North Atlantic Oscillation
(NAO) and North Sea Caspian Pattern (NCP) is two of the atmospheric
circulations which are efficient on climate parameters. The purpose of this
study is determining the effects of NAO and NCP on the temperature and
precipitation regime of Mediterranean region in Turkey. In this regard, Pearson
correlation coefficients were calculated between respective atmospheric indices
(NAO, NCP) and climate variables (temperature, precipitation) as annual and
seasonal. The correlation results were assessed according to Student’s t-test.
In this context, it was found that NAO is negatively correlated with
temperature in summer, winter seasons and annual, in addition, NCP has
remarkable negative correlation with temperature data especially in winter,
autumn seasons and annual, as well. As for the linkage between precipitation
and aforementioned atmospheric circulations, it was detected that NAO is
correlated with autumn and winter precipitation negatively, whereas NCP has
negative correlation with winter precipitation and positive correlation with
summer precipitation in some parts of the region. As a result, NAO and NCP have
remarkable influences on temperature and precipitation regime of Mediterranean
region of Turkey for either seasonal or annual.
