Not necessarily. A collision of warm and cold air will often produce thunderstorms, but other conditions are needed for those storms to produce tornadoes. Additionally, tornadoes can form from thunderstorms produced by other circumstances.

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 causes fronts?
air masses with different characteristics such as temperature and humidity do not usually mix. so when two different air masses meet a boundary forms between them.
Where do tornadoes occur most often and why?
The greatest number of tornado occur in the United States, particularly on the central plains. The high incidence of tornadoes in tat region has earned it the name "Tornado Alley". This region has an ideal climate setup. Cool air from Canada and dry air from the Rockies frequently meet warm, moist air front the Rockies, giving rise to strong thunderstorms. Wind shear over the region then starts the storms rotating, which allows them to produce tornadoes.
How does a tornado form?
Most tornadoes form in thunderstorms. When the cT and cP air masses meet they create instability in the atmosphere. As the cT air mass start to go up the cP air mass (basically the air) within the updraft tilts the circulating air from horizontal to vertical. The area of the rotation can be 2-6 miles wide and can extend through out the storm.
What happens when a hot cloud and cold cloud meet?
Perhaps there is an equality met.
Why do many natural hazards occur in the Great Plains?
When cold air masses from the north meet warm moist air masses from the south, violent storms can occur.
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 are two types of air masses that occur and how ar air masses related to fronts?
Two types of air masses are cold and warm air masses. When they meet each other, a front forms.
When two air masses meet we normally refer to this as?
A Tornado A Front.
When warm air from a large body of water moves quickly into a land area of cold air we can expect to occur where the two air masses meet.?
A thunderstorm
What happens when warm air masses meet cold air masses?
A warm front forms.
Why does front form?
warm and cold air masses meet
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 kinds of extreme weather occur often in the great plains?
because the region's continental climate creates an environment of extremes.
Where do depressions occur?
Depressions occur in regions where warm air masses meet cold air masses, creating a low-pressure system. This typically happens along the boundaries of large air masses, such as in the mid-latitudes. Depressions can bring stormy weather, including rain, strong winds, and sometimes thunderstorms.
What is formed when air masses meet?
It forms a front, which is a narrow zone. Also, severe weather can occur when two air masses meet. Along a front, precipitation can occur and cause weather changes.
Do Air masses mix at fronts?
Yes,because a warm air mass,and a cool air mass mix together when they meet at fronts.
