We invite studies
* focusing on the understanding and impacts of features of the atmospheric water cycle related to weather systems, such as Atmospheric Rivers, Cold-Air Outbreaks, Warm Conveyor Belts, Tropical Moisture Exports, and the global Monsoon systems;
* investigating the large-scale drivers behind the ongoing and future variability and trends within the atmospheric water cycle, from long-term observations, reanalysis data, regional to global model simulations, or (isotopic) data assimilation;
* involving and connecting field campaigns (YOPP, MOSAiC, (AC)3, ISLAS, EUREC4A, AWACA, LIAISE etc.) with forecast and reanalysis data, indicators of past hydroclimate from climate proxies such as ice cores and stalagmites, and model predictions of the future evolution of the atmospheric water cycle;
* applying methods such as tagged water tracers and Lagrangian moisture source diagnostics to identify source-sink relationships and to evaluate model simulations of the water cycle;
* using the isotopic fingerprint of atmospheric processes and weather systems to obtain new mechanistic insights into changes in the water cycle, to study exchanges between the earth surface and the atmosphere, how convection impacts cloudiness in the tropics, and how the isotopic signal from various archives can be used to reconstruct past climate variations;
* describing the global and regional state of the atmospheric water cycle with characteristics such as the recycling ratio, life time of water vapour, and moisture transport properties.
We particularly encourage contributions to link across neighbouring disciplines, such as atmospheric science, climate, paleoclimate, glaciology, and hydrology.
