Winter
Winter is the coldest season of the year in polar and temperate zones (winter does not occur in the tropical zone). It occurs after autumn and before spring in each year. 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. 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).
Season
A season is a division of the year marked by changes in weather, ecology, and amount of daylight. Seasons result from Earth's orbit around the Sun and Earth's axial tilt relative to the ecliptic plane. In temperate and polar regions, the seasons are marked by changes in the intensity of sunlight that reaches the Earth's surface, variations of which may cause animals to undergo hibernation or to migrate, and plants to be dormant. During May, June, and July, the Northern Hemisphere is exposed to more direct sunlight because the hemisphere faces the Sun. The same is true of the Southern Hemisphere in November, December, and January.
Climate of Brazil
The climate of Brazil varies considerably mostly from tropical north (the equator traverses the mouth of the Amazon) to temperate zones south of the Tropic of Capricorn (23°26' S latitude). Temperatures below the equator are high, averaging above , but not reaching the summer extremes of up to in the temperate zones. There is little seasonal variation near the equator, although at times it can get cool enough to need to wear a jacket, especially in the rain. Average temperatures below the Tropic of Capricorn are mild, ranging from to . At the country's other extreme, there are frosts south of the Tropic of Capricorn and during the winter (June–September).
Climate of the United Kingdom
The United Kingdom straddles the higher mid-latitudes between 49° and 61° N. It is on the western seaboard of Afro-Eurasia, the world's largest land mass. Since the UK is always in or close to the path of the polar front jet stream, frequent changes in pressure and unsettled weather are typical. Many types of weather can be experienced in a single day. In general the climate of the UK is cool and often cloudy, and hot temperatures are infrequent. The climate in the United Kingdom is defined as a temperate oceanic climate, or "Cfb" on the Köppen climate classification system, a classification it shares with most of north-west Europe.
List of ecoregions in North America (CEC)
This list of ecoregions of North America provides an overview of North American ecoregions designated by the Commission for Environmental Cooperation (CEC) in its North American Environmental Atlas. It should not be confused with Wikipedia articles based on the classification system developed by the World Wildlife Fund, such as List of ecoregions (WWF) and Lists of ecoregions by country. The commission was established in 1994 by the member states of Canada, Mexico, and the United States to address regional environmental concerns under the North American Agreement on Environmental Cooperation (NAAEC), the environmental side accord to the North American Free Trade Agreement (NAFTA).
Geography of Norway
Norway is a country located in Northern Europe on the western and northern part of the Scandinavian Peninsula, bordering the North Sea to the southwest and the Skagerrak inlet to the south, the North Atlantic Ocean (Norwegian Sea) in the west and the Barents Sea to the northeast. Norway has a long land border with Sweden to the east, a shorter one with Finland in the northeast and a still shorter border with Russia in the far northeast. Norway has a very elongated shape, one of the longest and most rugged coastlines in the world, and some 50,000 islands off the extremely indented coastline. Mainland Norway ("fastlands-norge") covers 13° latitude, from 58°N to more than 71°N, (Svalbard north to 81°N), and covers the longitude from 5°E in Solund to 31°E in Vardø (Jan Mayen to 9°W, Kvitøya to 33°E).
Köppen climate classification
Köppen climate classification is one of the most widely used climate classification systems. It was first published by Russian German climatologist Wladimir Köppen in 1884, with several later modifications by Köppen, notably in 1918 and 1936. Later, German climatologist Rudolf Geiger (1954, 1961) collaborated with Köppen on changes to the classification system, which is thus sometimes called the Köppen–Geiger climate classification system. The Köppen climate classification system has been further modified, within the Trewartha climate classification system in the middle 1960s (revised in 1980).
