图5 30日00时至31日09时200 m高度上风速（单位：m·s-1）的填色图，黑色圆环表示200 m高度上最大风速半径，矢量箭头为200~850 hPa环境场垂直风切变，黑色圆点代表TSV

Fig.5 Wind speed (unit： m·s-1) at 200 m height from 00:00 on the 30th to 09:00 on the 31st，with the black circle indicating the radius of the maximum wind speed at 200 m height and the vector arrows showing the vertical wind shear in the ambient field between 200 hPa and 850 hPa
