What region of the ocean get the greatest input of solar radiation when it's winter in the northern hemisphere?

During winter in the Northern Hemisphere, the region of the ocean that receives the greatest input of solar radiation is the Southern Hemisphere, particularly around the equator and in the tropical regions. This is because these areas are tilted towards the sun during the Northern Hemisphere's winter months. Consequently, the Southern Ocean and surrounding tropical waters experience heightened solar exposure, while the Northern Hemisphere regions receive less direct sunlight.
