Where does our water go?

Hypotheses:

  • In which region of North Carolina is the evapotranspiration rate the highest?
  • My hypothesis is that the coastal region will have the highest evapotranspiration rates out of the three main regions.

  • So does the temperature affect the rate of evapotranspiration?
  • My prediction is that it may affect the evapotranspiration rates.

  • Where in specific is the highest and lowest rate of evapotranspiration?
  • From the ECONet stations we pulled data from, I think the station in Aurora, NC, will have the highest evapotranspiration rates because it always seems hot and I think temperature affects evapotranspiration rates. For the lowest rate of evapotranspiration I believe that the station in Oxford, NC, will have the lowest rate of evapotranspiration because it is farther north than most stations we pulled information from.

  • During what time of year is evapotranspiration the highest and lowest?
  • My hypothesis is that during winter the rates would be lower and in summer it would be highest. In addition I would also guess that spring and autumn would be relatively close.

  • What other variables affect the rate of evapotranspiration?
  • Relative Humidity: I think will have a big affect but negative correlation.
  • Solar Radiation: Should be a good correlation and I think it would be positive.
  • Wind Speed: I think the correlation will be low and quite possibly negative.
  • Soil Temperature Average: I think this will have a positive and relatively high correlation.
