During the day, land heats faster than the sea, pulling cool air onshore. At night, the land cools faster, so the air flows offshore. This is called the sea-land breeze.
A new study in Nature Climate Change has reported that as the oceans become warmer, the sea-land breezes around coastal megacities are becoming weaker. In many locations, urban planners consider these breezes to be essential to cool urban areas and improve air quality, rendering coastal cities more liveable.
