摘要/Abstract

摘要： 基于2007-2017年风云系列卫星云图资料，结合高空、地面常规观测资料，针对广西23次区域性冰雹天气过程，从主要影响系统及卫星云图云型特征方面建立3种区域性冰雹卫星云图概念模型，即华北低槽型、高原东部低槽型以及南支槽东移型。结果表明：高空槽云系的位置和所属模型类型较为关键，冰雹云团多起源于高空槽前底部；华南沿海的副热带急流云系对冰雹云团的发生发展起到重要作用，冰雹云团通常发生在副热带急流云系的北侧晴空区中；广西区域性典型冰雹云团表现为长椭圆形，上风方向边界光滑呈"V"型并沿下风方向伸出很长的卷云砧。

Abstract: On the basis of FY satellite data during 2007-2017 and conventional radiosonde and surface observations,in the light of the 23 regional hail weather processes in Guangxi,three kinds of conceptual models for regional hail against satellite imagery including the low trough type of north China,the low trough type in eastern plateau and the south branch trough type were established based on the main influence weather system and characteristics of cloud pattern inversed with satellite data.The results show that satellite imagery models play a key role in indicating the position and type of upper trough cloud,and the hail cloud cluster mostly originates from the bottom of upper trough.In addition,the subtropical jet cloud system along the South China coast also plays an important role in the occurrence and development of hail clouds which usually occur in the clear sky area on the north side of the subtropical jets.The regional hail cloud cluster in Guangxi shows up as a long oval shape with a smooth "V" shape boundary in the upper wind direction and a long anvil sticking out along the downwind.
