| 摘 要： | 采用ＧＭＳ卫星红外云图的云顶黑体温度（ＴＢＢ）等值线分析方法，对１９９２年８月初在中国３个地区，不同环流背景下发生的中尺度对流系统（ＭＣＳ），即西南低涡内、西太平洋副热带高压的西北边缘和副高内部的ＭＣＳ进行了分析。结果表明，ＴＢＢ等值线分析方法能较细致地揭示ＭＣＳ的形成过程。冷云盖周围ＴＢＢ等值线疏密所反映的云顶温度梯度，对ＭＣＳ的发展有很好的指示意义。文中还给出了一个在消散阶段出现涡旋状结构的ＭＣＳ。这种涡旋结构不同与北美发现的中层中尺度气旋，它可能是凝结加热所产生的对流层高层的高压反气旋环流的反映。

| Abstract: | The blackbody temperature(TBB)of GMS satellite infrared images was analyzed for mesoscale convective systems(MCS)occuring in different regions of China in early August 1992.The evolution of three cases of MCSs,which located in the vortex of southwestern China,around the northwesternborder of the subtropical high and within the subtropical high,are given by the TBB isoline maps in denal.The results suggest that the density of the TBB isolines around the cold cloud top is a available clue to the nowcasting of MCS.One of MCS, which evolved into a vortex when it entered into the dissipatingphase,was documented in this paper. The spiriting banded structure of the dissipatingMCS reflects the upper level mesoscale high caused by the convective latent heating associated with the MCS. |
