Laval95 Laval, K., 1995: Sensitivity of the monsoon to land-surface processes in the LMD GCM. Abstracts of the First International AMIP Scientific Conference, Monterey, California, 68.

Numerical experiments with the LMD GCM have been carried out with two different Lhomond parameterizations of land-surface processes. The first one is the usual "bucket model" with a simple reservoir of soil moisture and no vegetation. The second one is a scheme describing the different types of vegetation, called SECHIBA.

We describe the simulation of monsoon in both integrations, over the period 1979-88. We analyse the differences obtained in the hydrological cycle over the monsoon region. In order to try to understand the role of land-surface processes in the monsoon evolution, additional integrations for the wet and dry years have been performed.
