What is Storm: Definition and 73 Discussions

A storm is any disturbed state of an environment or in an astronomical body's atmosphere especially affecting its surface, and strongly implying severe weather. It may be marked by significant disruptions to normal conditions such as strong wind, tornadoes, hail, thunder and lightning (a thunderstorm), heavy precipitation (snowstorm, rainstorm), heavy freezing rain (ice storm), strong winds (tropical cyclone, windstorm), or wind transporting some substance through the atmosphere as in a dust storm, blizzard, sandstorm, etc.
Storms have the potential to harm lives and property via storm surge, heavy rain or snow causing flooding or road impassibility, lightning, wildfires, and vertical wind shear. Systems with significant rainfall and duration help alleviate drought in places they move through. Heavy snowfall can allow special recreational activities to take place which would not be possible otherwise, such as skiing and snowmobiling.
The English word comes from Proto-Germanic *sturmaz meaning "noise, tumult".Storms are created when a center of low pressure develops with the system of high pressure surrounding it. This combination of opposing forces can create winds and result in the formation of storm clouds such as cumulonimbus. Small localized areas of low pressure can form from hot air rising off hot ground, resulting in smaller disturbances such as dust devils and whirlwinds.

    Did a Big Wind Storm Destroy a Family's Home Last Night in the NW?

    Will Tropical Storm Gamma Follow Hurricane Wilma's Path to Florida?

    As a tropical depression, it was not expected to be a threat to the US. Well Nature had other ideas. Gamma may reach hurricane strength if it passes into the Gulf of Mexico, and it could follow Wilma's track to S. Florida. http://www.wunderground.com/tropical/tracking/at200527.html...

    Why was the storm surge in Biloxi, Mississippi so much higher than expected?

    With the understanding that I'm taking no credit for this, rather, I was simply regurgitating what had been seen on TV - science shows on DSC, NGC, etc - I predicted a 50ft storm surge around Biloxi Miss. AFAIK this was not predicted by the experts but I can hardly understand why. And it's...
