Little ovals on lines with , example, 36.06, numbers

[kr6ssy]

On the radar map that is included with my weather app, there are lines that change location when I hit the play button which represents future time. I think they represent wind lines. On these lines, there are little ovals that contain numbers, like 36.06. I hit play and the lines change and the numbers change. Just wondering where I can find info about this. The radar map says windy.com so that's why I came here. However, in settings, I cant get it to duplicate what is shown on my app.
