Hi,

thank you very much for your post, but it unfortunately didn't answer my questions :/

(1) I already knew that the wind is moving into the low, but I didn't understand why. Picture 2 shows clearly that the wind turned to the left. But why? When I imagine the wind and therefore the Coriolis becoming smaller because of the friction force, the long arrow (pressure gradient force) should move the tail of the arrow up -> so the wind should turn to the RIGHT. The Do you understand what I mean?

(2) Is the Coriolis opposing the pressure gradient (like in picture 1) or is it perpendicular to the pressure gradient, like in the video ?(https://www.youtube.com/watch?v=7zSN18isTYk) The video is called surface wind direction (no friction) so I thought it is without friction

Best,
