Science -- climate/oceans

POLAR

→Extremely cold(Only 2 to 4 months above freezing)

→ Cool summers and temps less than 50 f

→ Dry year round

SEVERE

→Very cold winters, at least one month averages below 26 degrees → Warm summers, temps above 50 f → Varys in precipitation

HIGHLAND

→Cold to cool temps 

→ Temps range from -2 to 50 degrees f

→ Varys

MILD

→cool winters

→ Warm hot summers

varys

DRY

→Hot days cold night

→ Summer temp reach a maximum of summer temps above 88

→ Dry year round

TROPICAL

→Hot year round

→ wet

→ above 64 degrees

Surface ocean Currents

Moved by wind and the rotation of the earth(coriolis effect)

→ Warm or cold depending on place of origin

Winds

→ Global winds move surface currents of the ocean

→ Currents move in the same directions as winds

→ Winds help move warm water from the tropics to polar regions.

The Coriolis Effect

 Due to the constant rotation of the Earth, surface ocean currents move in a circular direction.

→ These are called Gyres

Northern hemisphere - clockwise

Southern hemisphere - counterclockwise

Polar Easterlies

• Found between 60 and 90 degrees

• Start in the east and move west from high and low pressure

Westerlies

• Found between 30 and 60 degrees

• Start in the west and move west from high and low pressure

Trade Winds

• Found between 0 and 30 degrees North and South

• Start in the east and move west from the high to low pressure.
