中国大陆地区的OLR与厄尔尼诺现象
OLR OVER CHINA MAINLAND AND El Nino PHENOMENA
【摘要】 本文利用美国NOAA极轨卫星观测的1974年6月—1986年2月2.5×2.5经纬度网格区月平均的OLR资料,计算分析了中国大陆地区地—气系统射出长波辐射(OLR)的基本气候特征,给出了OLR的年、季平均值及均方差的空间分布图。并计算分析了1974—1985年期间厄尔尼诺年与反厄尔尼诺年中国大陆地区OLR的差异,进行对比分析,初步得到一些有意义的现象。
【Abstract】 In this paper, according to the monthly mean grided OLR data with 2.5 °× 2.5 °Lon. / Lat. resolution observed by the US NOAA polar-orbiting satellite during the period of from June 1974 through February 1986, the basic OLR climate features of air-earth system in China mainland, such as the spatial distributions of multi-yearly and quarterly mean values of the OLR and their RMS values, have been calculated and analysed. Meanwhile the difference of the OLR over China mainland between the El Nino years (1976, 1982 and 1983) and anti-El Nino years (1974, 1975 and 1985) were also analysed. Some interesting phenomena were revealed.
