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 data onto the ten patterns of the first EEOF. Data is available for the ten MJO indices (normalized) for the previous 6 and 12 months. The MJO Indices are centered at 20E, 70E, 80E, 100E 120E, 140E, 160E, 120W, 40W and 10W indicating centers of enhanced convection for the ten indices, which are determined from the ten time-lagged patterns of the first EEOF of CHI200. Anomalies are based on the 1979-1995 period, and each index is normalized by its standard deviation during ENSO-neutral and weak ENSO winters (November-April) in 1979-2000. Pentad MJO indices are available since 1978.
