Sea Breeze And Land Breeze

During summers, if you go to a beach...

You experience a nice, cool breeze blowing on the land during the afternoon.

This cool breeze flowing from sea to land is called Sea Breeze

Sea breeze is caused because water and land have different heating abilities.

Water takes more time to warm up than land or earth's surface, so the land heats up easily as compared to water.

Water also retains heat longer than land. That means land cools down easily when compared to water.

This different heating of water and land causes two kinds of winds to flow along coastal areas

The two types of winds or breezes are - Sea Breeze and Land Breeze

Let us study about sea breeze.

During the day time, when the sun is up, the land heats up and becomes warmer very quickly whereas water doesn't and stays cooler

Because of this, the air above the land also warms up a lot more than the air over the water.

The warm air over the land is less dense, therefore, it begins to rise up creating a void over the land, thus creating an area of low pressure over the land.

In the meanwhile, the air above the water stays cooler. This cooler air is in a high-pressure zone and it tries to flow towards the land which is a low-pressure zone.

Due to this pressure difference, cold air over the water surface starts moving towards the land, until the pressure is balanced.

The cool air that flows from sea to land is called sea breeze.

This is why we find cool winds and lower temperature on beaches even on sunny days.

Now let us have a look at Land Breeze.

At night, the land quickly loses its heat while water retains its warmth.

This means the air over the water is warmer, therefore less dense and thus begins to rise

This time low pressure is created over the water whereas relatively high pressure is created over the land

Due to this pressure difference, cold and dense air over the land begins to move to the water surface to replace the warmer rising air.

This cool breeze or air blowing from the land towards the water is known as a land breeze

Revision

See breeze and land breeze occur along coastal areas or areas with adjacent large water bodies due to different heating abilities of water and land.

Sea breezes are the cool winds flowing from the cooler sea to the warmer land. Sea breezes only occur during the day time.

Land breezes are the cool winds flowing from the cooler land to the warmer sea. Land breezes only occur during the night time.

Sea breezes are the cool winds flowing from the cooler sea to the warmer land. Sea breezes only occur during the day time.

Sea Breeze - Winds from sea to land. Only occur at day time

Land Breeze - Winds from Land to Sea. Only occur at night time
