A comparison of the averaged weather station datasets versus the historic individual weather station datasets was made for both precipitation and Eto. The averaged monthly dataset preserved seasonality for both precipitation and Eto as illustrated in the figures. Notably, for the months of February, March, and April, the average monthly precipitation volume was lower than the actual weather station historic data. This occurred for two reasons: 1) the disparity in the number of observations between the two weather station datasets and the average resulting in the largest number of observations…show more content… The results of the two test statistics differed at times, i.e., listing two different curves as providing the “best” fit. In the fore-mentioned situation, a final decision pertaining to the “best” fit was made based on a visual assessment of the figures.
Precipitation Events and Eto Levels
The importance of using monthly data instead of annual data for the Salton Sea Basin. Further, the two models: (1) (Logit Y1,……….12) Month = Constant + X1 Prcp, and (2) (Logit Y1,……….12) Month = Constant + X1 Eto, established that some months were significantly different than others concerning the amounts of precipitation and Eto, respectively. The relationships between the duration of precipitation events (‘CatEvent’) on the volume of precipitation (‘PrcpAmt’ and ‘CatVol’), and also on Eto volumes. A plot of the precipitation and Eto observations, percentage or percentage of observations of a given magnitude, respectively, by month was also made.
The negative relationship between precipitation and Eto was tested statistically using two multinomial logistic regression models and one binomial logistic regression model, respectively: (3) (Logit Y0,...4) PrcpAmt = Constant + X1 Eto, (4) (Logit Y0,….5) CatEvent = Constant + X1 Eto, and (5) (Logit Y0,1) RainEvent = Constant + X1 Eto.
