A platelet count below 150,000 per mcL is called thrombocytopenia, while a platelet count over 450,000 is called thrombocytosis. Platelets seem to have a large backup capacity: blood typically still clots normally as long as the platelet count is above 50,000 per mcL (assuming no other problems are present).
Tropical savanna climates are most commonly found in Africa, Asia and South America. The climate is also prevalent in sections of Central America, northern Australia and southern North America, specifically in sections of Mexico and the state of Florida in the United States.n essence, a tropical savanna climate tends to either see less rainfall than a tropical monsoon climate or have more pronounced dry seasons. There are generally four types of tropical savanna climate: 1  One form of the tropical savanna climate features distinct wet and dry seasons of relatively equal duration.
Savanna is grassland with scattered individual trees. Savannas of one sort or another cover almost half the surface of Africa (about five million square miles, generally central Africa) and large areas of Australia, South America, and India.recipitation in the temperate grasslands usually occurs in the late spring and early summer. The annual average is about 50.8 to 88.9 cm (20-35 inches). The temperature range is very large over the course of the year.
