Climatogoly Flashcards
Koeppen’s climatic regions
Equatorial zone Savannah Arid zone Warm temperate Cold and wet temperate The snow/polar
Equatorial wet zone
10 degrees n and s Lowest diurnal variation Lowest temp variations Rains everyday Amazon, borneo tropical rainforests 2 main rainy seasons march, September
Savannah
10 to 20* n and s Depends on ITCZ location 1 wet season in summer but Dry rest of the year, when ITCZ penetrates zone Africa Average temp is around 18* all year
Arid steppe/desert
20*-35* n and s Highest diurnal variation Warm and dry with no clouds or wind Sahara, Arizona, Russian steppe Descending air, subtropical highs Low vegetation due to short wet season
35 to 40* n and s
Warm temperate Warm, dry summers Cold fairly wet winters Mediterranean Hot and dry highs in summer Unsettled frontal lows in winter
Cold/wet temperate
40 - 65* n and s
Dominated by PFD
Uk/New Zealand
Snow/polar zone
Very cold and very dry Tundra frozen soil N Russia, Antarctica, Canada Periods of constant light and dark Can be unsettled in summer due to high PFD moving north
Doldrums
Areas of light winds where the trade winds meet at the ITCZ
Africa in July
South west wet monsoon
Airflow from the subtropical high pressure belt get deflected to the right and hits the western coast of Africa, Nigeria
As the air hits the land it can cause very unstable conditions with lots of convective cloud
South east trades become sw
India in July
South west wet monsoon
High pressure of the Indian Ocean gets deflected to the right when it passes the equator and effects the south west coast of india by creating convective clouds in that location
Se trades become sw
East Asia in July
Same as India and Africa but comes from n Australian high and effects Malaysia/Philippines
N Australia in jan
N Australian n w monsoon
Air from the massive Siberian high get deflected at the equator and head towards n Australia this is helped by the n Australian low also
Ne trades become nw
E Asia and India in jan
Ne dry monsoon
Siberian high sends air over large land masses, not much weather due to travelling over large land masses
Africa in jan
The harmattan is greater and covers more land and therefore making it more dangerous.
ITCZ moves down so does the sub tropical high pressure belt
Polar air outbreak
Cold polar air breaks into lower latitudes that it wouldn’t usual live
Can result in stranded air pools
