On the Drag and Heat Transfer Coefficients over the Tibetan Plateau

Inspection of the land-air interaction over the Tibetan plateau helps better understanding weather and climate in China. We theoretically analyzes the solutions of momentum and heat transfer coefficient equations, and accordingly highlights the dependence of the momentum and heat transfer coefficients on (1) atmospheric stability parameter, Richardson number, (2) ratio of measurement height to surface aerodynamic roughness length, and (3) the ratio of surface aerodynamic roughness length to surface heat roughness length. The relationship between momentum and heat transfer coefficients and the influence of wind speed on momentum and heat transfer coefficients are clarified. The theoretical results are validated by using the data collected over the Tibetan plateau.
