An interdisciplinary approach to the analysis of extreme events over the Mediterranean

Although extreme events have always been important in meteorological research, they are receiving special attention in the context of climate change. There are a number of extreme events (e.g. frost, wildfires, gusty winds, severe convection with its byproducts, etc.) which have in common that they can cause significant material damage/losses and human casualties. Therefore, their study is of great interest not only for the meteorological community, but also represents a great need for a comprehensive interdisciplinary approach. Through this lecture, more detailed knowledge will be given about several recently conducted interdisciplinary research with agronomists, foresters, chemists and biologists on several different topics. The first of them includes the impact of climate change on viticulture and winemaking, since it is one of the important economic branches of most Mediterranean countries. Many studies show that changes in temperature and precipitation (and often deep moist convection) have a great impact on viticulture, considering that plants are among the first to react to climate changes, e.g., changes in temperature and humidity. Recent studies have shown that the impact of climate change is often visible in the earlier beginning of the phenological phases of the vine, such as budbreak, flowering, veraison and harvest. An earlier onset of budbreak indicates a potentially significantly higher risk of early frosts. Another theme includes extreme wildfire analysis and fire weather research involving fire management and fire risk awareness in the Mediterranean. The possibility of wildfire modeling will be demonstrated, which enables research into the occurrence of pyroconvection, and the strong interaction between the atmosphere and fire evolution. The third topic includes the analysis of the transport of Saharan dust over long distances across the Mediterranean. Mineral dust, as one of the most widespread types of aerosols, is an extremely important factor in climate change assessments. It affects atmospheric radiation, cloud formation, and during deposition it transfers micronutrients to both land and ocean ecosystems. The Sahara desert is one of the main global sources of dust that, through atmospheric transport, has an impact on the Mediterranean. Deposition of mineral dust in the atmosphere plays an important role in supplying the sea with nutrients. In this interdisciplinary research, the frequency of these rare events is analyzed as well as their impact on the marine biosphere and biological activity
