The variability of Antarctic fast ice extent related to tropical sea surface temperature anomalies

Abstract. While numerous studies have examined the influence of meteorological variables on fast ice, the mechanistic linkages between fast-ice variability and large-scale climatic oscillations have remained inadequately explored. Empirical Orthogonal Function (EOF) analysis is applied to circumpolar Antarctic fast-ice extent data (March 2000–February 2018) to investigate seasonal-scale teleconnections between fast ice anomalies and tropical sea surface temperature (SST) variability.
