Amazon Rainforest Overview |
- Amazon in South America is 6milliom km2
- Tall evergreen, Hardwood Trees |
|
|
Water Cycle Features |
- High average annual temperatures between 25C and 30C - Small seasonal variation in temperature - High average annual rainfall (2000mm) no dry seasons |
|
|
Temperature |
- High average temperatures due to intense insolation - Wide cloud coverage ensuring no extreme temperatures (direct solar radiation) - Seasonal differences hardly affect temperature - 50-60% precipitation recycled by evapotranspiration
|
|
|
Precipitation |
- 2000mm> rainfall evenly distributed through out the year - High moisture (humidity) and dense vegetation - This feedback loop sustains high rainfall - Most evaporation by result of leaf interception - Moisture lost in transpiration by roots in the soil |
|
|
Run Off |
- Rapid run-off due to high rainfall and well drained soils - River discharge may peak in 1 or 2 months |
|
|
Atmosphere |
- High temperatures allow the atmosphere to store large amounts of moisture - Relative discharge may peak in 1 or 2 months |
|
|
Soil/Groundwater |
- Abundant rainfall leads to significant water storage soils and aquifers |
