“…Indeed, we further showed, for Europe, that frontal precipitation increases with frontal strength. Hence, the upward trend in the number of strong fronts potentially can help to explain the observed regional variations in extreme precipitation over Europe [ Zolina et al ., ; Murawski et al ., ]. Note, however, that frontal storms are only one scenario for extreme precipitation in summer.…”

Evidence is presented that the frequency of extremely strong fronts, which occur mainly in summer, has increased over Europe in ERA‐Interim reanalyses data (1979–2014). Fronts are defined using a common detection scheme based on gradients of equivalent potential temperature (θe) at 850 hPa. The frequency increase is due to increasing atmospheric humidity, which in turn is reported as statistically significant over Europe in the Fifth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC AR5). There is no trend in the frequency of extremely strong fronts in North America where humidity trends are, according to the IPCC AR5, close to zero. Because frontal precipitation increases with frontal strength, measured by the θe gradient, the increase in the number of extremely strong fronts may help explain regional patterns of longer‐term trends in strong precipitation events.

“…The E‐OBS data were used for a complementary analysis over two selected regions, southeastern Germany (SEGE) and CZAT (Figure , blue lines), for the extended period 1959–2015. E‐OBS is heavily affected by smoothing of large‐scale extremes (Hofstra et al ., ) as well as by a strong underestimation of smaller‐scale events (Zolina et al ., ) in regions with low station densities, particularly in the convective summer season. Station density is about 350 km −2 in Germany and about 600 km −2 in the Czech Republic, but much lower in the Austrian Alps.…”

Precipitation patterns over Europe are largely controlled by atmospheric cyclones embedded in the general circulation of the mid‐latitudes. This study evaluates the climatologic features of precipitation for selected regions in central Europe with respect to cyclone track types for 1959–2015, focusing on large‐scale heavy precipitation.The analysis suggests that each of the cyclone track types is connected to a specific pattern of the upper level atmospheric flow, usually characterized by a major trough located over Europe. A dominant upper level cut‐off low (COL) is found over Europe for strong continental (CON) and van Bebber's type (Vb) cyclones which move from the east and southeast into central Europe. Strong Vb cyclones revealed the longest residence times, mainly due to circular propagation paths.The central European cyclone precipitation climate can largely be explained by seasonal track‐type frequency and cyclone intensity; however, additional factors are needed to explain a secondary precipitation maximum in early autumn. The occurrence of large precipitation totals for track events is strongly related to the track type and the region, with the highest value of 45% of all Vb cyclones connected to heavy precipitation in summer over the Czech Republic and eastern Austria. In western Germany, Atlantic winter cyclones are most relevant for heavy precipitation. The analysis of the top 50 precipitation events revealed an outstanding heavy precipitation period from 2006 to 2011 in the Czech Republic, but no gradual long‐term change. The findings help better understand spatio‐temporal variability of heavy precipitation in the context of floods and may be used for evaluating climate models.

“…Researchers from neighboring countries are also interested in the issues of precipitation variability, but it seems that the vast majority of them discuss maximum, extreme, or intense/ heavy rainfall (Kyselý 2009;Hundecha and Bardossy 2005;Zolina et al 2014;Rimkus et al 2011). However, there are also some papers dealing with the variability of average precipitation coming mainly from Germany, but also from countries South and East from Poland.…”

Variability of precipitation in Poland under climate change

The surface warming has been widespread over the entire globe. Central Europe, including Poland, is not an exception. Global temperature increases are accompanied by changes in other climatic variables. Climate change in Poland manifests itself also as change in annual sums of precipitation. They have been slightly growing but, what is more important, seasonal and monthly distributions of precipitation have been also changing. The most visible increases have been observed during colder half-year, especially in March. A decreasing contribution of summer precipitation total (June-August) to the annual total is observed. Climate projections for Poland predict further warming and continuation of already observed changes in the quantity of precipitation as well as its spatial and seasonal distribution.
