a

Cold Warm Occluded Stationary-Types of Weather Fronts

welcome to moomoomath and science in

this video I'd like to talk about four

types of fronts that create some of our

weather air masses that form from

different areas often do not mix the

reason is that the air masses have

different densities for example warm air

is less dense than cold air so when two

types of air masses meet warm air

generally Rises the area in which the

two types of air masses meet is called a

front the four kinds of fronts are

called cold fronts warm fronts occluded

fronts and stationary fronts in this

demonstration you can see colder

Greenwater move under warmer clear water

and how the warm water moves above the

cold water this is very similar to how

masses of air act up first is a cold

front by cold front forms where cold air

moves under warm air which is less dense

and pushes the warm air up cold fronts

can move quickly and bring thunderstorms

heavy rain or snow cooler weather

usually follows a cold front because the

air mass behind the cold front is cooler

and drier and here's a symbol for a cold

front

a warm front forms where warm air moves

over cold denser air in a warm front

that warm air gradually replaces the

cold air warm fronts generally bring

Drizzy rain and are followed by clear

and warm weather and here's the symbol

for a warm front an occluded front forms

when warm air mass is caught between two

colder air masses the colder air mass

moves under and pushes up the warm air

mass the coldest air mass then moves

forward until it meets a cold air mass

that is warmer and less dense the colder

these two air masses moves under and

pushes up the warm air mass sometimes

though the two colder air masses

an occluded front has cool temperatures

in large amounts of rain and snow and

here's the symbol for an occluded front

and finally a stationary front forms

when a cold air mass meets a warm air

mass however the both air masses do not

have enough force to lift the warm air

mass over the cold air mass so the two

air masses just remain separated this

may happen because there is not enough

wind to keep the air masses pushing

against each other a stationary front

often brings days of cloudy wet weather

and here's the symbol for a stationary

front so there we go for different

fronts that create some of our weather
