During summer, you feel relief near a lake because the air above the water is cooler due to the lake’s slower heating and cooling process compared to land. This cooler air, along with the breeze, helps to cool down the surrounding area, providing a welcome respite from the heat.
Here’s a more detailed explanation:
Slower heating and cooling:
Water has a higher heat capacity than land, meaning it takes more energy to raise its temperature. Therefore, during the day, the lake heats up more slowly than the surrounding land, and at night, it cools down more slowly.
Evaporation:
As the water evaporates from the lake’s surface, it takes heat with it, further cooling the water and the air above.
Air pressure differences:
During the day, the land heats up, creating a low-pressure zone. The cooler, high-pressure air above the lake then moves towards the land, creating a refreshing breeze.
Sea/lake breeze:
This phenomenon, known as a sea or lake breeze, carries the cooler air from the water body inland, providing a cooler and more comfortable environment.
