【摘要】 利用T213的各时次500hPa高空形势场和海平面气压场及其850hPa温度、相对湿度、水汽通量散度、uv风场预报对2003年4月中旬寒潮天气进行了检验。结果表明,该产品对环流形势预报和调整可信度高,并且对冷空气发生的起止时间、强度及其相应的强沙尘、降水时段和降水的落区都具有较强的预报能力。更多还原

【Abstract】 Based on the forecasted 500hPa situation,the sea-level barometric field,the temperatures,relative humidity,vapor flux divergence,uv wind field of 850hPa of T213 NWP Mode,the cold wave in the middle ten days of April,2003 was verified.The results showed that the model had high reliability for the situation forecast and adjust of circulation,and the capabilities to forecast the start-stop time and intensity of cold air affecting,the strong sand dust,the period of and area of precipitation,etc.更多还原
