We study the accuracy of the finite differences discretization scheme for a 2-D simplified model of global tracer transport, in the case that the diffusion coefficients relating flux to the gradient of the mixing ratio have di...

The climate response of the Northern Hemisphere to the anthropogenic greenhouse gas forcing is studied with a zonally-averaged climate model. First, a simple method is proposed to improve the radiative forcing in climate models with a low vertical res...
