利用具有较高时空分辨率与很好时空完整性的11年（1996-2007年，无2004年16—8月静止卫星数字红外云图和TBB资料，给出了华南及邻近海域夏季深对流活动气候分布特征，并同文献中给出的雷暴日分布和闪电分布进行了对比分析。结果表明，华南及邻近海域夏季深对流活动有5个活跃中心，其月变化特征与大尺度环流背景密切相关。6月华南陆地区域深对流活动较活跃，7、8月南海海域深对流活动较活跃。华南及邻近海域深对流活动具有间歇性发展特征，其周期大约为3～5候，但华南海岸线附近为海陆过渡区域，深对流活动持续比较活跃且间歇性特征不突出；深对流活动旬与候变化特征表明华南陆地区域和南海海域深对流活动呈现反相关变化趋势。深对流活动的日变化特征显示该区域陆地与海洋、山地与盆地的热力差异所导致的海陆风环流与山谷风环流使得华南海岸线附近区域的深对流活动具有午后向陆地传播、午夜后向海洋传播的特征，山地与盆地的深对流活动具有显著的午夜后向盆地传播的特征。深对流活动日变化特征还表明该区域不仅具有一般热对流、海洋深对流和双峰型深对流等多种类型对流活动，且两广海岸线邻近区域具有持续时间长、日变化较不显著的海岸线深对流和其它天气系统触发和维持的深对流。

英文摘要：

Due to the higher temporal and spatial resolution and the better integrality of long-term satellite infrared （IR） temperature of black body （TBB） data, a climatology of deep convection during summer over South China and adjacent seas is presented in this paper based on the 1-hourly IR TBB data during June--August of 1996--2007 （except 2004）. The results show that the climatological characteristics of deep convection denoted by TBB ≤ -52 ℃ over South China and adjacent seas are basically consistent with those previous statistical studies based on the surface thunderstorm observations and the low-orbit satellite lightning observations. The monthly variations, ten-day variations, five-day variations and diurnal variations of deep convection over South China and adjacent seas are focused on in this paper. The results show that there are 5 active deep-convection areas in South China and adjacent seas during the period of June--August. The monthly variations of the deep convection over South China and adjacent seas are closely associated with the large-scale atmospheric circulation. The deep convection over the land in South China is more active in June, while that over South China Sea is more active in July and August. The development of the deep convection over South China and adjacent seas has a characteristic of intermittence, and its period is about 3-5 five-day. However, the deep convection over the neighboring areas of coastline in South China remains more active during summer, and has no obvious intermittence characteristic. The ten-day and five-day variations of deep convection show that there are different variations of deep convection over different areas in South China and adjacent seas. The tendency of the deep convection over the land in South China is negatively correlated with that over South China Sea. The diurnal variations of the deep convection over South China and adjacent seas show that the sea-land breeze caused by the thermal difference between land and sea and the mountain-valle
