  1. Computers and Weather Michael Drews

  2. History of Data Collection • Barometer (1643) • Weather balloons (1896) • Weather buoys (1951) • Doppler Radar (1940s) • Satellites (1960 - TIROS1)

  3. History of Forecasting • First forecasting calculations were done by hand (1922) • Lewis Fry Richardson • ENIAC computer performs first forecast (1950) • US National Meteorological Center develops atmosphere model (1966) • Increased computing power increases accuracy • Nowcasting • Supercomputers

  4. Societal Problems • Society depends heavily on forecasts • Incorrect predictions • Sunday golfing • Severe weather forecasts not taken seriously • Hurricane Katrina • Society’s susceptibility to severe weather • Power outages, structural damage • Transportation issues

  5. Solutions? • LOTS of data -> Machine Learning • Powerful algorithms for pattern recognition • Distributed/Cloud computing
