A package of computer programs for the analysis of satellite laser ranging data has been written at the Royal Greenwich Observatory. The methods used are described, and the Earth rotation parameters and station coordinates derived from the MERIT Lageos data are given, with comparisons with other determinations. The uncertainty of the absolute value of the z-coordinate of the stations is discussed, and a method of short-arc analysis for determining baselines is described.

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.

The Military

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.

The departure of the greater part of the Greek community from Egypt is one of the many sad stories of the post-war Mediterranean. This article focuses upon the reports of the Greek Consul-General in Alexandria, Byron Theodoropoulos, regarding the Egyptian ‘Socialist Laws’ of summer 1961, which gave the coup de grâce to the Greek community. It argues that the expulsion of the Greeks was part of a wider redistribution of power in the region. This episode, together with similar experiences in other parts of the Mediterranean, evidently cemented the determination of a younger generation of political leaders and diplomats to seek Greece's future in the cosmopolitan, post-nationalist West, rather than in a ‘Near East’ rife with nationalism and economic failure.
