The graphs in the Data section are seasonal comparisons for the Coastal Plain, Sandhills, Piedmont, Northern Mountains, Southern Mountains and Outer Banks regions. Each graph displays the differences from the seasonal averages of either temperature or precipitation. Half of the graphs contain 50-year period (1959-2008) and the other half of the graphs contain the eight strongest ENSO years (1966, 1973, 1974, 1976, 1983, 1989, 1992, and 1998).

- For the Outer Banks, the changes in correlation from all years to ENSO years were +0.60 for air temperature and +0.23 for precipitation.

- For the Coastal Plain, the changes in correlations from all years to ENSO years were +0.05 for air temperature and +0.41 for precipitation.

- For the Sandhills, the changes in correlations from all years to ENSO years were +0.40 for air temperature and +0.40 for precipitation.

- For the Piedmont, the changes in correlations from all years to ENSO years were +0.26 for air temperature and +0.07 for precipitation.

- For the Northern Mountains, the changes in correlations from all years to ENSO years were +0.28 for air temperature and +0.03 for precipitation.

- For the Southern Mountains, the changes in correlations from all years to ENSO years were +0.41 for air temperature and +0.05 for precipitation.

Below are the Correlation tables for All Years, ENSO Years, and the change in correlation between the two:
