• Description:
  Over the period Decem-ber 2013–February 2014, there was a pronounced reduction of extratropical storm (ETS) activity over the North Pacific Ocean and the west coast of the United States of America (USA), and a substantial increase of ETS activity extending from central Canada down to the midwestern USA (Fig. 6.1a). The ETS activity was measured by the standard deviation of filtered 6-hourly sea level pressure in December–Febru-ary (DJF) using a 24-hour-difference filter (Wallace et al. 1988). A number of large-scale climate factors could have inf luenced the probability of this ex-treme year. Natural climate variations, such as the El Niño–Southern Oscilla-tion (ENSO) and the North Atlantic Os-cillation (NAO) significantly inf luence ETS activity over North America (e.g., Yang et al. 2015; Grise et al. 2013). Our assessment of these factors indicates that they were not major players in the 2013/14 case (not shown).
