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

Decrease of cost functions (normalized by the initial cost function values ), (a) for Ketsana 2003 and (b) for Katrina 2005. Comparisons among Q, SQ, and S2Q within each TC case are not preferred because the cost functions are of different structure and of very different initial values. For Ketsana, the decrease of cost function is more efficient than that for Katrina, for all three cases of assimilating remotely sensed information.
