Tropical (Equatorial) Rain Forest(TRF) Conditions Constraints vs. Opportunities
What are the locational characteristics of TRF? • at equator • around 5 degrees north or south • occasionally extends to 20 degrees
Atmospheric Conditions • Heavy precipitation (around 3000mm/year) • convectional rainfall • high temperature • lack of seasonality • small annual range of temperature
Hydrospheric Conditions • Large discharge and large baseflow • Large underground flow Heavy precipitation Why?
Soil • Oxisol • fine texture Why? Answer: chemical weathering • infertile and slightly acidic Why? Answer: Precipitation > Evaporation • heavy leaching Why? Answer: Precipitation > Evaporation • hard pan
