Summer phenomena of nature

When the calendar summer begins is known to everyone, but when does it start from a biological point of view or naturalistic?

In science, it is commonly believed that the summer begins during the summer solstice. which falls on June 20-21. The longest day and the shortest night, with which the reverse day-time report starts.

The most common natural phenomena in the summer:

The weather is excellent. All natural phenomena are favorable. Bright sun, light air clouds often turn under the influence of heat into cumulus and rain. Falling very low above the horizon, they often irrigate the earth with warm rains that promote the growth of abundant vegetation.

Summer rains. as a rule, short-term. Among the most frequent on the territory of Russia, it is possible to encounter severe rains, storm and mushroom rains. The gradation is relative, the basis of the classification can be the principle of intensity and time interval.

Often one can see such a natural phenomenon

characteristic of this time as a summer storm. At a certain confluence of factors, when a strong wind drives cumulus clouds and the air is filled with electrical voltage, lightning arises accompanied by a thunder. Thunderstorm often has terrible companions.

Together with the thunderstorm, torrential rains, strong storm winds and even hail can occur. The latter phenomenon – a kind of nonsense. In summer, in hot, hot weather, large spherical ice particles pour down from the sky to the earth. Their size can be very different: from one millimeter to large blocks with a kilogram of weight. They fall only from cumulus clouds of black color. The whole bacchanalia lasts about fifteen minutes, but the consequences are sometimes very serious. Suffer crops, the future crop dies.

After a thunderstorm, it is often possible to see such a phenomenon of nature – a rainbow. This is not an atmospheric, but an optical phenomenon, showing how sunlight can be refracted, reflected in the seven-color spectrum. Rainbow can be seen and in the constant spray of the fountain. It shimmers, creating the illusion of

an unreal picture.

Rosa is the first harbinger of the fact that the summer ends. It falls into the pre-dawn hours in the form of small drops that settle on the stems and foliage of plants. At night, the temperature drops sharply, moisture rises above the ground and condenses in the form of water droplets. It is impossible to overestimate the value of dew. It helps to fill plants with life-giving moisture, to saturate them with the necessary energy.

The transition to autumn is the harvest season. Hot season, but very joyful. The end of August – the beginning of a decrease in temperatures, rains are increasingly beginning to go, which are getting colder and colder. Lime is the first plant that discards leaves, and from that moment on autumn falls into its legal rights. The days become shorter. Birds gather in flocks and slowly begin to leave their homes. The air is filled with a certain freshness, in which precursors of swift outbreaks are felt. Weather phenomena suggest how soon they will not be replaced by others.
