Abstract:
Hazard wind weathers in Jiangxi are discussed with conventional data, disaster information and radar data, it is found that there are three major weather types of disastrous winds, i.e. (1) thunderstorm gale weather accompanied by the radar echo systems with the echo band of squall line and super cell etc., at the same time, also accompanied by strong lightning, severe precipitation, hailstone, tornado and other hazard weathers; (2) hybridgale weather, accompanied by thunderstorm echo band of cold front and cold air gale, presents the characteristics of thunderstorm gale and cold air gale activities; (3) disastrous wind weather without rainfall, caused by the joint action of downdraft of thunderstorm triggering, downpropagation of aloft kinetic energy as well as pressure gradient wind, and it is not accompanied by rainfall, lightning and other weather phenomenon.
