MJO与热带风场、海温日变化的关系
Relationship between MJO and tropical wind diurnal cycle with SST diurnal warming
摘要
Abstract
The relationship between MJO and wind diurnal cycle and sea surface temperature (SST) diurnal warming are analyzed by using CCMP wind field and NOAA surface solar flux.The results are as follows:Wind diurnal cycle and SST diurnal warming are significantly different when MJO in different phases.In summer,when MJO is in phases 1 to 4,the equatorial Indian ocean has strong precipitation and weak solar radiation,meridional wind (v) diurnal cycle becomes weak.V diurnal cycle in the Indian ocean becomes strong when MJO in phases 5-8.The meridional diurnal cycle in the western Pacific has an opposite performance with that in the Indian ocean.The effect of MJO on SST diurnal warming is stronger in winter than that in summer.The Dynamo observation data proves that the main factor causing sst diurnal warming in an empirical formula in the equatorial region is the changes of wind.The effect of radiation is far less than that of wind.关键词
