The invention discloses a typhoon center positioning method, device and typhoon path generation method. The typhoon center positioning method first obtains bottom wind field data, height field data and sea level air pressure data, and then identifies the low pressure center in the monitoring area, and then Then determine whether there is an overlapping area between the low pressure center and the vortex center of the bottom wind field, whether the peripheral maximum wind speed value is greater than or equal to the preset wind speed threshold and whether the central air pressure value is less than the preset air pressure value, and if so, it is used as a candidate point for the typhoon center, Judging whether there is a maximum center and a minimum center of the pressure gradient in the horizontal and vertical directions around the candidate point of the typhoon center, if there is, it conforms to the characteristics of the typhoon, and the candidate point of the typhoon is taken as the center point of the typhoon. By implementing the embodiments of the present invention, the center of the typhoon can be located before the typhoon is observed through the live cloud image, and then the real-time path of the typhoon can be detected, so as to solve the problem of lag in existing typhoon center positioning technology.
Description
technical field [0001] The invention relates to the technical field of typhoon monitoring, in particular to a typhoon center positioning method and a typhoon path generation method. Background technique [0002] At present, the typhoon center positioning forecast is based on numerical product forecasting. The existing typhoon forecasting methods are generally as follows: After the forecaster observes the formed typhoon through the live cloud image, the typhoon center is located by manual marking. At this time, the typhoon The central positioning point is the first point. At the next moment, the low-level numerical forecast products (pressure field and height field) are used to radiate outwards with a certain radius around this point, and then use the rolling iteration method to search for places other than the first point in a certain direction. The lowest value is used as the center of the typhoon at that moment, and finally achieves the purpose of using numerical forecast ...
