Trieste is located at the extreme end of the northern coast of the Adriatic, where the arm of the sea reaches most deeply into the European continent. By its position Trieste is thus a part of Central Europe no less than of the Mediterranean area — if we take into account the fact that the distance between Vienna and Trieste is less than that between Trieste and Rome. On the other hand, Trieste is in an area where the Apennine peninsula meets the Balkan, where for millenia two cultural spheres have been juxtaposed: the Eastern — Greek, Byzantine and Slavic — and the Western — Latin, Romance and German. The complexity of the geographical and cultural circumstances is further increased by the national heterogeneousness of the inhabitants, Italians and Slovenes. Italians predominate in the town, Slovenes in the countryside.

Abstract. A simulation of the last millennium is compared to a recent spatio-temporal reconstruction of summer temperature over Europe. The focus is on the response to solar forcing over the pre-industrial era. Although the correlation between solar forcing and the reconstruction remains small, the spatial regression over solar forcing shows statistically significant regions. The meridional pattern of this regression is found to be similar in the model and in the reconstruction. This pattern exhibits a large warming over Northern and Mediterranean Europe and a lesser amplitude response over Central Europe. The mechanisms explaining this pattern in the simulation are mainly related to evapotranspiration fluxes. It is shown that the evapotranspiration is larger in summer over Central Europe when solar forcing increases, while it decreases over the Mediterranean area. The explanation for the evapotranspiration increase over Central Europe is found in the increase of winter precipitation there, leading to a soil moisture increase in spring. As a consequence, the evapotranspiration is larger in summer, which leads to an increase in cloud cover over this region, reducing the surface shortwave flux there and leading to less warming. Over the Mediterranean area, the surface shortwave flux increases with solar forcing, the soil becomes dryer and the evapotranspiration is reduced in summer leading to a larger increase in temperature. This effect appears to be overestimated in the model as compared to the reconstruction. Finally, the warming of Northern Europe is related to the albedo feedback due to sea-ice cover retreat with increasing solar forcing. These results show that the last millennium can be useful to evaluate the sensitivity of climate models to radiative forcing changes, using spatio-temporal reconstruction of climate.

AbstractAedes pulcritarsis is a tree-hole breeding species with its main distribution in the Mediterranean area. Within the scope of two independent monitoring programmes, this mosquito species was detected for the first time in Austria, in the province of Lower Austria (2018, districts Mistelbach and Gaenserndorf; 2020, district Bruck an der Leitha). As the climatic and habitat situation in Central Europe seems to be generally suitable for this species, the most likely explanation for the species not being recorded previously is that it might have been overlooked in the past due to its specialized breeding habitat. However, further research on the distribution of Ae. pulcritarsis in Austria would be needed to support this hypothesis. The results from this study will contribute to the investigation of the northern distribution limit of Ae. pulcritarsis in Europe and possible changes thereof.

Evidence is given of the distribution of pre-warm front rainfall at the meso-γ scale, together with a discussion of the main mechanisms producing this variability. An inland region in the Mediterranean area is considered. The selected rainfall type is commonly considered the most regular inasmuch as it is usually unaffected by extended convective motions. Despite this, within a storm a large variability in space was observed. For 90% of measurements, the typical deviations from the area-average total depth ranged from - 40 to 60 % and the storm ensemble-average rainfall rate over an hilly zone was 60 % greater than that in a contiguous low-land zone generally placed upwind. This variability is largely explained in terms of forced uplift of air mass over an envelope type orography. For a few storms smaller orographic effects were found in locations influenced by an orography with higher slopes and elevations. This feature is ascribed to the compact structure of these mountains which probably determines a deflection of air mass in the boundary layer. The importance of this type of analysis in the hydrological practice is also emphasized.

This chapter deals with ancient warfare and the environment. Hunting was often been considered as a form of warfare, and art frequently portrayed humans in battle with animals. Armed conflict had its direct influences on the environment. Along with damage to settled agriculture, warfare had affected other lands such as pastures, brush lands, and forests. It is noted that birds, pigs, bears, rodents, snakes, bees, wasps, scorpions, beetles, assassin bugs, and jellyfish have been employed as weaponized animals in ancient warfare, which, in the Mediterranean area and Near East, had vital environmental properties. The direct effects of battle have been shown by ancient historians, but just as important were the influences of the military-oriented organization of societies on the natural environment and resources.
