Mysteries of Thunderstorms
Satellite imaging is now
helping atmospheric
scientists link the amount
of charged ice in clouds to
lightning activity. Ice
particles in thunderstorms
can help increase

Storm Warnings Right On Track
Meteorologists no longer
have to unnecessarily alarm
an entire county with a
storm warning. Using a
computer program that
reflects an increase in the
understanding of how storms

Predicting the Weather: Getting It Right!
The U.S. experiences more
severe storms than any other
country in the world. Recent
improvements in forecasting
technology -- especially in
computer simulations have br ... > full story
Lightning: Fact or Fiction?
To study lightning,
scientists use rockets
connected to the ground by
wires. They fire the rockets
into clouds, triggering
electrical discharges, and
storing their power. They

Meteorologists' New Scale Will Help in Emergency Planning
Those who live in the Northeaster United States will be able to plan ahead for major storms thanks to a new ranking scale that predicts not only how many inches of snow will fall, but also how long ... > more -
Meteorologists Describe Little-Known Giant Windstorms
Derechos are elongated, straight-lined windstorms that often have bands of rapidly moving thunderstorms associated with it. These little-known atmospheric phenomena often stretch for hundred of miles ... > more -
Improving Accuracy Of Hurricane Forecasts
Meteorologists have found a new discovery may boost the accuracy of the forecasts. The surprising factor is dust, researchers have found that years where there was a lot of dust, there were less ... > more -
Veterinarians Show Consoling Dogs Does Not Relieve Their Panic
A new study shows that dogs can get very upset during thunderstorms, whether or not their owner holds them. The study measured the stress hormone cortisol to be up to three times normal levels while ... > more -
Meteorologists, Atmospheric Scientists Fly Through Storms to Gather Data
During hurricane season, scientists fly aboard NOAA aircraft to pinpoint the precise path of the eye of a storm, and to take data to send back to the National Hurricane Center. The planes are now ... > more -
Meteorologists, Atmospheric Scientists Perfect Next-Generation Weather Simulation
Three category-5 hurricanes hit the U.S. in 2005 -- a record. Weather forecasters now hope to reduce the loss of lives caused by hurricanes with better computer modeling. With more precise ... > more -
Meteorologists Tap Into Public For Help Tracking Storms
By recording the shape of snowflakes seen under a magnifying glass and submitting the information to a NASA Web site, the public can contribute to a global snow-tracking network. Different types of ... > more -
Cool Pacific Waters May Not Affect Upcoming Hurricane Season
Like their more dramatic cousins El Niños, La Niñas -- the periodic cooling of ocean waters -- can have a dramatic impact on hurricanes, meteorologists say. The current La Niña, ... > more -
Using Radar, Meteorologists See Increase in Hurricane-Made Tornadoes
Tornadoes can form when hurricanes make landfall, as their winds at ground level slow down, while the winds near the top keep their momentum. Data from 2004 show this tendency seems to have ... > more -
Meteorologists Invent Better Way To Monitor Hurricane Strength
Meteorologists have developed a new method for analyzing hurricane strength. A series of mathematical formulas transform data from Doppler radars into a 3-D picture of storm intensity every 6 ... > more
