1.7 Factors that Affect Climate
climate
temperature
humidity and precipitation
mountains near ocens interfier winds and affect precipitation
monsoons: winds that bring heavy rains
vague: description of annual norm
detailed: month by month averages
geographical factors: altitude, latitude, prevailing winds, proximity to the ocean, ocean currents
winds: wind is the movement of air parallel to Erths surface
high to low until equalized
radiaition, conduction and convection
heat rises during convection
air cools as it rises and spreads out in the atmosphere
the coriolis effect: allows wind to move between east and west
earths rotation
wind can blow in and direction this is due to local winds
however prevaling winds are from one direction
polar or equatorial oceanic or continental
affect temp
and humidity
less dense sinks back down
lower density: where hot air rises
hence wind and convection currents
seasonal winds
prevaling winds might not come from the same direciton all year
are marked by seasons
Sea breeze: during the day air over land is warmer rises and creates low pressure which cool winds flows
land breeze: during the night the air above the land is now cooler that the air above the sea
ocean currents
surface ocean currents are streams of ocean water that move through the oceans in regular patterns, caused by winds
warm currents: from tropics to pola
cold currents: bring cold water from the pole
equatoral currents: heat up coastal lands
polar currents: cool down coastal lands
