Abstract:
Using the Yingkou Doppler weather radar data, a preliminary analysis is made on the tornado process which occurred in the six townships of Yingkou Sou theast at about 16:00 on 10 August 2005. the main weather situation is a trough at hight altitude led by a northeast vor tex. The dry and cold air along the contour line and the wet and warm air produc ed stratification with covective instability. The south branch of jet and the so uthwest jet at low altitude as well as the northwest wind at high altitude gener ated a strong vertical wind shear, which is favorable for the generation of torn ado weather. This super cell is a low centroid convective system, of which the r eflectivity of radar echo is above 45 dBz. The severe tornado is accompanied wit h heavy rain, but without hail. The analysis indicates that this tornado is main ly a mesocyclone displayed on the velocity map. This case illustrates that the China new generation Doppler weather radar has the capability to detect tornado es.
