[AAS05-P03] Numerical Study on the Diurnal Cycle of Precipitation Observed near the West Coast of Sumatra Island
Keywords:Diurnal Cycle of Precipitation, Simulation, Pre-YMC Observation Campaign
At first, we perfomed a one week simulation initialized at 00 UTC on November 28, 2015 with a cumulus parameterization. In this simulation, the movements of the precipitation systems were reproduced every day at least marginally. Comparisons of the SCALE-RM simulation with the Pre-YMC radiosonde data confirms that the zonal wind and the specific humidity were quite similar. Then, another simulation was performed by setting the initial time at 00 UTC on November 23, 2015. This calculation was performed without any cumulus parameterization. Precipitation was reproduced everyday over land but its migration toward offshore did not happen except for one day. We are planning to examine the reason for this difference possibly due to with or without the cumulus parameterization.
