The image is a wind direction map of Windrichting Belgium. It is a circular map with a green background and a red center in the center. The map is divided into six sections, each representing a different wind direction. 

The top section of the map shows the wind direction in different directions, with the north and south sections labeled NW, NW, NNO, NO, ONO, WZW, ZZW and ZZO. The north section shows the direction of the wind, while the south section shows that the wind is expected to move towards the north.

There are also several lines connecting the different directions in the map, indicating the direction in which the winds will move. The lines are labeled with the names of the winds, such as "NW", "NNO", "NO", and "ONO". The map also has a legend at the bottom that explains the meaning of each line.
