornadoes is expected to increase in frequency in the US, according to new research published this week in the journal Proceedings of the National Academy of Sciences. Weather disasters, including severe thunderstorms, caused more than $1 billion worth of economic...

Cyclone Evan's Decline Shown With Time Series Of Infrared NASA Images 715490main_20121219-EVANfinal-AIRS-FULL

NASA Cyclone Evan is now far south of Fiji and wind shear and cooler sea surface temperatures have been taking their toll on the storm and weakening it. Infrared data from NASA's Aqua satellite has shown a quick decline in the storm's structure over one day. A time series of infrared images from the Atmospheric Infrared Sounder (AIRS) instrument that flies aboard NASA's Aqua satellite showed changes in intense thunderstorms within Cyclone Evan between Dec. 18 and Dec. 19. Over a time...

The active hurricane season could get even busier due to the strengthening of the La Nina climate system, the National Oceanic and Atmospheric Administration (NOAA) said in an update on Thursday. The update comes as Texas residents are cleaning up from the flooding rains that swept through from Tropical Storm Hermine. La Nina was reported to be developing a month ago and has strengthened throughout August. It appears likely to last through early 2011, NOAA's Climate Prediction Service said....

Gray Creech of NASA's Dryden Flight Research Center can remember August 2, 1985, as if it was yesterday. On that day 25 years ago the public affairs specialist was a young U.S. Air Force airman heading home on leave to North Carolina, flying out of Dallas Fort Worth International Airport. "I was looking out my window, sitting at the end of the runway aboard the second airplane lined up to take off," said Creech. "I had a window seat and was looking out the window when I noticed some really,...

Wind shear strength determines whether pollution swells or saps storms New climate research reveals how wind shear -- the same atmospheric conditions that cause bumpy airplane rides -- affects how pollution contributes to isolated thunderstorm clouds. Under strong wind shear conditions, pollution hampers thunderhead formation. But with weak wind shear, pollution does the opposite and makes storms stronger. The work improves climate scientists' understanding of how aerosols -- tiny unseen...

DENVER, Nov. 3 /PRNewswire/ -- The U.S. Federal Aviation Administration (FAA) has purchased a WindTracer(R) lidar system from Lockheed Martin , which is being tested at the Las Vegas McCarran International Airport. The system is designed to improve flight safety and airport operational efficiency by providing advanced warning of wind hazards and wind shifts. Developed and produced by Lockheed Martin Coherent Technologies, the WindTracer system continuously scans the approach and departure...

Atmospheric waves that ripple through clouds could spin up tornadoes when a thunderstorm gets in the way, new research shows. Tornadoes generally form in the late spring when warming temperatures make the air unstable (though they've been known to pop up at other times of the year). The classic tornado-forming scenario features a layer of warm, moist air trapped under a layer of cold, dry air. If this balance is upset, say by warming at the surface, the moist air rises, cools and...

Weather Map Identification
2012-07-17 21:51:43

It is very important to understand what you are looking at when working with weather maps. In the image above we are looking at surface wind barbs. Surface wind barbs help us to identify which direction the wind is blowing and also the speed of the wind. If we look in the Northern Gulf of Mexico just to the south of Mississippi we see a wind barb in blue. This wind barb is from the East and it has two full wind barbs which tells us the wind is from the East at 20kts. If you look along...

Wind Shear (windshear, wind gradient) is described as difference in wind speed and direction over a short distance in the atmosphere. Wind shear is broken down into vertical and horizontal components. Horizontal wind shear is seen across weather fronts and near coastal regions. A vertical wind shear is found near the surface, or at upper levels of the atmosphere. Wind shear is a meteorological phenomenon that occurs over short distances, although it can be associated with larger scale cold...

Cirrus clouds are thin wisplike strands, sometimes accompanied by patches. Their shape and arrangement lead to their common name of "mare's tail". These clouds can be so extensive that they are virtually identical to one another and hard to tell apart. Sometimes high altitude convection produces another form of cirrus called cirrocumulus. Many cirrus clouds produce hair-like filaments made of heavy ice crystals that precipitate from them. This precipitation often indicates the difference in...
