A cold front occurs when a cool air mass pushes into a warmer one. Since cool air is denser than warm air, the warm air mass gets forced up and over the cooler one. As the air rises it cools, causing moisture in it to condense into clouds and rain.
A cold front is forming.
A maritime tropical or warm, moist air mass.
The location where two different air masses meet is called a front.
Pay close attention to your question. A maritime (meaning oceanic) air mass has moisture, therefore it's not dry. Polar (meaning from the polar region) air mass is cold, therefore it is cold. Hence a maritime polar air mass would be moist and cold...how hard was that?
A cold air mass is a mass of air that has colder characteristics than the surrounding air.
A cold front develops, often resulting in precipitation, and sometimes thunderstorms.
A maritime polar air mass is composed of cold, moist air.
a cold air mass colliding with a hot air mass
It produces lift which if in a moist enough airmass will produce thunderstorms
A maritime polar air mass is characterized as a cold and moist air mass.
A maritime polar air mass is characterized as a cold and moist air mass.
It cools and condenses
A maritime tropical or warm, moist air mass.
cold and moist air mass comes from polar ocean areas
The location where two different air masses meet is called a front.
The warm air mass is forced up and over the cold air mass, resulting in the development of a cold front.
severe weather
If you mean when a mass of cold air meets a mass of warm air, then a front is created.
