Abstract

The present invention provides an ensemble forecasting method and system for numerical forecasting of atmospheric haze, wherein the ensemble forecasting method includes: selecting an area where numerical forecasting of haze needs to be carried out, and dividing the area into grids of equal latitude and longitude; collecting multiple climate models From the initial field data and boundary condition data of each climate model, select the data of multiple different start times close to the current time; the data of different start time will be selected Perform interpolation according to the equal latitude and longitude grid to obtain grid data of uniform grid points; select the regional numerical prediction model and select different boundary layer parameterization schemes, input the grid data into the regional numerical prediction model respectively, and carry out the grid data Numerical integration calculations generate multiple sets of spatial distribution data of air pollutants at different times in the future. The method and system can scientifically guide power grid enterprises to optimize power generation scheduling, thereby reducing smog concentration.

Description

technical field [0001] The invention relates to the technical field of atmospheric environment and power grid dispatching, in particular to an ensemble forecasting method and system for numerical forecasting of atmospheric haze. Background technique [0002] With the continuous development and strengthening of my country's industrial volume, the sources of industrial emissions continue to increase, resulting in the frequent occurrence of atmospheric smog, which has a serious impact on the health of residents. [0003] When thermal power plants generate electricity, a large amount of smoke is produced, which is one of the reasons for the formation of atmospheric smog. When the atmospheric smog is serious, the use of thermal power plants to generate electricity will increase the concentration of smog. [0004] If the power grid enterprises can carry out reasonable power generation scheduling, increase the grid connection of clean energy, and appropriately reduce the use of th...
