Chapter 12- Mid latitude climates
seasonal temperature change greater than diurnal temp change
I.e., winter to summer temp change is greater than daily min and max temperature ranges
Two major source regions of contrasting air
polar high = cold
subtropical high = cold
Chapter 12- Mid latitude climates
seasonal temperature change greater than diurnal temp change
I.e., winter to summer temp change is greater than daily min and max temperature ranges
Two major source regions of contrasting air
polar high = cold
subtropical high = cold
Mid latitude Temperature rangeMid latitude Temperature range
Circulation is dominated by
Westerlies- eastward motion associated with subtropical jet and polar jet
Rossby waves- undulations in jetstream that enable airmass interaction
Temperature is controlled by
Insolation - higher in latitude the longer the daylight during summer
Airmass origination- where the air gets its characteristics

Most climate categories have several subcategories
Cf ---> has Cfa, Cfb, Cfc, etc.
Wet climates (no dry season)
Climates dominated by sub-polar low pressure and frontal generated precipitation
mid latitude cyclonic storms
Typically located on the southeastern side of continents in Northern Hemisphere
Cfa, Cfb, Cfc climate classifications
Df climates in lower latitudes

Winter dry climates (summer wet)
Generally located in continental interiors
loses effect of moisture from distant oceans during colder months
e.g., northern Great Plains
Mongolia
Typically has extreme seasonal temperature ranges- related to lack of moisture & lat

Continentality- a measure of influence of continental influence on moisture and temperature
Continentality- a measure of influence of continental influence on moisture and temperature
Summer dry climates (winter wet)
Csa, Csb climates- commonly called a Mediterranean Climate as that region experiences this kind of climate
also occurs along western margins of continents at higher latitudes
•effects of oceans strongly influences climates
Locations: California, southern Australia, and near the Mediterranean sea
