摘要
利用气象单收站和新一代天气雷达资料对2006年4月23日发生在兵团农六师境内一次冰雹天气的成因进行分析,结果表明:当日北疆地区的气压分布有利于冷空气入侵,充足的水汽、下垫面的快速增温以及局地的气流辐合为对流云的形成提供了热力和动力条件,雷达回波径向速度场中的垂直风切变也有利于强对流云的产生和维持。这些结论对今后的强对流天气预报具有一定的指导意义。
The cause of formation of a hailstorm weather which was found in the 6th farming division in Xinjiang production and construction corp.in April 23th 2006 was analyzed by means of the data of meteorological satellite ground station and Doppler radar,the results showed that pressure distribution in northern Xinjiang made for inbreak of cold air;sufficient water vapor,rapid heating of underlying surface and local air current convergence offered thermal and dynamic conditions to the formation of convectional cloud;wind shear in the radial velocity field of radar echo was in favor of the maintenance of cloud;these conclusions have some guidance for the strong convectional weather forecasting in the future.
