Different regions of the world receive different amounts of rainfall. There are regions that get flooded while some go without rain for years. Biomes are a community of plants and animals formed naturally in response to the physical environment around them. Yes, our topic today is rainfall in different biomes of the world. Have you ever wondered which biome receives 200 to 400 cm of rain and which ecosystem has the most rainfall? Well, don’t worry as this article will answer all your curiosities!

1. What are Biomes?

A biogeographical unit that a biological community inhabits in response to the physical environment around them is known as a biome. These biomes are formed as a result when different biological units share the same regional climate. It is a way to divide the surface of the Earth and these divisions are based on-

  • Animals and plants inhabiting the area
  • Climate patterns
  • Light and water received in that area
  • Soil types

2. What are Types of Biomes?

According to the type of environment the animals and plants are living in, the biomes can be broadly classified as follows:

  • Aquatic Biome: The habitats existing in every part of the world which is supporting life can be called aquatic biomes. Both freshwater and saltwater biomes are aquatic biomes. The freshwater biome, wetland biome, coral reef biome, and estuaries are the further divisions.
  • Desert Biome: The least amount of vegetation in the region is the distinguishable feature of these biomes. There are hot and cold desert biomes depending on their location. Hot deserts are extremely hot even in winters while cold deserts are freezing in summers too. 
  • Forest Biome: It is the largest biome with a wide variety of plants, animals, insects, and other living organisms. According to experts, about 30% of the landmass of the Earth is forest biome. They are further categorized on the basis of the trees and climates of the biome.
  • Grassland Biome: This biome is made up of hills of different types of grasses. The amount of vegetation in these biomes is mostly controlled through occasional wildfires. There are two types of grasslands, namely Savannah and temperate grassland.
  • Tundra Biome: This biome is the coldest on Earth and they are considered similar to a cold desert. The climatic conditions are harsh but different plants and animal species have evolved themselves to survive in these conditions. There are 2 types of tundras i.e. arctic and alpine.

3. Do Aquatic Biomes receive more Rainfall?

Before understanding which biome receives 200 to 400 cm of rain, let us first read whether aquatic biomes receive more rainfall or not. There is not a significant amount of rainfall that the aquatic biomes or the oceans of the world receive. It differs according to the specific regions, like desert aquatic biomes receiving less rainfall whereas it is the opposite for those in aquatic rainforests. However, the rainfall around the world pours over these water bodies gradually increasing their water levels. According to the researchers, the average annual rainfall adds more than 254 centimeters (2540 millimeters or 100 inches) of water into these aquatic biomes.

4. What Two Biomes receive the most Rainfall?

The amount of rainfall received by different biomes is determined by their location and the type of climate prevailing there. So, what two biomes receive the most rainfall? Take a look:

  • Forest Biomes – The amount of average annual rainfall in these biomes is 75 centimeters to 150 centimeters (30 to 60 inches).
  • Grassland Biomes – Average annual rainfall received in these biomes ranges between 50 centimeters and 90 centimeters (500 to 900 millimeters or 20 to 35 inches).

5. Which Biome receives 200 to 400 cm of Rain?

The location found in the equatorial and sub-equatorial biomes is said to receive a relatively high amount of rainfall. Equatorial biomes include tropical and temperate rainforests that are located near the equator. These areas receive an average of about 200 to 400 centimeters per year.

6. How much Rainfall is received by Desert Biomes?

Now that we are aware of which biome receives 200 to 400 cm of rain, let us also look at how much rainfall is received by desert biomes. Deserts remain dry and arid all year round. It is likely to receive the least amount of rainfall in a year which can be less than 50 cm of rain. 

7. How much Rain is received in the Tundra Biome?

Besides knowing which biome receives 200 to 400 cm of rain, note some facts related to the Tundra biome. The treeless regions in the Arctic and poles of the Earth are termed the Tundra Regions or Tundra Biomes. Here the climate is mostly cold and windy with very little to no rainfall. However, the average annual rainfall received in a year in Tundra Biomes can range from 15 centimeters to 25 centimeters (150 to 250 millimeters or 6 to 10 inches). (See How many biomes are there in Africa?)

8. Is Biome and Ecosystem the same?

Before understanding which ecosystem has the most rainfall, we need to know whether biomes and ecosystems are the same. Often both the terms are used interchangeably and both of them hold different meanings. The ecosystem is a defined area where living and non-living organisms interact with each other. Biomes regard only the living factors that are abiotic factors of the ecosystem; it is used for a wider area than the ecosystem. (See What is the Climate in Wetlands?)

9. Which Ecosystem has the Most Rainfall?

As you already read which biome receives 200 to 400 cm of rain, it is time to know which ecosystem has the most rainfall. Different ecosystems receive different amounts of rainfall which is never the same every year. Various factors affect the amount of rainfall in different ecosystems. However, the highest amount of average annual rainfall is received by tropical and temperate ecosystems, which means tropical and temperate rainforests.

10. Which Factors affect Rainfall in Different Biomes?

The amount of rainfall received by different biomes depends largely on the following factors:

  • Air Pattern: The global pattern of precipitation in these biomes is influenced by the movements of the air masses. For example, the areas near the latitudes 30° North and 30° South are a belt of global dry air. It means the amount of precipitation will be very less.
  • Temperature: The amount of precipitation is also affected by the temperature prevailing in that biome. Regions with more warm air tend to receive more rainfall because warm air holds more moisture. If the temperature is high, the amount of evaporation will also be high along with raised humidity leading to more precipitation. Lower temperatures mean low evaporation and considerably low precipitation. 
  • Location: The distance of biomes from the oceans and mountains also influences precipitation. If the biome is located near the oceans, the warm air will receive more evaporated water from the oceans, leading to more precipitation. Also, it is towards that side of the mountain where the moisture-laden winds cool and precipitate the area and will receive heavy rainfall. But if the area of the biome is in the rain shadow area, this will adversely affect the precipitation in that region and there will be less rainfall. Because by the time clouds and winds reach this side of the mountain there will be no moisture left in them.

The answer to the question of which biome receives 200 to 400 cm of rain is the equatorial and sub-equatorial regions. Share this article if you find it a good read. (Also read Why Plants in the Tundra retain their Dead Leaves?)
