【摘要】 围绕日常天气预报的需求和为区域数值天气预报模式定义天气背景场和初值场的需要 ,针对 92 1 0工程的MICAPS系统中T1 0 6谱模式的客观分析场和预报场的数据存储及显示中的截断误差问题 ,提出了改进的方案 ,并定量分析比较了T1 0 6、欧洲中心ECMWF、华盛顿KWBC和日本JAPAN数值模式对天气环流形势的“快照”效果和统计误差更多还原

【Abstract】 For the need of daily weather prediction and an urgent call for the definition of ambient field as the initial input of regional forecasting model,the problem of truncation error in T106 dataset stored and displayed in MICAPS is discussed and indeed has been solved.The image snapshot effects of the spectra model T106 of China were also quantitatively analyzed,the ECMWF model,the JAPAN model and the KWBC Model,as well as their levels of statistic errors.更多还原
