NORTH AMERICAN PRAIRIE
As 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. Strong winds blow across the endless plains during both summer and winter.
SOUTH AMERICAN PAMPAS
The climate in the pampas is humid and warm. The average temperature in the Pampas is 18° C. The 'high sun' or dry season is in the summer, which is in December in the Southern Hemisphere. There is wind blowing most of the time.
There isn't much humidity in the air because Steppe is located away from the ocean and close to mountain barriers. The average rainfall is 10-30 inches per year but in May, June, and August, the Steppe can get up to 4-5 inches a month. If it got more rain, it would become a forest. If it got less, it would become a desert. There is also a lot of wind in the Steppe because there are few trees.
Savannas have warm temperatures all year round. There are actually two very different seasons in a savanna; a very long dry season (winter) with temperatures around 21C (70° F) and very little rain, and a very
wet season (summer). The monsoon rains begin in May. It gets hot and very humid during the rainy season.
SOUTH AFRICAN VELDT
The climate of the veld is highly variable, but generally winters from May to September are mild and summers from November to March hot or
very hot. The daily temperatures may vary considerably during the day and there is abundant sunshine. The rainy season is in the summer
months with high-energy thunderstorms.
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 (80° F) in the summer. Australian savannas receive only 18 inches (46 centimeters) of rain a year. The summer is considered the rainy season. Rain clouds form over the savanna as warm, moist air arrives from the equator and strong storms.
