Cloud formation in different scales and their impact on water isotope signature

Abstract

The isotopic content of precipitation is an important hydrological tracer and a key element for understanding the water circulation on the Earth and variations in the composition depend on individual atmospheric cooling processes, dynamical and microphysical states of downpour formations, and other factors in cloud formation. This study proposes an algorithm for disaggregation of precipitation types using SYNOP reports of six weather stations in Europe and builds a correlation between convective and stratiform precipitation amounts and atmospheric contents of tritium and stable isotopes.
