The Inversion Capped ABL of the Winter Monsoon over the East China Sea during AMTEX

Abstract

The observed thermodynamic structure of the winter monsoon ABL during the air-mass transformation experiment is studied with a simple steady-state inversion model, taking into account the effects of large-scale subsidence, turbulent mixing, advection and radiative cooling. The model output provides the heights of cloud base and inversion, the profiles of static energy and mixing ratio and also the vertical profiles of the turbulent fluxes.
The results of this steady-state model are in accordance with observations and other computations, and indicate, that the main processes are included into the model. The strong dependence of the results on some of the input parameters is shown by a sensitivity test.
