中文摘要:
      本文用月平均资料详细地计算了强厄尔尼诺时期(1982年8月—1983年7月)西太平洋及其邻近地区的大气加热场。结果表明:(1)西太平洋、太平洋中部赤道及其热带全年是一个范围大、强度强的热源区,而上述热源区北、南两侧的副热带则为大范围的冷源区。我国南海也有一个较强的热源区。赤道热源带的南移和加强是厄尔尼诺时期的一个重要特征;(2)各月大气加热场的分布特征可分为冬春和夏秋两类;(3)总加热率的月际变化明显,且有2次显著的增热过程。
英文摘要:
      Using the monthly climatic data, the atmospheric heating field over the west Pacific and its surrouding sea area in the strong El Nino period (from August 1982 to July 1983) is computed in detail. The main results are as follows: (1)The equatorial and tropical sea area in west Pacific and in the middle of Pacific is a heat source area with strong intensity and large range through the year. But the subtropical sea area at both southern and northern side of equator which neighbours with this heat source is a large range of cold source. China South Sea has also a stronger area of heat source. The Southword movement and intensification of equtorial heat source belt are important characteristics in EI Nino Period.(2)Distribution characteristics of atmospheric heating field can be classified into two types: the Winter-Spring and the Summer-Autumm types. (3)The inter-monthly variation of total atmospheric heating rate is very evident and there are two notable heat increasing processes.
