【摘要】 利用FY-2C红外云图资料,分析了2005年7月8-14日贵州全省的中尺度对流系统的活动,并对其发生的环流条件进行了诊断,还考察了FY-2C红外云图用MB曲线法[1]进行增强后的暴雨云团与8-11日暴雨落区及雨峰之间的关系。结果表明,这次暴雨过程具有明显的中尺度特征,暴雨落区及雨峰与增强显示的暴雨云团深灰区(-52℃—-58℃)发展变化迅速的一侧有较好的对应关系。更多还原

【Abstract】 By using FY-2C satellite infrared images, mesoscale convective system of Guizhou province in July 8-14, 2005 was analyzed. And a diagnostic analysis of the environmental conditions for forming mesoscale convective system was made. The relationship between the distribution of heavy rainfall in July 8-11 and the FY-2C satellite infrared images intensified in MB curve was examined. The results suggest that the mesoscale character of the heavy rainfall was obvious and the distribution of the heavy rainfall corresponded with the developing rapidly deep gray area(-52℃— -58℃) of the FY-2C satellite infrared images intensified.更多还原
