Method and device for correcting station wind speed forecast result

Abstract

The invention provides a method and a device for correcting a station wind speed forecast result. The method comprises the following steps: acquiring meteorological data and landform data of a target forecast region in a current time period; inputting the meteorological data and the landform data into a meteorological feature extraction model to obtain meteorological features; obtaining historical wind speed forecasting results and future wind speed forecasting results of the target forecasting area by a preset number of wind speed forecasting models; for each wind speed prediction model, obtaining a model prediction error of the wind speed prediction model based on a historical wind speed prediction result and a wind speed measured value of the wind speed prediction model in the target prediction region; inputting the meteorological characteristics and each model prediction error into a wind speed correction model to obtain a prediction weight of each wind speed prediction model; and calculating a product of a future wind speed forecast result of each wind speed forecast model and the forecast weight, and obtaining a station wind speed forecast correction result of the target forecast area based on each product. The method can increase the accuracy of wind speed value forecasting.

Description

technical field [0001] The invention relates to the technical field of meteorological forecasting, in particular to a method and device for correcting wind speed forecasting results of a station. Background technique [0002] Wind speed forecasting is an important branch of meteorological forecasting, which has a very important impact on people's daily life, industrial and agricultural production, and environmental analysis. In order to accurately observe the wind speed, people have built multiple meteorological observation stations at different locations on the earth's surface to measure the wind speed in real time, and forecast the future wind speed according to the wind speed observation results of the meteorological observation stations. However, due to the many meteorological factors involved in the natural wind speed, the correlation between the factors is very complicated, and the accurate modeling and prediction of wind speed is more complex. As a result, the wind sp...
