图7 WRF模式模拟的2022年7月扰动虚温（填色，单位：K）和扰动纬向风速（黑线，单位：m·s-1）沿图2中红色线段的垂直剖面 （扰动虚温为剖面内相对于高度平均值的偏差，扰动纬向风速为相对于日平均值的偏差；红色箭头为局地环流方向，灰色区域为地形）

Fig.7 Cross section profile of the perturbation virtual temperature (the color shaded, Unit: K) and perturbation zonal wind speed (black lines, Unit: m·s-1) simulated by WRF model along red line in fig.2 in July 2022 (Perturbation virtual temperature is deviation from the mean height within the profile, perturbation zonal wind speed is deviation from the daily mean zonal wind speed; the red arrows indicate the direction of the mountain-plain circulation, the grey area represents the terrain)
