Problems solved by technology

[0002] At present, most domestic meteorological bureaus use numerical forecasting methods for typhoon prediction methods, but the prediction methods and models for these typhoon paths have certain limitations. For example, the prediction time is long and the algorithm complexity is too high. Large-scale computers are used for calculations, and the parameters required by the model are too complex, requiring a large amount of data to calculate and obtain the final result

Embodiment Construction

[0026] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] like figure 1 As shown, in the actual application process of a typhoon path prediction method designed in the present invention, based on historical typhoon data, the movement path of the initially expected typhoon is predicted, and the predicted movement path of the initially expected typhoon is obtained, which specifically includes the following steps:

[0028] Step 001. Use the function file() to read through the relevant meteorological website to obtain the parameter information of each preset parameter type corresponding to the initially expected typhoon to form the data set data_typhoon, and use the htmlspecialchars() function to convert the data_typhoon data set into Character type, and then use regular expressions to match the specific initial expected typhoon parameter information from the above data set,...

Abstract

The invention relates to a typhoon track forecast method. Similarity forecast is carried out on a typhoon moving track through using a technique based on example reasoning and combining an objective forecast method. Firstly, the time demanded by the traditional numerical forecast is greatly reduced in the forecast; with respect to that the traditional forecast method needs auxiliary operation of a large computer, on one hand, the forecast method designed by the invention is low in operation complexity, only a small server with relatively high configuration is needed; on the other hand, the parameters needed by the forecast method designed by the invention are relatively few, a great deal of parameter input is unnecessary; and the working efficiency of typhoon track forecast is greatly improved.

Description

technical field [0001] The invention relates to a typhoon track prediction method, which belongs to the technical field of typhoon prediction. Background technique [0002] At present, most domestic meteorological bureaus use numerical forecasting methods for typhoon prediction methods, but the prediction methods and models for these typhoon paths have certain limitations. For example, the prediction time is long and the algorithm complexity is too high. Large-scale computers are used to perform calculations, and the parameters required by the model are too complex, requiring a large amount of data to calculate and obtain the final result. Contents of the invention [0003] In view of the above-mentioned technical problems, the technical problem to be solved by the present invention is to provide a typhoon path prediction method, which adopts the technology based on example reasoning and combines the objective forecast method to predict the similarity of the typhoon moveme...
