Tropical rainforests lie in the "tropics," between the Tropic of Capricorn and Tropic of Cancer. In this region sunlight strikes Earth at roughly a 90-degree angle resulting in intense solar energy (solar energy diminishes as you move farther north or south). This intensity is due to the consistent day length on the equator: 12 hours a day, 365 days per year (regions away from the equator have days of varying length). This consistent sunlight provides the essential energy necessary to power the forest via photosynthesis.

Because of the ample solar energy, tropical rainforests are usually warm year round with temperatures from about 72-93F (22-34C), although forests at higher elevations, especially cloud forests, may be significantly cooler. The temperature may fluctuate during the year, but in some equatorial forests the average may vary as little as 0.5F (0.3C) throughout the year. Temperatures are generally moderated by cloud cover and high humidity.
For 25 years
A boreal forest typically receives about 20-60 inches (50-150 cm) of rainfall annually. This precipitation is important for sustaining the diverse plant and animal life in the forest ecosystem.
The amount of rainfall in much less.

6-10 In a year
According to my research the amount of rainfall the rain forest gets each year is about 600cm.
A grassland
A forest requires much more rainfall than is found in a desert.
There is no such thing as a 'desert rain forest.' The term is and oxymoron.

Africa is a continent with a wide variety of climatic regions ranging from the Sahara desert to the equatorial rain forest. No single meaningful rainfall number is available.
The answer is 75-150cm per year
Its almost 50000mm in a year
Deciduous forests typically receive an annual rainfall of about 30-60 inches (75-150 cm) per year. This moisture is important for supporting the diverse plant and animal life found in these forest ecosystems.
Arizona gets an average of 12.7 inches of rain each year.
Not a lot because its in the middle of the Shara Dessert
