Abstract

Mesoscale models need high-resolution data on atmospheric parameters. QuikSCAT provides the horizontal components of winds over the global ocean with a very high horizontal resolution.  In this paper, QuikSCAT derived wind fields have been used to improve the initial state of mesoscale circulation in a non-hydrostatic mesoscale model. The comparison of initial state using global data with and without QuikSCAT data has clearly identified the benefits of addition of important mesoscale circulation features. Considering the wind circulation forecast, the control run that used the initial state without QuikSCAT data predict very weak low pressure area. In contrast, the experimental run with QuikSCAT data could forecast it up to 48 hours in a way that agreed well with the observed circulation.
