Climate:
Stability in the atmosphere's natural system in different parts of the glove cause climate and climatic
regions.
Climatic regions may last a long time but aren't permanent/are subject to change over time.
Normal Extreme Weather Event - won't last
Extreme Weather Event -
Patterns of temperature and precipitation combine to form our daily weather. Long term pattern and
variation results in climate.
Air temp varies with latitude, elevation proximity to the ocean, and moisture availability.
Altitude, rather than latitude, is the basis of climate.
More precipitation occurs near the Equator and less in the subtropical regions where there is
pronounced air subsidence. Seasonal variability in precipitation is also important.
Know big differences between climates
More climate types in NH because more land. No D climates in SH ( Cold Midlatitude Climate)
Tropical Climate (A) -
Tropical constantly wet and includes tropical rainforest (Af)
Exists near equator
Little annual variation in temperature and rainfall.
Tropic Wet and Dry (Aw) -
Tropical Savanna; Tropical Monsoon
Savanna has less than 4% of annual precipitation during dry season; Monsoon has more than 4% of
annual precipitation during dry season
Monsoon has extreme heat in the spring.
Savanna has much greater area
Dry Climates (B) -
Deserts (Bw)
Greatest daily temperature range. Very little precipitation.
Under sub-tropical rides; on western side of continents; in rain-shadows of north-south mountain
ranges;
Steppes(Bs)
Adjacent to deserts. Transition areas. Environmentally sensitive.
Prone to desertification.
Warm Midlatitude Climates ( C ) -
Mediterranean (Cs)
Occurs in areas under the influence of subtropical high during high sun period.
Precipitation mostly falls during the low sun season.
Humid Subtropical (Cfa and Cw)
Located on the western side of subtropical highs, centered over ocean where warm moist air blows
poleward
Temp warm. Highest during summer. 20-65" of precipitation
Marine West Coast -
Very mild temperature. Mid to high levels of rain.
