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
12 to 33 inches of precipitation a year, mostly in the summer seasons. That is about 30 to 84 cm a year (an Estimate) in summer seasons.
The coniferous forest receives a lot of sunlight each year. Combined with the high rainfall amounts, plants find it the perfect climate in which to thrive. In some areas, the forest can have as much as 18 hours of sunlight per day.
The amount of rainfall in much less.

According to my research the amount of rainfall the rain forest gets each year is about 600cm.

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.
For 25 years
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
Arizona gets an average of 12.7 inches of rain each year.
Not a lot because its in the middle of the Shara Dessert
