摘要:
为分析成都地区云水资源的分布特征,利用2016年1月至2018年12月的卫星CERES数据和地面自动站降水资料,采用统计分析和对比分析的方法,得到雨日和无雨日的云水资源差别,并针对降水过程进一步分析云水资源分布与降水的关系。结果表明:冰水路径和液水路径月分布特征不一致,冰水路径从3月开始逐渐增加,9月开始减少,液水路径在春季和秋季较多,其次为冬季,夏季最少; 雨日的液水路径和冰水路径在各月份均明显高于无雨日; 高层和中高层的液水路径和冰水路径高于中低层,尤其雨日时高层和中高层的冰水路径明显高于中低层; 大部分降水过程伴随液水路径的增长和冰水路径的减少。当雨量大于2 mm时,降水中的冰水路径明显小于降水前。
Abstract:
In order to analyze the distribution characteristics of cloud water resources in Chengdu, according to satellite CERES data and ground automatic station precipitation data from January 2016 to December 2018, the differences between cloud water resources in rainy and non-rainy days were obtained by using statistical analysis and comparative analysis methods, and the relationship between the cloud water resources distribution and precipitation was analyzed further according to the precipitation process. The results showed that the distribution characteristics of the ice water path and the liquid water path were different in the year. The ice water path gradually increased from march and decreased from September. There was much more liquid water path in spring and autumn, followed by winter and least in summer. The liquid water path and ice water path in rainy days were significantly higher than that in non- rainy days. The liquid water path and ice water path in high level and mid-high level were greater than those in mid-low level, and especially in rainy days, the ice water path in high level and mid-high level were obviously greater than those in mid-low level. Most precipitation processes were accompanied by the increase of liquid water path and the decrease of ice water path. When the rainfall was greater than 2mm, the ice water path in precipitation was significantly less than that before precipitation.
