ГЛОБАЛЬНІ КЛІМАТИЧНІ ЗМІНИ У СВІТОВОМУ ОКЕАНІ ТА ЇХ ВІДГУК В ЧОРНОМУ МОРІ

Abstract

Purpose. By definition of United Nations, global warming and continuous long-term sea-level rise are the most important problems of modern humanity, that are associated with the climate change. This statement can be extended also to Ukraine as a coastal country. The main purpose of this work is about estimation of global trends in the natural processes and identification of the Black Sea level fluctuations’ features in comparison with corresponding trends in the World Ocean. Data & Methods. Researches of changes of the World Ocean’s and Black Sea’s level were carried out by monthly and annual average values for the years 1880-2010, which are presented on the Internet. All our results were analyzed on the scale of the interannual and seasonal variability. Results. The coherence of maximums in the annual variability of mean annual level of the World Ocean and the Black Sea is estimated and their correspondence to El Nino phenomenon is shown. These results reflect trends in the level changing for all the World Ocean and its separate regions. So, the large-scale climatic anomaly affects to the environment by the El Nino phenomenon (which is associated with the planetary waves). Comparison of the level’s changing of the World Ocean and the Black Sea with the global fluctuations of air temperature is conducted; correlation is calculated. The seasonal features of the Black Sea’s level in the 20th century are identified.
