Automatic identifying system of northwest Pacific Ocean annular tropical cyclone

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...

The Northwest Pacific ring-shaped typhoon is concentrated in the generation area and has a high probability of landing, which continues to pose a great 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 timely quick response
