Wind deflection tower falling early warning method and system based on WRF mode

The invention provides a wind deflection tower falling early warning method and system based on a WRF mode, and the method comprises the steps: selecting an early warning region, carrying out the WRF mode simulation in combination with the tower falling data of the early warning region for many years, and determining an optimal parameterization scheme suitable for the early warning region; extracting wind deflection tower falling key factors, calculating the weight of each key factor by using tower falling example data simulated in a WRF mode, and constructing a wind deflection tower falling early warning index range; and based on the obtained optimal parameterization scheme, carrying out wind deflection tower collapse key factor forecasting and early warning index forecasting by adopting a wind deflection tower collapse early warning index range. The parameterization scheme used in WRF forecasting is suitable for a simulated area, the forecasting effect is better, forecasting and early warning of the windage
