Fine Scale Modeling and Forecasts of Upper Atmospheric Turbulence for Operational Use

ABSTRACT: The objective of this STTR Phase II project is to continue the development of a fine scale forecast model capability that will provide a technologically superior, high resolution atmospheric decision tool to accurately predict areas of clear air turbulence in the upper troposphere and lower stratosphere (UTLS). Accurate real time knowledge of the dynamics in the UTLS is critical to support operations in high impact turbulence environments. In Phase I, the feasibility of novel physics based modeling and multi-nesting techniques was demonstrated. Phase II will pursue advanced development of fast and scalable numerical algorithms and solvers using high resolution nested simulations. We will also investigate optimal operational configurations for an integrated hardware-software platform which uses state-of-the-art multi-core technologies for single analytic workloads to accelerate run-time performance for real time operational forecasting. BENEFIT: The Unmanned Aerial Vehicles (Global Hawk, Predator), U2, reconnaissance, and communication systems will benefit from this STTR project. Additional applications include forecasts in complex terrain or urban areas for problems related to aviation and Homeland Security.
