Interior Alaska is the central region of Alaska's territory, roughly bounded by the Alaska Range to the south and the Brooks Range to the north. It is largely wilderness. Mountains include Denali in the Alaska Range, the Wrangell Mountains, and the Ray Mountains. The native people of the interior are Alaskan Athabaskans. The largest city in the interior is Fairbanks, Alaska's second-largest city, in the Tanana Valley. Other towns include North Pole, just southeast of Fairbanks, Eagle, Tok, Glennallen, Delta Junction, Nenana, Anderson, Healy and Cantwell. The interior region has an estimated population of 113,154.

The polar climate regions are characterized by a lack of warm summers but with varying winters. Every month a polar climate has an average temperature of less than 10 °C (50 °F). Regions with a polar climate cover more than 20% of the Earth's area. Most of these regions are far from the equator and near the poles, and in this case, winter days are extremely short and summer days are extremely long. A polar climate consists of cool summers and very cold winters, which results in treeless tundras, glaciers, or a permanent or semi-permanent layer of ice. It is identified with the letter E in the Köppen climate classification.

Verkhoyansk is a town in Verkhoyansky District of the Sakha Republic, Russia, located on the Yana River in the Arctic Circle, 92 kilometers (57 mi) from Batagay, the administrative center of the district, and 675 kilometers (419 mi) north of Yakutsk, the capital of the Sakha republic. As of the 2010 Census, its population was 1,311. Verkhoyansk holds the record for the hottest temperature ever recorded north of the Arctic Circle, with 38.0 °C (100.4 °F), and it also holds the record for the coldest temperature ever recorded in Asia, −67.8 °C (−90.0 °F). The cold record is shared with Oymyakon.

Continental climates often have a significant annual variation in temperature. They tend to occur in central and eastern parts of the three northern-tier continents, typically in the middle latitudes, often within large landmasses, where prevailing winds blow overland bringing some precipitation, and temperatures are not moderated by oceans. Continental climates occur mostly in the Northern Hemisphere due to the large landmasses found there. Most of northeastern China, eastern and southeastern Europe, much of Russia south of the Arctic Circle, central and southeastern Canada, and the central and northeastern United States have this type of climate. Continentality is a measure of the degree to which a region experiences this type of climate.

A Mediterranean climate, also called a dry summer climate, described by Köppen and Trewartha as Cs, is a temperate climate type that occurs in the lower mid-latitudes. Such climates typically have dry summers and wet winters, with summer conditions being hot and winter conditions typically being mild. These weather conditions are typically experienced in the majority of Mediterranean-climate regions and countries, but remain highly dependent on proximity to the ocean, altitude and geographical location.

The Köppen climate classification divides Earth climates into five main climate groups, with each group being divided based on patterns of seasonal precipitation and temperature. The five main groups are A (tropical), B (arid), C (temperate), D (continental), and E (polar). Each group and subgroup is represented by a letter. All climates are assigned a main group. All climates except for those in the E group are assigned a seasonal precipitation subgroup. For example, Af indicates a tropical rainforest climate. The system assigns a temperature subgroup for all groups other than those in the A group, indicated by the third letter for climates in B, C, D, and the second letter for climates in E. For example, Cfb indicates an oceanic climate with warm summers as indicated by the ending b. Climates are classified based on specific criteria unique to each climate type.

An oceanic climate, also known as a marine climate or maritime climate, is the temperate climate sub-type in Köppen classification represented as Cfb, typical of west coasts in higher middle latitudes of continents, generally featuring cool to warm summers and cool to mild winters, with a relatively narrow annual temperature range and few extremes of temperature. Oceanic climates can be found in both hemispheres generally between 40 and 60 degrees latitude, with subpolar versions extending to 70 degrees latitude in some coastal areas. Other varieties of climates usually classified together with these include subtropical highland climates, represented as Cwb or Cfb, and subpolar oceanic or cold subtropical highland climates, represented as Cfc or Cwc. Subtropical highland climates occur in some mountainous parts of the subtropics or tropics, some of which have monsoon influence, while their cold variants and subpolar oceanic climates occur near polar or tundra regions.

A humid continental climate is a climatic region defined by Russo-German climatologist Wladimir Köppen in 1900, typified by four distinct seasons and large seasonal temperature differences, with warm to hot summers, and cold and snowy winters. Precipitation is usually distributed throughout the year, but often these regions do have dry seasons. The definition of this climate in terms of temperature is as follows: the mean temperature of the coldest month must be below 0 °C (32.0 °F) or −3 °C (26.6 °F) depending on the isotherm, and there must be at least four months whose mean temperatures are at or above 10 °C (50 °F). In addition, the location in question must not be semi-arid or arid. The cooler Dfb, Dwb, and Dsb subtypes are also known as hemiboreal climates. Although amount of snowfall is not a factor used in defining the humid continental climate, snow during the winter in this type of climate is almost a guarantee, either intermittently throughout the winter months near the poleward or coastal margins, or persistently throughout the winter months elsewhere in the climate zone.
In climatology, the term microthermal is used to denote the continental climates of Eurasia and North America.

