AFGWC Air Stagnation Model,

Abstract

The Air Stagnation Model (ASM) developed at the Air Force Global Weather Central (AFGWC) is designed to provide air stagnation data to Air Force installations located overseas where mesoscale data are available. Parameters are derived from the AFGWC Boundary Layer Model (BLM) data and the AFGWC Meso-Scale Prediction Model data. Precipitation forecasts from the Macro-Scale Cloud Module (MSC) are also used. Since the BLM forecasts are only available through 24 hours, the 36-hour outlook uses data from the AFGWC Macro-Scale Baroclinic Prediction Model, the MSC and the 1000-mb Prognostic Model. The techniques used in the ASM are similar to those used by the National Weather Service (NWS). The air stagnation data include mixing depth, transport wind in the mixing layer, ventilation value in the mixing layer, meteorological stagnation index (MSI), times of maximum and minimum MSI and the maximum and minimum MSI.
