Many people believe they can smell when it is going to rain, and there is some evidence to support this. When a higher humidity is experienced as a precursor to rain, the pores of rocks and soil become trapped with moisture forcing some of the oils to be released into the air. But the strongest smell is released when rainfall arrives. Raindrops landing on dusty or clay soils trap tiny air bubbles on the surface which then shoot upward - as in a glass of Champagne - and burst out of the drop throwing aerosols of scent into the air where they are then distributed by wind. Release of the scent is most prominent when light/moderate rain falls on sandy or clay soils. During heavy rain, the speed of the drops represses the creation of bubbles stopping the release of aerosols.

Precipitation can wash away odour molecules, making it more difficult to smell. However, some odours, such as petrichor (the scent of rain on dry soil), can be intensified by precipitation. The ease and difficulty of smelling can be influenced by several weather factors, these include the following factors of temperature, humidity, wind and precipitation. Rain, snow, and other forms of precipitation can wash away odour molecules, making it more difficult to smell.
