Severe Weather
What are the names for a storms like a hurricane in different regions?
Hurricane in Atlantic Ocean
Typhoons in Pacific Ocean
Cyclones in Indian Ocean
What are the three main types of clouds?
What front pushes warm air up and produces lots of rain and thunderstorms?
Cold Front
What is weather?
State of the atmosphere at a specific place and time
Cold are blue triangles and Warm are red semi-circles
What is a hurricane and where does it derive strength?
It is a low pressure system that forms in the ocean with increasing winds.
Warm moist air in the ocean gives it strength and once it hits land it dies down.
Which type of clouds brings lightning, thunder, and tornadoes?
Cumulonimbus
What front produces long but gentle rain showers?
Warm Front
What is humidity/relative humidity?
Humidity is the amount of water vapor present in the air.
Relative humidity is that water vapor measured compared to amount needed for saturation at a specific temperature
What is temperature?
Measure of the motion of molecules
Molecules moving rapidly makes it feel warm so temp is high.
Molecules moving less rapidly feel cold so temp is low.
What is the difference between a warning and a watch?
Watch means that the conditions are favorable for stuff to happen. So stay tuned.
Warning means that the conditions exist so take immediate action
How are clouds made?
Clouds are formed from water vapor that evaporates, condenses, and then clusters together in droplets with dust particles in the sky.
What weather front is the product of two air masses at a standstill and produces clouds, clear skies, and occasional rain?
Stationary Front
What is the Dew Point?
The temperature at which condensation forms.
Name five things to forecast weather
Radar, Weather Balloon, Weather Vane, Satellite, Thermometer, Barometer, Anemometer Wind Sock, etc.
How does a tornado form?
Severe thunderstorms can create a tornado from the base of a cumulonimbus cloud. Wind blowing in different directions and heights produce a wind shear which makes a rotating column of air and the updraft allows it to reach the ground making it a tornado.
What type of cloud is often formed by fog lifting in the morning?
Stratus
What front is the combination of three different air masses/fronts and creates rain and thunderstorms?
Occluded Front
What is an Air mass and Front?
Air mass is a large body of air of uniform temperature and moisture.
A front is a boundary between air masses
How does fog form?
Air is cooled to its dew point on the ground, it forms a stratus cloud called fog
How does lightning and thunder happen?
In a thunderstorm, the movement of air can cause parts of the cloud to be oppositely charged. This current causes lightning.
The rapid heating causes air to expand, cool, and contract rapidly. This movement creates thunder.
Name the three cloud elevation prefixes, 5 clouds, and rank their height
Cirro High Clouds
Alto Middle Height
Strato Low Height
Cirrus, Cirrostratus, Cirrocumulus - High Level
Altocumulus and Altostratus - Mid Level
Stratus and Nimbostratus - Low Level
Cumulus is Low to Mid
Cumulonimbus - Low to Really High
Name and describe all four Weather Fronts
Warm - Long period of gentle rain
Cold - Pushes warm air up and causes thunderstorms
Occluded - Three air masses/fronts and produces thunderstorms
Stationary - Two air masses are at standstill and there is usually clear skies clouds, or light rain
Explain a meteorologist, station model, and weather maps.
Meteorologist is one who studies weather
Station model is a tool that compiles data from the Earth's surface for a specific place.
Weather map is a map that shows data like fronts, pressure areas, temps, isobars, isotherms, and more over a large area.
Finish these precipitation questions
Air is warm so this falls
Air is cold so this falls
Air on ground is cold so this falls
Warm air tosses precipitation up so this falls
Rain
Snow
Sleet
Hail
