“…EMR countries may confront increased ozone levels as urbanization, rapid population growth, and increased utilization of fossil fuels leads to the production of ozone precursors (Chaudhary and Husain, 2006). The few studies from the region observed connections between weather patterns and ozone levels: higher ozone concentrations were linked to hotter months of the year in both Egypt (Nofal and Issa, 1990;Güsten et al, 1994) and Lebanon (Saliba et al, 2006).…”

Anthropologically induced climate change, caused by an increased concentration of greenhouse gases in the atmosphere, is an emerging threat to human health. Consequences of climate change may affect the prevalence of various diseases and environmental and social maladies that affect population health. In this article, we reviewed the literature on climate change and health in the Eastern Mediterranean Region. This region already faces numerous humanitarian crises, from conflicts to natural hazards and a high burden of disease. Climate change is likely to aggravate these emergencies, necessitating a strengthening of health systems and capacities in the region. However, the existing literature on climate change from the region is sparse and informational gaps stand in the way of regional preparedness and adaptation. Further research is needed to assess climatic changes and related health impacts in the Eastern Mediterranean Region. Such knowledge will allow countries to identify preparedness vulnerabilities, evaluate capacity to adapt to climate change, and develop adaptation strategies to allay the health impacts of climate change.

“…Ozone exceedances, the irregularity of which might be attributed to their secondary pollutant nature (Chelani 2014), usually occur under high pressure conditions, low or no movement of air masses, high temperature and high solar radiation (NRC 1991). Solar radiation and high temperatures are closely related to episodes of high ozone concentrations in the Mediterranean Basin (Fernández-Fernández et al 2011;Güsten et al 1994;Kouvarakis et al 2000;Ribas and Peñuelas 2004). In addition, during anticyclonic synoptic conditions, downward movements of ozone-rich air masses are expected (Kalabokas et al 2013;Sánchez et al 2008;Schürmann et al 2009).…”

The joint partition function approach to multifractal analysis (Meneveau et al., Phys Rev A 41:894-913, 1990) has been widely employed in order to characterize scale relationships between two variables coexisting along a single geometric support. The main contribution of this study was conducting a multifractal analysis for three variables coexisting in the same geometric support, in order to describe the influence across temporal scales of a meteorological and chemistry variable (temperature and NO 2 ) on tropospheric ozone concentrations. Hourly time series were recorded in the city of Seville (Spain) for summer 2011. Joint multifractal analysis was conducted by considering both the strange attractor formalism and the method of moments. Results confirmed the scale dependence among the studied variables and demonstrated the capability of joint multifractal analysis to completely characterize the scaling behaviour among three variables. Temporal variability in temperature is strongly reflected on ozone concentrations across analyzed temporal scales, but the joint multifractal spectrum for nitrogen dioxide and ozone suggest a lower degree of correlation. A loss of multifractality is found when both high temperatures and nitrogen dioxide concentrations occur. By contrast, greater variability is found in the opposite scenario.

“…Surface ozone levels were also examined in Cairo. Gusten et al (1994) studied the ozone formation in the Greater Cairo in 1990. The peak values of 120 ppb and daily mean value of 50 ppb throughout the year indicate a substantial contribution of photochemistry to the ozone content of the atmosphere.…”
