CLIMATE 2
Factors affecting climate
Several factors influence climate, contributing to the variations in temperature, precipitation, and other weather patterns. Here are some key factors affecting climate:
Koppen's classification of climate
The Köppen Climate Classification system, developed by climatologist Wladimir Köppen. Köppen's classification is based on a subdivision of terrestrial climates into five major types, which are represented by the capital letters A, B, C, D, and E. Each of these climate types except for B is defined by temperature criteria.
He identified five major climatic groups which correspond with the five principal vegetation groups. They are represented by capital letters as follows:
A type-Tropical rainy climate
I.This is a moist and hot climate.
II.It has average monthly temperature above 18oC.
III.It has heavy rainfall throughout the year which exceeds annual evaporation.
B type-Dry climates
C type-Warm temperature rainy climates (Humid geothermalclimates)
D type-Snowy and cold climates (Cold snow forest climate)
E type-Polar climates (Ice climate)
The five major climatic groups described above are further subdivided into different
sub-groups for each of the climate thus:
Guide to understanding the climatic sub-groups:
The small letters f, s, w and m reflect how seasonal precipitation is and they mean the following:
f = no dry season generally
s = no dry season in summer
w = no dry season in winter
m = moderate dry season in winter and summer.
The capital letters of S and W show the two subdivisions of:
Dry climates.
S = means Steppe or semi desert
W = means desert or arid.
In polar climates
T = means Tundra.
F = means Ice Cap.
Advantages of Köppen's Classification of Climate
Disadvantages of Köppen's Classification of Climate
EVALUATION: 1. Identify t factors that affect climate.
CLASSWORK: As in evaluation
CONCLUSION: The teacher commends the students positively
