A comparative study of spring reanalysis data of the Indian Ocean and the South China Sea
This paper adopts the independently developed EARR regional climate analysis model,selecting several elements in April 2015 that characterize the spring Indian Ocean and South China Sea regions:2m temperature,2m relative humidity,and 10m wind(including zonal and meridional wind)for data assimilation processing,and then comparing the reanalysis data obtained with the NCEP reanalysis data developed by the National Environmental Prediction Center(NCEP),the ERA-Interim reanalysis data developed by the European Centre for Medium-Range Weather Forecasts(ECMWF),the 55-year reanalysis data developed by the Japan Meteorological Agency(JMA)known as JRA-55,and the multi-meteorological precipitation data from the TRMM meteorological satellite sensors.The study focuses on the accuracy of climate prediction and the accuracy of forecasts of the EARR regional reanalysis data under the influence of topography,monsoon,and other factors in the two regions,as well as the advantages and disadvantages of the EARR regional analysis model in forecasting and climate analysis compared to other models.
