Abstract A method for routinely verifying numerical weather prediction surface marine winds with satellite scatterometer is introduced. The from the Australian Bureau of Meteorology’s operational global and regional systems are evaluated. model layer described. Marine limited-area models compared observations, both in situ (anemometer) remote (scatterometer). 2-yr verification shows that wind speeds typically underestimated by approximately 5%, a greater bias meridional direction than zonal direction. also underestimates around 5%–10%. case study significant storm where larger errors occur, they due to an underestimation intensity, rather biases boundary parameterizations.
