These air masses, called the Hadley Cell, rise near the equator and travel north and south, transporting heat and water towards the poles. The major patterns in atmospheric circulation around the tropics (from around latitudes of 30 o N to 30 oS) are the result of convection that occurs because areas around the equator receive more sunlight than higher latitudes (see absorption and reflection of sunlight). This transfer of heat because of density differences in air is called convection. Cooler air from above sinks, and air moves horizontally to replace the rising warm air, which we experience as wind over the surface of the Earth. Warmed air expands and becomes less dense than cool air, so warmed air near the surface of the Earth rises up.
This heat is absorbed and re-radiated by greenhouse gases in the atmosphere, resulting in the greenhouse effect. Sunlight absorbed by Earth’s surfaces is re-radiated as heat, warming the atmosphere from the bottom up. Most heat is transferred in the atmosphere by radiation and convection. Because air molecules are farther apart than they are in liquids or solids, they do not collide as frequently as in liquids and solids, and air is a poor conductor of heat. A small amount of heat in the first few centimeters of the atmosphere is transferred from the surface by conduction, the process of molecules colliding and transferring energy. Most of this absorption happens on Earth’s surfaces, which increases the temperature of both land and water. Solar radiation that reaches the Earth passes through the atmosphere and is either absorbed or reflected by the atmosphere and Earth’s surface. For example, a city like Mumbai has a lot of humidity and moisture in the air as it is situated near the sea.Illustration adapted from global circulations and jet stream pages The places or cities near the sea or around coastal regions generally have a humid and wet climate due to the effect of the sea breeze. Why is the climate of places near the sea have a humid climate?Īnswer. The sea breeze is strong enough and thus glider pilots take advantage of it to steer in higher altitudes. Which type of breeze is helpful for glider pilots?Īnswer. Hence, it is the reason for the occurrence of the land breeze and the sea breeze. The heavy and cooler ait flows towards the lighter and hotter air which in turn gives rise to the breeze. Thus, this makes the air above them lighter or heavy. The land and water have different heat absorption and heat retention capacity. What is the reason for the occurrence of land breeze and sea breeze?Īnswer. Whereas the inland places have a major temperature change.
Due to the breeze, the places near the sea or coastal areas do not have a lot of variation in the temperature.The land breeze is usually slower than the sea breeze and are generally weak.They both have an impact on the humidity levels, atmospheric temperature, and precipitation rates.Land breeze and sea breeze both occur near coastal areas.The wind contains more amount of moisture as it blows from the sea.Īfter studying the difference between land breeze and sea breeze, let us understand some more details. It remains the same during the land breeze. It occurs during the summer or spring season. It occurs during the winter or autumn season. It occurs during the nights or early mornings. The wind blowing from the sea towards the land is Sea breeze. The wind blowing from land towards the sea is Land breeze. The important difference between land breeze and sea breeze Parameter Difference Between Land Breeze and Sea Breeze It usually occurs during the summer days. As the name suggests, Sea breeze refers to the breeze or wind blowing from the sea towards the land. Thus, at this time, the sea air is cooler and heavy and it flows towards the land. What is Sea Breeze?ĭuring the day time, when the sun is up, the land air heats up faster whereas the sea air heats slowly. It usually occurs during the night or early morning when the land air is cooler than the sea air. As the name suggests, Land breeze refers to the breeze or wind blowing from the land towards the sea. Thus, the land air flows towards the sea. At this time, the land air is cooler than the sea air thereby creating a low pressure over the sea. Hence, after the sunset land or sand cools down before the water. The land heats up at a faster pace and so does it cool also. 3.1.1 FAQs about Land breeze and Sea breeze: What is Land Breeze?
