[[4.2 Why seasonal climates and how does the effect vegetation?]]

The Climates:

Mediterranian

Hot Desert

Savanna

Equitorial Climate

Mediterranian:

July= subtropical high pressure leading to hot and dry climate

December = Polar Low Pressure leaidng to warm and wet climate

Hot Desert

July = Subtropical high pressure leading to hot and dry climate

December = Subtropical high pressure leading to hot and dry climate

Savanna

July = Equitorial LowPressure leading to hot and wet climate

December = Subtropical high pressure leading to hot and dry climate

Equitorial Climate

July = Equitorial LowPressure leading to hot and wet climate

December = Equitorial LowPressure leading to hot and wet climate

[[Water Budget Diagrams]]

A: Water Surplus

-Precipitation is greater thanpotential evapotranspiration

- Soil Water store is full

B: Soil Water Utilisation

- p.EVT greater than precipitation

- water store used up by plants

D: Soil Moisture Deficiency

- Soil Moisture store used up

- precipitation absorbed: no run off

- river levels fall/dry up

E: Soil Moisture Recharge

- water stores start to fill

F: Field Capacity reached

- ground water stores used
