Wind direction.

determine the wind direction and strength - a pretty standard problem in meteorology.These settings affect the perceived temperature, as well as the weather itself - because the winds carry large air masses.From leading weather can often hear that somewhere are large cyclones or anticyclones from the Arctic or, for example, on the Atlantic side.Wind - is the movement of air masses in the lower atmosphere from the high to low pressure, so that the difference from strong indicator of pressure in close areas depends on the wind force.That is why hurricanes and typhoons rarely occur in the interior of the continent.But near the coast or the ocean - much more often.Calm, that is calm, there is where the pressure is the same in the related fields.But this situation is not very common.

of the prevailing wind direction, especially its speed and force gusts, it is very important for air traffic controllers.When strong winds the pilot will need to make this correction, and if the wind is too strong, may even have to cancel or postpone the flight.Same thing with the ships.Even on the boat wind strength and direction are important.That's why meteorologists record wind speed and direction with the help of special devices, and then even make a special schedule, a wind rose, showing the wind which direction is predominant in a particular place.Usually, the wind rose compiled at the end of the year or even a longer period.For example, the prevailing wind direction in Moscow in recent years - the south-west.That is most of the time it was blowing south or west wind.

way, when talking about the wind direction, the designation of parts of the world is of particular importance.If the wind is said to be the south, then it blows from the south.So, some confusion arises when people see the arrow direction from left to right and believe that east wind.No mistake there!In the case of determining the wind arrows always indicate the direction from which the wind is blowing, but not much.Why is it so happened, to tell difficult, so it happened.

So how do you determine the wind direction?Easily!Mankind has invented several devices designed to make it quick: anemometer to be used in courts, vane, which helps determine the direction and strength of the wind, even at home, as well as special wind indicator, which can often be seen at airports: they are in the form of a long orange-whitesimilarity net.

Wind power is usually defined along with its direction, it is often indicated in points or meters per second.Sometimes, when the exact figures are not important, the terms "moderate", "weak" and so on.

In addition, there are seasonal winds, as well as those whose direction depends on the time of day - usually observed on the coast of the sea or other large bodies of water.It is a breeze and the monsoons.They have a major effect on climate and weather in cities and villages, located not only near large bodies of water, but also in the interior of the continent.

Thus, wind direction and strength - these are some of the key weather and climate parameters, along with temperature, pressure and precipitation.
