How does the water cycle affect weather?
Water is constantly being recycled between liquid, solid, and gaseous states
Evaporation – Liquid to gas (forms water vapor)Transpiration – Liquid to gas FROM PLANTS (forms
water vapor)Condensation – Gas to liquid (forms clouds, fog,
dew)Precipitation – Falls from clouds* Runoff – water that flows over land (streams,
rivers)* Infiltration – seeps into the ground (ground water)

How does the water cycle affect weather?
The water cycle can cause a change in humidity, visibility, and precipitation.

How do air masses affect weather?The weather changes when a new air mass
moves into your area.An air mass is a large volume of air in which
temperature and moisture content are nearly the same throughout.
Ex: If we have a warm, humid air mass sitting on our city, we will have warm, humid weather.

How do fronts affect weather?When two air masses meet, a boundary or
FRONT forms.The warm air is forced up, cools and condenses,
forms clouds, and allows for precipitation.Cold front – moves quickly, brings heavy rain,
cooler weather followsWarm front – moves slowly, brings drizzly rain,
warmer weather followsStationary front – doesn’t move, brings
precipitation for many days

How do pressure systems affect weather?
In a high-pressure system, air sinks slowly down.Brings clear skies and calm air or gentle breezes
In a low-pressure system, air rises.As the air rises, it cools, condenses, and forms
cloudsBrings stormy weather
REMEMBER: Winds alwaysblow from a high pressureto a low pressure!

How do global winds affect weather?
Winds are caused by unequal heating of Earth’s surface – which causes air pressure differences – and can occur on a global or on a local scale.
Global winds are:Polar easterlies – cold winds from the poles, blow
EW, 60-90 latitudes Westerlies – blow from WE, 30-60 latitudesTrade winds – blow from EW, 0-30 latitudes
Winds can bring weather that isn’t typical for an area.

How do jet streams affect weather?
Long distance winds that travel above the global winds
They move very quickly in a wavy pattern from WE
Polar jet stream – brings cool, dry air
Subtropical jet stream – brings warm, moist air
Strong storms tend to form along jet streams also

A Summary of the Jet StreamJet streams are strong upper air currents
circumnavigating the globe.There are two main jets: the polar jet and the
subtropical jet.Jet streams can fluctuate in strength between
100-200mph.The jet stream meanders in waves.

How do ocean currents influence weather?
Remember that ocean waters take a lot of energy and time to warm up or to cool down
This helps to moderate temperaturesWinds cause ocean currents on the surface
which can bring cool weather or warm weather to areasEx: Gulf Stream – brings warm water from the
Gulf of Mexico up the east coast of the USEx: East Australian Current – brings warm water
down towards polar regions, FINDING NEMO Sea Turtles used it for transportation
