Plate 1 Canonical patterns of the spatiotemporal evolution of co-varying 2.2 year LFV peak quasi-biennial (QB) MSLP, surface temperature, and precipitation
signals at 0, 45 and 90 degrees of phase over the domain 65 8 Nto35 8 S from an MTM-SVD analysis using data from 1900 to 1998. MSLP, surface temperature,
and precipitation weights are shown as being redder for positive, and bluer for negative values.
