Air moves up in a thunderstorm because it is wamer and therefore less dense than the surrounding air.

Why do thunderstorms occur during cold fronts?
Coldfronts occur when heavy cold air displaces lighter warm air, pushing it upward. Cumulus clouds form and usually grow into thunderstorms during cold fronts
Why Does a tornado happen when air masses interact?
The tornado is not a direct result of the interacting air masses. When a warm and cold air mass collide the warm air, being less dense, is forced upward. If the warm air mass is unstable enough, this upward forcing triggers the formation of thunderstorms. If other conditions are right, these storms may go on to produce tornadoes.
Why do warm fronts make storms?
A warm front occurs when a warm air mass advances as a cold air mass retreats. As these air masses collide the warm air mass, which is less dense, is forced upward by the cooler air mass. As this happens the air mass cools and the moisture in int condense, forming clouds, precipitation, and sometimes thunderstorms. In many cases warm fronts are associated with rain showers (or snow flurries in the winter). Thunderstorms are more common along cold fronts.
Thunderstorms are likely to form in the warm air ahead of a?
Cold front. When the cold air collides with warm, moist air, the humid air is forced up violently and forms thunderstorms.
When dense cold air meets less dense warmer air the warm air is pushed?
The heavier cold air sinks and slides under the warm air and forces it upward. This causes cumulus and cumulonimbus clouds to form. This brings in the rainstorms and thunderstorms.
When warm air move upward energy is move by?
Temperature
What effect do tornadoes have on the atmosphere?
Tornadoes, as a product of thunderstorms, help stabilize the atmosphere by moving warm air upward.
What is the possible relationship between air temperature and a tornado formation?
Tornadoes are produce my strong thunderstorms. Typically these thunderstorms form along a boundary where cool air pushes into a mass of warm air, forcing it upward.
How do tornadoes affects the atmosphere?
Tornadoes contribute to the role that their parent thunderstorms play in transporting warm, moist air upward.
Why can cold fonts cause thunderstorms?
Thunderstorms start when warm, moist air is lifted and continues to rise on its own. In a cold front, a cooler air mass pushes into a warmer one. Since cool air is denser than warm air, the cooler air mass acts as a wedge, pushing the warmer air up. This can initiate the upward movement needed for thunderstorms.
What storms are produced by large rising columns of warm moist air?
Small area storms formed by the strong upward movement of warm, moist air are called storm surges.
Why do thunderstorms occur during cold fronts?
Coldfronts occur when heavy cold air displaces lighter warm air, pushing it upward. Cumulus clouds form and usually grow into thunderstorms during cold fronts
Why is a thundersnow so rare?
Thunderstorms require the the rapid, upward movement of warm and moist air. These conditions occur rarely when snow is possible.
Why Does a tornado happen when air masses interact?
The tornado is not a direct result of the interacting air masses. When a warm and cold air mass collide the warm air, being less dense, is forced upward. If the warm air mass is unstable enough, this upward forcing triggers the formation of thunderstorms. If other conditions are right, these storms may go on to produce tornadoes.
What process causes the warm air to move upward over the land during the day?
convection
Why do we get a lot of thunderstorms during warm months?
In order for thunderstorms to form the air must be unstable, which generally requires the air near the ground to be warm and moist. This warm, moist air provides the energy that powers thunderstorms. The warmer and more humid the air is, the more energy is available for thunderstorms.
What is an upward flow of air?
An upward flow of (warm) air is known as a Thermal .
