Scientists say some people have the ability to smell when rain is coming

Some people claim they can detect rain before it even starts.

Most of Europe may be experiencing a heatwave right now as temperatures saw above the 40 degrees mark, but for those of us in Ireland, it’s all too familiar with the past few weeks of rain. Predicting the outcome of the weather is often foolish, as it's likely to change five minutes later. Some people, however, believe that they are able to detect it before it even arrives.

Scientists say some people have the ability to smell when rain is coming.

Usually, if it rains after a prolonged period of sunshine, you are able to smell rain but now others have said that they can pick up its scent before it has even arrived, while others have dismissed the idea altogether. Yet, with the help of scientific research, it has been revealed that there is evidence to prove some people have the ability to smell the rain before it arrives in what is known as ‘petrichor’. Petrichor originates from the Greek language word 'Petros', which means stone (as in petrify), and ichor, which was the substance that flowed through the veins of the Greek gods. That smell is produced by a solid bacteria known as ‘geosmin’ and the ability to even smell it is considered quite extraordinary given that it is more powerful than a shark's ability to be able to detect blood. You’ll often be able to detect this smell after a spell of rain, as when raindrops hit the ground they flatten out and trap little pockets of air before bubbling up and taking any other chemicals and microorganisms into the air with them. Another chemical, ‘Ozone’, also plays a role in the smell of rain and is much sweeter than petrichor and can sometimes indicate that a storm is on the way. Read more:
