Abstract

The invention discloses a typhoon center positioning method and device, and a typhoon path generation method. The typhoon center positioning method comprises the steps of firstly, acquiring bottom-layer wind field data, height field data and sea level air pressure data; then, identifying a low-voltage center of a monitoring area; judging whether an overlapping area exists between the low-pressurecenter and a vortex center of a bottom-layer wind field or not, whether a peripheral maximum wind speed value is greater than or equal to a preset threshold value or not and whether a central air pressure value is less than a preset air pressure value or not; and if so, taking as a candidate point of the typhoon center, judging whether a maximum value center and a minimum value center of an air pressure gradient in a horizontal direction and a vertical direction exist around the candidate point of the typhoon center at the same time, if so, conforming to typhoon characteristics, and taking thecandidate point of the typhoon as the typhoon center point. By implementing the embodiment of the invention, the typhoon center can be positioned before the formed typhoon is observed through a real-time cloud picture, then the real-time typhoon path is detected, and a problem of hysteresis of an existing typhoon center positioning technology is solved.

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 ...
