2 cards from this section. Quick, good the night before a test.
What is net radiation?
Think about how solar energy is received and lost from the surface.
What does albedo refer to?
Consider how much sunlight a surface reflects versus absorbs.
What does net radiation determine in the Penman Equation?
Think about what drives evaporation processes.
True or False: Albedo has no effect on the amount of solar radiation absorbed.
Consider how surfaces vary in reflectivity.
A crop is situated in an area receiving Rs = 30 MJ/m2/day, has an albedo of 0.25, and experiences Rnl = 4 MJ/m2/day. Calculate the net radiation and discuss its implications for evapotranspiration potential.
How does the energy balance impact the water cycle?
In a region with high wind speeds, the saturation vapor pressure is determined to be 3.5 kPa, and the actual vapor pressure is 1.8 kPa. How does this affect the aerodynamic term and thus the overall evapotranspiration?
Analyze the relationship between atmospheric conditions and evapotranspiration rates.
