This paper is divided into two sections. First section tells us about the spin up time period. A sensitivity analysis has been done by taking 0hr, 24hr and 48 hr spin up time to know the accuracy of results which depend on spin up time. This spin up analysis has been done by taking different land surface parameterization schemes available in WRF model. The second part deals with the best suited scheme validation for precipitation for 3rd and 4th September 2012. The results shows that as the spinup time period increase the accuracy of results increased. Noah Land surface parameterization scheme is giving us best result both in terms of precipitation.
