Abstract
ONE OF THE PROBLEMS IN UNDERSTANDING THE DYNAMICS OF THE ATMOSPHERE AND ITS EFFECT ON THE ENVIRONMENT IS LACK OF RELIABLE RAINFALL DATA OR THEIR COMPLETE ABSENCE. RELIABLE RAINFALL DATA IS AN IMPORTANT PARAMETER IN MODELS USED FOR WEATHER PREDICTION, IS OF CONCERN TO ENVIRONMENTALISTS STUDYING THE EFFECT OF ACID RAIN, IS ESSENTIAL FOR WATER RESOURCES MANAGEMENT AND PLAYS A MAJOR ROLE IN MANY OTHER AREAS. A STOCHASTIC MODEL THAT CAPTURES THE ESSENCE OF RAINFALL PROCESSES IN TIME AND SPACE IS SUGGESTED. SUCH A MODEL IS PROPOSED TO BE USED TO INVESTIGATE THE APPLICABILITY AND USEFULNESS OF THE THRESHOLD METHOD, IN RAINFALL ESTIMATION. THE RAINFALL MODEL WILL SATISFY CERTAIN CONSISTENCY REQUIREMENTS. IT WILL CONSIST OF THREE PARTS; A STATIONARY CLOUD FIELD, A SPATIAL RANDOM RAIN FIELD, AND A MOVING WINDOW. ONCE THE MODEL IS VERIFIED, THE THRESHOLD METHOD WILL BE APPLIED TO THE DATA GENERATED BY IT.
