摘要：This paper reports the post-disaster results due to Typhoon Megi. The survey was conducted by a joint survey team of Shanghai Typhoon Institute in 14 December 2016, with the support of Wenzhou Meteorological Bureau and some meteorological departments in disaster areas. The survey results show that Typhoon Megi brought torrential rain and heavy rainstorm to the southern of Wenzhou City. The precipitation characters of Typhoon Megi are strong intensity, high accumulation, long duration and broken historical record. Typhoon winds affected wide,with large peripheral wind. According to the needs of defense and emergency rescue of Typhoon Megi,Wenzhou meteorological departments made every effort, including closely monitor, strengthening consultation, roll forecast, timely warning, active reporting, and targeted service. In order to provide scientific reference for government decision, the service of weather protection and disaster relief were done well. The results of typhoon forecast shows as follows.(1) The track, landing location and time of typhoon forecast were basically consistent with the actual situation.(2) The wind forecast was close to the actual.(3) The forecasted area precipitation was slightly lower, and the extreme value of process precipitation was too low. While the prediction of Dongtou Island Station was too high, this investigation shows that we are still insufficient in forecasting precipitation grades of typhoons breaking historical records, especially for precipitation quantification and meticulous prediction. In this case, more attention should be paid as below. 1) Effect of topography on precipitation enhancement. 2) Summary of similar cases. 3) Improve the defense ability and residents’ awareness of risk. 4)Combine modem methods of early warning information with traditional methods. 5) Quantitative, fixed-pointed and precision forecast. 6) Rapid access of referent information to forecasters, 7) Modern monitoring technology(3 S, unmanned aerial vehicle) should be used for disaster investigati
