| 摘 要： | 热带辐合带(ITCZ)是大气环流的重要成员之一,它的活动与变化不仅对于热带天气,而且对于中纬度地区的旱涝以及全球大气环流的变化都有重大影响。ITCZ最初着重于用风场资料来研究,但由于海洋上测站稀少,往往难于精确地确定。但在这种热带辐合区内一般都伴有对流云雨的发展,所以卫星成为观测ITCZ的很好工具。利用早期卫星测得的云反射的亮度或平均云量研究ITCZ已有不少的工作。但或由于资料年代短,或只局限于某一地区,至今尚无全球范围的比较详细和有代表性

| Abstract: | The outgoing longwave radiation (OLR) data derived from the NOAA polar orbiting satellites during the period June 1974 through May 1984 have been used to construct the climatic charts of ITCZ all over the globe.The monthly variation of the ITCZ over different parts of the tropical continents and oceans and it's climatic characteristics are researched.Especially it is revealed that there is annual oscillation of the double ITCZ over the Pacific Ocean. |
