THE INFLUENCE OF CUT-OFF LOWS ON SULFATE BURDENS OVER THE NORTH ATLANTIC DURING APRIL, 1987 Carmen M. Benkovitz
INTRODUCTION Sulfate aerosol is of great interest because of its role a scattering solar radiation and modifying microphysical properties of clouds, with possible resultant influence on the earth's radiation balance and climate (Hansen et al., 2000; Haywood et al., 1999; Kiehl et al., 2000). Th...

| Summary: | INTRODUCTION Sulfate aerosol is of great interest because of its role a scattering solar radiation and modifying microphysical properties of clouds, with possible resultant influence on the earth's radiation balance and climate (Hansen et al., 2000; Haywood et al., 1999; Kiehl et al., 2000). This material derives mainly from anthropogenic emissions of sulfur dioxide (SO 2 ) followed by oxidation in the atmosphere to form sulfate aerosol, which in turn is removed mainly in precipitation. At any given time the distributions of SO 2 and sulfate are dependent on the synoptic-scale meteorological fields over the past several days. In view of the temporal variation in loadings that results from the variability in thecontrolling synoptic-scale meteorology, it is virtually mandatory for the purpose of performing short-term comparisons with observations to drive the models with observation-derived synoptic meteorological data.
