Abstract

Batumi eddy has a highly dynamic and variable structure. All eddies were identified using a three-dimensional high resolution (1.5km x 1.5km) numerical ocean model. Especially the temporal and spatial variation of eddies larger than 30 km were analyzed in detail to understand how Batumi eddy is changing spatially and temprorally.Batumi eddy is formed by the instabilities of the Rim current during early-mid spring and exist until early autumn in the East Black Sea. Some of the anticyclones that was forced out of the coastal waters by the Rim current turns into filaments to join with the Batumi eddy increasing the strength and size during when the eddy becomes weaker and smaller. The Batumi eddy moves moves slowly north - northwest towards Crimean shore, gets smaller and vanishes. The Batumi eddy exists for around four months and moves with a speed of less then 1 km /day. Most of the passive tracers that are released inside the eddy cannot escape the effect of Batumi eddy during the 4 month life time.

Özet

Doğu Karadeniz’de bulunan Batum döngüsü oldukça dinamik ve değişken bir yapıdadır. Zamansal ve mekânsal olarak değişikliklerin tespit edilmesi için yüksek çözünürlüklü (1.5km x 1.5km) 3 boyutlu bir okyanus modeli kullanılarak Karadeniz üzerinde bulunan tüm döngüler belirlenmiştir. Özellikle 30 km ve daha büyük çaptaki döngülerin detaylı analizi yapılarak Batum döngüsünün zamansal ve mekânsal olarak nasıl değişiklik geçirdiği belirlenmiştir. Batum döngüsü Rim Akıntısı dengesizlikleri sonucu özellikle bahar mevsimi başında ya da ortasında oluşur ve sonbahara kadar Doğu Karadeniz’de varlığını sürdürür. Yaz boyu Rim Akıntısının kıyı sularını zorlayarak üretimine sebep olduğu kıyısal antisiklonlardan bazıları filamentler oluşturarak Batum döngüsüne karışır ve döngünün zayıfladığı dönemlerde genişlemesine ve gücünün artmasına sebep olur. Dönemsel olarak Batum döngüsü yavaş hareketler ile kuzey - kuzey batı yönünde hareketleri sonucu Kırım kıyılarına doğru küçülerek varlığını kaybeder. Döngü varlığını yaklaşık 4 ay sürdürür ve 1 km/gün’den daha yavaş bir hız ile hareket eder. Döngünün içerisinde kalan pasif taşınabilir maddelerin büyük bir çoğunluğunun bu 4 aylık sürede döngünün etkisinden kurtulması mümkün olmamaktadır.
