In the African tropical savannah, there is both a rainy season and a dry season. The rainy season is about 6-8 months of the year. It lasts from May to November in the southern hemisphere, and September to March in the northern hemisphere. During the rainy season, floods often occur due to a large amount of rainfall. There can be as much as 47 inches of rainfall during the rainy season, and the dry season receives less than 4 inches! The yearly amount of rainfall is 50 inches at maximum, and 30 inches at minimum.
The dry season is slightly shorter than the rainy season. It lasts from October to march in the southern hemisphere, and April to September in the northern hemisphere. Because the dry season only gets 3 inches of rainfall, it is a time of drought. During such a dry season, sometimes fires will appear out of nowhere! The savannah is one of the few climates in which both floods and wildfires may occur.
Floods, drought, and wildfires may seem extremely dangerous, but they actually help the living factors, such as the plants, by getting rid of the old plants so new ones can grow. Since the dry season is only in one hemisphere at a time, elephants will migrate during the dry season to stay away from the drought and wildfires.

wow Grant. You look great up there giving your presentation.
Grant, Grampie and I are very impressed by your report! We also noticed you're wearing one of Grampie's favorite things...the flannel shirt.
