Being able to create accurate weather models for weather forecasting is essential for every aspect of the American economy, from aviation to shipping. To date, weather models have been primarily based on equations related to thermodynamics and fluid dynamics in the atmosphere. These models are tremendously computationally expensive and are typically run on large supercomputers.
