The terminology here is a bit confused. In weather there are 4 basic types of large-scale air mass: Continental polar air masses come off the land in cold regions and are cool and dry. Maritime polar masses come off the ocean and are cool and somewhat moist. Continental tropical air masses come of the land from warm regions and are warm and dry. Finally maritime tropical masses come off of warm oceans and are warm and moist.
When a continental polar air mass pushes into a maritime tropical air mass it forms a cold front. Since cold air is denser than warm air, the tropical air mass is forced upwards. This can trigger thunderstorms. Under the right conditions these storms can produce tornadoes.

What are four types of air masses that affected the US?
maritime polar, continental polar, maritime tropical, and continental tropical
What air mass is indicated by composed of cold dry air?
The Continental Polar is composed of cold dry air.
How are maritime polar and continental polar different?
Continental polar and continental tropical are alike in that they are dry air masses. The different between the two is that the continental polar is a cool air mass while the tropical is a very hot mass of air.
What are the 6 major air masses in the US?
I believe there are only 5 different air masses in the US: 1. Arctic Polar 2. Continental Polar 3. Maritime Polar 4. Continental Tropical 5. Maritime Tropical Hope this helped!
Where do continental polar air masses form?
over northern Canada and Alaska
If both continental Polar and continental Tropical air masses meet does it cause a tornado?
No. If conteinental tropical and continental polar air masses meet, they will form a front. Storm activity would be limited due to the relative lack of moisture. If a continental polar and maritime tropical air mass meet, then thunderstorms are possible. The collision of air masses does not directly result in the formation of tornadoes. Instead, the collisions result in thunderstorms which, if a few other conditions are right, may go on to produce tornadoes.
Can tornadoes form around the world?
Just about. Tornadoes can occur almost anywhere apart from polar regions and extreme desert.
Why cant the continental US have to tornadoes?
The continental United States can and does have tornadoes. It has more tornadoes than anywhere else.
Continental polar air masses form over?
they form over cold dry areas
What are four types of air masses that affected the US?
maritime polar, continental polar, maritime tropical, and continental tropical
Where does a continental polar air masses form?
A continental polar air mass forms over land in northern Canada. A continental polar air mass forms inland from the oceans of Northern Russia, Siberia and Northern Canada.
Where continental polar air masses form?
over northern Canada and Alaska
Where does continental tropical form?
Over land in polar regions that is where it forms I don't know how they form though
Where do continental polar air masses come from?
They form near central and northern canada
What air mass is indicated by composed of cold dry air?
The Continental Polar is composed of cold dry air.
What is an air mass that forms over dry land?
Continental air masses. Tropical air masses form over water.
What continental state has the fewest tornadoes?
Antarctica is not believed to get tornadoes at all.
