The bold font indicates the most significant correlation in the respective table. Region 1 shows some correlation with SST1 and SST2 when activity is measured with the number of tornadoes, but no correlation when activity is gauged with the number of tornado days. However, tornado days in this Region are somewhat correlated with SST3. The ocean area that typically has the most significant correlations when either strong and violent tornadoes or strong and violent tornado days are considered is SST3. With few exceptions, - values are negative.
Exceptions have z-values too small for statistical significance.
Even the strongest of the correlations are so weak that they have little prognostic value. In order to maintain the original contents of this paper while printing, please do not forget to set your browser to print images as well as text.
