A Study on the Surface Mesoscale Systems of the Landed Typhoon Polly (No.9216)

In the summer of 1992~1994 the Typhoon Field Science and Operational Experiment was conducted in China. In the paper the intensive observation data from the experiment were used to analyze the surface mesoscale system in the circulation of the landed Typhoon Polly (No.9216). The data were obtained from 27, 996 intensive observations (station, times) at 673 stations in 11 provinces influenced by Typhoon Polly (No. 9216). The distribution, development and evolution of the mesoscale systems are shown in detail.
