Which mechanism causes cyclonic rotation in low-pressure weather systems in the Northern Hemisphere?

💡 Explanation

When air flows towards a low-pressure zone, the Coriolis effect deflects it to the right in the Northern Hemisphere because the apparent force arises from Earth’s rotation, generating a cyclonic, counterclockwise rotation. Therefore, the Coriolis effect is key, rather than trade winds convergence, radiative cooling, or thermal expansion, which influence air mass stability and temperature.
