Fig 1.
Geographical configuration of the temperature deviations from the mean during an El Niño event.
Counties in orange experience a temperature increase, while the counties in blue are generally cooler during an El Niño episode. Affected counties are classified based on information gathered from the National Oceanic and Atmospheric Administration (NOAA).

Effects of El Niño-induced changes in temperature on inland salinity.
Fig 2.
Difference between average soil salinity levels during El Niño years and neutral years.
Orange stands for a positive difference between El Niño years and Neutral years, i.e. there is an increase of soil salinity levels, while blue denotes counties that exhibit a negative difference, i.e. soil salinity levels decline.
Fig 3.
Proportion of counties that experience, on average, an increase in salinity levels during El Niño years, divided by geographical areas.
A: Percentage of counties that experience an increase in soil salinity during El Niño is higher in counties with a positive deviation from mean temperatures. B: Percentage of counties that experience an increase in water salinity during El Niño is higher in counties with a positive deviation from mean temperatures.
