| 摘 要： | 利用NCEP1°×1°的再分析资料，用大尺度水汽通量流函数和速度势以及水汽收支对台风“麦莎”在移动过程中水汽输送流函数和速度势进行了分析。结果表明：台风“麦沙”在北上过程中，主要有2支水汽通道，一支是从太平洋开始向西经赤道到达印度洋，在索马里转向，经过孟家加拉湾呈西南气流向西北方向输送；另一支来自副高南侧偏东气流。计算分析还表明，用无辐散风流场来定台风中心要比用总的流场更精确。

| Abstract: | Using the NCEP reanalysis data,In this paper,it is indicated that the vapor flux plays a very important role in the moving of typhoon Masta through the calculation of stream function,velocity potential and vapor budget in the large-scale.It is showed that there are two vapor channels.One comes from the Pacific to the equator and arrives in Indian Ocean.Turning at Somalia,through the Bengal Bay,it transports southwesterly to the northwest direction.Another comes from the south side of the subtropical high an... |
