q |
The potential evaporation is defined as the maximum possible
|
|
|
evapotranspiration for the prevailing atmospheric condition.
|
|
|
q |
PE is the amount of moisture the atmosphere demands
based upon its
|
|
energy status.
|
|
|
q |
If there is a higher energy level in the atmosphere, e.g. very high
|
|
|
temperature due to intense solar radiation, it demands more moisture
|
|
|
from the Earth’s surface.
|
|
|
q |
If PE > available evapotranspiration č
leads to dry surface
|
|
|
PE < available
evapotranspiration č leads to runoff.
