Abstract

           This paper analyzes the role of climatological variations and effects of El Niño, La Nina and the North Atlantic Oscillation (NAO) on cloud cover and the role of cloud cover on thermal potential in selected areas in Turkey.  Positive anomalies in the NAO and the strongest La Nina years (weakest El Niño years) correspond with decreasing trends of cloud cover values (increasing probability of dry thermals).  This study utilizes 1D wavelet packets and continuous wavelets on historical cloud cover values in northwestern and central parts of Turkey.  The results show a role of cloud cover variations on thermal structure and soaring potential of the study area over last 35 years and favorable soaring conditions with wet thermals in the next decade.
