Is it possible to detect Coriolis effect using a Wind Rose?
Yes, your figure is correct: in the mid-latitudes we have cyclones and anticyclones. They can't exist on equator because the Coriolis force there is too small to keep them stable. But the cyclones or anticyclones are present all around your country and their effect cancels each other. So, you can't determine the presence of Coriolis force. Otherwise, the effect of spining anticyclones and cyclones isn't specific to your country, but is (as previously stated) present over mid-latitudes. Also, the Coriolis effect isn't acting on microswirls because the Coriolis parameter is so small (due to too slow Earth's rotation).
