![]() ![]() This causes air to blow from the water onto land, resulting in dry conditions because little or no rainfall is received. Little Rainfall on LandĪ land breeze can occur on land when there is a significant vertical pressure gradient between land and water. The collision of cold and hot causes thunderstorms. These winds collide with cold, dry air moving in from an area of low pressure. This hot spot acts as a pivot point for winds circling it. These winds often cause the air to come together in a system called a “ hot spot.” ThunderstormsĪs the land heats up, hot air rises and starts winds in the atmosphere. This process draws up cool air from the water and usually causes heavy mist or even fog, known as a sea or lake haze. Distinct Features and Characteristics of a Land Breeze High Humidity at Seaĭuring the day, land breezes bring a large amount of warm air from inland. ![]() The air over the ocean then flows onto the land to equalize the pressure. Because of this, it develops lower pressure than the sea. Since water has a higher specific heat capacity, the temperature of the land cools at a slower rate during the night than the seawater. This is because changing the temperature of land takes less energy than changing water.Ī land breeze is a warm air blowing off the land. Land heats and cools more quickly than water. Another example, such as in coastal areas, due to the temperature difference between land and sea during the day, the formation of sea breeze blowing toward the land Instead, it blows from land to sea at night.To understand what causes a land breeze, it’s crucial first to understand the difference in heating of both land and sea. Therefore, the wind blows from the valley to the mountain At night, the high mountain air cools faster, so the wind blows from the mountain to the deep valley. Because the tropics absorb more of the sun’s radiation, the atmospheric pressure difference leads to air flow and wind.Īs for local areas, For example, in high mountains and deep valleys, during the day, the air at the top of the mountains, heated by the sun, rises, and in the deep valleys, cold air takes its place. When solar radiation passes through the earth's atmosphere, the atmosphere absorbs about 2 x 10 16W of energy, a small part of which is converted into the kinetic energy of the air. The blades of wind turbine rotates 13 to 20 revolutions per minute, depending on their technology, at a constant or variable speed, in which the speed of the rotor changes relative to the wind speed to achieve higher efficiency. Wind turbine is a machine that converts wind energy into electric energy. At night, hillside due to radiation cooling, its cooling rate is faster than the same height of the air, cold air along the slope down into the valley, called mountain wind. The air in the valley replenishes the lost air up the hillside, and the wind that blows from the valley to the hillside is called the valley wind. This is due to the fact that during the day the mountain slopes are heated faster and the temperature is higher than that of the air at the same height above the valley, and the warm air on the slopes flows from the mountain slopes to the upper valley. The former is called valley wind, and the latter is called mountain wind. In mountainous areas, due to thermal reasons, the valley blows to the plain or hillside in the daytime, and the plain or hillside blows to the night. The temperature difference brings about the density and pressure difference of the near-surface atmosphere, and the pressure gradient force pushes the air flow from regions of high pressure (low temperature) to regions of low pressure (high temperature).Īt night (winter), the situation is reversed, with low-level winds blowing from the continent to the ocean, known as land winds. That is, the temperature over the sea is lower than the land during the day and higher than the land at night. Land and sea winds are caused by the temperature difference between land and sea during the alternation of day and night. ![]() Sea-land breeze is a diurnal local wind that occurs in offshore and coastal areas. ![]()
