A Note on the Numerical Modeling of the Flux of Heat from the Ground

Abstract

The heat stored in the ground and the transport of this heat to and from the atmosphere can be important considerations in numerical models of the atmosphere. This note considers the preformance of the conventional approach to the numerical modeling of ground flux using a number of levels in the ground. In particular, a simple efficient analogue is suggested which can be used to realistically derive the ground flux. Only the mathematical implications are considered; it is left up to the individual modeler to grapple with the problems of variable conductivity, homogeneity, etc.
