The process of removing pollutants from the atmosphere by precipitation [i.e. either by rain or snow]. 8, record 1, English, - scavenging%20by%20precipitation
Record number: 1, Textual support number: 1 CONT
Precipitation scavenging is usually divided into two types of process, those associated with cloud phenomena called rainout and those concerned with removal by falling precipitation called washout. It is at present possible to describe theoretically washout processes but no adequate theory of rainout exists. 2, record 1, English, - scavenging%20by%20precipitation

The E-W gradient in the SO4 content in the snow is significant, even after the subtraction of sea-sulphur. A possible explanation may be rainout/washout at the coast of sulphur from distant sources. 4, record 1, English, - scavenging%20by%20precipitation

Rainout (or snowout), which is the in-cloud capture of particulates as condensation nuclei, is one form of scavenging. The other form is washout, the below-cloud capture of particulates and gaseous pollutants by falling raindrops. Large particles are most efficiently removed by washout. Small particles (especially those less than 1 m in diameter) more easily follow the airstream flowing around raindrops and generally avoid capture by raindrops except in heavy rain events. 9, record 1, English, - scavenging%20by%20precipitation

Processus d'élimination des polluants de l'atmosphère par voie humide. 4, record 1, French, - lavage

À l'exception de ce qui reste dans l'air, les SO2 et les NOx retombent au loin de façon ininterrompue, sous forme [...] de dépôts humides : c'est le lavage de gaz et des particules de l'air, par les précipitations (pluie et neige), surtout les orages. 5, record 1, French, - lavage
Record number: 1, Textual support number: 2 CONT
Il semblerait donc que le lessivage de l'atmosphère par la précipitation antérieure diminuait le taux d'acidité. Les périodes pluvieuses caractérisées par des averses et des orages locaux provoquaient des pluies acidifiées. 6, record 1, French, - lavage
