Tropical Grasslands...Savannas

Tropical grasslands, often called savannas. These are licated inland at or near the equator. The bioms said so. Savannas are in Africa,Right? To tell the truth, I don't know much about this biom. However, this biom is really interesting for me. Because there are a lot of big differences between Savannas and Japanese biom.
Japanese biom is Temperate forests. Generally speaking, there are four seasons in Japan. But, we can see only two sesons in Savannas. That is the wet seasons and the dry seasons. The temperature in there is always hot so the seasons are dicided by rainfall. In Savannas, almost no rain fall during the dry season. This is amazing thing, don't you think??!! We have a lot of rains and snow in Japan. We even have rainy season. There are many words expressing the types of rain. Do you have any ideas? For example, Samidare, Kirisame, and Niwakaame etc. Actually I don't like rainy days. If I visit Savannas, I want to go there in the dry season. I think it is gonna be fun.
As you know, there are so many animals in there. Maybe you have ever watched some document VTR on TV, don't you? I saw many the story of Savannas. Like Lion's child raising and Cheetah's hunting etc. The life in Savannas is really severe...I thought. There is a very big ecosystem in there. If I have a chance to go to Africa, I want to see the real Savannas.
