Rain cycle

Ageing of aerosols in clouds is accompanied by changes in size distribution, surface structure and water content [30,31]. Hydrophilic compounds present in the solid matrix begin to dissolve and rain cycles these species again to...

The advantages of artificial irradiation (weathering) include rapid results, independent of the location, with constant, reproducible radiation intensity, temperature, moisture and constant rain cycles (no arbitrary climate) [214]. Utilizing this... 

Unlike other biogeochemical elements, phosphorus does not have a significant atmospheric reservoir. Thus, while some amount of phosphorus is occasionally dissolved in rain, this does not represent an important link in the phosphorus cycle. River runoff is the primary means of transport between the land surface and oceans, and unlike the other elements discussed. 

They deliver water from the atmosphere to the Earth s surface as rain or snow, and are thus a key step in the hydrologic cycle. 

For both polluted and remote conditions, therefore, the cycling of sulfur from low oxidation state gas to sulfate particles and then back to the surface in rain takes place on a time scale of a few days. 

The evaporite source is characterized by covariation of sulfate (from gypsum) and chloride (from halite). That elements can be recycled from the ocean to land by movement of saltbearing aerosols (so-called "cyclic salts") has confused the interpretation of river flux data somewhat. While this cycling generally follows the ratio of salts in the sea, the S/Cl ratio is an exception. Taking the S/Cl ratio of the cyclic component to be 2 (based on compositional data for marine rains) and assuming that all chloride in rivers is cyclic, an upper limit for the cyclic influence can be calculated.
