Abstract

A new non-iterative approach has been developed to calculate surface fluxes. The range -5< (Formula pressented.) and (Formula pressented.) 30 is divided into eight regions, and in each of the regions, multiple linear regression is performed to obtain non-iterative solutions for surface fluxes. As compared to the other two most recent non-iterative schemes, we show that the suggested scheme has the smallest bias. The maximum relative errors of turbulent transfer coefficients for momentum C_M and sensible heat C_H, as compared to those obtained from the classic iterative method, are always smaller than 2 % from our new non-iterative scheme.
