Problems solved by technology

Some of the methods mentioned above only consider the forecast error of the moving direction of the center of the tropical cyclone, and some consider the forecast error of the moving direction and moving speed of the center of the tropical cyclone at the same time, but none of them consider the range of the strong wind of the tropical cyclone when making maps to avoid typhoons Distribution

example

[0052] Example: At 12 o'clock (UT) on July 26, 2018, a certain ship was at 27.5°N, 155.0°E, sailing towards WSW, heading for a port in the Philippines, with a speed of 25 knots. At this time, Super Typhoon Jongdari No. 12 in 2018 is located at 23.5.°N, 140.1°E, and is moving towards NE with a speed of 22km / h. See Table 2 for Jongdari's center position, intensity, future direction, and speed every 6 hours (the data in Table 2 are obtained from weather reports).

[0053] Table 2 The position, strength, future direction and speed of Jongdari every 6 hours

[0054]

[0055] Correct the gale circle for the next 24 hours according to the position of the skylark every 6 hours, so that the ship will not fall into the gale circle in the next 24 hours to avoid the tropical cyclone. The drawing method is as follows Figure 8 shown. In the figure, H 1 , H 2 , H 3 , H 4 , H 5 Respectively represent the central position of Lark at 1200, 1800 hours on the 26th and 0000, 0600, 1200 ...

Abstract

The invention discloses a tropical cyclone prevention method. The method comprises the following steps of obtaining the longitude and latitude of a tropical cyclone center at t1, a future moving direction and moving speed, plotting a tropical cyclone center position H1 and a ship position A at t1 on a chart, drawing a line segment along the tropical cyclone moving direction by taking the H1 pointas a starting point, and drawing a first big wind circle by taking the tail end of the line segment as the center; taking H1 as an original point to draw tangent lines towards two sides of the strongwind circle to determine a dangerous area; making strong wind circles at t2, t3-Tn in sequence while drawing ship location points every other time T, and continuously adjusting the course to avoid acyclone. The large wind ring subjected to position prediction error correction serves as a dangerous area for ship avoidance, a certain distance is kept between the ship and the area, and the method for preventing the heat-zone cyclone has more reference basis and safety compared with a method for purely considering the position prediction error or the large wind ring.

Description

technical field [0001] The invention relates to an avoidance method, in particular to a tropical cyclone avoidance method. Background technique [0002] Tropical cyclone is the most powerful storm in the troposphere, and it is an important disastrous weather system that affects the navigation of ships at low and middle latitudes. When it comes, it brings strong winds, heavy rain, huge waves and storm surges, which pose a huge threat to sailing ships. Therefore, it is of great significance for ships to effectively avoid tropical cyclones and ensure navigation safety by understanding the distribution characteristics of strong winds in tropical cyclones and mastering their avoidance methods. There are many studies on tropical cyclones and strong winds. For example, Yang Yuhua et al. analyzed the distribution characteristics of strong winds caused by typhoons that landed in my country. Zeng Xinxin et al. analyzed the strong winds affected by typhoon "Kanu" in 0515 in Zhejiang fr...
