| 摘 要： | 用卫星云图、雷达对2008年8月7日强对流天气产生的暴雨过程跟踪观测资料,结合自动站地面降水实况和WRF模式风场资料进行短时预报分析.结果表明:扩散东移冷空气和副热带高压边缘偏南暖湿气流的共同影响下,大气层结不稳定发生强烈的强对流天气;利用卫星云图,新一代天气雷达基本反射率强度图、0.5°仰角基本速度图和风廓线产品跟踪监测,综合分析预报短时暴雨天气是有效的方法.

| Abstract: | The severe convective storm process occurred on August 7 of 2008 was analyzed by using the satellite images,radar products,the hourly rainfall data from automatic weather station and the simulated data of WRF model.The results show that the cold air and the south warm-wet air at the edge of west Pacific subtropical high resulted in atmospheric stratification being extremely unstable,so the severe convective weather occurred;it is an effective method for the nowcasting of short-time storm process using satel... |
