| 摘 要： | 利用2011—2020年ERA5再分析降水资料、CERES云物理参数产品，分析新疆云参数的时空变化分布特征，归纳总结云物理参数与降水的相关性，结果表明：1）云水路径（冰相）值、云粒子有效半径（冰相）、云光学厚度与降水量的空间分布一致，均为山区最大，北疆次之，南疆最小。2）夏季（6—8月）在南、北疆、山区云水路径（液、冰相）、云顶（底）温度、云光学厚度与降水量呈同位相变化；云粒子有效半径（液、冰相）、云顶气压与降水量呈反位相变化。3）夏季（6—8月）北疆、山区的云水路径（液、冰相）值、云顶（底）温度、云光学厚度，南疆云光学厚度与降水量呈正相关；北疆云粒子有效半径（冰相），南疆云粒子有效半径（液相）、云顶气压，山区云粒子有效半径（液、冰相）、云顶气压与降水量呈负相关。

| Abstract: | Using the 2011-2020 ERA5 reanalysis precipitation data and CERES cloud parameters, the spatial and temporal distribution characteristics of cloud parameters in Xinjiang ,the correlation between cloud physical parameters and precipitation are discussed, and the conclusions are as follows:cloud water path (ice phase),cloud effective radius(ice phase), cloud optical thickness are similar to the precipitation in spatial distribution, of which the values are the largest in mountainous area and the least in southern Xinjiang.The changing trends of cloud water path(liquid and ice phase),cloud base temperature,cloud top temperature,cloud optical thickness are similar to that of the precipitation in summer(from June to August) in mountainous area, northern and southern Xinjiang,while the changing trends of cloud effective radius (liquid and ice phase),cloud top pressure are reverse to that of the precipitation.The correlations in northern Xinjiang and mountainous areas in Xinjiang are positive between cloud water path(liquid and ice phase),cloud base temperature,cloud top temperature,cloud optical thickness and precipitation in summer(from June to August),as is the correlation in southern Xinjiang between cloud optical thickness and precipitation.The correlation in northern Xinjiang is negative between cloud effective radius (ice phase),as are the correlations in southern Xinjiang between cloud effective radius(liquid phase), cloud top pressure and precipitation and that in mountainous areas between cloud effective radius (liquid and ice phase), cloud top pressure and precipitation. |
