摘　　要：应用2003年和2004年6月～8月天气形势资料和同期环境空气自动监测数据进行统计分析，建立夏季天气模式预报方法，同时应用2005年资料进行验证，预报效果较好，环境空气中首要污染物——可吸入颗粒物（PM10）的级别预报准确率、趋势预报准确率和总站发布预报范围准确率分别达到60％、80％和90％，该预报方法可作为业务预报使用。We analyzed the meteorological observed data and environmental air automatic monitoring data during June, July and August in 2003 and 2004. Through counting the data,we set up summer weather model forecasting method. We applied the data of 2005 to test this method. The forecasting results were good. The forecasting accuracies of grade, tendency and scale of the main contaminants--inhaled particle in the ambient air reached 60%, 80% and 90%, respectively. The forecasting method can be used in daily operation.
