Rainfall as proxy for evapotranspiration predictions
In this work, we evaluated the relationship between evapotranspiration and precipitation, based on the data recently made available by the Brazilian Meteorological Institute. ETP tend to be lower in rainy periods and vice-versa. This relationship was assessed both in physical and statistical way...

| description | In this work, we evaluated the relationship between
evapotranspiration and precipitation, based on the data recently made
available by the Brazilian Meteorological Institute. ETP tend to be lower in
rainy periods and vice-versa. This relationship was assessed both in
physical and statistical ways, identifying the contribution of each
explaining variable of ETP. We derived regression equations between monthly
rainfall and ETP, which can be useful in studies where ETP time series are
not available, such as reservoir design, irrigation management and flow
forecast. |
