Regional Trans-boundary Smoke and Haze in South-East Asia


Roland R. Draxler and Bruce B. Hicks


WMO Workshop 2 - 5 June, 1998


Abstract -  The National Oceanic and Atmospheric Administration's (NOAA) Air Resources Laboratory (ARL), which provides the research support for the development of operational pollutant transport and dispersion models for Washington's Regional Specialized Meteorological Center (RSMC), was requested by the U.S. State Department and Army Health Service to provide some forecast guidance regarding the transport and dispersal of smoke from the South-East Asian fires.  The identical model that is used for the Washington RSMC's radiological predictions was configured for smoke forecasts by assuming continuous point source particulate emissions from each of the major burn areas, different particle sizes, and multiple emission points.  The dispersion model was run twice a day on ARL's workstation using the Aviation Model (AVN) global forecast fields produced by NOAA's National Centers for Environmental Prediction (NCEP).  The dispersion model results were posted on ARL's web site.  This system is also employed for the smoke from the recent fires in Mexico and Central America.
