Iată de ce miroase ploaia: explicația din spatele fenomenului

The characteristic fresh smell that arises when rain falls on dry ground is known as 'petrichor', primarily caused by organic compounds released from soil and plants. Geosmin, produced by soil microorganisms, is a key component of this scent. During dry periods, various compounds accumulate on the soil surface, and when rain hits, tiny air bubbles form, releasing these aromatic particles into the air. Humans are highly sensitive to geosmin, allowing us to detect this smell almost immediately after the first raindrops. Ozone, generated during thunderstorms, can also contribute to the fresh scent of rain. The term 'petrichor' derives from Greek words meaning 'stone' and 'liquid', linking it to pleasant memories and emotions associated with rain.
