Abstract:
In January 2013, there were several severe fog haze events occurred in Beijing, with the mean visibility being less than 92 km and the PM25 concentration greater than 800 μg/m3 The causes and features are analyzed. The results indicate that the lasting fog haze weather was caused by the stable stratification, continuous southerly winds, and lower air temperature. According to the service experiences, the measures in forecasting and service are discussed in detail. In forecasting, meteorological agencies should take advantage of their technologies, such as numerical simulation and weather forecasting, to provide accurate fog haze forecasts and visualized products for the government, aiming at the regional distribution features of fog haze weather. In service, meteorological agencies should play their special role to provide tailored service according to the demands of the government, public, and end users timely. Some suggestions on fog haze service are given.
