This is a warm front.
When a warm air mass moves into an area where a cold air mass is located, it is called a warm front. At a warm front, the warm air mass rises over the cold air mass, leading to gradual temperature increases and cloud formation.
Cold front
The warm air mass is forced up and over the cold air mass, resulting in the development of a cold front.
adibiatic cooling
It keeps moving forward or moves with the cold air it depends
A warm front forms when a warm air mass moves over a cold air mass. As the warm air rises over the denser cold air, it cools and condenses, leading to the development of clouds and precipitation. Warm fronts usually bring steady, light to moderate precipitation and result in gradual weather changes.
The process is known as advection cooling. As the air mass moves over a cold surface, it loses heat energy to the surface through conduction. This causes the air mass to cool down, leading to a decrease in temperature.
Warmer and wetter
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.
Air masses that are cold and forms over polar regions is polar. A cold front occurs when a cold air mass meets and displaces a warm air mass. A front that forms when a warm air mass is trapped between cold air masses and forced to rise is called a occluded front.
A cold humid air mass originating over the North Atlantic or Pacific Ocean is called a "maritime polar" air mass. This type of air mass is characterized by cool temperatures and high humidity, often leading to cloudy conditions and precipitation when it moves over land. Maritime polar air masses can significantly influence weather patterns, especially along coastal regions.
An air mass that forms over northern Canada is typically referred to as a continental polar (cP) air mass. It is characterized by being cold and dry due to its high latitude origins. When this air mass moves southward, it can bring cold temperatures and clear skies to regions further south.
