Abstract

The study exploits the air temperature and precipitation data from ERA5-Land reanalysis and E-OBS gridded observations that are freely available from the Copernicus Climate Change Service. The objectives of the study are to analyze the distribution of Köppen climate zones and to detect the changes in the presence and coverage of the specific climate types in Southeastern Europe. The results are shown separately for the following reference periods: 1961–1990, 1971–2000, 1981–2010, and 1991–2020. In the period 1961–1990, the most dominant climate type in Southeastern Europe was fully humid temperate climate with warm summer (Cfb), while fully humid continental climate with warm summer (Dfb) was also highly present there, together with fully humid temperate climate with hot summer (Cfa). In the period 1991–2020, the shift of Köppen climate zones appeared in such a way that the area with Dfb continental climate, that is often called snow or cold climate, is significantly reduced and this type is replaced with Cfb temperate climate. At the same time, Cfa climate type with hot summer is spread across wider area, mainly instead of Cfb with warm summer, now reaching almost the same percentage of coverage as Cfb type.

东南欧柯本气候区的变化探测
这项研究利用了哥白尼气候变化服务免费提供的ERA5-Land再分析和E-OBS网格观测的气温和降水数据。研究的目的是分析柯本气候区的分布,并探测东南欧特定气候类型的存在和覆盖范围的变化。研究结果分别显示了以下参照期的情况:1961-1990 年、1971-2000 年、1981-2010 年和 1991-2020 年。在 1961-1990 年期间,欧洲东南部最主要的气候类型是夏季温暖的完全湿润温带气候(Cfb),而夏季温暖的完全湿润大陆性气候(Dfb)和夏季炎热的完全湿润温带气候(Cfa)也在那里大量存在。在 1991-2020 年期间,柯本气候带出现了变化,Dfb 大陆性气候(通常被称为雪气候或寒冷气候)的地区明显减少,取而代之的是 Cfb 温带气候。与此同时,夏季炎热的 Cfa 气候类型在更广阔的地区分布,主要取代了夏季温暖的 Cfb 气候类型,其覆盖率几乎与 Cfb 气候类型相同。

期刊介绍: Atmospheric Science Letters (ASL) is a wholly Open Access electronic journal. Its aim is to provide a fully peer reviewed publication route for new shorter contributions in the field of atmospheric and closely related sciences. Through its ability to publish shorter contributions more rapidly than conventional journals, ASL offers a framework that promotes new understanding and creates scientific debate - providing a platform for discussing scientific issues and techniques. We encourage the presentation of multi-disciplinary work and contributions that utilise ideas and techniques from parallel areas. We particularly welcome contributions that maximise the visualisation capabilities offered by a purely on-line journal. ASL welcomes papers in the fields of: Dynamical meteorology; Ocean-atmosphere systems; Climate change, variability and impacts; New or improved observations from instrumentation; Hydrometeorology; Numerical weather prediction; Data assimilation and ensemble forecasting; Physical processes of the atmosphere; Land surface-atmosphere systems.
