Recent collaborative efforts between NOAA's Hurricane Research Division (HRD) and the Cooperative Institute for Meteorological Satellite Studies (UW-CIMSS) have resulted in the development of several new satellite-derived products designed for tropical cyclone applications. These products utilize geostationary satellite winds produced at UW-CIMSS which are made available in real-time.
Low-level cloud-drift winds produced from the high-resolution visible channel on GOES -8/10 and GMS-5 are generated and adjusted to the surface using a combination of HRD's planetary boundary layer model and empirical optimizations derived from comparisons with in situ data in tropical cyclone environments. This allows for the analysis of both low-level and surface wind fields near and peripheral to the circulation center. Shortwave IR cloud-drift winds are currently being developed to compliment the visible winds for nighttime coverage.
Color enhanced 850 hPa relative vorticity products are now being produced in real-time by UW-CIMSS and are available for multiple ocean basins. This product is created from local, high-resolution 3-dimensional objective analyses that are strongly influenced by the assimilation of low-level cloud-drift satellite wind data. To promote its use as a diagnostic tool, the vorticity product is being made available as an animated 5-day java loop. This product has shown potential for use in tropical wave tracking as well as for examining interactions between environment features such as tropical cyclones, tropical waves and mid-latitude fronts.
