Updrafts are upward currents of air that rise vertically into the atmosphere, often carrying dust, smoke, or other particles with them. They are created by the heat from the ground or the movement of the air, and can be an important factor in the formation of clouds, storms, and other weather phenomena.<br><br>In aviation, updrafts can be significant for pilots, as they can cause their aircraft to rapidly gain altitude, and in extreme cases, create turbulence or even hazards for takeoff and landing.
