23-432: The uplands lie in the cool continental climate zone, characterised by large fluctuations in seasonal temperatures and generally little rainfall. Outside of the cities in the region, population density is generally between 28 and 129 inhabitants per square mile. The uplands run for approximately 800 kilometres (500 mi) in a southwest-northeasterly direction from Volgograd to Kazan . The Tsimlyansk Reservoir lies at

46-632: A counterclockwise pattern. Hurricanes and tropical storms (massive low-pressure systems) spin counterclockwise in the Northern Hemisphere. The shadow of a sundial moves clockwise on latitudes north of the subsolar point and anticlockwise to the south. During the day at these latitudes, the Sun tends to rise to its maximum at a southerly position. Between the Tropic of Cancer and the Equator,

69-460: A significant annual variation in temperature (warm to hot summers and cold winters). They tend to occur in central and eastern parts of the three northern-tier continents ( North America , Europe , and Asia ), typically in the middle latitudes (40 to 55 or 60 degrees north), often within large landmasses, where prevailing winds blow overland bringing some precipitation, and temperatures are not moderated by oceans. Continental climates occur mostly in

92-697: Is somewhat more stable than winter weather. Continental climates are considered as temperate climate varieties due to their location in the temperate zones, but are classified separately from other temperate climates in the Köppen climate classification system where they are identified by their first letter, a capital D . In the Trewartha climate classification , they are identified as Dc . Continental climate has at least one month averaging below 0 °C (32 °F) and at least one month averaging above 10 °C (50 °F). Annual precipitation in this zone

115-669: Is usually between 600 millimetres (24 in) and 1,200 millimetres (47 in), The timing of intermediate spring-like or autumn-like temperatures in this zone vary depending on latitude and/or elevation. For example, spring may arrive as soon as March (in Northern hemisphere , September in Southern hemisphere ) in the southern (in Northern hemisphere, northern in Southern hemisphere), parts of this zone or as late as May (November) in

138-607: The Equator . For other planets in the Solar System , north is defined as being in the same celestial hemisphere relative to the invariable plane of the Solar System as Earth's North Pole . Due to Earth's axial tilt of 23.439281°, there is a seasonal variation in the lengths of the day and night. There is also a seasonal variation in temperatures, which lags the variation in day and night. Conventionally, winter in

161-410: The Northern temperate zone . The changes in these regions between summer and winter are generally mild, rather than extreme hot or cold. However, a temperate climate can have very unpredictable weather. Tropical regions (between the Tropic of Cancer and the Equator, 0° latitude) are generally hot all year round and tend to experience a rainy season during the summer months, and a dry season during

184-583: The last glacial period ended about 10,000 years ago. Earth is currently in an interglacial period of the Quaternary , called the Holocene . The glaciations that occurred during the glacial period covered many areas of the Northern Hemisphere. The Arctic is a region around the North Pole (90° latitude ). Its climate is characterized by cold winters and cool summers. Precipitation mostly comes in

207-492: The westerlies , push the currents back to the east, producing a closed clockwise loop. Its surface is 60.7% water, compared with 80.9% water in the case of the Southern Hemisphere , and it contains 67.3% of Earth's land. The continents of North America and mainland Eurasia are located entirely in the Northern Hemisphere, together with about two-thirds of Africa and a small part of South America . During

230-516: The 2.5 million years of the Pleistocene , numerous cold phases called glacials ( Quaternary ice age ), or significant advances of continental ice sheets, in Europe and North America , occurred at intervals of approximately 40,000 to 100,000 years. The long glacial periods were separated by more temperate and shorter interglacials which lasted about 10,000–15,000 years. The last cold episode of

253-545: 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. In continental climates, precipitation tends to be moderate in amount, concentrated mostly in

276-661: The Northern Hemisphere is taken as the period from the December solstice (typically December 21 UTC ) to the March equinox (typically March 20 UTC), while summer is taken as the period from the June solstice through to the September equinox (typically on 23 September UTC). The dates vary each year due to the difference between the calendar year and the astronomical year . Within the Northern Hemisphere, oceanic currents can change

