中文摘要: 用1971~2002年的气象资料,分析了不同路径台风影响上海时风速风向的分布特征。登陆台风影响时,上海南部地区风速最大,主导风向是偏东风;近海北上台风影响时,上海东部的风速最大,风向以东北偏北为主。城市的发展使台风影响上海时的风速明显减小。
Abstract:Based on the meteorological data of more than thirty years, the distribution of wind speed and direction are analyzed when various routes typhoons influencing Shanghai. When a landing typhoon influencing Shanghai, wind speed of the southern area is the largest, dominant wind direction is bias E. While the influencing typhoon is offshore and moving north, wind speed of eastern area is the largest, NNE is the dominant wind direction. The development of the city makes wind speed clearly reduce during the period of typhoon influencing Shanghai.
