In general, tropical rainforests have hot and humid climates where it rains virtually everyday. The level of rainfall depends on the time of year. Temperatures vary through the year – but much less than the rainfall. Over the year, the temperature only varies by 2°C.

As tropical rainforests are located on or close to the Equator, the climate is typically warm and wet. The high rainfall and year-round high temperatures are ideal conditions for vegetation growth. The atmosphere in the tropical rainforest is hot and humid as the result of high temperatures and abundance of water.

The average temperature in tropical rainforests ranges from 70 to 85°F (21 to 30°C). The environment is pretty wet in tropical rainforests, maintaining a high humidity of 77% to 88% year-round. The yearly rainfall ranges from 80 to 400 inches (200 to 1000 cm), and it can rain hard.

In tropical rainforests, the fog comes from the changes in temperature between night and day. In both cases, it important for retaining the moisture. During seasons of no rain, the fog of the temperate rainforests provides the only moisture for plants.

Rainforests are often partly self-watering. Plants release water into the atmosphere through a process called transpiration. The moisture helps create the thick cloud cover that hangs over most rainforests. Even when it’s not raining, these clouds keep the rainforest humid and warm.

A tropical rainforest biome is found in hot, humid environments in equatorial climates. In general, tropical rainforests have hot and humid climates where it rains virtually everyday. The level of rainfall depends on the time of year. Temperatures vary through the year – but much less than the rainfall.

It occurs when water droplets from the fog adhere to the needles or leaves of trees or other objects, coalesce into larger drops and then drop to the ground. Fog drip can be an important source of moisture in areas of low rainfall, or in areas that are seasonally dry.

When the moist, warm air makes contact with the cooler surface air, water vapor condenses to create fog. Valley fog forms in mountain valleys, usually during winter. Valley fog develops when mountains prevent the dense air from escaping.

Forests pull in large amounts of water vapor from surrounding regions and from nearby bodies of water. As the vapor condenses into rain, the local atmospheric pressure drops. The whole rainforest-water vapor system is called a biotic pump, because the living forest matter is what’s moving the water.

Rainforests are often called the lungs of the planet for their role in absorbing carbon dioxide, a greenhouse gas, and increasing local humidity. Rainforests also stabilize climate, house incredible amounts of plants and wildlife, and produce nourishing rainfall all around the planet.

As well as the vivid beauty that comes with great diversity in plants and animals, rainforests also play a practical role in keeping our planet healthy. By absorbing carbon dioxide and releasing the oxygen that we depend on for our survival. The absorption of this CO2 also helps to stabilize the Earth’s climate.

Air is sucked in from the oceans which contains moisture. TROPICAL RAINFOREST water goes back into the atmospere causing it to be very moist in the air making it very humid. kind of like when your having a shower or bath and all the steam makes it really hot.

The high rainfall and year-round high temperatures are ideal conditions for vegetation growth. The atmosphere in the tropical rainforest is hot and humid as the result of high temperatures and abundance of water. Subsequently, question is, why is the Amazon rainforest so humid?

On a global scale, long-term fluxes are approximately in balance, so that an undisturbed rainforest would have a small net impact on atmospheric carbon dioxide levels, though they may have other climatic effects (on cloud formation, for example, by recycling water vapour).

On younger substrates, especially of volcanic origin, tropical soils may be quite fertile. If rainforest trees are cleared, rain can accumulate on the exposed soil surfaces, creating run-off, and beginning a process of soil erosion. Eventually, streams and rivers form and flooding becomes possible.
