Abstract:Based on the hazardous weather report, disaster telegraph data and NCEP 1°×1° reanalysis data from 175 stations in Beijing, Tianjin and Hebei from May to September during 2001-2008， the statistical analyses are used to explore the temporal spatial distribution and synoptic characteristics of severe convective weather there. The analysis results indicate that：(1) In this period， the wind force always reaches 7-8 scales with prevailing northerly and westerly winds， the south central and northwest of Hebei area, and Beijing and Tianjin have strong winds； Larger hails often occur in Beijing, Tianjin and the northwest and north of Hebei； Within 10-60 minutes， the precipitation easily reaches 20-25 mm， while during 130-180 minutes， the precipitation can reach 50-100 mm. (2) During 2001-2008， the winds often occur in May and June， the hails occur in June， but the short time rainstorms occur in July and August； (3) Except for short time rainstorms， winds and hails approach to the Taihang and Yinshan Mountains and reduce gradually from northwest to southeast. The severe convective weather has the obvious characteristics of daily variation， a majority of severe convective weathers (62%) occur in the afternoon and early evening (14:00-20:00 BT). (4) There are three main weather circulations： the cold vortex pattern in which mainly appear hails accompanied by gales or short time rainstorms， the cold trough pattern in which mainly appear strong winds with short time rainstorm， and the trough and subtropical anticyclone pattern which always brings short time rainstorms. A weather conceptual model which is established through the typical case has a good significance for weather forecasting.
