An impact of ARMEX data on limited area model analysis and forecast system of India Meteorological Department - A preliminary study
Keywords:ARMEX, Data, Impact, Analysis, forecast system
During the Arabian Sea Monsoon Experiment (ARMEX) period India Meteorological Department (IMD) forecast products along with other products are utilised for day-to-day monitoring and providing the guidance to the field scientists engaged in the collection of meteorological and oceanographic data. In the present study, the operational analysis and forecast products of limited area forecast system for some of the major synoptic systems that occurred during the ARMEX period was investigated. Further, using the additional data available from ARMEX Phase-II namely SYNOP, upper air and also satellite data, the impact of these data in the IMD's operational limited area forecast system during the onset phase of monsoon 2003 has been investigated. Verification of analysis and forecast fields with this additional data has shown substantial improvement in the analysis and model predicted rainfall.
