Embodiment Construction

[0045] Below in conjunction with accompanying drawing and example, the present invention is described in further detail:

[0046] Comprise three main steps in the real-time process of the present invention:

[0047] Step 1: Analyze time-varying tropical cyclone meteorological data and establish a tropical cyclone model suitable for subsequent drawing and simulation:

[0048] The time-varying tropical cyclone meteorological data is based on the grid data. By extracting the grid data, a particle-based particle model can be established, so that a unified data model can be used in the drawing and simulation process. Through the process of analysis drawing (see step 3) and simulation (see step 2), the designed particle model includes the following properties:

[0049] 1. The most basic variable in the simulation and drawing process of particle position is used to calculate the smooth core center position of the particle and calculate the next position of the particle at the same t...

Abstract

The invention discloses a tropical cyclone dynamic simulation method based on time-varying weather data, and belongs to the computer graphics related technology. The method mainly comprises a tropical cyclone modeling method based on the weather data, a cloud drawing algorithm method of multiple forward scatterings, and a tropical cyclone simulation algorithm method of a fluid based on a position, and the specific steps are as follows: first analyzing the time-varying weather data of the tropical cyclone to extract velocity field data for the fluid simulation use, extracting cloud intensity related data, establishing a particle model of a cloud at the same time, modeling graphic metadata suitable for the computer graphics drawing; and then vividly displaying the graphic metadata; and finally realizing the simulation display of the tropical cyclone in the weather data by use of the fluid simulation algorithm based on the position according to the established graphic model.

Description

technical field [0001] The invention relates to a tropical cyclone dynamic simulation method based on time-varying meteorological data, which belongs to the field of computer graphics, especially cloud modeling. Background technique [0002] A tropical cyclone (Tropical Cyclone, referred to as TC) refers to a rapidly rotating storm weather system with a low pressure center and a spiral cloud body, accompanied by strong winds, lightning, rainstorms, etc., also known as typhoons, Hurricanes, tropical storms, cyclones, tropical depressions, etc. A mature tropical cyclone usually has a complete structure, mainly including eye, ground low pressure, warm core, dense cloud area in the center, eye wall, spiral rainband, and outward diffuse circulation. [0003] The simulation and simulation technology of tropical cyclone has always been the focus and difficulty of acting research in the fields of meteorology and ocean, and in the field of computer graphics and imaging, tropical cyc...
