Abstract

The invention discloses a temperature forecasting method and equipment. The method comprises the following steps of: acquiring a first forecast field sequence and an observation field sequence of each preset numerical mode in a mode set at different forecasting time periods; determining a second forecast field sequence based on the first forecast field sequence and the observation field sequence; determining a weight coefficient of each preset numerical mode according to the training forecast error of a training period sample of each preset numerical mode; and performing weighted integration on the second forecast field sequence according to each weight coefficient, and then outputting a final forecast field. Therefore, the accuracy of temperature forecast is improved.

Description

technical field

[0001] The present application relates to the technical field of weather forecasting, and more particularly, to a method and device for temperature forecasting. Background technique

[0002] Weather forecast is closely related to people's life and national economy, especially temperature is one of the important meteorological elements. Due to the influence of various geographical and environmental factors in some areas, the accuracy of temperature forecasting is not high. For example, Xinjiang is located in the northwest arid region, far from the ocean, with large diurnal variation of the sun's height, and complex terrain and underlying surface. The difference is large, and the temperature forecast (especially the maximum and minimum temperature forecast) is more difficult. At present, the accuracy rate of regional temperature forecast in Xinjiang is 70-80%, which cannot meet the needs of society.

[0003] Numerical weather forecasting refers to solving the...

Embodiment Construction

[0053] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0054]As mentioned in the background art, in the prior art, due to the uncertainty of the initial field of the model and the existence of systematic deviations, there is a certain difference between the prediction result and the actual situation.

[0055] An embodiment of the present invention proposes a method for temperature forecasting, obtaining a first forecast field sequence and an observation field sequence of each preset numerical model in...
