摘要
统计分析最近 11 a 资料，得出热带辐合带 ( ITCZ) 各月都有，其纬度以 2 月最低，8 月最高。850 hPa 的 ITCZ 比 500 hPa 明显偏多，尤其在冬季，更是偏多一倍以上。ITCZ 对南海气候影响显著，主要表现在南海热带气旋的纬度和个数与 500 hPa ITCZ 的纬度和频率有着一致的逐月变化趋势；南海各站的降雨、相对湿度和温度与 850 hPa 的 ITCZ 关系密切。
The ITCZ appears in every month, but its latitude is the lowest in February while the hightest in August through statistical analysis of the recent data of 11a. The ITCZ of 850 hPa is more than that of 500 hPa. Especially in winter, the ITCZ of 850 hPa is one time more than that of 500 hPa. The ITCZ has obvious influence on the South China Sea's climate in two ways. One is that the latitude and number of the South China Sea's tropical cyclones have the same change tendency as those of the 500 hPa ITCZ by month. The other is that rain, relative humidity and temperature in the stations of the South China Sea have close relation with the 850 hPa ITCZ.
