Prediction of inversion strengths and heights from A 1-D nocturnal boundary layer model

Abstract

A 1-D numerical model for the nocturnal boundary layer is developed which is capable of predicting inversion heights and strengths successfully. The model uses two distinct length scales for the dissipation of turbulent energy and for transfer of heat and momentum within the Planetary Boundary Layer (PBL). The wind and potential temperature profiles obtained from the present model are compared with observations and the agreement is found to be good, viz., the RMSE for inversion height is found to be 71 m and that for inversion strength is found to be 2.0 °C.
