Multiscale Analysis of Antarctic Surface Temperature Series by Empirical Mode Decomposition
International audience This article illustrates the multiscale nature of the Antarctica climatology. Its variability is analyzed from coastal weather stations climate recordings of the continent, supplying temperature data since 1955. Using empirical mode decomposition, coupled to wavelet analysis,...

Summary: | International audience This article illustrates the multiscale nature of the Antarctica climatology. Its variability is analyzed from coastal weather stations climate recordings of the continent, supplying temperature data since 1955. Using empirical mode decomposition, coupled to wavelet analysis, climatological signals are detected of a weak near-8-yr rotating wave that could be the so-called Antarctic Circumpolar Wave. |
