Winter - Wikipedia. Winter is the coldest season of the year in polar and temperate climates, between autumn and spring. Winter is caused by the axis of the Earth in that hemisphere being oriented away from the Sun. Different cultures define different dates as the start of winter, and some use a definition based on weather. December solstice 2016 arrives on. At the December solstice, the Northern Hemisphere is leaning most away from the sun for the year. The December Solstice is either on. Sunset on the Winter Solstice? December solstice and. Winter Walk on the Wharf has no. Partridge in a Bear Tree will be doing their Grand Opening/Holiday Open House this Sat and Sun during. Zach Mack Published On 12/02/2015. There are times in winter when the sun. Sign up here for our daily Thrillist. Winter Has No Sun is ultimately a film about change. Winter Has No Sun (2015). When it is winter in the Northern Hemisphere, it is summer in the Southern Hemisphere, and vice versa. In many regions, winter is associated with snow and freezing temperatures. The moment of winter solstice is when the sun's elevation with respect to the North or South Pole is at its most negative value (that is, the sun is at its farthest below the horizon as measured from the pole), meaning this day will have the shortest day and the longest night. The earliest sunset and latest sunrise dates outside the polar regions differ from the date of the winter solstice, however, and these depend on latitude, due to the variation in the solar day throughout the year caused by the Earth's elliptical orbit (see earliest and latest sunrise and sunset). Etymology. The Earth is tilted at an angle of 2. This variation brings about seasons. When it is winter in the Northern Hemisphere, the Southern Hemisphere faces the Sun more directly and thus experiences warmer temperatures than the Northern Hemisphere. Conversely, winter in the Southern Hemisphere occurs when the Northern Hemisphere is tilted more toward the Sun. From the perspective of an observer on the Earth, the winter Sun has a lower maximum altitude in the sky than the summer Sun. During winter in either hemisphere, the lower altitude of the Sun causes the sunlight to hit that hemisphere at an oblique angle. In regions experiencing winter, the same amount of solar radiation is spread out over a larger area. This effect is compounded by the larger distance that the light must travel through the atmosphere, allowing the atmosphere to dissipate more heat. Compared with these effects, the changes in the distance of the earth from the sun are negligible. The manifestation of the meteorological winter (freezing temperatures) in the northerly snow. A case in point is Canada, a country normally associated with tough winters. Winnipeg on the Great Plains at a relative distance from large bodies of water has a January high of . A similar effect, although with less extreme differentials, is found in Europe where in spite of the northerly latitude of the islands, the British Isles has not a single non- mountain weather station with a below- freezing mean temperature. This corresponds to the months of December, January and February in the Northern Hemisphere, and June, July and August in the Southern Hemisphere. The coldest average temperatures of the season are typically experienced in January or February in the Northern Hemisphere and in June, July or August in the Southern Hemisphere. Nighttime predominates in the winter season, and in some regions winter has the highest rate of precipitation as well as prolonged dampness because of permanent snow cover or high precipitation rates coupled with low temperatures, precluding evaporation. Blizzards often develop and cause many transportation delays. Diamond dust, also known as ice needles or ice crystals, forms at temperatures approaching . As a result, the coldest January on record in 1. Stockholm. In the Southern Hemisphere, the more maritime climate and the relative lack of land south of 4. In this region, snow occurs every year in elevated regions such as the Andes, the Great Dividing Range in Australia, and the mountains of New Zealand, and also occurs in the southerly Patagonia region of South America. Snow occurs year- round in Antarctica. Astronomical and other calendar- based reckoning. In one version of this definition, winter begins at the winter solstice and ends at the vernal equinox. In some cultures, the season is regarded as beginning at the solstice and ending on the following equinox. In the UK, meteorologists consider winter to be the three coldest months of December, January and February. In Celtic nations such as Ireland (using the Irish calendar) and in Scandinavia, the winter solstice is traditionally considered as midwinter, with the winter season beginning 1 November, on All Hallows, or Samhain. Winter ends and spring begins on Imbolc, or Candlemas, which is 1 or 2 February. This system of seasons is based on the length of days exclusively. Martin's Day (1. 1 November), as the first calendar day of winter. Also, Valentine's Day (1. February) is recognized by some countries as heralding the first rites of spring, such as flowers blooming. In Chinese astronomy and other East Asian calendars, winter is taken to commence on or around 7 November, with the Ji. Depending on seasonal lag, this period will vary between climatic regions. Cultural influences such as Christmas creep may have led to the winter season being perceived as beginning earlier in recent years, although high latitude countries like Canada are usually well into their real winters before the December solstice. Ecological reckoning and activity. It is one of six seasons recognized by most ecologists who customarily use the term hibernal for this period of the year (the other ecological seasons being prevernal, vernal, estival, serotinal, and autumnal). The appearance of flowering plants like the crocus can mark the change from ecological winter to the prevernal season as early as late January in mild temperate climates. To survive the harshness of winter, many animals have developed different behavioral and morphological adaptations for overwintering: Migration is a common effect of winter upon animals, notably birds. However, the majority of birds do not migrate. Some butterflies also migrate seasonally. Hibernation is a state of reduced metabolic activity during the winter. This is the case for squirrels, beavers, skunks, badgers, and raccoons. Resistance is observed when an animal endures winter but changes in ways such as color and musculature. The color of the fur or plumage changes to white (in order to be confused with snow) and thus retains its cryptic coloration year- round. Examples are the rock ptarmigan, Arctic fox, weasel, white- tailed jackrabbit, and mountain hare. Some fur- coated mammals grow a heavier coat during the winter; this improves the heat- retention qualities of the fur. The coat is then shed following the winter season to allow better cooling. The heavier coat in winter made it a favorite season for trappers, who sought more profitable skins. Snow also affects the ways animals behave; many take advantage of the insulating properties of snow by burrowing in it. Mice and voles typically live under the snow layer. Some annual plants never survive the winter. Other annual plants require winter cold to complete their life cycle, this is known as vernalization. As for perennials, many small ones profit from the insulating effects of snow by being buried in it.
