Ocean’s affect on
Weather
Sea Breezes & Hurricanes
Sea
Breezes
Cause:
• The Sun’s energy heats the
Earth unevenly.
• Land heats up faster than the
water in the ocean.
Cause:
• The warmth of the land heats
the air above it causing the
warmed air to rise.
• Cooler air above the ocean
moves in over the land to take
the place of the warmed air that
rose upward.
Cause:
• As the warm air rises it begins
to cool.
• The water vapor in the warm air
condenses to form clouds.
• The cooled air sinks back
towards the Earth.
Sea Breeze
Effect:
• A convection current is created
in the atmosphere over the
ocean and land.
• This creates a sea breeze or
wind blowing in towards the
land from the ocean.
• Water vapor in the air
condenses forming clouds.
Hurricanes
Cause
:
• #1 - Ocean provides warm,
moist air that rises.
• #2 - Winds coming toward each
other spiral & force the air
upward.
Cause:
• #3 - Winds at the top flow
outward above the storm
allowing air from below to rise
• #4 - Humid air rises & makes
the storm clouds
• #5 - Light winds outside the
hurricane steer it and let it grow
Convection Current
Effect:
• Convection currents within the
storm
• Hurricanes start off of the west
coast of Africa
• They move counter clockwise
towards the Gulf of Mexico or
the east coast of America
North
