Embodiment Construction

[0050] The present invention will be further illustrated below in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. After reading the present invention, those skilled in the art all fall into the appended claims of the present application to the amendments of various equivalent forms of the present invention limited range.

[0051] The present invention first establishes an automatic identification system for typhoons in the Northwest Pacific Ocean. The satellite data, environmental field, and sea temperature field data of the typhoon to be judged are input into the automatic identification system, and the system will calculate a series of physical characteristics of the typhoon, and then Based on these characteristics, "pre-screening + linear discriminant (or BP neural network)" automatic identifi...

Abstract

The invention discloses an automatic identifying system of northwest Pacific Ocean annular tropical cyclone. Firstly, an automatic identifying system specific to the northwest Pacific Ocean annular tropical cyclone is built up; typhoon satellite data, environment field, sea temperature field data to be judged are input to the automatic identifying system; the system can automatically identify a series of physical features of the typhoon on the basis of these feature parameters through pre-screening and linear judgment or BP neutral network, and warn the typhoon in accordance with the feature of the northwest Pacific Ocean annular tropical cyclone, thereby providing help for forecasting this kind of typhoon.

Description

technical field [0001] The invention belongs to the prediction and identification technology of the atmospheric system, in particular to an automatic identification and alarm system for annular typhoons in the Northwest Pacific Ocean. Background technique [0002] Annular typhoons have the characteristics of high intensity, long duration, and difficulty in forecasting. The Northwest Pacific ring-shaped typhoon is concentrated in the generation area and has a high probability of landing, which continues to pose a greater threat to East Asia, but it has not yet received sufficient attention. The current prediction of typhoons is based on the micro and environmental conditions of the eastern Pacific and Atlantic ring hurricanes, and establishes screening and identification, so as to establish an objective identification algorithm for Pacific and Atlantic ring hurricanes. In terms of automatic identification, early warning and forecasting, it is still impossible to achieve timel...
