Kruger and Sekele (2013)
Annual mean minimum
Annual mean maximum
Diurnal temperature range
South Africa
Warm extremes increased and cold
extremes decreased for all of the weather
stations
The trends vary on a regional basis, both
in magnitude and statistical significance
Western SA, parts of the northeast and
east of SA, show relatively stronger
increases in warm extremes and
decreases in cold extremes than
elsewhere in the country
79% of the weather stations experienced
increases in warm extremes which is
statistically significant at the 5% level
for maximum temperature
61% of weather stations experienced
significantly negative trends, as for
minimum temperature The strongest
negative trends are found in the north
and east (with a mean of
−2.07% per
decade), the southwestern Cape (with a
mean of
−1.67% per decade), as well as
most of the Northern Cape province
(with a mean of
−1.28% per decade).
