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.
