Question

Difference between sea and land breeze in points

Answer 1

Answer:

Land breezes come from land while sea breezes come from the ocean or other large bodies of water. The key difference is due to the property of water to retain heat and warm up longer as compared to land. Land breezes are also known as off-shore winds while sea breezes are also called on-shore winds.

Answer 2

Answer:

Land breeze and sea breezes take place near bodies of water. The key difference between the two is caused by the property of water to retain and warm up longer. The differences in the temperature of land and water causes respective changes to the densities of the air above them. The resulting low pressures then cause alternating air movements which are manifested as breezes. Individuals situated near coastlines (within 50 kilometers from the oceanfront) experience cool sea breezes during the day and warm land breezes at night. Furthermore, these winds are instrumental in humidity and temperature levels, and precipitation rates.

Difference Between Land Breeze and Sea Breeze

What is a Land Breeze?

As it name suggests, the local wind system which occurs from land to water is called land breeze and some refer to it as an offshore wind. It arises at night and early morning when the land has a lower heat capacity as compared to the adjacent water. Particularly, land breezes last longer during the last weeks of summer as this is when the sea temperature will gradually increase to the land’s daily temperature variations.

The following occurrences outline how land breeze is formed:

• Late at night, the loss of heat source causes land to quickly cool down which causes the heat to be released towards the surrounding air.
• As compared to land, water retains heat longer which causes the air above it to have lesser density and rise.
• Low pressure is formed above the water while high pressure is formed above the land.
• The denser air above the land moves to the space over the water.
• As winds typically blow from high to low pressure areas, the cooler breeze then comes from the shore and is now called as “land breeze”.

Difference Between Land Breeze and Sea Breeze:

What Is a Sea Breeze?

Winds that blow from large bodies of water specifically seas and oceans are called sea breezes and some refer to them as onshore winds. Generally, they occur more frequently during the spring and summer seasons due to the more apparent temperature differences between the water and adjacent land. This is most often observed in the afternoons when the nearby land has been heated at its maximum level. Notably, sea breezes are stronger during summer months as compared to winter season. This is again attributed to the huge temperature difference between land and sea which may even prompt thunderstorms which are essential in bringing rain. Hence, sea breezes are not that apparent during autumn and winter months because the temperature differentials are smaller.

The following occurrences outline how sea breeze is formed:

• During day time, the sun often quickly heats up land.
• The air above the land gets warmer than the air above water.
• As the air above land is warmer, it gets less dense and it begins to rise.
• Low pressure is formed.
• The denser air above the water moves to the space above the land. This cooler air is now what is termed as a “sea breeze”.
