North-Siberian lowland (on the map it can be seendistinctly) represents a huge flat territory located in the northern part of Eastern Siberia. It occupies the northern lands of two regions of the Siberian Federal District: the Krasnoyarsk Territory and the Republic of Yakutia.
The lowland stretches for 600 km from the Taymyrthe Byrranga mountains in the north to the Putorana plateau in the south, and almost 1,500 km from the mouth of the Yenisei in the west to the Olenek River in the east. Thus, the lowland is located between 70 and 75 parallels of northern latitude, and between 83 and 125 degrees east longitude. That is, it covers the Taimyr peninsula from the south, extending from Kara to the Laptev Sea.
Where is the North-Siberian lowland and how does its location affect the climate? This question is quite interesting. Let's take a closer look at it.
Almost all of it is in the Arcticclimatic zone, and only a small area in the south-west is located in the subarctic zone. The predominantly North Siberian lowland is a tundra zone. However, in the south and south-west there are areas of forest-tundra, represented by deciduous thickets, and in the central zone of the Taimyr Peninsula, just as in the northeast, the territory passes through the arctic desert.
Primarily these are low-lying crested tundra withrare hilly or rocky hills up to 200 m, and sometimes up to 250 m. The area is densely packed with numerous rivers and lakes. The largest of them - the river. Anabar, Olenek, Pyasina, Khatanga, and the lakes - Taimyr, Kokora and Labaz. The tundra is strongly swamped.
The climate is arctic continental, summer is short, winter is very long. Frosts reach 50aboutC is below zero, and summer temperatures are no higher than 20aboutFROM.
As the North-Siberian lowland is locatednorth of the Arctic Circle, the summer and winter seasons are accompanied by a polar day and night. Autumn and spring periods are short. Seasons change takes 2-3 weeks. The amount of precipitation in the North-Siberian lowland is small: from 200 to 400 millimeters. Throughout the ground, the ground thaws only in the upper layer. This phenomenon is called "permafrost".
The North-Siberian lowland has enoughlean plant world. It is represented by mosses, lichens (berries), berry bushes (crawberry, blueberry, blueberry), dwarf birches and willows. In the southern part you can find deciduous woodlands, and in the decays protected from the wind, the dog rose and the low-mountain ash. Vegetation period is short: 6-8 weeks, but numerous angiosperms, polar poppies and sedges, manage to fade and give seeds to germination.
North-Siberian lowland is not too happydiversity of fauna. These are wild reindeer, arctic foxes, wolves, lemmings, polar owls and partridges. On Taimyr, the mammoths who were imported in the 1960s from Canada came to live, the musk oxen. In the summer, a huge number of waterfowl migrating birds are nesting in the tundra: geese, ducks, and geese.
The indigenous indigenous population is represented by the Nganasans, Enets, Dolgans and in the south - Evenks. The main occupation of representatives of these peoples is reindeer herding, hunting for fur animals and fishing.
