Summary
These notes cover the formation of mid-latitude cyclones, gyres, and the interaction between ocean currents and wind directions. The document details the Coriolis effect, which deflects water currents to the right in the Northern Hemisphere, and to the left in the Southern Hemisphere. It further explains how these currents are impacted by other factors.
