Effects of ENSO on Autumn Rainfall in Central Vietnam

Table 4

The probability ( value) associated with Student’s -test for El Niño, La Niña, and ENSO-neutral conditions compared to climatology for rainfall, relative vorticity, and sea level pressure. Columns 4 and 5 indicate the statistical significance at 95% and 90% confidence levels, respectively. A YES means that the difference between mean values in an ENSO condition and climatology is statistically significant.
