What is an anticyclone?

atmospheric phenomena over the centuries have been the object of study because of its importance and impact on all spheres of life.Cyclones and anticyclones are no exception.The concept of these weather phenomena gives in school geography.Cyclones and anticyclones, after this brief study for many remains a mystery.Air masses and fronts are key concepts that will help display the essence of these weather events.

air mass is often the case that for many thousands of kilometers in the horizontal direction of the air have very similar properties.This mass is called Air.

Air masses are divided into cold, warm, and local:

- called cold mass, if the temperature is lower than the temperature of the surface on which it is located;

- warm - it's such an air mass at a temperature higher than the temperature of the surface that is below it;

- local air mass temperature is the same as it is under the surface.

air masses are formed over different parts of the Earth, which leads to features in their properties.If the mass is formed over the Arctic, then, accordingly, it will be called the Arctic.Of course, this air is very cold, it can bring light fog or haze.Polar air finds its deposit temperate latitudes.Its properties can vary depending on what time of year occurred.In the winter the polar masses are not much different from the Arctic, but in the summer so the air can bring very poor visibility.

Tropical masses came from the tropics and subtropics, are hot and dusty.They are the originators of the haze which covered items, if you look at them from a distance.Tropical masses formed on the continental tropical lead to dust whirlwinds, storms and tornadoes.Equatorial air is very similar to the rain, but these properties are more pronounced.

fronts

If two air masses having different temperatures meet, formed a new weather phenomenon - the front or interface.

By the nature of the front divided into stationary and mobile.

Each existing share the front air masses.For example, the main polar front is imaginary mediator between polar and tropical air, the main Arctic - between the Arctic and the Arctic, and so on.

If warm air mass creeps on the cold, there is a warm front.For travelers, the entrance to the front of this could presage a heavy rain or snow, which will significantly reduce visibility.When cold air is wedged under a warm, there is the formation of a cold front.Ships falling within the area of ​​the cold front, suffer from squalls, rain and thunderstorms.

It so happens that the air masses do not face, and catching up with one another.In such cases, occluded front is formed.If the role of catch-up performs a cold mass, a phenomenon referred to as the cold front occlusion, if on the contrary, it is a warm front occlusion.These fronts are storm weather with strong gusts of wind.

Cyclones

To understand what anticyclone, it should be understood that such a cyclone.This region of reduced pressure in an atmosphere with a minimum index at the center.His rise to two air streams having different temperatures.Very favorable conditions for their formation are in the front.In the cyclone the air moves from the edge, where the pressure is higher, the center of the low pressure.In the center of the air as if it is thrown up, which allows the formation of updrafts.

From the way the air moves in a cyclone, it is easy to determine in what hemisphere it was formed.If it coincides with the direction of clockwise, then this is definitely the southern hemisphere, if - against this northern hemisphere.

Cyclones provoke such weather phenomena as congestion cloud masses, heavy precipitation, wind and temperature fluctuations.

Tropical Cyclone

cyclone formed in the temperate latitudes, separated by cyclones that its origin is to the tropics.They have many names.This hurricanes (West Indies), and typhoons (East Asia), and simple cyclones (Indian Ocean), and Arch (South Indian Ocean).The size of such vortex range from 100 to 300 miles, and the diameter of the center - from 20 to 30 miles.Wind

then accelerates to 100 km / h, and it is typical for the entire region of the vortex that radically distinguishes them from cyclones formed in the temperate latitudes.

sure sign of the approaching cyclone is a ripple on the water.And it goes in the opposite direction the wind is blowing and the wind that blew shortly before.

Anticiklon

Area of ​​high pressure in the atmosphere, with a maximum in the center - this is an anticyclone.Pressure at its lower edges, allowing air to rush from the center to the periphery.The air trapped in the center, and the odds are constantly coming down to the edge of the anticyclone.So formed downdrafts.

anticyclone is the opposite of the cyclone is also because in the Northern Hemisphere, he follows the clockwise in the Southern goes against it.

After reading all the above information, we can say that this anticyclone.

interesting feature of anticyclones in temperate latitudes is that they seem to pursue cyclones.In this case, it is characterized by slow-moving state of the anticyclone.Weather, formed this vortex, cloudless and dry.Wind practically not observed.

Asian anticyclone

second name for this phenomenon - Siberian high.The duration of his life - about 5 months, and it is late autumn (November) - the beginning of spring (March).This is not one anticyclone, and a few that rarely give way to cyclones.The height of the wind reaches 3 km.

Due to the geographic environment (mountains of Asia) cold air can not separate, which leads to greater heat dissipation, the temperature near the surface drops to 60 degrees below zero.

Talking about what anticyclone, we can confidently say that this atmospheric vortex of enormous size, bringing clear weather without precipitation.

cyclones and anticyclones.Similarities and differences

In order to understand better what is an anticyclone and a cyclone, you need to compare them.Definitions and main aspects of these phenomena we found.It remains an open question whether the differences between the cyclones and anticyclones.The table shows the difference more clearly.

Thus, we can see the differences between the cyclones and anticyclones.The table shows that this is not just the opposite, the nature of their origin is completely different.
