Steppe Climate - Geography Notes

Steppes are flat grassland landscapes found in moderate climates. Steppe Climate falls in between the tropical and polar regions. Steppes have a warm/hot climate in the summer and a frigid environment in the winter. Steppe Climate is a type of climate and part of the UPSC Geography Syllabus.

Steppes

Steppe Climate - Concept

• A steppe is a grassy, dry plain. Steppes grow in temperate climates(Temperate climates experience distinct seasonal temperature changes, with cold winters and warm summers) between the tropics and the poles.
• Steppes are found in moderate climates between the tropics and the poles.
• Seasonal temperature fluctuations are noticeable in temperate regions, with chilly winters and pleasant summers.
• Steppes are semi-arid, receiving 25 to 50 centimeters (10-20 inches) of rain per year.

Distribution

• They are found deep within the continents.
• Located in the Westerly Wind Belt [middle latitudes or temperate zone].
• Due to confidentiality [deep within the interiors of continents where rain-bearing winds do not reach], grasslands are nearly treeless.
• They are known as the Steppes in Eurasia, and they reach eastward from the Black Sea's coasts to the foothills of the Altai Mountains. [2,000 miles long belt].

Distribution of Steppe climates

Climate

Temperature

• The climate is continental, with temperature extremes.
• Summer and winter temperatures are vastly different.
• Summers are scorching, while winters are bitterly cold.
• Summers are hot, with temperatures ranging from 18 to 20 degrees Celsius.
• In the southern hemisphere, the steppe climate is never harsh.

Precipitation

• The average rainfall is roughly 45 cm, although it varies from 25 cm to 75 cm depending on where you are.
• The wettest months are June and July (late spring and early summer).
• The majority of the winter months see about 2.5 cm of precipitation, which is carried in by Westerly depressions and falls in the form of snow.
• In the southern hemisphere, the marine influence creates higher rainfall.

Natural Vegetation

• Grassland is dominated by grasses, with annual and perennial dwarf varieties intermixed in varying numbers depending on the location.
• As the average height of the grass is connected with rainfall, tall-, medium-, and short-grass prairie zones can be found throughout a longitudinal gradient across North America from east to west.
• Between spring, when the grasses are green and the dwarfs are in the flowering stage, and summertime, when brown, seeded, and dying plants prevail, the landscape changes dramatically.
• Some steppes, particularly in dry locations, are dominated by shrubs (shrub-steppes), and differ from deserts chiefly in their higher latitudes, lower mean temperatures, and reduced diversity.

Economic Development of Steppes

Wheat and Maize Cultivation

• Cultivation was unknown just before the turn of the century, and the region was one of the world's most sparsely populated areas.
• The grasslands have been plowed up for vast, mechanical wheat production in recent years, and they are now known as the "granaries of the world" [Prairies].
• Maize, in addition to wheat, is becoming more popular in warmer and wetter regions.

Ranching

• For cattle and sheep, tufted grasses have been replaced by more nutritious Lucerne or alfalfa grass.
• These temperate grasslands are presently the world's most important ranching locations.

Nomadic herding

• This sort of grazing by migrating animals has practically vanished from the big grasslands. Herders included nomadic groups such as the Kirghiz and Kazakhs.
• The nomads' difficult environment, which included extended droughts and inconsistent rains, developed the Kirghiz, a brave and fearless tribe who resisted Russian enslavement for a long time.
• They are now being pushed to settle down under the Communist dictatorship.
• For grazing and cereal production, the steppes have been transformed into massive community farms and state farms.

Extensive mechanized wheat cultivation

• Ploughing and harvesting are relatively straightforward in the Steppes and other temperate grasslands around the world due to their levelness.
• On the Prairies, Argentina's Pampas, Ukraine's Steppes, and Australia's Downs, agriculture is completely mechanized.

Pastoral farming

• Animal ranching thrives in the natural environment.
• The temperate grasslands became key pastoral zones after the invention of refrigerated ships in the late nineteenth century, shipping large quantities of beef, mutton, wool, and hides.
• In some regions of the North American grasslands, milk, butter, cheese, and other dairy products are also essential.

Significance

• Steppe Climate is one of the most important travel and commercial routes in the world.
• They are the best grounds for wheat cultivation.

Conclusion

Steppe Climate is one of the significant climates not only as a separate entity but also as a whole as it affects climatological parameters. Besides, their environmental contribution is huge.
