Abstract: Monthly mean global forecasts for January 1975 have been computed with the GISS model from four slightly different sets of initial conditions?a ?control? state and three random perturbations thereof?to simulate the effects ...

Abstract: Results f rum a series of numerical simulations are presented to show the effects of changes in albedo on rainfall in six areas, two each in Africa, Asia and North America. Each pair consists of a semi?arid area lying at ...
