Storm spotting – The observation of severe weather by individuals trained in weather and reporting. Spotters can be stationary or mobile. Storm Data (SD) – A National Climatic Data Center (NCDC) publication beginning in 1959 detailing quality controlled tornado and other severe weather summaries as the official NOAA record of such events.
Outflow boundary on radar with radial velocity and frontal boundary drawn in.. An outflow boundary, also known as a gust front, is a storm-scale or mesoscale boundary separating thunderstorm-cooled air from the surrounding air; similar in effect to a cold front, with passage marked by a wind shift and usually a drop in temperature and a related pressure jump.
Radar image animation of an outflow boundary of a storm approaching Tulsa, Oklahoma. The outflow boundary's weak echo moves left-to-right and passes overhead of the Doppler radar station. The outflow produces a gust front that moves ahead of the main thunderstorm. Outflow, in meteorology, is air that flows outwards from a storm system.
The 1998 Comfrey–St. Peter tornado outbreak was an unseasonably-strong tornado outbreak which affected the Upper Midwest region of the United States on March 29, 1998. A strong area of low pressure combined with a warm front and favorable upper-level dynamics to produce 16 tornadoes across the region—14 in Minnesota and two in Wisconsin.
In the United States and a few other countries, Doppler capable weather radar stations are used. These devices are capable of measuring the radial velocity, including radial direction (towards or away from the radar) of the winds in a storm, and so can spot evidence of rotation in storms from more than a hundred miles (160 km) away. A supercell ...
The pier built by the U.S. military to bring aid to Gaza has been removed due to weather to protect it, and the U.S. is considering not re-installing it unless the aid begins flowing out into the ...
Weather modification is the act of intentionally manipulating or altering the weather.The most common form of weather modification is cloud seeding, which increases rainfall or snowfall, usually for the purpose of increasing the local water supply. [1]
WSOC-TV anchor and reporter John Paul is leaving the station this week after seven years.. Paul announced his pending departure on Facebook. “I have an amazing opportunity to work at 6abc Action ...
