Rainfall estimation using A-PHONN model

An adaptive multi-polynomial high order neural network (A-PHONN) model has been developed. The A-PHONN model for estimating heavy convective rainfall from satellite data has been tested as well. The A-PHONN model has 6% to 16% more accuracy than the PT-HONN (polynomial and trigonometric polynomial model) and PHONN (polynomial higher order neural network) models. Using the ANSER-plus expert system, the average rainfall estimate errors for the total precipitation event could be reduced to less than 20%.
