Storm Forecast Simulator

The Storm Forecast Simulator is not just a tool; it's a comprehensive training system designed for both budding and seasoned storm chasers and forecasters. This simulator runs on Windows, offering a unique blend of education and simulation for severe weather forecasting. With an impressive archive that spans from 1979 to 2009, users have access to over 18,700 graphic products across 232 significant chase days, making it a treasure trove of meteorological history. This simulator challenges users to issue accurate forecasts and severe weather watches, testing their skills against 50 simulated chasers who react based on the issued outlooks. It's a test of both knowledge and strategy, where issuing a tornado watch on a clear day could lead to frustration among the virtual chaser community.
