Question

Почему в Северном полушарии сформировался тропический пустынный климат, а в южном тропический влажный?

Answer 1

Ответ:

Различный рельеф, горы не пропускают влажные воздушные массы вглубь материков, в результате более сухой климат, перепады температур больше.

Кроме этого у территорий на одной параллели разная удаленность от океанов и морей, чем ближе территория к водной поверхности, тем больше осадков выпадает, когда протекает теплое течение. Холодное течение вдоль берегов приводит к формированию более сухого климата.

Formation of Tropical Desert Climate in the Northern Hemisphere

The formation of a tropical desert climate in the Northern Hemisphere can be attributed to several factors. One key factor is the presence of high-pressure systems known as subtropical highs or subtropical anticyclones. These high-pressure systems are typically located around 30 degrees latitude in both hemispheres. In the Northern Hemisphere, the subtropical high-pressure system is known as the Bermuda-Azores High or the North Pacific High.

The presence of these high-pressure systems leads to the formation of tropical desert climates in the Northern Hemisphere for the following reasons:

1. Subsidence: The high-pressure systems in the Northern Hemisphere cause air to sink and compress as it moves towards the surface. This process, known as subsidence, inhibits the formation of clouds and precipitation. As a result, the air becomes dry, leading to arid conditions and the formation of deserts.

2. Trade Winds: The trade winds, which blow from east to west in the tropics, transport dry air from the subtropical high-pressure systems towards the equator. This dry air contributes to the aridity of the tropical desert regions in the Northern Hemisphere.

3. Rain Shadow Effect: Mountain ranges can also play a role in the formation of tropical desert climates. When moist air from the ocean encounters a mountain range, it is forced to rise. As the air rises, it cools and condenses, leading to the formation of clouds and precipitation on the windward side of the mountain. However, as the air descends on the leeward side of the mountain, it warms and dries out. This creates a rain shadow effect, where the leeward side of the mountain experiences arid conditions and the formation of deserts.

Formation of Tropical Humid Climate in the Southern Hemisphere

In contrast to the Northern Hemisphere, the Southern Hemisphere experiences a tropical humid climate in the tropics. This is primarily due to the following factors:

1. Intertropical Convergence Zone (ITCZ): The ITCZ is a low-pressure belt that encircles the Earth near the equator. It is characterized by the convergence of trade winds from both hemispheres. As the trade winds converge, they rise and cool, leading to the formation of clouds and precipitation. This results in a humid climate in the tropical regions of the Southern Hemisphere.

2. Ocean Currents: Ocean currents play a significant role in the distribution of heat and moisture around the globe. In the Southern Hemisphere, warm ocean currents, such as the Brazil Current and the East Australian Current, transport warm and moist air towards the tropics. This contributes to the humid conditions in the tropical regions of the Southern Hemisphere.

3. Lack of Large Landmasses: Unlike the Northern Hemisphere, the Southern Hemisphere has fewer large landmasses in the tropics. Landmasses tend to heat up more quickly than oceans, leading to the formation of high-pressure systems and arid conditions. The absence of large landmasses in the Southern Hemisphere allows for the maintenance of a more humid climate in the tropics.

In conclusion, the formation of a tropical desert climate in the Northern Hemisphere can be attributed to factors such as the presence of subtropical high-pressure systems, trade winds, and the rain shadow effect. On the other hand, the formation of a tropical humid climate in the Southern Hemisphere is influenced by the ITCZ, ocean currents, and the absence of large landmasses in the tropics.
