Hello, Does anyone know of any successful uses of Neural Nets for predicting weather/climate, and if so, who developed the system and what type of net did they used ? I've heard Bernie Widrow at a meeting say that he had developed such an application, but I've not come across any publications of his describing it. Does anyone know if it is described in a paper ? Thanks, Eric Neumann eneumann@bbn.com

Here at NOAA in the Climate Research Division: Vernon Derr has implemented a simple backprop net to predict the El Nino current. He will be publishing in a few months and would be happy to answer any questions you might have (303-497-5975 or v.derr@omnet.nasa.gov) I also have a paper about forecasting 12 hour 500 mb height data: Richard S. Leblang "A Neural Network Forecast Demonstration" Central Region Technical Attachment 90-39, National Weather Service Forecast Office, Bismarck, North Dakota If you count forecasting solar flares (solar "weather"): I wrote a system for the Space Environment Lab here called TheoNet. It uses a simple 3-layer backprop net and past solar data to predict flares and their intensity. It was presented and published at NIPS '88: Richard Fozzard, "A Connectionist Expert System That Actually Works", with Gary Bradshaw and Lou Ceci, Advances in Neural Information Processing Systems, D.
