What is it called when a cold air mass meets a warm?
The boundary where a cold air mass meets a cool air mass under a warm air mass is called an occluded front.
What happens when a mass of cold air meets a mass of warm air?

Air is more dense thanMoreIt's warm and the warm it's cold. So when cold air comes in because cold. Air 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
What happens when a cold front meets a warm front?
An occluded front forms when a cold front reaches a warm front, forcing all the warm air to rise to higher altitudes and the cold air is stratified near the ground.
What type of front is formed when cool air and warm air meet?
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 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 to the temperature when a warm air mass replaces a cold air mass?
When a warm front passes through, the air becomes noticeably warmer and more humid than it was before. Symbolically, a warm front is represented by a solid line with semicircles pointing towards the colder air and in the direction of movement.
When a warm air mass and a cold air mass meet and no movement occurs?
Stationary Fronts are where a warm air mass and a cold air mass meet but neither have the energy to move under or over the other. Stationary Fronts usually bring Rainy and cloudy weather for many days. NOTES: Occluded Fronts are where a warm air mass is caught between 2 cold air masses.
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 kind of front occurs when a cold air mass replaces a warm air mass?
cold front A cold front is defined as the transition zone where a cold air mass is replacing a warmer air mass. 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 occurs when cold and warm air meet Byjus?
Haze is formed when warm air strikes the cold surface.
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 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.
What happens when two air masses collide?
When two different air masses collide, they don't mix. They push against each other along a line called air front. When a warm air mass meets a cold air mass, the warm air rises as it is lighter and the water vapour in it condenses at higher altitudes.
What’s Convectional rainfall?
Convectional rainfall occurs when the heated air from the earth's surface rises upwards along with the water vapour and gets condensed when it reaches a higher altitude. Here the clouds carrying the water vapour are not carried away by the wind and hence, it rains in the same place.
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.
When cold and warm air masses meet and don’t move?
Stationary Fronts Stationary Fronts are where a warm air mass and a cold air mass meet but neither have the energy to move under or over the other. Stationary Fronts usually bring Rainy and cloudy weather for many days. NOTES: Occluded Fronts are where a warm air mass is caught between 2 cold air masses.
What is 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 convective rain?
Convection Precipitation. Convective precipitation results from the lifting or upward movement of air that is warmer and lighter than its colder denser surroundings (figure 3). Typically, on a hot day the ground surface becomes heated, as does the air in contact with it.
What is precipitation in geography class 11?
What is precipitation? Answer: After the condensation of water vapour, the release of moisture is known as precipitation. This may take place in liquid or solid form. Question 12.
What type of front occurs when a cold air mass runs into a warm air mass from behind?
cold front A cold front forms when a cold air mass runs into a warm air mass (Figure below). The cold air mass moves faster than the warm air mass. So the cold air mass lifts the warm air mass out of its way. As the warm air rises, its water vapor condenses.
What is warm rain called?
Coalescence generally happens most often in clouds above freezing, and is also known as the warm rain process.
How many distinct seasons are found in India as per the Indian Meteorological Department?
four distinct seasons In India as per the Indian Meteorological Department, there are four distinct seasons: Winter Season (from December to February) Summer Season (from March to May) South west monsoon season (from June to September)
What causes rainfall on the coastal areas of Tamil Nadu?
Rainfall in Tamil Nadu is caused by North-East monsoon winds. These winds blow over the Bay of Bengal before hitting the coast of Coromandel, Tamil Nadu. These winds are gathering moisture from the Bay of Bengal and causing Tamil Nadu to flood.
Which type of rainfall occurs when warm and cold air masses meet?
Frontal rain is found where warm air meets cold at the cold and warm fronts in a depression (Figure 1).
Can a cloud burst?
cloudburst, a sudden, very heavy rainfall, usually local in nature and of brief duration. Most so-called cloudbursts occur in connection with thunderstorms. In these storms there are violent uprushes of air, which at times prevent the condensing raindrops from falling to the ground.
What is meant by bursting of monsoon name the place of India which gets the highest rainfall?
Answer: Bursting of monsoon refers to the sudden change in weather conditions during the southwest monsoon, characterized by an abrupt rise in the mean daily rainfall in India during the monsoon season. Mawsynram, located in the crest of Khasi hills in Maghalaya, receives the highest rainfall in the world.
Why North India is so hot?
The main reason for the scorching heat in the northern parts of the country is lack of rainfall. Usually, periods of high temperature are punctuated by periodic episodes of rain but this was largely absent during March and April.
How many distinct seasons are found in India as per the Indian Meteorological Department discuss the weather conditions associated with cold weather season?
In India as per the Indian Meteorological Department, there are four distinct seasons: Winter Season (from December to February) Summer Season (from March to May) South west monsoon season (from June to September)
How do El Nino and Southern Oscillation control the climate of India?
As those conditions change, with the monsoon being linked to El Nino-Southern Oscillation phenomena, summer temperatures over much of India may rise to as high as 45 degrees Celsius, while the Indian Ocean is much cooler.
What are rain bombs?
A rain bomb is a colloquial name for what meteorologists refer to as a wet microburst. When rain from a thunderstorm evaporates before reaching the ground, it's called a microburst. As the air accelerates toward the earth owing to cooling, it cools rapidly. A downdraft is a name for this strong wind.
