QuikSCAT散射计矢量风统计特征及南海大风遥感分析

THE ANALYSIS ON THE STATISTICAL CHARACTER OF QUIKSCAT SCATTEROMETER WINDS AND STRONG WIND FREQUENCY USING REMOTE SENSOR DATA FROM QUIKSCAT

主要分析了QuikSCAT散射计矢量风资料的统计特征,并利用该资料分析了南海大风频数的月变化、空间分布特征以及南海各月风场的空间分布特征。结果显示QuikSCAT矢量风在南海具有可信性;利用散射计风场资料分析发现在南海主要盛行两种风,即冬季东北风和夏季西南风,东北风最大中心在巴士海峡、台湾海峡;南海中南部存在东北季风的次大中心和西南季风的极大中心。

The statistical character of QuikSCAT scatterometer winds is showed. And Monthly change and special distribution character of strong wind frequency and monthly wind fields in South China Sea is analysed. It is shown in the result that the QuikSCAT scatterometer winds can be relied upon for the South China Sea; two winds, one the wintertime northeasterly and the other summertime southwesterly. The northeaterly centers at the Bashi Strait amd Taiwam Strait and its secondary center and the maximum center of the southwesterly are in the central and southern South China Sea.
