convection
An upward flow of (warm) air is known as a Thermal .
warm air
Warm air molecules move by gaining energy and increasing their speed, leading to expansion and becoming less dense than surrounding cooler air. This causes the warm air to rise and mix with the cooler air in a process called convection.
The upward movement of warm air and the downward movement of cold air forms fluids.
Cold air is denser than warm air, so it tends to sink downward. As it does, it displaces the warmer air, pushing it upward. This creates a convection current where cold air sinks and warm air rises.
The upward movement of warm air is called convection. This process occurs as warm air rises due to its lower density compared to cooler air, creating vertical air currents in the atmosphere.
No. An updraft (updraught) is an upward moving current of warm air.
Warm air rises in thunderstorms because it is less dense than the surrounding cooler air. As warm air rises, it cools and condenses, forming clouds and eventually leading to the development of thunderstorms. This process is driven by convection, where heat energy is transferred vertically through the atmosphere.
