Simulation of Pre-monsoon Cyclones of Two Contrasting Monsoon Years Using Mesoscale Model WRF (ARW) - Monitoring and Prediction of Tropical Cyclones in the Indian Ocean and Climate Change - page 327

Fig. 10: NEODAAS Dundee satellite images of Laila at 00 UTC of (a) 20 May
2010, (b) 21 May 2010, (c) 22 May 2010 and (d) 23 May 2010.
The predicted to accumulate rainfall during the past 24-hour period is
present with 27 and 9 km horizontal resolution of storm Laila in Figs 12(a) and
12(b). The model predicted rainfall is compared to the TRMM satellite rainfall.
The model captured the rainfall bands well along the coast. Overall model
over-estimate the accumulated rainfall compared to the TRMM rainfall. The
track positions of the simulated storm Laila with 27 and 9 km horizontal
resolution are shown in Figs 13(a) and 13(b). The model predicted track agrees
well with the IMD observational track.
The cyclonic storm Aila moved in a near-northerly direction throughout
its life period but the cyclone Laila moves towards the northeast direction
across the coast. In both the cases the KF cumulus convection and Lin et al.
micro physics gives good results. For the case of Aila YSU (Yonsei University)
PBL and for the case of Laila the MYJ (Mellor-Yamada-Janjic) eta PBL worked
well.
