The wind is moving all over the planet, and in every part of the world it has its own unique name. So what determines its direction? Why does it move in one direction during the day, and at night changes its direction in the opposite direction? These issues will be discussed in more detail below.

Types of winds and their origin

There are several types of winds.

Trade winds

The trade winds are a stream of dry air mass that appears due to sharp jumps in the temperature of atmospheric pressure at the equator and in the hemispheres of the planet. The trade winds appear exclusively in the tropical zone of the Earth. Such winds are classified as stable, that is, they are stable in temperature and moisture level. They play an important role in the process of forming a tropical climate.

Monsoon

Monsoons arise due to changes in the temperature of atmospheric pressure, which appear due to the difference in temperature. Monsoons go either from the side of the water to the shore, or vice versa.

In winter, the air flow goes towards the sea. This is due to the fact that the air above the sea surface is warmer than over land. In summer, monsoons go towards land, which is why precipitation occurs. Such winds are especially active in the tropical regions of the planet.

Sea breeze

The sea breeze is an air stream that in the daytime goes from the water side in the direction of the coast, and at night, on the contrary, from the land side in the direction of the sea. This phenomenon is characteristic of most of the sea coasts of the planet.. A breeze occurs due to the temperature difference between water and land. With a difference of at least three degrees, wind will form.

Bora

Bora is a choppy air stream coming from the north. Such a wind appears in places where the sea and mountains are located. Most often, the wind occurs in areas where there are small elevations and the seashore. Bora overcomes the mountain and heads down. In winter time, such air mass is cold, but in summer - warm.

There are many more different types of wind, the appearance of which is directly related to climate, temperature, atmospheric pressure, and other factors. These include zuid, norder, marshmallows, sirocco, samum, tornado, kalima, and others.

Interesting fact: in Greek mythology, Zephyr is the god of the west wind. Following the myths, Zephyr dominates the eastern Mediterranean. Such a wind is warm, but often accompanied by storms and thunderstorms.

There are also constant and seasonal winds. A constant airflow always moves with about one force in three to four points. It moves in one direction, occasionally deviating from the route. Seasonal winds include periodic flows, the direction of which varies depending on the seasonal period.

Why in the afternoon the wind blows from the sea towards the coast, and at night - vice versa?

As indicated above, the sea stream has a name - a breeze. Its direction changes twice a day: in the morning it goes from the sea, and closer to the evening - from the coast.

Interesting fact: On June 15, 2007, the European Wind Energy Association and the Wind Energy Council introduced Wind Day. Two years later, the event received the status of an international holiday.

A breeze appears when temperature deviates between land and water.In the morning and in the afternoon the sun heats the land, because of which its temperature increases significantly. However, air currents prevent the sun from heating the sea surface. Therefore, the heated air masses are directed towards the coast. In their place, new masses of cold, heavy air form.

After sunset, the situation changes: the water heated during the day remains warm for a long time, while the land cools down several times faster. That is, low atmospheric pressure is now above the sea. This causes a change in the direction of the breeze: in the evening, at night, it begins to blow towards the sea.

The sea breeze is divided into two categories: day and night. Daytime breeze blows from the sea to the shore, night - from the land to the water. Such a wind appears due to the difference in atmospheric pressure between the sea and land. In the daytime, the pressure level over land is lower than over water. Therefore, the breeze blows towards the shore. At night, the situation changes in the opposite direction: above land the pressure level is higher than above the sea. Because the breeze is directed from the coast to the sea.
