Series Graph 3

aa (Coefficient of Evaporation Change) = 0.04

bb (Coefficient of Precipitation) = 0.01 (Constant)

yy (Magnitude of Evaporation Change) = 0.01

 

xx (Delayed Timing of Peak Evaporation Change) = pi/2 = 0 days

The onset of peak evaporation is the same as the onset of peak precipitation. The magnitude of the evaporation change was raised which produced a higher rate of evaporation during the growing seasons. The large red area between the upper evaporation curve and the lower precipitation curve shows a large deficit resulting in a reduction of 29% in the crop yield.

 

xx (Delayed Timing of Peak Evaporation Change) = 9*pi/16 = 15 days

The onset of peak evaporation is 15 days after the peak precipitation. The magnitude of the evaporation change was raised which produced a higher rate of evaporation during the growing seasons. This allows for a larger deficit area due to slight increase in evaporation at the beginning of the growing season during a decreasing period of precipitation. There is a reduction of 42% in the crop yield.

 

xx (Delayed Timing of Peak Evaporation Change) = 2*pi/3 = 30 days

The onset of peak evaporation is 30 days later than the peak precipitation. The magnitude of the evaporation change was raised which produced a higher rate of evaporation during the growing seasons. This shift leads to a slight surplus (blue) at the end of the growing season and a larger deficit (red) at the beginning of the growing season. There is a reduction of 65% in the crop yield.

 

xx (Delayed Timing of Peak Evaporation Change) = 3*pi/4 = 45 days

The onset of peak evaporation is 45 days later than the peak precipitation. The magnitude of the evaporation change was raised which produced a higher rate of evaporation during the growing seasons. Note that the deficit area is growing as compared to the previous graph. There was a reduction of 82% in the crop yield.

 

xx (Delayed Timing of Peak Evaporation Change) = pi = 90 days

The onset of peak evaporation is 90 days later than the peak precipitation. The magnitude of the evaporation change was raised which produced a higher rate of evaporation during the growing seasons. There is a small area of surplus, but the large area of deficit late in the growing season outweighs this area. There was a reduction of 114% in the crop yield. THIS CROP WAS A TOTAL LOSS.
