Scientists monitor how rain smells for the first time in history

<p style=";text-align:left;direction:ltr">ArabiaWeather.com - Have you ever had a pleasant smell after it rains? Have you ever thought about the cause of this smell or the physical process that led to its occurrence?</p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> The smell of rain is at its strongest when it rains on dry land or after a long break. The mechanism for the release of this smell from the ground into the air after the rain falls is unknown, according to the scientific definition.</p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> The above video, prepared by a group of scientists in Australia, shows the moment when rain falls at a certain speed that enables us to see what happens when water droplets hit the soil.</p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> It is noted from the video that each raindrop falling on the soil is considered a violent collision, which results in the exit of small air bubbles that move in the air with the wind breeze, which is responsible for the release of the smell.</p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> Scientists are currently studying the possibility of a relationship between the mechanism of the release of the smell of rain and the process of spreading some bacterial diseases after rainfall, especially in the tropics.</p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> <strong>See also:</strong></p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> <a href="http://www.arabiaweather.com/content/بالصور-مناظر-لا-توصف-قطرات-الندى-على-أجساد-الحشرات" target="_blank"><strong>Pictures: Untold scenes.
