The interaction of large-scale flow and local topography can lead to various meteorological phenomena. A prominent example is foehn, a dry and warm leeward wind. Foehn’s impact on near-surface meteorological parameters and its formation mechanisms have been extensively studied in the Alps and other regions worldwide. However, less attention has bee...
Article
Establishing the link between landslide reactivations and their triggers is one of the key tasks for effective landslide risk assessment. However, to accurately determine the causes of landslides, it is necessary to obtain detailed chronological data on their past occurrences and analyze a larger number of landslides in the area to eliminate local...

Evaporation from open water surfaces is often estimated based on the pan evaporation (Epan), which is an essential measure for estimating atmospheric evaporative demand. Within the Central European region, Epan appears to be slightly underestimated in the case of the hydrological balance of water bodies. In the context of the recent multi-year peri...

Article
An increase in drought frequency, duration and severity is expected for the Central European region as a direct consequence of climate change. This will have profound effects on a number of key sectors (e.g. agriculture, forestry, energy production and tourism) and also affect water resources, biodiversity and the landscape as a whole. However, glo...

Various types of studies require a sufficiently long series of data processed identically over the entire area. For climate analysis, it is necessary that analysed time series are homogeneous, which means that their variations are caused only by variations in weather and climate. Unfortunately, most of the climatological series are inhomogeneous an...

Meteorological and hydrological extremes (MHEs) cause great material damage or even loss of human lives in the present time, similarly as it was in the past. In the Czech Lands (recently the Czech Republic), systematic meteorological and hydrological observations started generally in the latter half of the 19th century. Therefore, in order to creat...

Article
Quality control and homogenization has to be undertaken prior to any data analyses in order to eliminate any erroneous values and non-climatic biases in time series. In recent years, considerable attention was paid to daily data since it can serve, among other conventional climatological analyses, as non-biased input into extreme value analysis, co...

More than 150 landslides originated in the eastern part of the region of the Flysch Outer Western Carpathians in the Czech Republic due to soil saturation caused by antecedent precipitation and long lasting, intensive rainfalls on 16-18 May 2010 (>300 mm as measured by some stations). As a consequence, a multitude of small failures originated, 88%...

In many scientific disciplines it is needed to process long time series of meteorological elements. In recent years considerable attention has been devoted also to analysis of daily data. Prior to any analysis, the need to homogenize data and check their quality arises. Unfortunately, most of the time series of atmospheric data with a resolution of...
