Land breeze blows during _________ a. Summer b. Winter c. Day d. Night
Hint: Land breeze, an area wind system characterized by a result land to water late in the dead of night. The land breeze is usually shallower than the ocean breeze since the cooling of the atmosphere over land is confined to a shallower layer in the dark than the heating of the air during the day. The air over the ocean is now warmer than the air over the land. The land loses heat quickly after the sun goes down and also the air above it cools too. This causes a little gradient between the ocean surface and also the nearby land in the dead of night and therefore the wind will blow from the land to the ocean creating the land breeze.
Complete answer: > SUMMER: This breeze occurs most frequently within the spring and summer months due to the greater temperature differences between the ocean and nearby land but land breeze can occur in winter also . So, this selection is wrong. > WINTER: Land breeze can occur in winter also as land gets heated in winter also but cools more quickly. Hence, this feature is additionally incorrect. > DAY: During the day, the sun heats up both the ocean surface and also the land. The wind will blow from the upper pressure over the water to lower pressure over the land causing the ocean breeze. Thereby, this feature is additionally incorrect. > NIGHT: It's a well-known proven fact that land takes a very long time to heat up. At day the land gets heat up more quickly and at night-time the land cools more quickly. So in the dark the air expands up causing the breeze to result in land. Hence, this feature is correct.
Our required answer is d that's night.
Note: The land gets heated by the sun, much faster than the water during daytime. This heats up the air over the land and it expands and hence the new air rises up and creates a vacuum. And hence the cool air moves from the land to the ocean and is thought to be because of the land breeze. Land breezes cause the environment to cool down causing the temperature to lower down.
