LAND AND SEA BREEZES
What’s going to heat up faster???
Why???
Think about how the air looks above you. Hot Cold
LOW PRESSURE
HIGH PRESSURE
Air pressure is the same because air temperature is the same.
You have just created lower air pressure
TEMPERATURE:
DENSITY:
PRESSURE:
DIRECTION OF AIR MOVEMENT
BA
COOLER WARMER
HIGHER LOWER
HIGHER LOWER
AIR GO FROM HIGH TO LOW ( A-B)
How, is heat energy being transferred?
CONVECTION CURRENTS
How does this model simulate why we have land and sea breezes. (Include the terms pressure, temperature, specific heat and density in your answer).
How does this model simulate why we have land and sea breezes. (Include the terms pressure, temperature, specific heat and density in your answer).
Land has a lower specific heat than water. Therefore, the land and the air will heat up faster (temperature increases), making the air less dense. This creates low pressure over land and high pressure over water resulting in a:
Sea Breeze
Now let us look at a real life example
Land
HIGH PRESSURE
LOW PRESSURE
AIR GO??
HIGH TO LOW
Water
Land is warmer, therefore the air above the land will be
warmer (low specific heat)
Water is cooler, therefore air above the water will be
cooler (high specific heat)
Land
Land is cooler, therefore the air above the land will be cooler (low specific heat)
Water is warmer, therefore air above the water will be warmer (high specific heat)
LOW PRESSURE
HIGH PRESSURE
AIR GO??
HIGH TO LOW
Water
Land Breeze
