The Rain Falls Mainly in the...?
News story originally written on September 29, 1997

Tropical rainfall makes up most of the rain that falls on Earth. Tropical rainfall is rain that falls between the latitudes of the Tropic of Cancer and the Tropic of Capricorn. (Do you live in this area?)

Tropical rain is very important for the whole Earth. It affects the weather all over the world.

Scientists are sending into space the TRMM satellite. TRMM stands for Tropical Rainfall Measuring Mission. (Try saying that fast 3 times!) The satellite will be launched November 18, 1997 from Japan.

The TRMM will take very good measurements of tropical rainfall. Hopefully, the TRMM will help scientists figure out how tropical rainfall affects weather around the world. Scientist are also hoping to figure out more about El Nino by taking measurements with the TRMM satellite.