Seni District is a district within the Nagqu of the Tibet Autonomous Region, China.

Climate of Peru describes the diverse climates of this large South American country with an area of 1,285,216 km2 (496,225 sq mi). Peru is located entirely in the tropics but features desert and mountain climates as well as tropical rainforests. Elevations above sea level in the country range from −37 to 6,778 m and precipitation ranges from less than 20 mm (0.79 in) annually to more than 8,000 mm (310 in). There are three main climatic regions: the Pacific Ocean coast is one of the driest deserts in the world but with some unique features; the high Andes mountains have a variety of microclimates depending on elevation and exposure and with temperatures and precipitation from temperate to polar and wet to dry; and the Amazon basin has tropical climates, mostly with abundant precipitation, along with sub-tropical climates in elevations above 1,550 m (5,090 ft).
Galuut is a sum (district) of Bayankhongor Province in southern Mongolia. In 2006, its population was 4,012.

Alaska occupies the northwestern portion of the North American continent and is bordered only by Canada on the east. It is one of two U.S. states not bordered by another state; Hawaii is the other. Alaska has more ocean coastline than all of the other U.S. states combined. About 500 miles (800 km) of Canadian territory consisting of British Columbia separate Alaska from Washington U.S. state. Alaska is thus an exclave of the United States that is part of the continental U.S. and the U.S. West Coast, but is not part of the contiguous U.S.

The climate of Alaska is determined by average temperatures and precipitation received statewide over many years. The extratropical storm track runs along the Aleutian Island chain, across the Alaska Peninsula, and along the coastal area of the Gulf of Alaska which exposes these parts of the state to a large majority of the storms crossing the North Pacific. The climate in Juneau and the southeast panhandle is a mid-latitude oceanic climate, in the southern sections and a subarctic oceanic climate in the northern parts. The climate in Southcentral Alaska is a subarctic climate due to its short, cool summers. The climate of the interior of Alaska is best described as extreme and is the best example of a true subarctic climate, as the highest and lowest recorded temperatures in Alaska have both occurred in the interior. The climate in the extreme north of Alaska is an Arctic climate with long, cold winters, and cool summers where snow is possible year-round.

The climate of the United States varies due to changes in latitude, and a range of geographic features, including mountains and deserts. Generally, on the mainland, the climate of the U.S. becomes warmer the farther south one travels, and drier the farther west, until one reaches the West Coast.

The climate of Chile comprises a wide range of weather conditions across a large geographic scale, extending across 38 degrees in latitude, making generalizations difficult. According to the Köppen system, Chile within its borders hosts at least seven major climatic subtypes, ranging from low desert in the north, to alpine tundra and glaciers in the east and southeast, tropical rainforest in Easter Island, Oceanic in the south and Mediterranean climate in central Chile. There are four seasons in most of the country: summer, autumn, winter, and spring.

The climate of Russia is formed under the influence of several determining factors. The enormous size of the country and the remoteness of many areas from the sea result in the dominance of the continental climate, which is prevalent in European and Asian Russia except for the tundra and the extreme southwest. Mountains in the south obstructing the flow of warm air masses from the Indian Ocean and the plain of the west and north makes the country open to Arctic and Atlantic influences. Russia's climate, despite its enormous geographical extent, is generally warm to hot in the summer and cold to very cold in the winter, with snow cover typically present over the vast majority of the country's territory in the winter months, with the exception of the country's southernmost territories, the North Caucasus. Russia's far northeast, subject to an extreme subarctic climate, experiences the coldest winters of any permanently settled region in the world, with Yakutsk, the capital of the Sakha Republic, being the world's coldest major city and Oymyakon, also in the Sakha Republic, being the world's coldest permanently inhabited settlement.

The climate of Norway is more temperate than could be expected for such high latitudes. This is mainly due to the North Atlantic Current with its extension, the Norwegian Current, raising the air temperature; the prevailing southwesterlies bringing mild air onshore; and the general southwest–northeast orientation of the coast, which allows the westerlies to penetrate into the Arctic. The January average in Brønnøysund is 15.8C (28.6F) higher than the January average in Nome, Alaska, even though both towns are situated on the west coast of the continents at 65°N. In July the difference is reduced to 3.2C (5.8F). The January average of Yakutsk, in Siberia but slightly further south, is 42.3C (76.1F) lower than in Brønnøysund.

Estonia lies in the northern part of the temperate climate zone and in the transition zone between maritime and continental climate. Because Estonia is continuously warmed by maritime air influenced by the heat content of the northern Atlantic Ocean, it has a milder climate despite its northern latitude. The Baltic Sea causes differences between the climate of coastal and inland areas.

The Selenge–Orkhon forest steppe ecoregion stretches across north central Mongolia, and follows the Selenga River northeast into Russia. The ecoregion is itself at high elevations, but surrounded by higher mountain ranges. As a transition zone between taiga and steppe, it features conifer forests on the north slopes of mountains, and pine/aspen stands on southern slopes. It has an area of 227,660 square kilometres (87,900 sq mi).
