The prominence of a tropical convective signal in the wintertime Arctic temperature
Abstract Power spectral analysis reveals that the Arctic temperature averaged over 60°N–90°N oscillates on intraseasonal time scales, centered at about 40 days. We present evidence that this intraseasonal peak is strongly tied to the Madden–Julian Oscillation ( MJO ), the dominant mode of tropical i...
