  • Incidence with which the sun’s rays hit the earth’s surfaceAlbedo – surface reflectivity
  • Fragmented penetration = ‘light climates’
  • Evapotranspiration is the sum of evaporation and plant transpiration from the Earth’s land surface to the atmosphere.Interception loss – water evaporates directly back into atmosphere.
  • Less litter, stems and trunks to slow water running away. Normally trap precipitation which then percolates to groundwater systems, so water that is usually recycled is lost in run-off. Transpired water comes from the roots!
