No work has been completed related to changes in long-term extreme precipitation, temperature and sea level events in the Egyptian Mediterranean region. The present case study can be considered as an initial fair trial to get closer to the weather extremes over Alexandria region in Egypt.

The authors of the present study initially investigated these variations in the South-eastern Mediterranean Sea. Their results determined cyclic behaviour and expanded the focal point of interest from local to regional scale depending on the cyclic occurrence of the Nile drought and agreed with the detected 70-year cycle determined by other researchers.
Using the linear and quadratic regression approaches, the present work aims at modelling the general long-term trend in the monthly surface hydrographic anomalies (MSTA & MSSA), for 63 years (1948-2010), within the North Atlantic and Pacific Oceans. The paper also compares the present results with that obtained by the same techniques and period at the same latitudes in the South-eastern Mediterranean Sea.
The MSTA variations in the two oceans reflect general linear increases (opposite to that in South-eastern Mediterranean Sea) and two quadratic concave-up (cyclic) forms with different magnitudes. The years of minimum occurrence in the two oceans precede that in the South-eastern Mediterranean basin.
The linear trends of MSSA are in contrast. While the North Atlantic examined a general trend of increase (as in the South-eastern Mediterranean Sea), the North Pacific had a rate of decrease. The MSSA quadratic regression model of the former (as in the South-eastern Mediterranean basin) reflected a concave-up (cyclic) form, with same minimum occurrence in 1980, while the later did not show any cyclic trend.

Looking at the oceans as a vast sustainable clean energy resource to satisfy present high humankind energy demands has been strongly recommended. Several types of renewable energy resources exist in the oceans: waves, tides, thermohaline variations, currents & offshore winds. Choosing a suitable site to deploy tidal turbines is not a trivial process. Various constraints must be satisfied subject to basic criteria dependent upon local factors, technology limitation and economic consideration. This study justifies the nomination of the Strait of Messina as an exceptional tidal-current energy resource within the Mediterranean Sea basin. A detailed desk-based Environmental Impact Assessment study is performed using the interactive matrix approach. The University of Edinburgh “Tidal Flow Development (TFD)” numerical model is used to mimic the tidal environment of the Strait of Messina in different cases. Finally, a laboratory model is used to simulate the flow regime within the Strait of Messina using the Particle Image Velocimetry (PIV) technique.

The study used hourly sea level data extended over 10 years from January 2002 to December 2011. A comprehensive descriptive statistical analysis of sea level monthly variations was introduced. The T_Tide package was used to obtain the astronomical constituents, which are in turn used to calculate the form factor to specify the tidal cycle in the Harbor, and to obtain the main water level characteristics. The meteorological factor was calculated by subtracting the tidal elevation from the recorded sea level. The impact of the meteorological factors on the observed sea level fluctuations was more obvious in winter than in summer. The effect of the meteorological conditions on the observed possible largest sea level range was $${~}^{1}\!\left/ \!{~}_{3}\right.$$ 1 3 that of the tidal impact. No extr...

The latest issue of the IPCC report (AR6) on the Mediterranean Sea region released in 2022 has assessed that the Mediterranean Sea exhibits robust accelerating SLR rates at different magnitudes in different locations, which will impact the life of one-third of the Mediterranean population, i.e. ~ 150 million ARTICLE INFO
