摘要
Abstract
[Objective] The Doppler radar data about a super monomer hailstorms in the northeastern Qinghai-Tibet Plateau in the Zhongshan Airport in the Lanzhou City on September 6, 2010 was studied. [Method] By dint of routine data and radar data, the low vortex shear line type and the super monomer hailstorm around the Zhongshan airport in the Lanzhou City on September 6, 2010were expounded. Basic product and secondary product of Doppler radar were used in this process to reflect the characteristics of strong convection weather. Some characteris tics of this process shall be explored. [Result] A small gush of cold air from the cold vortex of 500 hPa in the middle and high layer provided impacts. The warm shear line provided water vapor and energy in the 700 hPa. There was strong convective weather in the upper air. Such 10 minutes of hailstorm was rarely seen in the drought land in the northwest. The characteristics of the strong convection were distinct and typical. The front showed no echo form. However, it can not be reflected in "strong wedge" in another form. In this process, characteristics of BWER and middle scale cyclone were distinct. And this was a typical hailstorm process caused by super monomer. [ Conclusion ] The study provided some helpful references for the forecast of strong convection weather in the Zhongshan airport in Lanzhou City.关键词
