Abstract
The gravity current is one of the components of sea-breeze circulation. The current structure and dynamics are changed during interaction of sea-breeze gravity current with synoptic wind. The numerical simulation of gravity current spreading towards the synoptic wind with shear is held using the non-hydrostatic two-dimensional model of compressible atmosphere. It is shown that the background wind shear significantly affect the gravity current structure, in particular determines its height and speed.
