全球变暖背景下对太平洋环流（1960—1999）的模拟

我们用Non—Boussinesq POP海洋模式和NECP 1000 hPa的风应力和气温场资料，模拟了1960—1999年太平洋环流，结果显示：在过去的40年，热带太平洋环流变弱了，另外，由于全球变暖，由北赤道流产生的向热带西太平洋沿岸的热输送和由南赤道流产生的向南太平洋中高纬度的热输送随着时间是减弱的，而在北半球，由北赤道流产生的向中高纬度的热输送是增加的。

Simulation of Pacific Ocean Circulations Based on Global Warming from 1960 to 1999

The Pacific Ocean circulations were simulated based on the global warming from 1960 to 1999 by using the Non-Boussinesq POP model and the data of wind stress and temperature at 1000hPa from the NCEP. The results show that the circulation in the tropical Pacific Ocean was weakening during the past 40 years. The heat transported to the tropical western Pacific Ocean coast by the north equatorial current and the heat transported to middle and high latitudes in the southern hemisphere by the south equatorial current decreased with time due to the global warming, while the heat transported to middle and high latitudes in the northern hemisphere by the north equatorial current increased with time due to the global warming.
