Embodiment Construction

[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0028] The invention discloses a method and system for predicting ozone concentration in different regions. In order to illustrate the technical solution more clearly, the prediction data of Beijing in 2013-2014 is taken as an example below for illustration. It should be emphasized that the method and system of the present invention are not limited to the prediction of ozone regions in Beijing, and are also applicable to the prediction of ozone regions in any other regions.

[0029] The six districts of the city (Dongcheng, Xicheng, Chaoyang, Haidian, Fengtai, Shijingshan); the northwest (Changping, Yanqing); the northeast (Huairou, Miyun, Pinggu, Shunyi); the southeast (Tongzhou) issued by the Beijing Environmental Protec...

Abstract

The invention relates to a prediction method for ozone concentration. The method comprises: historical meteorological data of a to-be-predicted area are obtained; a plurality of meteorological factors are selected and are used as influence factors; and with a multi-parameter fitting way, a prediction equation of ozone concentration is established by using the multiple meteorological factors as factors, prediction values of the meteorological factors and/or practical measuring values are substituted into the prediction equation, and then the equation is solved to predict a O3-8h value on the day needing prediction. According to the invention, the method is simple and is easy to operation; and the method can be implemented at different area instead of being restricted to Beijing and can be widely applied to the whole country. In the established partition forecasting system, functions of weather map downloading and assistant analysis are provided. Meanwhile, on the basis of a numerical value prediction simulation result, the expert carries out determination and correction further to form integrated prediction, thereby providing decision-making information for the administrative department.

Description

technical field [0001] The invention relates to the field of weather forecasting, and more particularly relates to a method and system for zone-by-area forecasting of ozone concentration. Background technique [0002] O in the atmospheric environment of Beijing 3 Pollution issues have drawn widespread attention from the State Council, the Beijing Municipal Government, and the general public. In February 2012, the executive meeting of the State Council deliberated and passed the "Beijing 2012-2020 Air Pollution Control Measures", requiring that by 2020, the hours of ozone exceeding the standard in Beijing will be reduced by 30% compared with 2010, and the annual control will be around 200h ;O 3 Concentration level is an important indicator of atmospheric oxidation state, atmospheric O 3 The control has O 3 and PM 2.5 Improved dual ambient effects. Theoretically control NO x and VOCs, etc. emissions can be greatly reduced O 3 concentration, but actually O 3 There is n...
