Technical Field

The invention relates to the field of airline weather, in particular to a method for forecasting airline weather.

Background

With the development of society, the navigation industry is continuously improved, and in order to improve the navigation safety, people usually make a course weather forecast, which means that navigation personnel can make a short-term weather forecast on a course by themselves by using the forecast result of a weather department;

the existing air route weather forecasting method has certain disadvantages in use, all weather forecasting information is generally obtained by the existing air route weather forecasting method at one time, an air route is designated according to all weather forecasts, received weather forecasting data are too large in use, the weather change speed on the sea surface is high, multiple groups of computing equipment are needed for processing, the cost is high, the existing air route is set according to all weather forecasting information, large-area air route changing is needed when weather fluctuation occurs, the existing air route is troublesome, and the use requirements of people are not met.

Preferably, in the step (2), the weather forecast information is selected from the group consisting of a ground analysis chart, a ground forecast chart, a wave analysis chart, a wave forecast chart, a tropical cyclone alarm chart, a current chart, an ice chart, a weather analysis chart, a weather cloud chart and a weather forecast chart.

Preferably, in the step (3), the weather drawing based on time refers to a severe weather time period marked at all places on the main navigation route, and the severe weather includes strong wind weather, heavy rain weather and heavy wave weather, and then the time period is marked on the map.

Preferably, in the step (4), the drawing coincident point refers to a coincident point between a time period corresponding to the ship navigation point on the map and a time period in severe weather at the position.

Preferably, in the step (5), the drawing coincident point information refers to a specific position and a specific time period, the receiving of the nearby weather forecast information refers to obtaining the weather forecast information nearby the position in the time period, and the nearby weather forecast information refers to the weather forecast information within 6-20 kilometers of the drawing coincident point position in the time period.

Preferably, in the step (6), when the partial course of the ship is changed according to the weather forecast information, a new sailing route without severe weather is selected according to the acquired weather forecast information and the sailing speed of the ship, and the step (1) is performed after the acquired new main sailing route replaces the main sailing route.
