Importance of late fall ENSO teleconnection in the Euro-Atlantic sector King, Martin P.

Here, we present some exploratory analyses using observational data and seasonal hindcasts, with the aim of highlighting the potential of the El Niño-Southern Oscillation (ENSO) as a driver of climate variability during boreal late fall/early winter (November/December) in the North Atlantic-European sector and motivating further research on this relatively unexplored topic. The atmospheric ENSO teleconnection in November/December is reminiscent of the East Atlantic pattern and distinct from the well-known arching extratropical Rossby wavetrain found from January to March. Temperature and precipitation over Europe in November are positively correlated with the Niño3.4 index, which suggests a potentially important ENSO climate impact during late fall. In particular, the ENSO-related temperature anomaly extends over a much larger area than during the subsequent winter month 2018-09-26T16:25:38Z 2018-09-26T16:25:38Z 2018-07-23 2018-09-26T16:25:38Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion 0003-0007 https://hdl.handle.net/2445/124852 676087 eng Reproducció del document publicat a: https://doi.org/10.1175/BAMS-D-17-0020.1 Bulletin of the American Meteorological Society, 2018, vol. 99, num. 7, p. 1337-1343 https://doi.org/10.1175/BAMS-D-17-0020.1 (c) American Meteorological Society, 2018 info:eu-repo/semantics/openAccess 7 p. application/pdf American Meteorological Society Articles publicats en revistes (Física Aplicada)
