图10 陕西各区域暖型雷暴大风500 hPa频率大于15%的环流型风场（风矢，单位：m·s-1）、垂直速度（填色，单位：Pa·s-1）和相对湿度（等值线，单位：%）合成场沿过程平均发生位置的垂直剖面 （灰色阴影为地形，五角星为过程平均发生位置，空心圆为风速小于2 m·s-1）

Fig.10 The vertical profiles of the composite fields of wind field (wind vectors, Unit: m·s-1), vertical velocity (the color shaded, Unit: Pa·s-1) and relative humidity (isolines, Unit: %) along the average location of warm type thunderstorm gales with 500 hPa circulation type frequency greater than 15% in each region of Shaanxi Province Grey shaded is for topography, the five-pointed star is the average occurrence position of the processes, the hollow circle indicates the wind speed is less than 2 m·s-1
