Characteristics Of Haze Distribution And The Forecast Method Research In Inner Mongolia

By using conventional meteorological data, NCEP reanalysis data, MICAPS data and High altitude detection data, to analyze the time and space distribution characteristics of fog and haze weather in Inner Mongolia. Get the conclusion of the yearly, monthly, daily change of haze weather, and the analysis result indicates that the fog and haze days in space distribution is uneven. From 2000 to 2013,the distribution of haze, obvious regional characteristic, haze days highest region was located in wuhai area, Hohhot and southeast area of Tongliao city, the least region was located in Xilin Hot, and the haze day didn’t show up in Bayan Hot during these time. The haze day was mainly focused in November to March, and seldom show up in summer from May to July.From 1971 to 2008,the fog days were gradually reduced in the Inner Mongolia. The fog was mainly happened in January and July to September, and it mainly appeared in the from 2 a.m to 9 a.m, which shows that the happening of fog in our area is mainly due to radiation cooling.Summarizing the different types of circulation form and influence system of fog and haze, including High and low altitude weather form, surface pressure field, physical causes and so on. By analysing a typical case of fog and haze in Hohhot region in weather situation and physical quantity, summarizing the forecast conceptual model of fog and haze. Giving the meaningful forecast indexes which have guiding significance to forecast work of fog and haze. Analysing of the dangers of smog to human beings and put forward prevention measures from meteorological and environmental protection aspect.
