Heavy and torrential rains are one of the hazardous phenomena of atmosphere which always cause several severe damages over Iran. For this reason in every developmental program their intensity and frequency should be understood and predicted. The main factor to their development and intensification are the atmospheric pressure patterns and motions. Therefore, in order to predict their occurrence...
Muscle proteins of the European anchovy Engraulis encrasicolus L. were analyzed using starch gel electrophoresis and isoelectric focusing on thin polyacrylamide ampholine gel. Twenty-two protein loci were analyzed and polymorphism was found in six of them. Based on genetic-biochemical data, we hypothesize that there are two anchovy subspecies, European and African. The former inhabits the Atlan...
abstract this research attempts to investigate the role of the blocking systems in surface cyclogenesis over eastern mediterranean sea; but particular attention is focused on the flood of iran during march 2000 over western states of iran as: hamadan, ilam, lorestan, kermanshah, kurdestan, zanjan, ghazvin.the data used for this research includes upper level and mean sea level pressure charts ev...
The Eastern Mediterranean Transient (EMT) occurred in the Aegean Sea from 1988 to 1995 and is the most significant intermediate-to-deep Mediterranean overturning perturbation reported by instrumental records. The EMT was likely caused by accumulation of high salinity waters in the Levantine and enhanced heat loss in the Aegean Sea, coupled with surface water freshening in the Sicily Channel. It...
Aspects of hydrography and large-scale circulation observed in the Mediterranean Sea during the M84/3 and P414 cruises (April and June 2011, respectively) are presented. In contrast to most of the recent expeditions, which were limited to special areas of the basin, these two cruises, especially the M84/3, offered the opportunity of delineating a quasi-synoptic picture of the distribution of th...
The Turkish Strait System, which is the only connection between Black Sea and Mediterranean Sea, a challenging region for ocean circulation models due to topographic constraints water mass structure. We present newly developed high resolution unstructured finite element grid model simulate System using realistic atmospheric forcing lateral open boundary conditions. find that jet flowing from Bo...
Recently ( ) a new source of deep water formation in the Eastern Mediterranean was found in the southern part of the Aegean sea. Till then, the only source of deep water formation in the Eastern Mediterranean was in the Adriatic sea; the rate of the deep water formation of the new Aegean source is , three times larger than the Adriatic source. We develop a simple 3 box-model to study the stabil...
The overarching goal is to elucidate the complex dynamics of outflows connecting basins through straits. The long term scientific goals are to (a) understand the physical mechanisms that control the exchange between two marginal seas with substantially different water mass characteristics (Aegean Sea and Black Sea) through a complex system of straits (Turkish Straits System); (b) quantify the p...
The lucrative and highly migratory Atlantic bluefin tuna, Thunnus thynnus (Linnaeus 1758; Scombridae), used to be distributed widely throughout the north Atlantic Ocean, Mediterranean Sea and Black Sea. Its migrations have supported sustainable fisheries and impacted local cultures since antiquity, but its biogeographic range has contracted since the 1950s. Most recently, the species disappeare...
Precipitation is one of the important aspects of the Earth’s climate that has both spatial and temporal variations. Understanding the behavior of this element and analyzing its spatial and temporal variation is importantwhich can lead to a comprehensive and detailed planning for water resource management and agriculture. Geostatistical techniques and spatial autocorrelation analysis are t...
