When two air masses collide, it is called a front.
When a cold air mass replaces a warm air mass, it's called a cold front. Cold fronts typically bring cooler temperatures, higher pressure, and often result in the development of thunderstorms and other weather disturbances.
The air mass that forms over the North Pole is characterized by extremely cold temperatures and high pressure. Known as a polar air mass, it has a stable and dense structure due to the cold air sinking. This air mass often brings cold, dry weather when it moves southward.
A cold front is represented by a blue line with triangles pointing towards the warmer air mass. A warm front is represented by a red line with semi-circles pointing towards the colder air mass. Low pressure is represented by an L on a weather map, while high pressure is represented by an H.
A high pressure system usually produces these conditions in winter. Continental polar (apex)
When a cold air mass moves into an area where a warm air mass is located, it is called a cold front. Cold fronts typically bring cooler temperatures, precipitation, and sometimes thunderstorms as the denser cold air displaces the warmer air.

When a warm air mass is forced into a region of cold air, it becomes denser and sinks below the cold air. This creates a zone of high pressure as the cold air is heavier and exerts more pressure on the surface. The movement of air from high pressure to low pressure causes winds to form.
Pressure differences between warm and cold air masses cause fronts or high/low pressure systems. A warm front is when a warm, moist air mass slides up and over a cold air mass, and a cold front is the opposite.
When a cold air mass replaces a warm air mass, it's called a cold front. Cold fronts typically bring cooler temperatures, higher pressure, and often result in the development of thunderstorms and other weather disturbances.
Humidity is typically low in a continental polar air mass because this air mass originates from high latitudes where the air is cold and dry.

It is called a cold front. Cold air mass is denser than warm air, so when it moves in and pushes existing warm air upward, it creates changes in weather conditions.
