Seasonal Rainfall and ENSO over the Tropical Pacific Region
Luke He, NOAA/NWS/NCEP, Camp Springs, MD; and E. Olenic and D. A. Unger
During the last decade, the demand for climate information in the
tropical Pacific region has risen greatly. The potential utility of
climate information on many of the populated tropical Pacific islands
is clear, giving their agricultural and otherwise water-dependent
economics. Rainfall data (1955-2007) has been used to study some
statistics on seasonal rainfall anomalies, the frequency and intensity
of drought episodes and the effect of El Nino Southern Oscillation (ENSO) on Hawaii and US-affiliated islands. The influence of ENSO episodes on Hawaii and US-affiliated islands is described in greater detail using composite analysis, in which responses to warm ENSO episodes are considered separately from responses to cold episodes. Results have shown that short term global climate fluctuations, such as those related to ENSO phenomenon, play a dominant role in the climate variability in the tropical Pacific region.
