Special Issue related to Fog & Dew 2019 Conference

A Special Issue is currently proposed in the Journal of Hydrology. This special issue will gather contributions based on studies that were presented and discussed at the Fog & Dew conference in Taipei (July 2019) and other relevant contributions.

The title of the special issue is ” Advances in fog and dew life cycles and their dynamics in the hydrological cycle

Special issue presentation:

Fog occurrence spans from arid coastal deserts to high-altitude tropical forests, over mid-latitude continental rural to urban regions, and over seas. Dew, although less observant, also occurs in many continental settings.  Much less is known about direct adsorption of water vapor into the soil.  Fog and dew are important contributors to the hydrological cycle at the interface between the atmosphere and the Earth surface.

Fog, like most types of clouds, results from the combination of many physical processes, including exchange of heat by radiation, sensible and latent heat, mixing of air masses due to mean flow and turbulent motions, and microphysical processes that depend on the chemical and physical nature of condensation nuclei. However, fog life cycle is further complexified through the particularity of the fog layer to be in contact with the surface. Direct exchange of condensed water occurs between the air and the surface generating either dew or deposition of fog.

Dew is fundamentally a result of phase transition, in which water vapor is transformed into liquid when it comes in contact with a surface.  Dew is known to significantly contribute to the hydrological cycle. It has been further suggested that it may contribute to biogeochemical dynamics through promoting microbial activity and nutrient recycling in the upper few centimeters of the soil profile. The lack of potable water in certain arid areas has been at the heart of a renewed interest in dew formation and its possible use to supply water needs.

This special issue invites submissions of the latest research findings from scientists worldwide working on the life cycles of fog and dew at the interface between surface, vegetation and the atmosphere, and on the collection of fog and dew for freshwater production. Its interdisciplinary nature will give this special issue a unique character at the crossroads between fog and dew physics and chemistry and their interactions with and impacts on the hydrological cycle, vegetation, materials, and human activities. The special issue will feature research findings based on in-situ and remote sensing observations of fog and dew dynamics and their impacts on soil and vegetation, high-resolution and numerical weather prediction modeling, equipment design for fog and dew collection, and studies of potability of fog and dew.
