Abstract

Strong convective weather happened in Jiangsu and Anhui Provinces on 5 June 2009. Using the infrared data and visible data of the FY-2C satellite, the evolution and movement of the strong convective cloud can be identified and tracked. The low-level cloud and fog appeared in the morning in Jiangsu provinces made the heating inhomogeneous, which made the atmospheric stratification unstable. When the thunderstorm cloud moved close, Strong convective cloud was triggered. The strong convective cloud in Shandong peninsula at 08 BTC (Beijing Time) moved southwest and developed. After 16 BTC, the arc cloud line of the cloud evolved into deep convective cloud, which merged into another strong convective cloud originating in the middle of Anhui provinces and a stronger convective cloud formed. The area of the stronger convective cloud was even large and its shape was near circular. Then it moved south and dissipated in Zhejiang province at 24 BTC.
