EXTREME MAXIMUM AND MINIMUM AIR TEMPERATURE IN MEDİTERRANEAN COASTS IN TURKEY
Abstract
In this study, we determined extreme maximum and minimum temperatures in both summer and winter seasons at the stations in the Mediterranean coastal areas of Turkey.
In the study, the data of 24 meteorological stations for the daily maximum and minimum
temperatures of the period from 1970–2010 were used. From this database, a set of four extreme temperature indices applied warm (TX90) and cold (TN10) days and warm spells (WSDI) and cold spell duration (CSDI). The threshold values were calculated for each station to determine the temperatures that were above and below the seasonal norms in winter and summer. The TX90 index displays a positive statistically significant trend, while TN10 display negative nonsignificant trend. The occurrence of warm spells shows statistically significant increasing trend while the cold spells shows significantly decreasing trend over the Mediterranean coastline in Turkey.
