The hosts discuss the nature of wind, exploring ideas about air pressure differences, the influence of gravity and water, and the distinct smell of rain called petrichor. They debate the role of barometers and air density in the creation of wind.
Wind is caused by differences in air pressure.
The smell of rain is called petrichor and is caused by a combination of water, ozone, geosmin, and plant oils.
Air pressure, density, and humidity play a role in wind patterns.
