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.
NORTHERN AUSTRALIAN GRASSLANDS. The climate in the Australian grasslands is very tropical. It tends to be an average of 18C (64F) in the winter but temperatures remain well over 28C (80Â° F) in the summer. Australian savannas receive only 18 inches (46 centimeters) of rain a year.The summer is considered the rainy season.s you move from east to west, the rainfall in the prairies decreases. Being located far from the moderating effects of oceans causes a wide range of temperatures, with hot summers and cold winters. The climate of the prairies is also influenced by the sheltering effect of the Rocky Mountains.
