The Impacts of Satellite Remotely Sensed Winds and Total Precipitable Vapour in WRF Tropical Cyclone Track Forecasts

Figure 7

Improvement of track simulations of Katrina (2005) through assimilating SSM/I and QSCAT observations. Model simulated tracks for Hurricane Katrina commencing at 00 UTC on 25 August 2005. The black dashed line is the forecast control case. The solid black line is best track data; the green line represents the case of assimilating SSM/I and one QSCAT. Assimilation of one QSCAT surface wind vector field is shown in red, and the one assimilation of SSMI and two QSCAT observations are shown in brown.
