    • The MJO index (the first PC) was normalized to unit variance for use in this figure. Positive values of the index correspond to westerly wind periods. The MJO index has zero mean and includes 1035 positive pentads and 1119 negative pentads. The number of genesis events during westerly periods of amplitude greater than one is significantly higher than the number during easterly periods of the same amplitude at the 95% confidence level.
