<p>El Nino Southern Oscillation (ENSO) is a phenomenon in the equatorial Pacific that could have profound effects on climate around the world. Although ENSO impacts are fairly well-defined for south and north America, Australia and south-eastern Asia, they are not very clear for Euro-Mediterranean region. Some studies indicate that the negative phase of ENSO in Nino3 and Nino3.4 indices have similar effects in the negative phase of North Atlantic Oscillation (NAO).  ENSO impacts and teleconnection patterns are mostly studied using the Nino3.4 index. However, some recent studies indicate that the Nino1+2 index has higher correlation with climate variability over the Euro-Mediterranean region.</p><p>In this study, we investigate impacts of ENSO over the Euro-Mediterranean climate variability and atmospheric dynamics using the Nino1+2 and Nino3.4 indices. Additionally, we also tried to understand if there is any relation between ENSO and the Mediterranean and East Asian troughs. NCEP/NCAR Reanalysis surface air temperature, precipitation and 500 hPa geopotential height datasets and SST-based ENSO indices from ERSSTv4 were used in the analysis for boreal winter (December-January-February) for a period of 1950 - 2019. We utilized the Pearson correlation analysis to reveal the relation between these indices and climate parameters and the composite analysis  to define the pattern differences between the cold and warm phases of the indices.</p><p>Our preliminary findings show that there is a distinct correlation pattern between Nino indices and surface air temperature over the region of interest. Nino1+2 index has a more distinct dipole pattern with a significant positive correlation pole over central Europe and negative pole over north-eastern Africa. However, Nino3.4 indicates a rather zonal correlation dipole pattern whose poles are over northwest Africa (strongly positive) and northeast Africa (negative). It is also found that the Mediterranean trough location is sensitive to the phase of ENSO for both indices. Namely, the Mediterranean trough tends to be in the west of its climatological location for La Nina phases of Nino1+2 and Nino3.4, which affects the distribution of surface temperature and precipitation over the Euro-Mediterranean and Middle East and Northern Africa (MENA) regions. We concluded that the La Nina phase of Nino1+2 seems to play a more distinctive role in the dipole pattern. The surface air temperature is colder over the entire Europe while it is opposite in the Middle East region including Turkey. This dipole pattern is also detected for the La Nina phase of Nino3.4, but it is mostly observed over southwestern Europe and northern Africa. Comparison between the La Nina and El Nino phases of the Nino1+2 index indicates that for the La Nina phase precipitation is larger over the Aegean Sea and Italy and smaller in northern Europe.</p>

AbstractPerfumes have been known as utilizable but exclusive products since antiquity. Use of aromatic substances was first mentioned in archaic sources of the ancient world. The origin of such fragrant substances was mainly vegetable and animal. Throughout history, the use of subtle perfumes increased and some of the exotic materials became expensive and valuable commodities. They were the source of wealth for cultures and rulers. The contribution of the Arabs to the distribution of new crops, knowledge, industrial techniques and substances is a well-known phenomenon. In our article we intend to focus on the new perfumes that were distributed throughout the world thanks to the Arab conquests and the knowledge of their other uses, mainly medicinal, that was handed down along with the products themselves. About 20 common perfumes are known to have been used in the medieval world, though half of them were not mentioned in earlier sources.These phenomena will be dealt with and presented in a profile we built up for four perfumes: agarwood, camphor, musk and ambergris. The theoretical and practical uses of these perfumes that are presented in detail (based on various sources including traders’ documents, medical literature and practical Genizah fragments, dealing mainly with medicine) will serve as case studies for the understanding of new trends in the uses of perfumes after the Muslim conquest. Arab perfumes can be divided into three groups, according to their level of importance:A. New perfumes, mainly from the vast region named “India”; most of which (such as camphor, ambergris and sandalwood and a compound made out of them known as nadd and ghāliya) were not known in the Middle East and the Mediterranean region until the Muslim conquests.B. Perfumes that kept their popularity including: a variety of cinnamon, costus, spikenard, frankincense, saffron and rose.C. Perfumes that lost their worth like balsam and myrrh.It seems that camphor was the best and most cherished perfume that substituted balsam. Like balsam, the importance of myrrh that was imported from Arabia and East Africa also declined and it seems that its substitute was musk. Transformations in perfume fashion were in fact only part of a wider revolution of the Arabic material culture which the Middle East, the Mediterranean region and even many European countries experienced due to the Arab conquests.
