What conditions are necessary for a cold front?

	Before Passing	While Passing
Temperature	warm	sudden drop
Pressure	falling steadily	minimum, then sharp rise
Clouds	increasing: Ci, Cs and Cb	Cb
Precipitation	short period of showers	heavy rains, sometimes with hail, thunder and lightning

What kind of weather will you associate an approaching cold front with?

As soon as the cold front passes, the weather temperature starts becoming cooler and can drop by 4 degree Celsius or even more. It can also bring rain, thunderstorms or gusty winds. The cold fronts move twice as faster as compared to the warm fronts.

What is a cold front under what conditions do they best develop and what weather conditions are normally associated with them?

The frontal zone, within which the rapid transition from warm to cold air takes place, is narrowest and best defined near Earth’s surface. The cold front is directly related to the polar-front jet stream and usually occurs in close proximity to its core. A cold front is often associated with showers and thunderstorms.

What clouds are associated with cold front?

Cold fronts occur when heavy cold air displaces lighter warm air, pushing it upward. Cumulus clouds are the most common cloud types that are produced by cold fronts. They often grow into cumulonimbus clouds, which produce thunderstorms. Cold fronts can also produce nimbostratus, stratocumulus, and stratus clouds.

What conditions are most likely to prevail after a cold front passes?

Since cold fronts tend to move quickly, they can cause abrupt weather changes, including thunderstorms. After a cold front passes through an area, colder, drier air moves in, often bringing clear skies, a shift in wind, and lower temperatures. Clouds and precipitation also accompany warm fronts.

Why is the cold front associated with severe weather conditions?

Cold fronts often bring very severe weather. This is due to the fact that warm, moist air is less dense than cold, dry air. The warm, moist air is forced upward as the cold front moves in, causing thunderstorms to form.

What causes the weather to be cold?

There are several factors that cause cold weather. Seasonally, winter has the coldest months because the Earth’s tilt is away from the sun. This lowers the angle and amount of solar radiation that reaches the earth’s surface. Wind and moisture also impact how cold the weather feels.

What type of air mass is when cold air sinks?

warm air mass
A cold front is when a cold air mass pushes into a warm air mass. The heavier cold air sinks and slides in under the warm air. The cold air forces the warm air steeply upward along the front. This causes cumulus and cumulonimbus clouds to form.

What happens to air pressure when a cold front passes?

Air pressure usually falls as a cold front approaches, rising rapidly after passage as the dense cold air moves in. The dew point falls indicating the change to a dry air mass.

Why is East Coast so cold?

Land has a lower heat capacity than oceans, and it also heats and cools faster than oceans. During the winter, land is much colder than the oceans. When the westerly winds blow over it, the air cools substantially. Thus, the East Coast experiences extreme cold weather during the winter..
