An Atmospheric Simulation System for AviationRequirements over Northern Latitudes

摘要

Most aviation accidents and disasters can be linked in one way or another to weather conditions – fog and precipitation, icing, high winds, and turbulence. Complex terrain features contribute to the formation of these inclement weather scenarios. The current operational numerical weather prediction (NWP) models lack the ability to resolve and effectively represent the complex terrain features especially that of the data-sparse Northern latitudes. The Operational Multiscale Environment model with Grid Adaptivity (OMEGA) presents a new paradigm in NWP, well-suited for application to meteorological modeling over such environments. In this paper the details of OMEGA and its applicability to aviation forecasting over Northern latitudes are presented.
