Data from three polar-orbiting satellite sensors were used to make a movie showing the evolution of near-surface winds of two northern Pacific winter storms. These data include wind vectors from the ERS-1 scatterometer and wind speeds from two DMSP SSM/I passive radiometers. There were 61 observations of the two storms over nine days. Wind fields were composited each time one or more of the satellites viewed the storms. Output from the University of Washington planetary boundary-layer model was used to augment the satellite data in the gaps between the swaths and in areas of missing SSM/I winds where contamination due to atmospheric liquid water obscured the surface. The boundary-layer model parameterizes the small-scale turbulence with diffusion coefficients and the large-scale eddies as a modification of the mean flow. Pressure and temperature analyses from ECMWF were used as input to the model. A scheme was developed to interpolate the analyses to the time of the satellite passage, preserving fundamental storm characteristics in the fields. This same method was used to interpolate the composite wind fields to five-minute time steps for the movie. The figure shows five stills of the first storm. The left column shows the wind speed and pressure fields. The right column shows the wind vector fields over the wind speeds. The scale is in m/s. The isobars are every 4 mb with the 1000 mb and 1004 mb isobars in bold.
