  In this paper, we incorporate seasonal variations of insolation into the
global climate model C-GOLDSTEIN. We use a new approach for modelling
insolation from the space perspective presented in the authors' earlier work
and build it into the existing climate model.
  Realistic monthly temperature distributions have been obtained after running
C-GOLDSTEIN with the new insolation component. Also, the average accuracy of
modelling the insolation within the model has been increased by 2%. In
addition, new types of experiments can now be performed with C-GOLDSTEIN, such
as the investigation of consequences of random variations of insolation on
temperature etc.
