Clouds
Cloud ingredients
water vapor coalescing around a condensation nucleus
The Earth's rotation that makes the winds curve.
What is the Coriolis effect?
The symbol for a cold front is a blue curved line with these shapes on it
triangles
The global wind systems happen basically due to these two phenomena
Coriolis effect and convection currents
The severity of a hurricane is ranked on a scale of _________ to ___________
What is 1-5?
Precipitation will occur when clouds have reached this point
Saturation
A low pressure system (L) means what type of weather is coming?
Stormy with precipitation
A curved red line with semi-circles on it is the symbol this type of weather.
What is a warm front?
The global winds that influence much of our weather in New England
Prevailing Westerlies
I am a big storm that gets my energy from warm ocean waters.
What is a hurricane?
Water vapor needs this (specific vocabulary) to grab onto in order for a cloud to form
What is a condensation nucleus?
Warm air rises over the land, moves to the ocean/sea, then back to the land again.
What is an ocean/sea breeze?
What kind of weather would mT bring?
The area around the equator is known as this due to the northern and southern trade winds colliding
Doldrums or ITCZ (Intertropical Convergence Zone)
I am a cyclone in the South Pacific
What is a typhoon?
A type of cloud that appears as a low gray blanket covering the sky.
What is stratus?
Precipitation that changes from snow, to rain, back to frozen
Sleet
A huge body of air that has similar temperature, humidity, and air pressure at any given height.
What is an air mass?
List the global wind systems in order from the North Pole to the South Pole
polar easterlies
prevailing westerlies
tradewinds

In order for a storm to be considered a blizzard, the winds have to be sustained over _________mph for __________ hours
What is 35 mph over 3 hours
These clouds form and make big thunderstorms.
What are cumulonimbus clouds?
Hail forms under these conditions
updrafts during thunderstorms
precipitation brought upwards beyond freezing zone
precipitation continues to accumulate on the frozen structure until the force of the weight/ gravity is greater than the updraft
A pair of air masses, neither of which is strong enough to replace the other.
What is stationary front?
Rainforests are mostly found in this area of the globe due to the high heat and low pressure often found there
Doldrums/ ITCZ (Intertropical Convergence Zone)
Name two characteristics of a Nor'easter
Form between Georgia and New England
Form between September and April
Form due to cold air (from Canada) and warm air (from Gulf Stream) meeting
