Preliminary Comparison and Analysis of Air Temperature and SST Based on Reanalysis and Observation Data over Jiangsu Sea Area
摘要
Abstract
The paper compared three reanalysis data by the air temperature and SST based on the observa-tion data over the Jiangsu sea area.The results showed that the air temperature and SST of reanalysis data were highly consistent with the observation data,moreover,the consistency of SST was better.Among the three reanalysis data,the reliability of ERA5 was better than that of JRA-55 and NCEP.The consis-tency between the reanalysis data and the observation data was highest in Waikejiao observation station which was the farther offshore observation station.During periods of typhoon influence,the reanalysis data were closer to the observation data at Lyusi and Waikejiao observation station.At the Lianyungang observation station closer to the shore,there was a greater difference between the reanalysis data and the observation data.During the period of air temperature drop caused by cold air,the difference between re-analysis data and observation data was smaller.While during the temperature recovery period,the reanaly-sis data was significantly higher than the observation data at Lyusi and Waikejiao observation station.Dur-ing the influence of cold air,the reduction of SST reflected by the reanalysis data was significantly lower than the observation data.The results provide baseline for the study on the applicability and reliability of reanalysis data in Jiangsu sea area.关键词
