An investigation into the vertical structures of low‐altitude atmosphere over the Central Taklimakan Desert in summer

open access: yesAtmospheric Science Letters, Volume 22, Issue 9, September 2021., 2021
There is an obvious diurnal transition in lower layers near the ground over the Central Taklimakan Desert. A clear presence of the superadiabatic layer is obvious in the daytime, and an apparent inversion layer forms in the nighttime. Abstract In this study, 1‐month continuous radiosonde observational data were applied to present the low‐altitude ...
