Surface winds from tropical Pacific islands - Climatological statistics
Variability space- and time-scales are presently investigated on the basis of multidecadal time series of surface wind observations from islands in the tropical Pacific. The frequency distribution of variance, derived from daily-averaged data, exhibits considerable geographical variation. Poleward of about 5 deg of latitude, the interannual variability in zonal wind diminishes sharply and the zonal and meridional wind variances become increasingly comparable. The zonal wind energy level in the 3- to 60-day band decreases with distance from the equator.
