Question

Какие особенности климата Южной Америки выделяют ее среди других материков?Почему в Южной Америки климат не такой жаркий как в Африке и Австралии???

Answer 1

1)Общая характеристика климата материка. Климат Южной, Америки имеет много общего с климатом Африки. Большая часть материка лежит в тех же климатических поясах, что и Африка. Как и Африка, Южная Америка получает в основном много солнечного тепла, что обусловливает преобладание высоких температур, особенно на севере материка. Только на юге температура воздуха зимой опускается ниже +3°С, а иногда падает ниже 0°С. На одних и тех же широтах климат материков сходный. Однако в их климате есть и существенные различия.Южная Америка - самый влажный материк Земли и не такой жаркий, как Африка. На нем нет обширных сухих территорий, как в Африке. Часть Южной Америки расположена в умеренном климатическом поясе. В отличие от Африки все климатические пояса, кроме субэкваториального, сменяют друг друга только при движении к югу от экватора. На материке хорошо выражена высотная климатическая поясность в горах. В целом климат Южной Америки разнообразнее климата Африки.

Climate Features of South America

South America is known for its diverse climate due to its vast size and geographical features. Here are some of the key features that distinguish the climate of South America from other continents:

1. Latitude and Geographical Extent: South America extends from about 12°N to 55°S latitude, covering a wide range of latitudes. This results in a variety of climates, from tropical in the north to subpolar in the south.

2. Andes Mountains: The Andes Mountains, which run along the western coast of South America, have a significant impact on the climate of the continent. They create a rain shadow effect, causing the western side of the mountains to be dry, while the eastern side receives more rainfall.

3. Amazon Rainforest: The Amazon Rainforest, located in the northern part of South America, is the largest tropical rainforest in the world. It influences the climate by releasing moisture into the atmosphere through evapotranspiration, which contributes to the formation of rain clouds and rainfall in the region.

4. Ocean Currents: The ocean currents surrounding South America also play a role in shaping its climate. The cold Peru Current flows northward along the western coast, bringing cool temperatures and arid conditions. In contrast, the warm Brazil Current flows southward along the eastern coast, moderating temperatures and contributing to higher rainfall.

5. Trade Winds: The trade winds, which blow from east to west across the equator, affect the climate of South America. The northeast trade winds bring moisture from the Atlantic Ocean to the northeastern part of the continent, resulting in a wetter climate. The southeast trade winds, on the other hand, bring drier conditions to the southeastern regions.

6. Elevation: South America has diverse elevations, ranging from low-lying coastal areas to high plateaus and mountains. Higher elevations generally have cooler temperatures, while lower elevations tend to be warmer.

7. Seasonal Variations: South America experiences distinct seasons, with variations in temperature and rainfall throughout the year. The timing and intensity of these seasons vary across different regions of the continent.

Why is the Climate in South America Not as Hot as in Africa and Australia?

While South America does have some hot regions, such as the Amazon Basin and parts of the northeastern coast, its overall climate is not as consistently hot as Africa and Australia. Several factors contribute to this difference:

1. Latitude: South America is located at higher latitudes compared to Africa and Australia. As a result, it receives less direct sunlight, leading to milder temperatures.

2. Ocean Currents: The ocean currents surrounding South America, such as the cold Peru Current and the warm Brazil Current, help moderate temperatures along the coast. In contrast, Africa and Australia are influenced by warm ocean currents, such as the Agulhas Current and the Leeuwin Current, which contribute to hotter climates.

3. Geographical Features: The presence of the Andes Mountains in South America creates a barrier that affects the movement of air masses and influences the distribution of rainfall. This can lead to cooler temperatures in some regions.

4. Vegetation: The Amazon Rainforest in South America plays a role in regulating temperatures by providing shade and releasing moisture into the atmosphere through evapotranspiration. This helps to cool the region and prevent extreme heat.

5. Air Circulation Patterns: The global atmospheric circulation patterns, such as the Hadley Cell, also influence the climate. South America is located in the mid-latitudes of the Hadley Cell, where air descends and warms, resulting in generally milder temperatures compared to the tropical latitudes of Africa and Australia.

It's important to note that climate is a complex system influenced by multiple factors, and there can be regional variations within continents. The information provided here gives a general overview of the climate features of South America and the reasons why its climate is not as hot as in Africa and Australia.
