Fig.8 The variations of horizontal wind speed (the color shaded, Unit: m·s-1), potential temperature (contour lines, Unit: K), and the combined horizontal wind speed and vertical motion (arrow vectors, Unit: m·s-1) with height along the airflow passing through the Tianshan canyon together with the pressure difference profile between Turpan and Urumqi at 22:00 on 29 April (a), 11:00 on 30 April (b), 11:00 on 1 May (c), 11:00 on 2 May (d), 13:00 on 3 May (e), and 20:00 on 3 May (f) 2022
(Black dots indicate the height of the maximum wind speed layer exceeding 12 m·s-1 from the surface to 5 km, the same as below)
