During a sunny day along a coastline, differential solar heating causes a local circulation pattern known as a sea breeze to develop. In what sequence do the following stages occur, starting from initial solar heating to the resulting coastal wind?
- 1Solar radiation heats the coastal land surface faster than the adjacent ocean water.
- 2The air directly above the warmed land expands, becomes less dense, and rises.
- 3A localized area of lower atmospheric pressure develops at the land surface.
- 4Cooler, denser air over the water flows inland toward the lower pressure over land.
Answer
Solar radiation heats coastal land faster than ocean water, causing the air above land to warm and rise, which forms a local low-pressure zone that draws cooler, denser marine air inland.
During daylight hours, solar energy warms the land faster than the adjacent ocean because land has a lower specific heat capacity. The air in contact with the warm ground heats up, expands, and ascends, creating a localized surface low-pressure area over the coast. Cooler and denser air situated over the water flows inland along the pressure gradient toward the lower pressure, forming a daytime sea breeze.
Step-by-Step Solution
Key Concept
Differential heating between land and water creates local pressure gradients that drive coastal sea breezes.
