A Study of Near-Surface Winds in Marine Cyclones Using Multiple Satellite Sensors

Abstract Synoptic-scale surface wind fields are developed using data from two Special Sensor Microwave/Imager (SSM/1) passive radiometers and the European Remote Sensing Satellite-1 (ERS-1) scatterometer for the lifetime of two northern Pacific winter storms. The data are merged with surface wind output from a planetary boundary layer (PBL) model. The inputs to the PBL model are from the European Centre for Medium-Range Weather Forecasts (ECMWF) global analyses. A method for interpolating these analyses to the time of the satellite passage, while preserving fundamental storm characteristics, was developed. Composite wind fields are constructed each time one or more of the satellites views the storms. These composite wind fields are compared to the near-surface wind fields from ECMWF analyses within the storm domain and to buoy wind data on a point-by-point basis. Comparison with ECMWF analyses shows that the composite winds are slightly higher and contain more mesoscale variability. Comparison with buoy d...
