Abstract: A shallow-water model is developed to examine the dynamics of mountain-barrier jets over a mesoscale sloping valley between two mountain ridges. In this model, the cold air trapped in the valley is represented by a ...

Abstract: Numerical models of the atmosphere and aerosols are used to investigate mobilization and transport of Saharan dust over West Africa and the tropical Atlantic Ocean for 23?28 August 1974. We have found that mobilization ...

Abstract: Fu?Liou?s delta-four-stream (with a two-stream option) radiative transfer model has been implemented in the U.S. Navy?s Coupled Ocean?Atmosphere Mesoscale Prediction System (COAMPS)1 to calculate solar and thermal infrared ...

Abstract: The Lut Desert of Iran is an elongated valley oriented north-northwest to south-southeast. The valley descends southward to the Jaz Murian dry lake through a pass. The Navy?s Coupled Ocean?Atmosphere Mesoscale Prediction ...

Abstract: In support of the Department of Defense's Gulf War Illness study, the Naval Research Laboratory (NRL) has performed global and mesoscale meteorological reanalyses to provide a quantitative atmospheric characterization of ...

Abstract: Dust storms are a significant weather phenomenon in the Iraq region in winter and spring. Real-time dust forecasting using the U.S. Navy?s Coupled Ocean?Atmospheric Mesoscale Prediction System (COAMPS) with an in-line dust ...

Abstract: Aerosol optical depth measurements over Bahrain acquired through the ground-based Aerosol Robotic Network (AERONET) are analyzed. Optical depths obtained from ground-based sun/sky radiometers showed a pronounced temporal ...

Abstract: The U.S. Weather Research Program convenes expert working groups on a one-time basis to identify critical research needs in various problem areas. The most recent expert working group was charged to ?identify and delineate ...
