“…(hi) Sinkiang, particularly the Tarim basin in central Asia near 36-42° N, 80-90° E, was crossed by the ancient Silk Route which was used by trading caravans between China and the west in Roman times, when there was a chain of cities and settlements there and remnants of forest. Today it is largely a sandy desert (Wadia i960;Chappell 1970Chappell , 1971.…”

After reviewing the basic conditions which govern climate and the distribution of climates over the globe, with particular attention to the large-scale circulation of the atmosphere and the variations which it undergoes, this contribution proceeds to consider the sites of the early centres of civilization (particularly those that flourished between about 3000 and 1000 b.c.) and routes of travel by land and sea, some of which stand in a surprising relationship to the natural environment as it exists today. The sequences of variations of prevailing temperature, of sea level, of forest limits and rainfall, cloudiness, etc., and of the levels of great inland waters are reconstructed and lead to a consistent picture of the broad sequence of climatic regimes: for those regimes which differed most from the present-day northern hemisphere maps can be given. Climatic fluctuations on time scales from a decade or two to a few centuries are then considered: fluctuations tending to repeat at 200 or 400-year intervals seem rather prominent.

The influence of some climatic oscillations and sunspot number on river flows in Romania, Ukraine, and Moldova is verified by using standard wavelet analyses. The selected climate oscillations are Arctic Oscillation (AO), Antarctic Oscillation (AAO), East Atlantic Oscillation (EAO), East Atlantic/West Russia Oscillation (EAWRO), NINO3.4, North Atlantic Oscillation (NAO), Pacific/North America Oscillation (PNAO), Pacific Decadal Oscillation (PDO), Polar/Eurasia Oscillation (PEO), Scandinavian Oscillation (ScandO), Southern Oscillation (SO), and West Pacific Oscillation (WPO). Forty-five hydrological stations from an area of 45,000 km(2) were used in order to discover the spatial evolution of the periodicities found in rivers. The wavelet analysis is novel for the rivers in the study area. There is an important difference between the periodicities found in mountain and plateau areas and those found in the plain area. There is a general downstream increase in the confidence level of the identified periods, even if the atmospheric precipitation has more relevant periodicities in the mountain area. The periodicities can be grouped into two compact groups: 1-16.5 and 27.8-55.6 years. The correlation matrix of the global wavelet spectrum (GWS) values indicates that NAO, EAWRO, PDO, and the sunspot number are the main factors that generate the periodicities in rivers. It is the first time when the influence of PDO on local rivers is proven. All river periodicities smaller than 16 years have a confidence level of 0.95 or above, as proven by the GWS analysis of the daily discharge data, and are caused by multiple external factors.
