12 August 2010Impact of satellite surface wind observations on ocean surface wind
analyses and numerical weather prediction
Since the 1970s, an extensive series of data impact studies has been performed to evaluate and enhance the impact of
satellite surface wind data on ocean surface wind analyses and fluxes, atmospheric and oceanic modeling, and weather
prediction. These studies led to the first beneficial impacts of scatterometer winds on numerical weather prediction
(NWP), the development of the methodology to assimilate surface wind speeds derived from passive microwave
radiometry, and the operational use of satellite surface winds by marine forecasters and NWP models. In recent years,
the impact of these data on NWP has decreased as more competing data have become available; however, the results of
our recent experiments still show a very significant impact of satellite surface winds on ocean surface wind analyses and
on the prediction of selected storms over the oceans.
