Summary
Abstract: [Source: NOAA Climate Prediction Center, http://www.cpc.ncep.noaa.gov/ ]

An extended Empirical Orthogonal Function (EEOF) analysis is applied to pentad velocity potential at 200-hPa for ENSO-neutral and weak ENSO winters (November-April) during 1979-2000. The first EEOF is composed of ten time-lagged patterns . Ten Madden-Julian Oscillation (MJO) indices are constructed by regressing the daily ... View entire text
