👉 Updrafts are a type of airflow that occurs when air rises above the ground. They are caused by the movement of warm, moist air moving up from a high-pressure system or body of water. The updrafts can be large and powerful, with winds reaching speeds of over 20 miles per hour (32 km/h) in some cases. Updrafts can also cause significant changes to the air quality in areas above them due to the release of pollutants into the atmosphere.

What is the definition of Updraft? 🙋
👉 The term "updraft" refers to the upward movement of air in a plane relative to the ground. This motion is caused by the difference in altitude between the surface and the air above it, which creates pressure differences that cause air to rise. Updrafts are common on high-pressure areas such as mountains or tall buildings, where there is a large amount of air above the ground.
