A detailed study of the transport of moisture from oceanic and terrestrial sources to the continents can provide a better understanding of the observed changes in the hydrological cycle and some physical support to the results of projections of its future climates. This topic is one of the challenges in the water cycle research.
Subtopics to be included (but not rigorously limited to them) are:
- Global distribution of water vapor: Evaporation and precipitation. Water vapor flux and divergence. Long-Range Transport of Water Vapor.
- Source-Sink Relationships: Methods used to establish source-receptor relationships Analytical or box models, Numerical water vapor tracers, Physical water vapor tracers (isotopes).
- Global source and sink regions of moisture: Oceanic Sources. Terrestrial Sources
- Extreme events: Atmospheric Rivers. Evaporation hot spots. Anomalies of moisture transport linked to drought periods.
- Low level jets, Warm Pools, Monsoons and their role in the transport of moisture.
- The identification and characteristics of moisture sources within the scope of paleoclimatic studies
- Implications of Climate Change: Changes in water vapor. Changes in large-scale circulation related to moisture transport. Changes in precipitation, aridity and soil moisture.
