From an astronomical point of view, it begins with the winter solstice around December 23 in the northern hemisphere and June 21 in the southern hemisphere, and ends with the spring equinox, around March 21 in the North and 21 September in the southern hemisphere, varying dates slightly according to year. The fact that the Earth's orbit is elliptical, results in one duration of less winter in the northern hemisphere and more regarding this in the South, since the Aphelion in July occurs during the austral winter, and January perihelion during the boreal. In short, winter lasts about 4 days longer in the southern hemisphere to the Northern.
From a meteorological perspective, on the other hand, are often considered winter the whole months of December, January and February in the northern hemisphere and June, July and August in the southern hemisphere.
Winter is the coldest season of the year, and its characteristics are inevitably defined in contrast to the other seasons of the year: since winter day temperatures are lower and there are fewer hours of sunlight. These characteristics are accentuated as we move away from the tropics and the polar circles, approaching.
In some regions of the planet, according to its latitude, altitude and weather conditions, you can see the snow fall.
In Greek mythology, Hades, God of the underworld, kidnaps the beautiful Persephone to be his wife. Zeus ordered Hades to return it and give it to Demeter, Goddess of the Earth and her mother. However, Hades cheats on Persephone and makes you eat pomegranate seeds, food of the underworld that forces her to stay there forever.

During the time that her daughter is with Hades, Demeter grieves and causes the autumn and winter.


2. Meaning of winter

Winter is one of four stations that happen during the year, running between the fall and spring. Between June 21 and September 21 develops in the southern hemisphere, while between December 21 and March 21 it does the same but in the northern hemisphere.
Winter is a word that has had an origin in the term latin hibernum and among its main characteristics are the following: that the days begin to become shorter, the nights are super long and the highlight is that temperatures are very low, below 10 ° and in some places on Earthmore than anything the more US away from the Ecuador, the same Iran becoming lower, reaching several degrees below zero.
For this reason is that humans must shelter us a lot whenever we leave home with covered, specially made sacks to withstand very low temperatures, scarves, gloves, hats, socks, because not to so inevitably will affect respiratory diseases that occur almost like an epidemic during this season of the year, especially as consequence that most of the places that it concurs or same where live remain closed almost all the time to avoid the entrance of the cold and the consequent cooling of the place.
Another solution against cold, in addition to shelter us with the costumes above turns out to be the use of electrical, gas or fire appliances, such as stoves, ventor calo, homes, salamanders, which allow to heat our environments in a very short time and allow us to not have to be emponchados in our home or work.

3. What is winter

Winter is one of the four seasons of the year, which starts in the so-called winter solstice and that concludes with the spring equinox. In the northern hemisphere, the Solstice takes place on 23 December, while in the southern hemisphere it occurs on June 21. At the beginning of the season, the days are shorter and nights longer, although the duration of the day is increasing as the season progresses.
Measurement of the winter by meteorologists is known as meteorological winter, and it measures the length of the station by patterns of climate sensitive, so the start of meteorological winter can vary depending on which is live so far North. Similarly, meteorologists are often classified as the three coldest months of the year, which are December, January and February in the northern hemisphere and June, July and August in the southern hemisphere winter. That said, the lowest temperatures of the year tend to sign up in January in the northern hemisphere and in July in the southern hemisphere.
Winter is closely related to frost and snow, while the snow only occurs in some regions of the world, while in the rest the only thing that manifests itself is cold. In some parts, the winter is also witness to a high rate of precipitation, causing a high rate of humidity in the environment due to the combination of the rain with cold temperatures.
By the harsh conditions, it is very common in winter for many animals to develop mechanisms that will help them survive the cold months. Some birds migrate to warmer places, while other species, such as frogs, snakes and bears, enters a State of hibernation that allows them to reduce their metabolic activity to a minimum, to be later reactivated when the weather becomes warmer.
