Method and system for forecasting heavy air pollution weather

Abstract

An air heavy pollution weather forecast method comprises the steps of collecting and obtaining the historical meteorological data of a long time sequence of a to-be-forecasted area; selecting a plurality of meteorological parameters as influence factors; establishing an air heavy pollution forecast equation in a fitting manner and by taking the plurality of selected meteorological parameters as factors, substituting the forecast numerical values of the meteorological parameters of a weather research forecast mode into the forecast equation, and solving the equation to forecast the future heavy pollution weather. The present invention also relates to an air heavy pollution weather forecast system. According to the present invention, the weather typing and a meteorological element discrimination equation are combined for the first time to discriminate the future possible heavy pollution process, the number of the representative meteorological factors selected by the established discrimination equation is few, a heavy pollution case discrimination effect is good, and a simpler and practical operation interface is established; the air heavy pollution weather forecast method is the effective supplement of a heavy pollution statistics forecast technology and a numerical value forecast technology, is simple, is easy to realize, is less in cost investment, can provide technical support for the heavy pollution early warning.

Description

technical field [0001] The invention relates to the field of weather forecasting, and more particularly to a forecasting method and system for heavy air pollution weather. Background technique [0002] In recent years, with the development of my country's economy and the expansion of production capacity, large-scale smog and other heavily polluted weather have begun to appear in the north, which has seriously affected normal production and life and damaged the physical and mental health of the majority of people. To this end, some areas have begun to implement a red warning mechanism for heavily polluted weather. By issuing red warning information, there are expected suspensions of classes and work, as well as traffic restrictions, to control further emissions from pollution sources and prevent primary school students and young children from being exposed to heavily polluted outdoors. [0003] However, the current heavy pollution forecasting mechanism mainly relies on manual...

AI Technical Summary

Problems solved by technology

[0003] However, the current heavy pollution forecasting mechanism mainly relies on manual forecasting, and there are large errors. Once the red warning is activated, but the weather conditions do not actually deteriorate, it will bring great losses to the economy of our country and the lives of the people.

In addition, my country only began to officially monitor and release PM2.5 values ​​in 2013. Due to the lack of previous data, many existing prediction methods cannot be carried out due to lack of data.
