	<abstract content_type="html">Tropical cyclones are one of the most intense weather hazards over east coast
of India and create a lot of devastation through gale winds and torrential
floods while they cross the coast. So an attempt is made in this study to
simulate track and intensity of tropical cyclone &quot;Fanoos&quot;, which is formed
over the Bay of Bengal during 5â€“10 December 2005 by using mesoscale model
MM5. The simulated results are compared with the observed results of India
Meteorological Department (IMD); results show that the cumulus
parameterization scheme, Kain-Fritsch (KF) is more accurately simulated both
in track and intensity than the other Betts-Miller (BM) and Grell Schemes.
The reason for better performance of KF-1 scheme may be due to inclusion of
updrafts and downdrafts. The model could predict the minimum Central Sea
Level Pressure (CSLP) as 983 hPa as compared to the IMD reports of 984 hPa
and the wind speed is simulated at maximum 63 m/s compared to the IMD
estimates of 65 m/s. Secondly &quot;Fanoos&quot; development from the lagrangian
stand point in terms of vertical distribution of Potential Vorticity (PV) is
also carried out around cyclone centre.</abstract>
