1986年冬季热带西太平洋区域性大气总能量收支

REGINAL BUDGET OF ENERGY IN THE TROPICAL WESTERN PACIFIC DURING THE WINTER OF 1986

中文摘要:

      本文采用中美海-气合作考察第一次航程(1986.1.9-15,2.1-14)和若干站点的海洋气象资料,计算了热带西太平洋不同区域的大气湿静力能量的水平输送和局地变化、大气非绝热加热诸分量以及各区域海面与大气的热交换项.分析指出,在考察期间热带西太平洋上空,西部区是大气能量水平输送的能汇区,而东、中部区则反之.同时,热带西太平洋上空大气和海洋下垫面是个热源区,尤以西部区最为明显.由此可知,热带西太平洋大气能量收支具有明显的区域性差异,其西部区是较强的大气和海洋下垫面的热源区域,是热量、能量积存最多的地区.

英文摘要:

      Based on the marine and meteorological data collected by the vessel "xiang-yang-hong No.14,China" for the first PRC-US joint investigation on ocean and atmosphere over the West Pacific Ocean and other observations from meteorological stations,some physical characteristics,horizontal transfer,local change terms of moist static energy,atmospheric diabatic terms and interchange terms of air-sea,on West Tropical Pacific,which has been divided into three parts named east,middle and west areas,respectively,have been calculated in this paper.It has been point out that there was a energy sink of the horizontal transfer in the atmosphere over the west area,but other areas are invertion.Meantime,the heat sources of atmosphere and sea surface appear on all three areas.Among them,the west area is shown as an intenser heat source.By mentioned above,the distribution of energy budget on the West Tropical Pacific is not even.?Jspecially,the west area is a stronger storage-region of heat and energy during the expedition period.
