The Arctic Oscillation (AO) effects the climate of the northern
hemisphere. Several previous studies have been shown the effect
of the Arctic Oscillation (AO) on climate conditions in winter in
America, Europe, Asia and the Mediterranean region; Therefore,
this study attempts to investigate the effect of the Arctic
Oscillation (AO) on the mean temperature, As well as the mean
maximum and minimum winter temperatures in Libya (December-
January-February) by analyzing the correlation for 11 stations over
50 years (1961-2010) and testing it statistically. It was found that
the results of the temperature relationship of the winter months are
negatively related between the Arctic Oscillation (AO) and all the
mean temperatures for the winter months in all the study stations,
The study also revealed that the mean January temperature is less
correlated with the AO index than the months of December and
February. The results also indicate that there is a clear spatial
discrepancy with significant statistical significance P-value less
than (0.05) between the correlation of the AO index and the mean
winter temperature in the west, east and south of the country.
Among the results is also that the AO values started to decrease
gradually starting from 1991-2010 in all winter months
(December-January-February). Which led to the tendency of the
mean winter temperature to rise, based on the inverse relationship
of the correlation.
