A cold front forms when a cold, dense air massair massIn meteorology, an air mass is a volume of air defined by its temperature and humidity. Air masses cover many hundreds or thousands of square miles, and adapt to the characteristics of the surface below them. They are classified according to latitude and their continental or maritime source regions.https://en.wikipedia.org › wiki › Air_massAir mass – Wikipedia pushes under a warm, lighter air mass, forcing the warm air to rise. The cold air advances, replacing the warm air at the surface. Rain and even thunderstorms can form as the moisture in the warm air mass rises, cools, and condenses.

What are characteristics of a warm front?
Warm Front Warm fronts typically travel between 10 and 25 miles per hour and contain warm, humid air. As the warm air is lifted, the temperature drops and condensation occurs, forming clouds. Warm fronts typically have a gentle slope, so the warm air rising along the frontal surface is gradual.
What happens when a cold front moves into a warm front?
Because cold fronts move faster, the cold front is likely to overtake the warm front. This is known as an occluded front. At an occluded front, the cold air mass from the cold front meets the cool air that was ahead of the warm front. The warm air rises as these air masses come together.
What Exactly Is A Cold Front?
How do warm and cold fronts interact?
Cold, dense air squeezes its way through the warmer, less-dense air, and lifts the warm air. Because air is lifted instead of being pressed down, the movement of a cold front through a warm front is usually called a low-pressure system. Low-pressure systems often cause severe rainfall or thunderstorms.
What does having a cold front mean?
A cold front is defined as the transition zone where a cold air massair massIn meteorology, an air mass is a volume of air defined by its temperature and humidity. Air masses cover many hundreds or thousands of square miles, and adapt to the characteristics of the surface below them.

Cold fronts generally move from northwest to southeast. The air behind a cold front is noticeably colder and drier than the air ahead of it.
What indicates a cold front?
Cold fronts are depicted by blue line with triangles pointing in the direction of motion. Cold fronts demarcate the leading edge of a cold air massair massIn meteorology, an air mass is a volume of air defined by its temperature and humidity. Air masses cover many hundreds or thousands of square miles, and adapt to the characteristics of the surface below them.

Phrases like "ahead of the front" and "behind of the front" refer to its motion.
What Are Weather Fronts And How Do They Affect Our Weather?
What happens before a cold front hits?
Lifted warm air ahead of the front produces cumulus or cumulonimbus clouds and thunderstorms. As the cold front passes, winds become gusty. There is a sudden drop in temperature, and also heavy rain, sometimes with hail, thunder, and lightning.
What causes a warm front?
A Warm Front forms when a relatively moist, warm air mass slides up and over a cold air mass. As the warm air mass rises, it often condenses into a broad area of clouds. The warm air at the surface, behind the warm front, advances slowly, replacing the cold air at the surface.
Cold Fronts And Warm Fronts
How do you know when a cold front is coming?
If the CirrusCirrusCirrus are wispy clouds made of long strands of ice crystals that are described as feathery, hair-like, or layered in appearance.https://en.wikipedia.org › wiki › Cirrus_cloudCirrus cloud - Wikipedia clouds start to clump together into cirrocumulus clouds. We can now tell that a Cold Front is coming! The Alto Cumulus clouds continued to move downward and form Cumulus clouds, the white puffy ones. And eventually the Cumulus clouds build into Nimbo Cumulus clouds.
What causes warm fronts and cold fronts?
An air massair massIn meteorology, an air mass is a volume of air defined by its temperature and humidity. Air masses cover many hundreds or thousands of square miles, and adapt to the characteristics of the surface below them. They are classified according to latitude and their continental or maritime source regions.https://en.wikipedia.org › wiki › Air_massAir mass - Wikipedia is a large area of the troposphere where the air has a similar temperature and moisture. There are different types of fronts. Cold fronts occur where a cold air mass pushes into a warm air mass. Warm fronts occur where a warm air mass pushes up and over a cold air mass.
