Abstract

The imapcts of microphyscial processes on the evolution of hurricane Erin 2001 MM5 version 3.5, were investigated. The effect of microphysical processes on horizontal and vertical distributions of hydrometeors was also discussed. Simulations with varying boundary layer schemes show larger variations in the lower and upper limit of pressure, pointing towards importance of surface exchange processes for the determination of the strength. Simulations with the new iterative condensation scheme, give higher central pressrue P min of 8 mbar and lower maximum tangantial velocity U max of 5 ms -1, pointing towards the criticality of condensation for the determination of hurricane strength.
