In this study, detailed surface meteorological and vertical profile features about sea and land breezes in the Seoul Metropolitan Area (SMA) were investigated using the data from urban meteorological observation system in SMA (UMS-Seoul). Land breezes influence the weather, particularly when a strong change of wind direction occurs at night.Local circulation plays an important role in producing high-resolution meteorological and air quality information. Sea breezes are not often observed during winter. The temperature might remain the same when the land breeze occurs. Sea breeze tends to decrease the air temperature. Sea breezes are stronger than land breezes due to the bigger temperature difference.ĭue to temperature differences, land breezes are weaker when compared to the sea breeze. The sea breeze is deeper when compared to the land breeze.Ĭooling of the air over land typically occurs within a shallower layer at night, the land breeze is shallower when compared to the sea breeze. The sea breeze contains more amount of moisture due to the particles absorbed from the water bodies. Land breezes’ pace span from 5 to 8 knots. Sea breezes’ pace span from 10 to 20 knots. Land breezes are most common in autumn and winter due to the cooler nights. Sea breezes are more often experienced during spring and summer because of the significant temperature differences between land and water. When winds blow from high to low-pressure areas, the cool breeze that comes from the shore is what is referred to as a land breeze. When the denser air above the water moves to space above the land it is known as the sea breeze It then continues into the initial hours of the morning until the heating of the day begins. It arises at the dead of the night when the sea surface is warmer than the adjacent land because the land having a lower heat capacity and cooling off faster. It allows moisture within the air What Is Land Breeze?Ī land breeze could be a local nighttime and early morning wind that happens along coasts and blows from the land bent on the ocean. It can trigger thunderstorms especially when the air carries moisture and is unstable. Sea breeze brings relief from the oppressive weather condition. The magnitude of the sea breeze will vary counting on the change in temperature from the land and ocean. The wind will blow from the upper pressure over the water to lower pressure over the land causing the Sea Breeze. To compensate, the air will yield to the ocean. High surface pressure from the water will form due to the colder air. The nice and cozy air over the land will rise throughout the day, increasing pressure at the surface.
However, water changes the temperature up way more slowly than land, and so, the air above the land will be warmer compared to the air over the ocean. The land takes much of the sun’s energy likewise. Water is often known as a decent absorber of the energy from the sun. In the daytime, the sun changes the temperature warmer on both the ocean surface and land. A sea breeze is occurred during the spring and summer months due to the higher temperature difference between the ocean and nearby land, particularly within the afternoon when the land is at maximum heating from the sun. It’s been developed because of differences in air pressure created by the changing heat capacities of water and dry land. You can check about convection from this article Difference Between Conduction Convection and Radiation What is a Sea Breeze?Ī sea breeze will be described as a coastal local wind that blows from the ocean to the land.
However, in this article, let us also study the Difference Between Sea Breeze and Land Breeze Both these breezes have some similarities. When the breeze flows from the sea towards the land, it is the sea breeze. When the breeze flows from the land towards the sea, it is a land breeze.
We can thus categorize the breeze into two types, land breeze, and sea breeze. The convection phenomenon is involved in the land breeze and the sea breeze. This leads to a land breeze and the sea breeze that occur near the water bodies. Thus, sand gets hotter than the water or the sea. But the sand absorbs the sun’s heat at a faster pace than water. During the day, the sun warms up the land or sand as well as water. Sea breeze and land breeze how are they different.
