Abstract
We evaluated the 10-m wind speed, wind direction, and 2-m temperature of the Prydz Bay region (Ant-arctica) using five reanalysis products: the European Centre for Medium-Range Weather Forecasts Interim Reanalysis, Japanese 25-year Reanalysis, Japanese 55-year Reanalysis, Climate Forecast System Reanalysis, and Modern Era Retrospective-Analysis for Research and Application. The reanalysis products were com-pared with observations acquired by two manual weather stations and three automatic weather stations during 2007. Examination of the monthly mean and seasonal differences revealed that reanalysis wind speeds were lower than station observations at Mawson but higher at the other stations. Discrepancies in wind di-rection between the observations and the reanalysis datasets were small. The 2-m temperatures of the re-analysis datasets were lower than observed at the manual weather stations. There was no consistent charac-teristic in the differences between the 2-m temperatures from the reanalysis datasets and the data from the automatic weather stations. We also evaluated 6-hourly data at Mawson. It was found that the reanalysis datasets overestimated wind speed at low wind speeds (<5 m/s) and underestimated wind speed at high wind speeds (>15 m/s). In addition, the number of strong wind events observed at Mawson was significantly higher than indicated by the reanalysis datasets.关键词
