Seasonal structure characteristics of day and night cloud in the East China Sea Zone
摘要
Abstract
That the spatial and temporal distribution characteristics of cloud cover and cloud height in the East China Sea Zone in each season or day and night is analyzed using the 2B-GEOPROF and 2B-GROPROF-Lidar data of CloudSat from 2007 to 2010.The results show that the cloud cover and cloud height has evident seasonal and regional differences,with a more quantity of total cloud cover in spring and summer and a less in autumn and winter.While,there is a more low-level cloud cover in winter and a less in summer..It is cloudy all the year round from Taiwan island and east of Taiwan island to 123° E,the yearly average total cloud cover is more than 65%,and the yearly average low-level cloud cover is more than 45%.The cloud cover has obvious differences between day and night.The yearly average total cloud cover is more at 18 UTC than at 6 UTC in most area.Above the sea,the yearly average total cloud cover is above 50%~60% at 6 UTC,and 55% ~70% at 18 UTC.Average minimum cloud base height and average maximum cloud top height are highest in summer and lowest in winter.At 6 UTC,the area with low values of cloud height is in the region from Taiwan Island to its north-east sea area,and the area with high values is in the region of the Ryukyu Islands.But at 18 UTC,the cloud rise in coastal area,and bring down on the sea,and the new area with low values of cloud height is at the north of the Ryukyu Islands.关键词
