When a rapidly moving cold air mass runs into a slowly moving warm air mass What is the result and what type of weather will there likely to be?

When a rapidly moving cold air mass runs into a slowly moving warm air mass What is the result and what type of weather will there likely to be?

When a rapidly moving cold air mass runs into a slowly moving warm air mass, the denser cold air slides under the lighter warm air. The warm air is pushed upward along the leading edge of the colder air therefore creating a Cold Front. This forms heavy air or snow.

When a rapidly moving cold air mass runs into a slowly moving warm air mass the result is an?

Name and describe the four fronts. Front- the area where the masses meet but do not mix. Cold Fronts- when a rapidly moving cold air mass runs into a slowly moving air mass, the denser cold air slides under the lighter warm air. Warm Fronts- a moving warm air mass collides with a slowly moving cold air mass.

What happens when a fast-moving cold air mass meets a slow moving warm air mass?

When a rapidly moving cold air mass runs into a slowly moving warm air mass, the denser cold air slides under the lighter warm air. The warm air is pushed upward along the leading edge of the colder air. Warm air (rising) expands and cools.

Which most likely occurs when a fast-moving cold air mass moves into a region of warmer humid air?

Which most likely occurs when a fast-moving cold air mass moves into a region of warmer, moist air? It causes heavy precipitation for a short period of time.

When a fast-moving cold air mass overtakes a slower warm air mass?

When a warm air mass meets and overrides a cold air mass, a warm front forms. The warm air moves up and over the cold and generally brings drizzly precipitation. If a fast-moving cold air mass overtakes a slower-moving warm front and then continues advancing and catches another cold front, an occluded front forms.

Why does cold air move faster than warm air in a cold front?

Cold fronts move faster than warm fronts because cold air is denser, meaning there are more molecules of material in cold air than in 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.

When a faster cold air mass runs into a slower warm air mass a front form?

When a rapidly moving cold air mass runs into a slowly moving warm air mass, the denser cold air slides under the lighter warm air. The warm air is pushed upward along the leading edge of the colder air, as shown in Figure 5. A cold front forms.

What happens to the air masses in a cold front?

A cold front is defined as the transition zone where a cold air mass is replacing a warmer air mass. The air behind a cold front is noticeably colder and drier than the air ahead of it. When a cold front passes through, temperatures can drop more than 15 degrees within the first hour.

What happens when a cold air mass meets a warm air mass?

When a rapidly moving cold air mass runs into a slowly moving warm air mass, the denser cold air slides under the lighter warm air. The warm air is pushed upward along the leading edge of the colder air. Warm air (rising) expands and cools. Rising air reaches dew point and clouds form.

Where does the most complex weather situation occur?

The most complex weather situation occurs at an occluded front, where a warm air mass is caught between two cooler air masses. The denser cool air masses move underneath the less dense warm air mass and push the warm air upward. The two cooler air masses meet in the middle and may mix.

Where do humid air masses form in the winter?

Many summer showers and thunderstorms in the eastern United States develop in air masses that have formed over the Gulf of Mexico. In winter, a humid air mass can bring heavy rain or snow. Maritime Polar Cool, humid air masses form over the icy cold North Pacific and North Atlantic.

Where do large continental polar air masses form?

Large Continental Polar air masses form over central and northern Canada and Alaska. Air masses that form near the Arctic Circle can bring bitterly cold weather with very low humidity. In winter, Continental Polar air masses bring clear, cold, dry air to much of North America.
