西太平洋热带地区大气能量收支分析——中美西太平洋海-气合作考察观测事实之二

依据1986年2月8—14日中美西太平洋海气合作考察资料,计算了西太平洋热带海域(140—160°E,18°N—14°S)内的大气能量收支。结果表明,该区域的能量是由外界向区域内输送的。在东、南、西、西北四个边界积上以能量输到为主,只有在东北边界上,以输出为主。该区内的能量输送是以平均输送为主,扰动输送的数量级较小。考察期间,该区域内大气有明显的增温现象。

A survey of the atmospheric energy budget over the West Tropical Pacific

Based on the data of the investigation through the 8th to 14th of February, 1986, the atmospheric energy budget in a polygon area of the West Pacific Ocean (140-160°E, 18°S-14°N) has been calculated. It is shown that the total energy budget transports from outside toward inside of the polygon area. Among the all boundaries, however, the energy transfer only in the north- eastern boundary could display in opposite phase. Meanwhile, the major energy transfer would be by mean transfer rather than by disturbance. This study has also point out that there was the obvious warming-atmosphere phenomenon over the area during the investigation periods
