Abstract
Using the observation data of Beijing automatic station and the conventional and unconventional observation data of Haidian National Meteorological Observatory in Beijing,from the perspective of forecasting and warning service of regional meteorological stations, a severe con-vective hail weather on June 10,2016 was analyzed.The results showed that the haze strong convection process was triggered by the combination of high-altitude and low-vortex,low trough and ground cold front,which was caused by the ground convergence lines and high temperature and high humidity heat instability.A comprehensive analysis of the distribution of ground conventional elements in city's range found that the thermal and dynamical effects of complex underlying surfaces provided a series of triggering mechanisms for the enhancement of convective development. For the emergence of high temperature and high humidity,convergence line, convergent vortex and other features, should cause great concern. Comprehensive air pressure,temperature,wind speed,horizontal visibility and other local routine observation of changes in factors,for the system had not affected the local,the pressure began to decline 30 min before the rain began to decline was the first recognized.Distribution changes of horizontal wind field and atmospheric refractive index structure constant in wind profile radar compared to conventional ground automatic station data for the identification and prediction of the strong convection weather characteristics was more significant.关键词
