Detailed explanation-1: -Upwelling also happens as a part of El Niño (ENSO) events in the Pacific Ocean off the coast of Ecuador and Peru and this has far-reaching effects on weather, changing precipitation patterns in many areas of the world.
Detailed explanation-2: -This study shows that intense upwelling systems exist along the major western boundary currents (WBCs) around the global ocean.
Detailed explanation-3: -Winds blowing across the ocean surface often push water away from an area. When this occurs, water rises up from beneath the surface to replace the diverging surface water. This process is known as upwelling.
Detailed explanation-4: -While there is thermohaline forcing in all oceans, and undoubtedly upwelling as a result of the global thermohaline forcing, there are no deep water sources in the North Pacific and the intermediate water sources are weak.
