| 摘 要： | 初步发展了一个空气污染准业务数值模式，该模式将修改过的二维Mass风场模式预报的风场据实测风廓线推广到三维，用有限元法求解欧位平流扩散方程，在此基础上，预报上海地区SO2指数和浓度分布。通过半年的试验，其结果与实测值基本一致，初步可用于业务预报使用。通过模拟表明，上海市的浓度高值区一般位于市区和郊区宝山，一天中早晨的浓度最大，傍晚次之，中午最小。

| Abstract: | A practical air pollution model is developed in this paper.This model includes modified two dimension Mass model whose forcasted wind field can be adjusted to the three dimensional wind field with the observed mean wind profile,and the three demensional Eulerian advection diffusion equation is solved by finite element method for atmospheric pollution. Based on these,forecast is made for the distribution of SO 2 concentration in Shanghai.Through half year experiments,the forecasted results show resemblance to the measured.So it can be used to practical forecast.Simulations show that the SO 2 high value area in Shanghai locates in Baoshan and urban area.In a day,SO 2 concentration is the highest in the morning,higher in the evening,the lowest at noon. |
