EFFECTS OF EL NIÑO/SOUTHERN OSCILLATION ON HYDROLOGICAL CONDITIONS IN NORTH CAROLINA
We compiled up to 56 years of precipitation and streamflow data from monitoring stations across North Carolina and surrounding states. We compared seasonal trends in these data to the Multivariate ENSO Index (MEI). Correlation analysis indicates that ENSO conditions influence precipitation significantly in North Carolina, and that the magnitude of this influence is greatest along the southern Atlantic coast and decreases with distance inland. We applied similar statistical analyses to streamflow data to determine whether hydrological variables exhibit a similar response to ENSO. These results have implications for understanding interannual fluctuations in hydrological variables in the southeastern US.
