摘要
云是大气垂直运动和湿状况的综合体现,云量的变化从另一个侧面反映了气候变化。气候模式中云参数的任何变化,都可能对全球气候产生重大影响。本文主要总结了近几十年有关我国云量的时空变化及其与降水关系的研究成果,同时也指出了目前多种云资料的优缺点。此外提出应充分利用现有的资料来研究云量最多、云层最厚的西南地区云的特征及其变化。
Cloud is a comprehensive reflection of atmospheric vertical motion and the wet conditions,and changes in cloud amount also represent the climate change in another aspect.And any changes of cloud parameters in climate models may has a significant impact on the global climate.The main study results on cloud in recent decades are summarized,which include the temporal and spatial distribution of cloudiness,the relationship between cloud and precipitation,the difference among the several cloud datasets.On the basis of above,it is suggested that the character of cloud and its variations in the Southwest China,Characterized by maximum cloud amount and the thickest cloud area within inland China,should be much studied.
