  1. Karadeniz Ekosisteminde İklimsel Değişimlerin Rolü Temel Oguz oguz@ims.metu.edu.tr http://www.ims.metu.edu.tr/cv/oguz/main.html Ulusal İklim Bilimleri Kollokyumu Nisan 2005, Mersin Oguz (2005), Oceanography, 18(2) METU IMS

  2. Climatic Oscillations Basin-averaged winter (December-March) SST variations • Features: • Long-term warming trend ~0.25oC / 100 years • Variations at multi-decadal time scales (4 phases in ~130 years) • sequence of cold-warm cycles with ~5 years duration

  3. Climatic Oscillations Atmospheric index Ecosystem index All indices exhibit remarkably similar oscillations with sunspot numbers. They are also consistent with the NAO except at few periods. Marine physical climate index Warm years Cold years
