Wind is an uncontrollable phenomenon that can cause serious destruction and damage, a person can only tentatively predict its direction and speed. Wind rose is a meteorological concept that characterizes the direction, speed and strength of the wind in a particular region, observed over a long period of time.

The wind rose diagram is built individually for each region using averaged data for different periods of the year. These data play an important role in the construction of airfields and in the planning of residential quarters. Knowing the strength and speed of the wind makes it possible to timely determine the risk of a dust storm or dry wind. Recently, these wind roses are especially relevant, as they help to choose the most optimal place for the installation of wind power plants. It should be noted that the wind is monitored throughout the year.

Compass rose in meteorology

The main purpose of the wind rose is to determine the frequency of the air flow, the direction and nature of the wind. For example, when creating a runway, knowledge of the flow and direction of the wind helps to simplify the takeoff and landing of aircraft. The graphic image of the rose is known to many and can be seen on NATO symbols or take-off and landing maps, as well as on meteorological sites. You can build a wind rose yourself, recording data on the wind direction every day for several months.

In meteorology, there is a wind classification based on its strength (speed):

• weak wind - speed 2-3 m / s;
• moderate - 4-7 m / s;
• strong - 10-12 m / s;
• storm - more than 15 m / s;
• storm - more than 20 m / s;
• hurricane - 30 m / sec.

Since the wind is not constant, short periods of time are taken into account when making a weather forecast.   The weather in Moscow  , taking into account the wind rose, makes it possible to timely identify the threat of a storm warning for a particular area. This factor is also taken into account when assessing the temperature regime of a particular region.

It should be noted that knowledge of the average annual value of the direction and strength of the wind is necessary when building country and country houses and planning personal plots.

Defining a wind rose

To construct a diagram, rumba are used (the corners of a circle that make up 1/32 of the circle of the horizon). In meteorology, two coordinate axes and 16 points are used; for personal use, you can compose a wind rose in 8 points, each of which corresponds to the north, northeast, east, south, southeast, southwest, west and northwest. To the resulting corners, it is necessary to construct bisectors, to set aside equal segments connected by lines. As a result, you should have four coordinate axes, each of which will correspond to the cardinal points. Subsequently, the results of meteorological data on the strength and direction of the wind are plotted on the obtained axes. Such a chart can be built by month, quarter or year. To build a wind rose, you can use MS Excel charts.

Wind speed and comfort

Calculation of the wind rose is especially relevant during periods of extreme cold and excessive heat. It is these periods that are the most dangerous for humans, which is associated with the development and spread of pathogens and the deterioration of the ecological state of the environment.

Long-term observation of the wind helps to determine the rationality of land use and prepare the population for various natural disasters. The weather in Krasnodar  , taking into account the wind rose, allows you to timely prepare for dry summer periods. The wind rose is also relevant in the northern regions, where snow storms are often observed. Residential buildings, planned and erected according to the wind rose diagram, contribute to the comfortable living of the population in such conditions, protecting them from the effects of strong winds.

The best protection against frequent and strong prevailing winds is multi-section high-rise apartment buildings located across the wind direction. The choice of the type of residential buildings, their location and the distance between them are determined by the architects on the basis of the same wind rose map.
