摘　　要：选择不同下垫面代表性厂址,利用观测数据,对CALMET嵌入核事故后果评价系统的有效性进行验证分析。结果表明:CALMET能够较为准确地模拟风向、风速和温度的日变化过程;滨海厂址主风向角偏差在一个风向角内,风速的平均绝对误差在2 m/s内,温度的平均绝对误差在2℃左右;内陆厂址,主风向角偏差在两个风向角内,风速的平均绝对误差小于2 m/s,温度的平均绝对误差在2℃内;CALMET模拟24 h的平均运行时间为15.84 s,可满足应急响应的需求。Selecting representative plant sites with different underlying surfaces,the effectiveness of CALMET embedded in the nuclear accident consequence assessment system was verified and analyzed using observation data.The results indicate that CALMET can accurately simulate the daily variation process of wind direction,wind speed,and temperature;The deviation of the main wind direction angle at the coastal factory site is within one wind direction angle,the average absolute error of wind speed is within 2 m/s,and the average absolute error of temperature is around 2 C;At the inland factory site,the deviation of the main wind direction angle is within two wind directions,the average absolute error of wind speed is less than 2 m/s,and the average absolute error of temperature is within 2℃;Meanwhile,the average running time of CALMET simulation for 24 hours is 15.84 seconds,which can meet the requirements of emergency response.
