Africa and Central and South America are at about the same latitude, so why is the climate much hars

There are three main reasons:

1. Influence of land and sea location. The African continent is vast at the same latitude, and it is difficult for the warm and humid air currents of the ocean to enter the interior of Africa.

For Central and South America, which is narrow in size and susceptible to warm and humid air currents from the oceans.

2. The influence of terrain. At the same latitude, most of Africa is plateau, and most of Central and South America is plains and mountains. The warm and humid airflow of the Atlantic Ocean and the Indian Ocean is obviously blocked by the African plateau, and most of them have a savannah climate. The Amazon Plain of South America faces the Atlantic Ocean, and the warm and humid air currents of the Atlantic Ocean can drive straight into it, forming the largest tropical rainforest area in the world.

3. The influence of ocean currents. In terms of warm currents, the warm currents of Central and South America (Brazil Warm Current, South Equatorial Warm Current, North Equatorial Warm Current, and Gulf Warm Current) far exceed the warm currents along the coast of Africa in terms of number and influence. In terms of ocean currents, the Canary Cold Current and the Benguela Cold Current have a great impact on the coastal areas of Africa, which are the vast Sahara Desert and the Namib Desert and reach the Atlantic coast. The cold snaps in Central and South America, the Peruvian Snap, and the California Snap (blocked by the large Cordillera mountain system) only affect a small area of the country.

This problem is very complicated, first of all, you look at the topography map, the longitude comparison across Africa is larger than that of South America, so it is difficult for water vapor to convey the inland of the belt, South America is relatively narrow and long, and there are high mountains in the western part of South America, so that the water vapor transportation process plays a blocking role. Secondly, you look at the comparison of contour lines, the comparison of altitude, this truth is like the Qinghai-Tibet Plateau and Calcutta, India, why the latitude is about the same, but the climate and precipitation are much worse,,, second, you have to consider the influence of ocean currents, the passage of warm currents and cold currents have a greater impact on the climate, and you have to consider the impact of human beings on the environment, and then the impact of the environment on the local microclimate!

If you are a student, the factors considered for this kind of topic are actually similar: topography, ocean currents, high pressure and low pressure, human influence, influence of monsoon, etc.

It is mainly affected by the topography of the monsoon currents. Central and South America is surrounded by high mountains on the Pacific side, which prevents the Pacific monsoon from blowing inland. When the Atlantic monsoon blows to Central and South America, it blows from northeast to southwest.

When entering the Caribbean Sea, it is often affected by the nearby terrain and changes direction to North America. Africa, on the other hand, is relatively flat, with both the Atlantic and Indian Ocean monsoons blowing inland. The exception is North Africa, of course.

The two continents are too broad to be easily compared.

It is affected by various factors such as ocean currents, air pressure, and topography.

The climate difference between Africa and South America is still relatively large, in Africa, it belongs to the equator, so it is very hot, and in South America, it is closer to the North Pole, so the climate is relatively cool.

Similarities: both have a predominantly tropical climate.

Differences: 1. South America has a temperate climate, while Africa does not; 2. The climate of Africa presents a symmetrical distribution from north to south with the equator as the axis of symmetry, and the climate types of South America are complex and diverse.

Africa and South America both have tropical climates, but Africa is symmetrically distributed from north to south with the equator as the axis of symmetry, and the Amazon Plain in South America has a tropical rainforest climate with a hot and humid climate.

The same is that they are mainly tropical climates, and there are many differences, the most prominent of which is the humid and hot climate in South America and the arid climate in Africa. There are two reasons for this: first, the latitudinal position (relative to the equator) is different, the equator passes through central Africa, resulting in a symmetrical distribution of climate zones, and the two ends are under the control of high pressure, so there is a large area of extreme arid areas, and the scope of the tropical rainforest climate zone is limited by the East African plateau, and the area is relatively narrow; In South America, most of the north is located in the equatorial zone, and the high mountains in the west limit the influence range of high pressure, so it is generally dominated by tropical rainforest climate, and the desert steppe climate is not large.

The main reason is that the equator traverses central Africa, the Tropic of Cancer passes through the north and south of the continent, and most areas have direct sunlight twice a year, and the northern region through which the Tropic of Cancer passes is particularly wide, expanding the area controlled by the regression high pressure belt; The ground is dominated by plateaus, and the surface is not undulating, which is convenient for airflow operation; The northeast trade winds come from the interior of Asia, so the climate of Africa is dominated by hot and dry climate, and the climate type is obviously zonal, with the equator as the center and the symmetrical distribution from north to south is prominent. The equator of South America passes through the northern part of the continent, the widest part of the continent, so although most of it is tropical, it has a wide area of rainy areas; The Tropic of Capricorn passes through the southern part of the continent, but the land area is small, so the climate of South America is mainly warm and humid. The climate type has some symmetry only near the northern equator; The Andes, which is the main barrier to the climate, is close to the western Pacific coast, so the Pacific coast is a very narrow strip, and the climate type is arranged in a north-south direction.
