By mid-afternoon a wind whips up off the water, the air becomes cooler, and large, towering cumulus clouds menace the skies inland from the beach. The strength of the sea breeze depends on the difference in temperature between the land and ocean. A sea breeze is caused by the difference in temperature between the landmass and the ocean. Since the surface flow of the sea breeze terminates over land, a region of low-level air convergence is produced. Sea breezes alternate with land breezes along the coastal regions of oceans or large lakes in the absence of a strong large-scale wind system during periods of strong daytime heating or nighttime cooling. In addition to these points, the land breezes usually occur during the night, and contrary to that, sea breezes are formed during the daytime. The much cooler air just above the ocean surface creates an area of higher pressure. Updates? Which statement is true of sea … On a hot and sunny day, the landmass heats up much quicker than the ocean water causing slightly lower pressure. As such, sea breezes are more localised than prevailing winds. Sea breezes alternate with land breezes along the coastal regions of oceans or large lakes in the absence of a strong large-scale wind system during periods of strong daytime heating or nighttime cooling.
