The small flags appearing in the weather forecast represent several winds.
In the weather forecast, the wind direction is indicated by eight directions. The short straight line and small triangle above represent the wind speed and are perpendicular to the left side of the wind pole. Relatively long short straight lines are long strokes, and each long stroke represents the wind of 4m/s, which is the secondary wind in our forecast. The short stroke is about half of the long stroke, representing the wind of 2m/s, that is, the first-class wind.
For the little flag you mentioned, each pennant represents the wind of 20 meters per second, which is equivalent to 8 ~ 9 grades.