299-734: The Sun can be seen to the north, directly overhead, or to the south at noon, depending on the time of year. In the Southern Hemisphere, the midday Sun is predominantly in the north. When viewed from the Northern Hemisphere, the Moon appears inverted compared to a view from the Southern Hemisphere. The North Pole faces away from the Galactic Center of the Milky Way . This results in the Milky Way being sparser and dimmer in

322-611: The banks of the Volga there are several large cities, such as (from north to south) Kazan , Ulyanovsk , Saransk , Penza , Syzran , Saratov and Volgograd . The hill ranges along the Volga banks are traditionally called mountains ( горы ), despite being of low height. The main ones are: This article about a location in the Volga Federal District is a stub . You can help Misplaced Pages by expanding it . Continental climate Continental climates often have

345-590: The form of snow. Areas inside the Arctic Circle (66°34′ latitude) experience some days in summer when the Sun never sets, and some days during the winter when it never rises. The duration of these phases varies from one day for locations right on the Arctic Circle to several months near the Pole, which is the middle of the Northern Hemisphere. Between the Arctic Circle and the Tropic of Cancer (23°26′ latitude) lies

368-403: The influence of cool oceanic air masses is more marked toward the west. In western and eastern Asia, and the central United States these climates grade off toward humid subtropical climates ( Cfa/Cwa ), subtropical highland climates ( Cwb ), or Mediterranean climates ( Csa/Csb ) to the south. Northern hemisphere The Northern Hemisphere is the half of Earth that is north of

391-472: The north (south). Summers are warm or hot while winters are below freezing and sustain lots of frost. Continental climates exist where cold air masses infiltrate during the winter from shorter days and warm air masses form in summer under conditions of high sun and longer days. Places with continental climates are as a rule either far from any moderating effect of oceans or are so situated that prevailing winds tend to head offshore. Such regions get quite warm in

414-773: The southwestern end of the Volga Upland, with the Kuybyshev Reservoir at the northeastern end. The landscape on the Volga Uplands is hilly, and several rivers have cut into it, such as the Khopyor , Medveditsa and the Sura . The Volga–Don Canal cuts through the lowlands between the Volga Uplands to the north and the adjacent Yergeni Hills to the south. The Volga Uplands themselves are rather sparsely populated, but along their edges and in particular along

437-569: The summer, achieving temperatures characteristic of tropical climates but are colder than any other climates of similar latitude in the winter. In the Köppen climate system, these climates grade off toward temperate climates equator-ward where winters are less severe and semi-arid climates or arid climates where precipitation becomes inadequate for tall-grass prairies and shrublands. In Europe these climates may grade off into oceanic climates ( Cfb ) or subpolar oceanic climates ( Cfc ) in which

460-580: The warmer months. Only a few areas—in the mountains of the Pacific Northwest of North America and in Iran , northern Iraq , adjacent Turkey , Afghanistan , Pakistan , and Central Asia —show a winter maximum in precipitation. A portion of the annual precipitation falls as snowfall, and snow often remains on the ground for more than a month. Summers in continental climates can feature thunderstorms and frequent hot temperatures; however, summer weather

483-500: The weather patterns that affect many factors within the north coast. For the same reason, flows of air down toward the northern surface of the Earth tend to spread across the surface in a clockwise pattern. Thus, clockwise air circulation is characteristic of high pressure weather cells in the Northern Hemisphere. Conversely, air rising from the northern surface of the Earth (creating a region of low pressure) tends to draw air toward it in

506-462: The weather patterns that affect many factors within the north coast. Such events include El Niño–Southern Oscillation . Trade winds blow from east to west just above the equator. The winds pull surface water with them, creating currents, which flow westward due to the Coriolis effect . The currents then bend to the right, heading north. At about 30 degrees north latitude, a different set of winds,

529-489: The winter months. In the Northern Hemisphere, objects moving across or above the surface of the Earth tend to turn to the right because of the Coriolis effect . As a result, large-scale horizontal flows of air or water tend to form clockwise-turning gyres . These are best seen in ocean circulation patterns in the North Atlantic and North Pacific oceans. Within the Northern Hemisphere, oceanic currents can change
