Satellite Imagery monitoring extreme weather including Tornado Alley
Since the 1970’s, the launch of satellites have significantly enhanced metoeorology and forecasting around the globe. Satellites vary from geostationary satellites that remain fixed over a location above the earth to polar orbiting which circle abut the earth scanning as they traverse the globe. The types of images visible (picture of clouds from space) to infrared (thermal imagery based on temperature gradients) and water vapour imagery. A combination of all these images are used to monitor weather systems and significant events such as tropical cyclones and tornado outbreaks. Modern technology and the use of GPS standards enable satellite data to be overlayed with other data.
