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.
Savannas have two seasons, a very dry one and a very wet one. The average temperature is about 20-30 degrees Celsius (summer). The winter temperature is about 20-25 degrees Celsius and the summer is 25-30 degrees Celsius. The summer is wet while the winter is dry. Another type of grassland is called a temperate grassland. There are also only two seasons, with summers from warm to hot, and winters from cold to freezing.
