北太平洋中纬度地区海气热交换场的EOF分析

EOF ANALYSIS OF AIR-SEA HEAT EXCHANGES IN MIDDLE LATITUDES OVER THE NORTH PACIFIC

中文摘要:

      众所周知海洋与大气之间的热交换对大气环流的形成和变化有着童要的作用.本文根据Clark计算的资料对20°N以北北太平洋中纬度地区的蒸发潜热、净长波辐射和感热输送进行了EOF分析,以讨论其季节变化特征.资料范围在22.5-52.5°N,122.5°E-112.5°W,共128个网格点,格距5×5度,1950-1979年.

英文摘要:

      An empirical orthogonal function analysis is performea on 30-year monthly means of latent, sensible heat fluxes and back radiation is middle latitudes over the North Pacific,The results show that the first three eigeavectyrs of them are three similar patterns and their corresponding time coefficient series have almost the same variation tendencies.
