Abstract
The Danube River Basin is the second longest catchment basin in Europe and exhibits intense climatological diversity. In recent decades, the frequency and intensity of daily precipitation extremes have suffered from an increment in many parts of the world, including Central and Eastern Europe. Wet spells are defined by the number of consecutive rainy days with different thresholds. The identification of wet spells and their trends in the rainfall time is very important for many sectors, such as agriculture, ecology, hydrology and water resources. Wet spells can lead to extreme events and cause floods and other disasters. In this study, we will attempt to characterise global precipitation in the context of wet spells and associated precipitation depth of wet spells in the Danube River Basin area using daily precipitation data, as well as analysing different approaches to identifying wet spells. The ten most intense wet spells were detected, and the most intense, which occurred on 23 September 1996, was studied in depth in terms of precipitation and associated anomalies, the synoptic situation and the anomalous transport of moisture using a Lagrangian approach. The existence of a marked west-east dipole in the field of sea level pressure between the Atlantic Ocean and the eastern Mediterranean leads to the anomalous moisture transport from the Northern Atlantic Ocean to the Mediterranean Sea, where a higher available amount of moisture existed, and subsequently penetrated within the low positioned over the Danube River Basin. In addition, an Atmospheric River was also responsible for the wet conditions in the Danube River Basin. The combination of all these factors was responsible for the extreme precipitation linked with the wet spell.
Highlights
Extreme precipitation events in Central Europe, including the area inside of the Danube RiverBasin (DRB), have become very common in the last few decades and have usually been associated with related phenomena, such as flooding, landslides, storms, significant material damage and human sacrifices

Summary
Extreme precipitation events in Central Europe, including the area inside of the Danube RiverBasin (DRB), have become very common in the last few decades and have usually been associated with related phenomena, such as flooding, landslides, storms, significant material damage and human sacrifices. Extreme precipitation events in Central Europe, including the area inside of the Danube River. One of the primary causes of extreme weather events may be a consequence of global climate changes [1]. It is known that climate change is one of the major causes of increasing temperatures, precipitation amounts and variability of precipitation events. When the annual precipitation scale is considered, it is clear that those months with the maximum amount of precipitation usually occur during the summer. This phenomenon is especially highlighted in the low-lying part of the Danube River Basin, where convective precipitation makes
