Winds Part 1
This causes wind
unequal heating of the Earth and the Earth's rotation
Wind is stronger when there are __________ pressure differences.
large
Blow from the sea to the land during the day
Sea breezes
What is a surface current?
found near the surface of the water, driven by wind and energy from the sun
What is the difference between weather and climate?
weather--day to day
climate-long period of time
This is what happens when air currents are deflected as the Earth rotates, changing their path as they move.
The Coriolis Effect
These winds travel from the 30
degree latitude toward the
equator and curve west.
Trade winds
Blow from the land to the sea at night
land breezes
What is a deep ocean current?
moves due to changes in density, found deeper in the ocean
The instrument measures wind speed.
anemometer
This is a fluid that moves from high pressure to low pressure areas
Wind
These winds travel from poles to 60 degree latitude
Polar Easterlies
Sea breezes blow from the sea to the land because the land warms up __________ than the sea during the day.
faster
This is sometimes referred to as a giant or global conveyor belt which moves ocean water.
Thermohaline Circulation
List 3 factors that are factors of global and local weather.
air pressure, wind, temperature, precipitation
Hot air _________ because it is ________ dense.
Cold air _________ because it is ________ dense.
rises, less; sinks, more
These winds form near the equator and your ship could get stuck if you travel through this area
The Doldrums
How do winds affect surface currents?
the wind causes them to start moving
They move in the direction the wind is blowing
Cold, salty water is _________ dense than warm, less salty water.
more
Temperature is most commonly measured using which 2 temperature scales?
Celsius, Fahrenheit
These winds travel towards the Earth’s poles from west to east. They are found between the 30and 60 degree latitude.
Westerlies
These winds form at high altitudes, are high-speed, and travel from west to east.
Jet Streams
How does wind affect climate?
transports heat and water in the air, influencing daily weather patterns as well as overall climate
List 3 differences between surface and deep ocean currents.
surface- cold and warm water, moves quickly, driven by wind, etc.
deep- cold water only, moves slowly, driven by changes in density, temp, and salinity
Warmer, less dense air creates a ___ pressure system while the cooler, more dense air creates a ___ pressure system.
low, high
