The radar altimeter aboard the U.S. Navy Geosat satellite was used to observe and track a cyclone pair which occurred during May 1986 in the equatorial Pacific. The data were binned into boxes 2¿ in latitude by 8¿ in longitude with a temporal resolution of 3 days. This smoothing in space and time lead to wind speed estimates substantially less than the instantaneous wind speeds. Nevertheless, the storm track derived from Geosat data was essentially the same as that obtained using imagery from a weather satellite, independent NOAA estimates of the storm tracks, and weather analyses by the Australian Royal Meteorological Service. This study demonstrates that Geosat wind speed data can be effectively used to investigate mesoscale storm features.
