The Earth is tilted at an angle of 23°27` (23 degrees 27 minutes) to the plane of its orbit, so that different latitudes on Earth are directly oriented towards the sun as the Earth moves in its orbit. It is this variation that mainly produces the seasons. When it is winter in the northern hemisphere, the southern hemisphere faces the sun more directly and therefore experiences warmer temperatures than the northern hemisphere. Differences in temperature, climate and weather between seasons. The day at the winter solstice is the shortest of the year and the night is the longest. Beginning of winter in the Hindu calendar. Also called hemant. Some annuals never survive the winter. Other annuals need winter cold to complete their life cycle; This is called vernalization. As for perennials, many small ones benefit from the insulating effect of snow by burying them in them. Larger plants, especially deciduous trees, usually leave their upper part to rest, but their roots are still protected by the snow cover. Only a few plants bloom in winter, an exception is the flowering plum, which blooms in time for Chinese New Year.
The process by which plants get used to cold is called hardening. The astronomical calendar determines the seasons based on the 23.5-degree tilt of the Earth`s axis of rotation relative to its orbit around the sun. Both the equinox and solstice refer to the Earth`s orbit around the sun. However, the dates of the equinox and solstice are not fixed due to the elliptical orbit of the Earth to the Sun. Other animals begin to hibernate in winter and spend much of the season in a state of close sleep. Because many plants die or rest, animals can accumulate food to help them through winter periods, according to the World Atlas. The polar regions experience seasonal fluctuations, although they are generally colder than elsewhere on Earth. Near the poles, the amount of daylight changes drastically between summer and winter. In Barrow, Alaska, the northernmost city in the United States, it remains light all day between mid-May and early August. The city is in total darkness between mid-November and January.
During winter in both hemispheres, the low altitude of the sun causes sunlight to hit the Earth at an oblique angle. Thus, a smaller amount of solar radiation per unit area hits the earth. In addition, light must travel a longer distance through the atmosphere so that the atmosphere can dissipate more heat. Compared to these effects, the effect of changes in distance from the Earth to the Sun (due to the Earth`s elliptical orbit) is negligible. For many people, winter symbolizes many things and has been used by artists of all mediums to represent different things. Some use winter to indicate death, as in Robert Frost`s Stopping by Woods on a Snowy Evening. Some use it to indicate the absence of hope, as in C. S. Lewis` The Lion, the Witch and the Wardrobe, where it was always winter but never Christmas.
Winter is a concert in Vivaldi`s “The Four Seasons”; And there are many examples of four paintings, all depicting the same scene in different seasons. Ursula K. LeGuin`s novel, The Left Hand of Darkness, is set on a planet called Winter. In Alex Raymond`s Flash Gordon comic, there`s a land called Frigia, where it`s always winter. The land of Frigia can also be seen in the Flash Gordon series Conquers the Universe. Other uses of winter in graphic art can be found in Winsor McCay`s Little Nemo in Slumberland. There are many films in which a winter setting plays an important role, Fargo is an example. In addition, novels like Ethan Frome also use a winter setting to reflect the dark and frozen feelings of the characters. At the time of the winter solstice, the corresponding pole is about 23.5 degrees from the sun, according to NWS (opens in a new window). On this day, in the northern hemisphere, the North Pole is farther from the heat-producing star, while the southern hemisphere, which experiences summer, is closer. In order to survive the harsh winter, many animals have developed different behavioral and morphological adaptations for wintering: In the northern hemisphere, some authorities define winter time according to astronomical fixed points (i.e. only on the basis of the position of the Earth in its orbit around the sun), regardless of weather conditions.
In one version of this definition, winter begins with the winter solstice and ends with the March equinox.  These dates are slightly later than those used to define the beginning and end of meteorological winter – they are generally thought to include all the months of December, January and February in the Northern Hemisphere and June, July and August in the Southern Hemisphere.   Cold winters can quickly lead to life-threatening conditions such as hypothermia. Hypothermia occurs when a person`s body temperature drops below 95°F (35°C), according to the Mayo Clinic (opens in a new tab). Cold temperatures and wind chills can cause a person`s body temperature to drop within minutes. The inclination of the Earth`s axis relative to its orbital plane has dramatic effects on time. The widespread belief that winter is caused by the Earth being farther from the sun than in summer is not true. In fact, winter occurs in the Northern Hemisphere when the Earth is closest to the sun. “Function and underlying mechanisms of seasonal color moulting in mammals and birds: what makes them change in a warming world?” Biological examinations (2018). onlinelibrary.wiley.com/doi/full/10.1111/brv.12405 (opens in a new window) Winter is one of the four seasons of temperate zones. This is the season with the shortest days and the lowest temperatures. In areas further from the equator, winter is often marked by snow.
Blue spruce is a tree that really loves winter and is also very beautiful when covered in snow. He can live without sun, but still be beautiful and also be ready to “wear” decorations during the Christmas and New Year period. Astronomical winter – what most people call winter – is defined by the Earth`s position around the sun and extends from the winter solstice to the spring equinox. The winter solstice marks the time when the sun passes directly over the equator. “Winter 18/19” or the determination of the year in which the season begins or the year to which the greatest number of days belong, which for most definitions is the later year. In the Northern Hemisphere, the December solstice is the winter solstice. In the southern hemisphere, it is the summer solstice, the day with the longest hours of daylight. If it`s winter in the northern hemisphere, it`s summer in the southern hemisphere and vice versa. In many areas, winter brings snow and freezing temperatures.
The time of the winter solstice is when the height of the sun is most negative relative to the north or south pole; That is, the sun is farthest below the horizon, measured from the pole. The day this occurs has the shortest day and the longest night, with the length of the day increasing and the length of the night decreasing as the season progresses after the solstice. Wintergreen boxwood is a plant that really loves winter weather and, as you can understand from its name, is green even in winter. In addition, this little plant is really beautiful with a snow cover and reminds us that not everything sleeps in winter and you can always find real beauty in nature. In Greek mythology, Hades kidnapped Persephone to be his wife. Zeus ordered Hades to bring her back to Demeter, the goddess of the earth, and her mother. Hades persuaded Persephone to eat the food of the dead, so Zeus decreed that she should spend six months with Demeter and six months with Hades. While his daughter is with Hades, Demeter became depressed and caused winter.
