Warm air is heated by the sun. Warm air expands and becomes less dense and then the cold air comes in and when the two meet rain and thunderstorms result.
warmer than a cold front and colder than a cold front
the warm air is pushed down because its lees dense than the cold air if cold air is more dense.
Air is heavier in warmer weather than in winter. This is because warm air is less dense than cold air, causing it to weigh more in the same volume compared to cold air.
If a colder air mass actively displaces a warmer air mass at the surface, then it is called as a cold front.That means cold fronts bring cold air into warm areas.In such a condition,the warm air is forced to move upwards resulting in the formation of a low pressure area or depression.If the warmer air mass flows actively upwards(as it is lighter) over the cold mass below, then it is called as a warm front.That means warm fronts bring warm air into cold areas.In such a condition ,the warm air rises gradually over the cold air resulting in the formation of cloud and rain.
When dense,cold air meets less dense,warmer air, the warm air is pushed up
Cold air is denser than warm air, so it tends to sink and move underneath the warmer, lighter air. This creates a pressure difference that causes the cold air to push the warm air out of the way as it moves. This process is known as cold air chasing warm air.
Yes because cold air particles are stuck tight together and warm air particles move around in the air freely. That is why warm air is usually higher up than cold air.
Colder air is more dense than warmer air. That is why nobody every flies in a cold-air balloon.
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.
Cold air is denser than warm air, so it sinks below the warm air, displacing it upwards. This process is called convection, where the warmer air expands and rises as the colder air contracts and sinks.
A warm front occurs when cooler air retreats and warmer air advances. A cold front occurs when cooler air advances, pushing warmer air away. An occluded front occurs when a cold front catches up with a warm front, sending the warmer air aloft. A stationary front occurs when warm and cold air meet, but neither air mass advances.
When dense,cold air meets less dense,warmer air, the warm air is pushed up
