onto the ocean
Term
Where is rainfall the highest?

Term
In the global hydrologic cycle, the majority of the water that evaporates rains down where?

Term
In the global hydrologic cycle, where do the largest amounts of precipitation and evaporation occur?
Definition
in the tropics
Term
Why are annual precipitation totals for the united states are higher in the SE than in the SW, despite similar lats?
Definition
different sea surface temps on the east coast compared to the west, strong subsidence under the substropical high on the west coast, onshore flow on the E coast

lysimeter
Term
In the bucket model of the local water balance, under what circumstance will the delta-s term be negative?
Definition
AE greater than P
Term
How will decreasing the vegetation cover of a place affect the water balance?
Definition
slower runoff rates, leaves and stems catch and use some precipitation before it reaches the surface, the evapotranspiration rates from the soil will increase.
