Dr. Elemér László is a researcher working in the fields of hydrology, hydrogeology, and isotope hydrology, with a particular interest in the application of stable and radioactive isotopes to investigate processes within the hydrological cycle. His research focuses on the isotopic composition of precipitation, including δ²H, δ¹⁸O, tritium (³H), and deuterium excess, and their relationships with atmospheric and meteorological processes. His work also addresses the effects of convective and stratiform precipitation, below-cloud evaporation, and regional climatic conditions on precipitation isotope characteristics in Central Europe and the Carpathian Basin. He has experience in analysing long-term isotope monitoring datasets and integrating isotope observations with meteorological data to better understand atmospheric–hydrological interactions and water-cycle processes.
