Strong Winds Observed Trends, Future Projections
Strong winds Observed trends, future projections Philippe DROBINSKI UMR LMD, France Pinhas ALPERT Tel-Aviv University, Israel Leone CAVICCHIA CMCC, Italy Emmanouil FLAOUNAS National Observatory of Athens, Greece Assaf HOCHMAN Tel-Aviv University, Israel Vassilki KOTRONI National Observatory of Athens, Greece Introduction The Mediterranean Sea is an almost enclosed basin surrounded by mountain chains with a complex coastal orography and numerous islands, many of which mountainous. The complexity of the physiographic characteristics deeply influences the atmospheric circulation at local scale, giving rise to strong regional wind regimes (see fig. 1) (HMSO, 1962). In the Alboran Sea (the westernmost Mediterranean), the levanter blows from the east and in winter it can be strong and long lasting (up to 10 days). In the western Mediterranean, the north-north- west cold dry mistral and its companion wind the tramontane blow in the Gulf of Lion, occasionally up to the African coasts. The northeasterly strong cold bora affects the entire Adriatic Sea and bora-type winds also occur in the northern Aegean Sea. In this region, storm surges are produced by a regional wind, the 115 The Mediterranean Region under Climate Change westerly southwesterly libeccio, mainly during winter, and the warm and wet southeasterly sirocco is produced mainly in the fall. In the Levantine basin, the prevailing winds are the etesians, strong dry north winds like those that prevail in the Black Sea. The wind speeds associated with these regional wind regimes often reach surface values > 15 m s-1 (with gusts of over 20-25 m s-1). The Mediterranean basin is also one of the main regions of cyclogenesis in the world and the strongest windstorms are often associated with a cyclone (Lionello et al. -

Recent Large Scale Environmental Changes in the Mediterranean Sea and Their Potential Impacts on Posidonia Oceanica
Article Recent Large Scale Environmental Changes in the Mediterranean Sea and Their Potential Impacts on Posidonia Oceanica Malgorzata Stramska 1,* and Paulina Aniskiewicz 1,2 1 Institute of Oceanology, Polish Academy of Sciences, 81-712 Sopot, Poland 2 Centre for Polar Studies, Faculty of Earth Sciences, University of Silesia, 41-200 Sosnowiec, Poland; [email protected] * Correspondence: [email protected] or [email protected]; Tel.: +48-5873-11600 Received: 19 November 2018; Accepted: 14 December 2018; Published: 9 January 2019 Abstract: Climate related changes can have significant effects on Posidonia oceanica, an endemic seagrass species of the Mediterranean Sea (MEDIT). This seagrass is very important for many aspects of functioning of the sea but there is an increasing number of reports about the ongoing loss of its biomass and area coverage. We analysed multiyear data of the sea surface temperature (SST), sea level anomalies, ocean colour MODIS-A and ERA-Interim reanalysis. The results provide a description of current environmental conditions in the MEDIT and their spatial and temporal variability, including long-term trends. We defined regions where the extent of the P. oceanica meadows may be limited by specific environmental conditions. Light limitation is more severe near the northern and western coasts of the MEDIT, where the vertical diffuse attenuation coefficient is large. In the zone extending from the Gulf of Lion towards the south, significant wave heights reach large values. Wave action may destroy the plants and as a result the shallow water depth limit of P. oceanica meadows is most likely deeper here than in other regions. -
Macedonian Succession: a Game of Diadems
Macedonian Succession: A Game of Diadems David K Coblentz A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy University of Washington 2019 Reading Committee: Carol Thomas, Chair Michael Williams Mary O’Neil Program Authorized to Offer Degree: History © Copyright 2019 David K Coblentz University of Washington Abstract Macedonian Succession: A Game of Diadems David K Coblentz Chair of the Supervisory Committee: Carol Thomas Department of History In this dissertation, I explore royal succession in Macedonia from the early Argead period until the fall of Macedonia to the Romans in 168 BCE. Particular attention is paid to the transition from the unstable, violent pattern of succession that dominated during and immediately after the Argead period to the peaceful pattern of succession that emerged in Antigonid Macedonia. The experience of the early Antigonid basileis is contrasted with that of the dynasties established by other Diadochi after the death of Alexander the Great. I suggest that game theory can provide a useful tool for understanding why violent succession patterns dominated in most Macedonian dynasties and also why a more peaceful pattern of power transfer was able to exist in the Antigonid dynasty. Ultimately, I use the surviving textual evidence from the early successor period to hypothesize a scenario that may have led to Antigonid dynastic stability. I also revisit and challenge several common modern hypotheses pertaining to Macedonian succession, including claims that Heracles, son of Barsine, was illegitimate and also that most of the Iranian brides married at Susa by prominent Macedonians were set aside by their husbands after Alexander’s death. -
Chapter 2: the Mediterranean Environment
Chapter 2: The Mediterranean environment 2 The Mediterranean environment 2.1 Introduction Qualitatively, the Mediterranean climate is typified by long warm and dry, often hot and sunny summers, with occasional showers and thunderstorms (Wallen, 1970). The winter months are cool and variable with periods of dry and cloudy days interspersed by sunny periods or rain. Characteristic of this regime are intense rainy seasons that occur in spring or autumn dependent on location. Gales occur in winter, in some places quite frequently, and along coastal areas and the Spanish valleys fog may occasionally appear (Rudloff, 1981). A more quantitative definition, and an example of ‘climate classification’ is given in Table 2.1, based on the work of Köppen (1931). Köppen’s work, a classification of all world climates based upon temperature and precipitation and delimited by spatial variations in flora, was the first to formally introduce the idea of a strictly ‘Mediterranean climate’ (‘Cs’, see Table 2.1), consistent with the above qualitative description. It is an example of one of five types (A-E, tropical to polar) of climate principally defined by temperature, and further subdivided according to precipitation and seasonality. The flora that delimits the Mediterranean type is generally hardy, able to cope with low levels of moisture and to make good use of the high levels of sunlight available. Woody scrub, olive groves, citrus plantations and small regions of deciduous forest are all apparent, illustrating the range of landuse found within the basin
