How_can_some_people_Predict_Rain_

There are 2 ways by which rain can be predicted.

First case occurs just before the beginning of heavy rainfall. Here, lightning bolts split nitrogen and oxygen molecules, eventually producing ozone. Now, strong blowing winds, carry ozone downward along with them. Ozone is a sharp smelling gas. When a person smells this ozone, it helps him predict the rain.

Now, the second case occurs when it is already raining somewhere nearby. Usually, surfaces of soil and leaves have aromatic particles of dust and oil on them. When raindrops hit these surfaces, tiny air bubbles containing these aromatic particles are created. Just like fizz rushes upwards in a soda bottle, these air bubbles rush upwards and burst out. Then, gusts of wind carry them ahead of the rain, helping us smell the aromatic particles and predict rain.
