Abstract European climate is associated with variability and changes in the mid-latitude atmospheric circulation. In this study, we aim to investigate potential future change circulation over Europe by using EURO-CORDEX regional projections at 0.11° grid mesh. particular, analyze 500-hPa geopotential height (Gph), wind speed mean sea level pressure (MSLP) addressing different warming levels of ...
Introduction Iran country because of great spreading with a view to geographical longitude and latitude‚ existence the contortion of unevenness configuration and locating in exposed of air masses attacking has special circumstances in terms of temporal. The overall structure influenced by latitude‚ altitude and air masses. So that with changing each of these factors the temperatu...
The Mediterranean Sea has been investigated intensively since the early nineties, using modern techniques and collaborative approaches. This overview summarizes some of the resulting advances that were made concerning the physical oceanography of the western Mediterranean. The water mass formation processes are now much better understood and have been quantified to a large extent. The boundary ...
Air-sea-ice interaction processes in the Southern Ocean are investigated utilizing space-observed surface winds, sea ice concentration, and sea surface temperature (SST) from September through December, 1996. The sea ice edge (SIE) shows three ice-extent maxima around the Antarctic during September and October when sea ice coverage is maximum. They are located in the central Indian Ocean, east ...
در مناطق خشک و نیمه خشک تغییرپذیری زمانی و مکانی بارش بسیار بالاست، لذا شناخت عوامل موثر بر بارش این مناطق ازجمله ایران در جهت پیش بینی بارش و مدیریت منابع آب اهمیت ویژ ه ای دارد. نوسانات اقیانوسی- اتمسفری از جمله پدیده النینو نوسانات جنوبی (انسو)، به عنوان یکی از عوامل تأثیرگذار بر بارش مناطق مختلف جهان شناخته شده است. در این مطالعه روابط نوسانات اقیانوسی-اتمسفری مختلف با بارش ماهانه و فصلی ای...
Leiopathes glaberrima is a tall arborescent black coral species structuring important facies of the deep-sea rocky bottoms of the Mediterranean Sea that are severely stifled by fishing activities. At present, however, no morphological in vivo description, ecological characterization, age dating and evaluation of the possible conservation actions have ever been made for any population of this sp...
Mountain systems have an important role on meteorological variations. Different components of the mountain affect the atmospheric parameters and have essential role in atmosphereic circulation. Garmesh wind is one of the most well-known phenomena that are related to mountain systems. In this research, mechanism of garmesh wind are identified using database of garmesh wind in the last 29 y...
The Mediterranean Sea has been defined "under siege" because of intense pressures from multiple human activities; yet there is still insufficient information on the cumulative impact of these stressors on the ecosystem and its resources. We evaluate how the historical (1950-2011) trends of various ecosystems groups/species have been impacted by changes in primary productivity (PP) combined with...
Inter-basin water exchanges can be quite important in climatic-scale numerical studies simulating the circulation and hydrographic characteristics of neighboring oceanic basins connected through narrow straits. The crucial role interaction between Mediterranean Black Seas is often overseen simulations, which rely mostly on parameterizations to describe exchange, essentially decoupling two basin...
An operational model for the prediction of circulation and transport of oil spill in the Black Sea is presented. The hydrodynamic block is developed on the basis of the DieCAST high-resolution low-dissipative model adapted to the Black Sea. The oil spill transport block is constructed on the basis of the random walk approach, which allows predicting motion of individual particles, the assembly ...
