A 2-D Non-local Closure Model for Atmospheric Boundary Layer Simulations

In this paper a new approach for PBL simulation, the non-local closure scheme based on the transient turbu-lence theory has been used. It was set up as an alternative to local closure schemes which physical concept is reasona-ble and distinct. A 2-D non-local closure model was developed in order to study the PBL structure and simulate some interesting atmospheric processes over non-uniform underlying surface, especially under the convective and unique weather conditions, such as sea-land circulation and the TIBL structure. The modelled results show good agreement with field measurement.
