And it comes in hugging the ground. AndMoreAir is more dense than warm air it is heavier than warmer. And it comes in hugging the ground. And so it tends to bow. Like this when cold air is advancing.
What happens when hot and cold air masses meet?
They push against each other along a line called a front. When a warm air mass meets a cold air mass the warm air rises since it is lighter. … On the other hand when a cold air mass catches up with a warm air mass the cold air slides under the warm air and pushes it upward. As it rises the warm air cools rapidly.
What happens when a cold front catches up to a warm front?
An occluded front develops when a cold front catches a warm front. For a maturing cyclone, a warm front is progressing northward ahead of the storm center while a cold front is sweeping southeastward. The cool air mass north of the warm front is already in place.
What kind of rainfall occurs when warm and cold air meet?
Frontal rain Frontal rain is found where warm air meets cold at the cold and warm fronts in a depression (Figure 1).
What happens when two wind fronts converge?
Convergence: When two air masses of the same temperature collide and neither is willing to go back down, the only way to go is up. As the name implies, the two winds converge and rise together in an updraft that often leads to cloud formation.
What happens along a cold front warm front and occluded front?
A warm air mass pushes into a colder air mass (the warm front), and then another cold air mass pushes into the warm air mass (the cold front). Because cold fronts move faster, the cold front is likely to overtake the warm front. This is known as an occluded front.
What happens when the warm air rises at a cold front?
When it meets warmer air a cold front forms and clouds will appear as the warm air rises and then cools. This may lead to heavy rain along the cold front. A warm front forms when warm air advances and meets cold air.
What type of front is formed when cool air cold air and warm air meet?
occluded 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. Occluded fronts usually form around areas of low atmospheric pressure.
Which type of rainfall is produced when a mass of warm and cold air meet Class 7?
Answer: frontal rainfall occurs when warm and cold air meet . 71 percent of the earth's surface is covered with water.
What happens when a cold front meets a cold 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. Occluded fronts usually form around areas of low atmospheric pressure.
What happens in a convergence zone?
A convergence zone in meteorology is a region in the atmosphere where two prevailing flows meet and interact, usually resulting in distinctive weather conditions. This causes a mass accumulation that eventually leads to a vertical movement and to the formation of clouds and precipitation.
What is a cold front advancing under a warm front called?
What is a cold front advancing under a warm front called? A cold front occlusion.
What are the 4 types of weather fronts?
There are four basic types of fronts, and the weather associated with them varies.
- Cold Front. A cold front is the leading edge of a colder air mass. …
- Warm Front. Warm fronts tend to move slower than cold fronts and are the leading edge of warm air moving northward. …
- Stationary Front. …
- Occluded Front.

Which type of rainfall is caused due to the presence of meeting of warm and cold air?
The correct answer is Frontal rainfall. Frontal rainfall occurs when: Two air masses meet, one a warm air mass and one a cold air mass. The lighter, less dense, warm air is forced to rise over the denser, cold air. This causes the warm air to cool and begin to condense.
What happens when warm air collides with a cold front choose all that apply?
What happens when warm air collides with a cold front? Choose all that apply. Warm air forms cumulonimbus clouds and produces thunderstorms. Warm air moves up and over a cold air mass.
What happens to the warm air when it overtakes the cold air in a warm front?
At a warm front, a fast-moving warm air mass overtakes a slowly moving cold air mass. Because cold air is denser than warm air, the warm air moves over the cold air. If the warm air is humid, light rain or snow falls along the front. If the warm air is dry, scattered clouds form.
How ITCZ is formed?
In the northern hemisphere the northeast trade winds converge with southeast winds from the Southern Hemisphere. The point at which the trade winds converge forces the air up into the atmosphere, forming the ITCZ.
What is convergence and divergence in weather?
The terms are usually used to refer specifically to the horizontal inflow (convergence) or outflow (divergence) of air. The convergence of horizontal winds causes air to rise, whereas the divergence of horizontal winds causes downward motion of the air (subsidence).
Can you fly through a cold front?
Some pass by without any weather at all. With these, maybe a shift in the surface wind or a smattering of clouds will mark the front. Aloft, conditions may be so tame that the worst "weather" might be just a few bouts with turbulence, with ceilings and visibilities not being factors.
What is trapped between two cold fronts?
An occluded front occurs when a cold air mass meets another cold air mass trapping a warm air mass on top. This often occurs when a cold front catches up to a warm front. Occluded fronts bring strong wind, clouds, and steady to heavy precipitation. After an occluded front has passed, weather is usually cold and clear.
What is called cyclonic rainfall?
Cyclonic or Frontal rain: This type of rainfall occurs when warm and cold air meets each other. Since warm air is lighter, it rises above the cold air. The rising air is then cooled beyond the saturation point resulting in heavy rainfall. Such rainfall lasts only for few hours.
What is it called when hot and cold air meet?
Warm fronts occur when light, warm air meets cold air. The warm air rises gradually over the cold air as they meet. As the warm air rises it cools and condenses to form clouds. Rain falls along the front as long periods of drizzle or steady rain.
Why is ITCZ called doldrums?
Because the air circulates in an upward direction, there is often little surface wind in the ITCZ. That is why sailors well know that the area can becalm sailing ships for weeks. And that's why they call it the doldrums.
What is the difference between monsoon and ITCZ?
ITCZ – a zonally elongated axis of surface wind confluence of northeasterly (NE) and southeasterly (SE) trade winds in the tropics. Monsoon Trough – the portion of the ITCZ which extends into or through a monsoon circulation, as depicted by a line on a weather map showing the location of minimum sea level pressure.
Does cold air converge or diverge?
Cold air advection also results in convergence of air aloft. This upper level convergence will cause the air to sink and will give generally clear skies. If the winds travel from warm to cold air, we have warm air advection and a ridge will strengthen.
What happens when air diverges?
Divergence occurs when a stronger wind moves away from a weaker wind or when air streams move in opposite directions. When divergence occurs in the upper levels of the atmosphere it leads to rising air.
What are the 4 types of fronts?
There are four different types of weather fronts: cold fronts, warm fronts, stationary fronts, and occluded fronts.
Do cold fronts cause turbulence?
Turbulence is more commonly associated with cold fronts but can be present, to a lesser degree, in a warm front as well. 4. Wind Shear. Wind shear is the change in wind direction and/or wind speed over a specific horizontal or vertical distance.
What is the boundary between cold and warm air masses called?
Fronts Fronts are boundaries between air masses. Depending on the air masses involved and which way the fronts move, fronts can be either warm, cold, stationary, or occluded. In the case of a cold front, a colder, denser air mass lifts the warm, moist air ahead of it.
What is Airfront?
The borderline between two air masses is called a front. There are various types of fronts, including cold, warm, occluded and stationary fronts. A warm front is an area of warm air displacing cold air.
