摘要:
利用华南地区14个站点2010年1月1日至2015年12月31日六年逐日的L波段探空资料，对华南地区对流层顶、边界层顶的时空分布特征及其高度的变化特征进行分析。结果表明，华南地区平均对流层顶高度5月最高，8月最低，对流层顶的变化与夏季风爆发的时间节点有较好的对应；平均边界层顶高度3月最高，8月最低，沿海站点与内陆站点边界层顶高度变化规律明显不同；华南地区四季的平均边界层高度的空间分布与对流层顶高度的空间分布反相，西沙上空与广西西北部两块区域始终存在极值中心。
Abstract:
Using the L-band radiosonde data of 14 stations in South China from January 1, 2010 to December 31, 2015, the temporal and spatial distribution characteristics and height variation characteristics of tropopause and atmospheric boundary layer(ABL) over South China were analyzed. The results showed that (1) the mean tropopause height of South China was the highest in May and the lowest in August, and the tropopause apex change corresponded well with the time node of summer monsoon onset.(2)The average height of the boundary apex was the highest in March and the lowest in August; the variation of the apex height between coastal and inland stations was obviously different. (3) The spatial distribution of the mean boundary layer height in the four seasons in South China was opposite to that of the tropopause height. There were always extreme centers over Xisha and Northwest Guangxi.
