Tornadoes are not always associated with fronts, but often are. Tornadoes are a product of thunderstorms. Thunderstorms develop when the atmosphere is unstable. In simple terms, that means that a blob of air, when lifted, will continue to rise on its own. But, something needs to give it that initial upward nudge. This is where the fronts come in. Along a cold front, cool air presses into warmer air. Since warm air is less dense, it is forced upward. A similar phenomenon occurs with a warm front, only with warm air pushing into cooler air. Additionally, wind patterns around fronts, especially cold fronts, are sometimes favorable for storms to become strong.

What 2 fronts can cause a tornado?
cold and warm fronts can cause a tornado
What two air masses would most likely form a tornado when they meet?
A cold air mas moving into a warm air mass will create a cold front. It is along a cold front that the severe thunderstorms that can produce tornadoes most often form.
What does cold air do when forming a tornado?
Cold air is not a necessary ingredient in forming tornadoes, but it often plays a role. One of the most common places to find a tornado is ahead of a cold front. A cold front is a boundary where a cool air mass pushes into and replaces a warmer one. Since warm air is less dense than cold air, the warm air mass gets force upwards. If there is enough instability in this air mass, the lift can trigger thunderstorms ahead of the front. Given the right conditions these thunderstorms can start rotating and produce tornadoes.
Do tornadoes happen in cold temperature or warm temperature?
Both. Normally in warm air. However a cold front once came over my house. It was large. It dropped a tornado that I saw with my own eyes. The weirdest thing is I live in California. We get about two tornadoes a year on average and this one almost hits my house.
What fronts are in a tornado?
Fronts do not occur in tornadoes, though they can play a role in tornado formation. Depending on condtions fronts can trigger thunderstorms which, in turn, sometimes produce tornadoes. Cold fronts produce a fair percentage of tornadoes in the U.S. as do dry lines. More rarely they can form along a warm front. Some tornadoes ocurrin storms that develop without a front.
When a cold front catches up to a warm front at the end of a storm?
It could produce a storm, severe storm, or a tornado
What triggers the devolpment of a tornado?
A tonado develops once two different air masses where to meet such as a cold front and a warm front
What type of front forms when a warm air mass is trapped by 2 cold air masses?
Stationary Front
What 2 fronts can cause a tornado?
cold and warm fronts can cause a tornado
What happens when a warm front moves into a cold front?
warm front rises on top of the cold front.
What is the weather along a front?
its is misty and cold on A COLD FRONT AND MUGGY AND WARM ON A WARM FRONT
When warm air rises and cool air sinks in what is it called?
Convection Currents
Does precipitation come before or after a warm front?
Not normally before a warm front, precipitation comes before and after a cold front. When you have warm air and a cold front comes through, you mix warm with cold and that brings precipitation.
Why is a tornado created by both warn front and cold front?
Tornadoes are not formed by the meeting of a cold front and a warm front. There is a bit of confusion here. Tornadoes commonly form where warm and cold air masses collide. Most often along a cold front. In a cold front a cooler air mass pushes into a warmer one. Since cold air is denser than warm air, the warm air mass gets forced up. If this air mass is warm enough and moist enough this upward motion can trigger the formation of strong thunderstorms. If other conditions are right, then those storms may go on to produce tornadoes.
Describe the four major types of fronts?
1) Warm front - warm air mass replacing a cold air mass at ground level. Typically shifts wind southeasterly to southwesterly. 2) Cold front - Cold air replacing warm air at ground level. Tyoically shifts southwesterly to northwesterly 3) Stationary front - Equal amount of energy between warm and cold air masses creating a "stalemate".
What is it called when cold air meets warm air?
tornado
What is an occlude front?
A cold front normally moves at twice the speed of a warm front. An occluded front forms when a cold front catches up with a warm front. Occluded fronts are of two types:1. Cold occlusion : If the airmass of the advancing cold front is colder than the cool airmass of the warm front, the advancing cold front undercuts and lifts both the warm and cool airmass of the warm front. The weather is initially warm front type but during the passage of front, showery weather of cold front occurs. This occlusion is common in summer. 2. Warm occlusion : When the airmass behind the advancing cold front is less colder (cool) than the cold airmass of the warm front ahead, the advancing cold front overrides the warm front ahead. The weather in such a case is similar to that of warm front. This type of occlusion occurs in winters and is less common.
