Deep Learning of Severe Weather Forecast Data
Abstract:
Attendees will learn how deep learning models identify severe weather hazards, how deep learning severe weather diagnosis compares with other machine learning methods, and what weather features deep learning considers most important for determining whether a storm will produce severe weather or not. Severe weather hazards, such as tornadoes, hail, high winds, and flash floods, cause billions of dollars in property damage and injure or kill hundreds of people in the U.S. each year. Improved forecasts of the potential for severe weather enables decision makers to take actions to save lives and property. Machine learning and deep learning models extract spatial information from observations and numerical weather prediction model output to predict the probability of severe weather based on whether or not some form of severe weather was reported by the public. Convolutional neural networks and generative adversarial networks are compared against principal component analysis encodings to determine how much skill deep learning adds over traditional methods. The deep learning models are interrogated to identify important variables and spatial features for severe weather prediction.
