Embodiment Construction

[0027] In the following, only some exemplary embodiments are briefly described. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. Accordingly, the drawings and descriptions are to be regarded as illustrative in nature and not restrictive.

[0028] Before discussing the exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowcharts describe operations as sequential processing, many of the operations may be performed in parallel, concurrently, or simultaneously. In addition, the order of operations can be rearranged. The process may be terminated when its operations are complete, but may also have additional steps not included in the figure. The processing may correspond to a method, function, procedure, subroutine, subroutine, o...

Abstract

The invention relates to a method for establishing a weather forecasting model. The method includes the steps: step S1: acquiring historical weather forecast data of a geographical location, wherein the historical weather forecast data includes a plurality of features; step S2: acquiring weather record data of the geographical location, wherein the weather record data includes a weather indicator;step S3: using the weather record data to extract a feature or a feature group associated with the weather indicator from the plurality of features; step S4: taking the weather record data as a sample label to process the feature or the feature group in the historical weather forecast data, and establishing the weather forecasting model. The invention further relates to a weather forecasting method and device using the weather forecasting model.

Description

technical field [0001] The present application relates to the field of weather forecasting, in particular to a method for establishing a rain and snow phase prediction model and a method for predicting the rain and snow phase. Background technique [0002] In winter, as the temperature drops, the phase state of precipitation is difficult to characterize under different weather conditions in different regions. There may be multiple changes in the rain and snow state in a short period of time. Some current prediction methods mainly use a single parameter such as ground temperature to predict the phase state of rain and snow. It is said that there is a lot of instability, which also has a bad impact on the user experience. [0003] In some current applications, in order to allow users to have a more intuitive understanding of the precipitation phase in the current area, the rainfall will be processed in the results of the short-term forecast, and the user will be prompted whet...
