American Warming Hole Is Not Unique, In Europe We Also Have Some

Original language description

In our contribution, daily maximum (Tx) and minimum (Tn) temperature at 135 stations in Europe in the period 1961–2000 is analyzed. The cluster analysis indicated 6 and 5 regions for Tx and Tn, respectively, with homogenous trends at stations belonging to one cluster and dissimilar behavior of trends between clusters. The animation of the maps with trends of 30-day sliding seasons with daily step allows one to observe that the European warming hole moves, expands, shifts and disappears during year. Starting in January, a week cooling exists in the Eastern Mediterranean and on the Black sea coast. The cooling of Tn expands to the western Mediterranean around mid-January and to western Europe at the beginning of February. At this time cooling of Tx and Tn also starts in Iceland and grows until its maximum at the beginning of March. Cooling expands again over whole Europe from the end of March until 10th April when almost whole Central and southeastern and partly western Europe experience cooling. This warming hole lasts until the end of April and then it moves to northern and eastern Europe where it culminates around 19th May, being more pronounced for Tn. Next cooling arises over the British Isles at the end of May, expands to Scandinavia and then to northwestern Europe in mid-June and to the Alps at the end of June. The weak cooling remains in central and eastern Europe until the first decade of July, then it moves to eastern Europe at the beginning of August. Cooling rests there and gains strength to show its full power mainly for Tx in mid-September over whole Europe with exception of the most western and northern regions. Cooling of Tx weakens at the end of September but it extends to reach the largest size in mid-October. For Tn, rather a stagnation or weak cooling is detected during the same time. The warming hole retreats from central Europe to the east and really large cooling occurs in the second half of November over eastern and southeastern Europe.
