Research on Visualization of the Wind Field Streamline Based on GRIB Data

Abstract:

GRIB code has good features: such as self-description, flexibility and extensibility, and is widely applied in the description, storage and transmission of meteorological data. Wind filed streamline demonstrates the direction and trend of wind to some extent. For visualization of wind field streamline using GRIB Meteorological data, GRIB data are firstly converted into grid data using inverse distance weighted interpolation method, and then this paper proposes an algorithm for determining and tracking the points on streamline by streamline vector value evaluation and direction detection. Finally, the chart of wind field streamline is drawn using real GRIB data. The results have proved that the designed algorithm is feasible and the chart meets the needs of users.
