The impacts of Arctic oscillation and the North Sea Caspian pattern on the temperature and precipitation regime in Turkey
WOS: 000495568500004 Arctic oscillation (AO) and the North Sea Caspian pattern (NCP) are atmospheric teleconnections that affect climate parameters such as precipitation, temperature and stream flow. The purpose of this study is to identify the relationship of the AO and NCP with Turkey's mean...
