【摘要】 根据TOGA—COARE强化观测资料分析西太平洋暖地区低层大气的气象学特征。讨论北半球冬季(11月-2月)该区域海面风和温度的特征,ITCZ及其有中尺度动力学特征的赤道大气涡(Eddy)的演变特征,对流混合边界层大气和低层正压大气层特征,以及云形态及降水特征等。指出,对于赤道大气,把正压大气层顶取为700hPa是合适的。更多还原

【Abstract】 In this paper, discussed and analysed are the meteorological features of the low-level atmosphere in the region of tropical western Pacific warm pool based on the intensive observation data of TOGA -COARE. The basic features of the surface temprature and wind, the evolution features of the equatorial atmospheric eddy and ITCZ, the features of convectively mixing boundary layer and low-level barotropic atmosphere, cloud mophology and the precipitation features in this region during the Northern Hemisphere winter are discussed in this paper. We point out that it is appropriace to consider the atmosphere below 700 hPa barotropic.更多还原
