| 摘 要： | 本文利用TOPEX／POSEIDON高度计资料，计算了中国近海渤海、两巴海峡、黄海、东海中部和南海北部等五个典型区域海平面高度异常特征指数，分析了各海区特征指数的振幅变化规律及周期，并用这些指数与海平面风场及温度场分别进行了相关分析。结果表明：我国近海海平面高度异常除黄海外各海区都具有显著周期变化。异常指数与风速正相关主要分布在西太平洋中低纬海域，负相关区域主要位于中亚至我国大陆西部和中太平洋近赤道海域，与温度场正相关区分别位于非洲大陆南部、澳洲大陆南部和南美大陆中南部，负值相关区主要位于北印度洋和东太平洋海域。与温度相关场分布表明中国近海海平面高度异常与ENSO现象有关。

| Abstract: | Used the (Topex/Poseidon) sea surface height data, the character inde x of SSHA near the China Seas is calculated. The five calculated area include the BOHAI Se a (Area A), the BASHI Strait and BALINTANG Strait (Area B), the middle HUANGHAI Sea (Area C) and the East Sea (Area D), and the northern SOUTH China Sea (Area E). T he index shows all the SSHA have months cycle except HUANGHAI sea (Area C). On the base of this, the correlation analysis is done between the SSHA near the China S eas and SST and the wind of the 995hPa (taken from the NCAR/NCEP). The results show that the main positive correlation area of wind on the low latitude of the west Pacif ic. The negative related area is in the South Asia and the northern India ocean. The SST have three observed correlation area to the SSHA. They are the southern Africa mainla nd, the South America mainland and the Ocean near the Australia. The negative area in th e eastern Pacific, which shows the SSHA is related to ENSO. |
