Maury et al. 2016 over Canadian Warmings (zoals actueel)
Bericht van: Ruben (Ås, nabij Oslo, Noorwegen) , 02-12-2017 20:35"Canadian warmings. Among the 18 CWs listed by LN00, about 65% (11 CWs) are indeed selected. Note that, because LN00 only report the month where the CWs happened and not the date, theSWEoccurring in November 1966 is considered as the CW occurring in December 1966. The 35% missing are likely due to the fact that CWs are mainly associated with small anomalous temperatures in the lower levels of the stratosphere [Manney et al., 2001]. For instance, CWs in November 1962 and December 1978 are associated with a warm anomaly that occurs below 50 hPa (not shown), while our selection is based on a (pressure-weighted) temperature average between 50 and 10 hPa."
Als ik het goed interpreteer dus niet noodzakelijk sterke opwarming bij deze events. Die lichte warme afwijkingen zie ik ook terug bij de huidige GFS-runs
Overigens nog een leuke grafiek uit dat artikel:
