The Earth constantly rotates not only around its axis, but also around the Sun, which, together with the tilt of the planet’s axis, provides a change of seasons in the form and rhythm in which humanity is accustomed to observe this process. Seasons are replaced one after another, the maximum of solar energy receives one hemisphere, then another. For the month of December, a winter period is observed in the northern part of the planet with a minimum of light and heat, with shortened daylight hours up to the polar night, approaching the polar latitudes. At the same time, the southern hemisphere receives maximum light, here people enjoy the hot summer.
June creates the opposite situation - with its onset, winter comes in the southern hemisphere, and summer in the northern hemisphere. What interesting can you tell about the warm season, knowing all the features of the changing seasons?
What can surprise summer?
Most of the inhabitants of the northern hemisphere associate the summer months with vacations, fine weather, and relaxation. But in the southern hemisphere, summer for the above reasons begins from December and lasts until February, which forces us to organize life differently. The bulk of humanity still lives in the northern hemisphere, so for the vast majority of people, summer is associated with June, July and August. But it is certainly not associated with a favorable season, rest and good weather, because for southern, arid regions, relief to local residents comes precisely with the coolness of autumn and winter.People are waiting for winter and rains to take a break from the heat, to do agricultural work.
Indeed, in some places the summer temperature reaches 50 degrees, even exceeds this indicator. And already at 40 degrees heat, the human body releases up to a liter of sweat every hourforcing to drink water continuously. If the temperature rises to 71 degrees of heat, a person is able to tolerate the extreme indicator relatively normally for no more than an hour. Men more easily tolerate heat, women have a harder time - they have more subcutaneous fat, which prevents the body from cooling rapidly.
Other summer facts
A lot of interesting things can be said about the warm period. After all, there are places where there is virtually no summer - we are talking about the Arctic. But here and in Antarctica there is a polar day when the Sun does not hide behind the horizon for up to 6 months - that is how much it shines at the poles. Local plants and animals have adapted perfectly to the cold summer, many of them manage to breed offspring or pepper, give seeds for a couple of relatively warm, round the clock bright months.
It is worth pointing out the following facts:
- The longest summer day is fixed on June 21 and is called the summer solstice. Many pagan cultures celebrated this day;
- The highest summer temperatures are observed in Death Valley (California) - the temperature rises to 57 degrees above zero;
- Heat is tolerated in different ways by a person at different moisture indicators. Therefore, weather forecasters are actively using the so-called “heat index”, which takes into account both relevant indicators, both temperature and humidity;
- Hurricanes and thunderstorms manifest themselves in most cases precisely in the summer - warm weather creates optimal conditions for their nucleation and development.
Summer is especially time for all residents of the Northern Hemisphere. Especially for Russians and Europeans, living mainly in temperate climates, dreaming of warmth, the possibility of relaxation in good weather. After all, northerners need to have time to fill the body with vitamins, restore immunity in order to prepare again for winter and solar deficiency.
