Onlythe interior regions,shut oft from oceanicmfluences by very highmountains, have littleor no rain in summer,and are in consequencedeserts. Climatic Areas.—Asia mav be divided into five great climatic ^^^- ^30-y/>- tsotlter,u. fo> As:a. (After Buchan.) areas—(i) The Arctic Cold Dry Area, with a mean temperature not exceeding50° F, in the warmest summer month, and a mean rainfall never over i inchin thj wettest month. This is a small region ahnost entirelv within the Arctic. Asia 431 circle. (2) The Siberian or Temperate Coniinenial Area has great severity ofwinter cold, but the summer temperatures range from 50° to 70° or 75° F. Thetemperature extremes are greater in* the east than in the west. Hardly anyrain falls here in winter, but in the short summer a mean monthly fall offrom 1 to 2 inches is observed. (3) The Central or Arid Area, includingArabia, Iran, Turan, Taklamakan and Gobi, is one of varied elevationand of varied temperature conditions. Most of it is very dry, but slightwinter rains characterise the -v^est, whereas what precipitation occurs inthe east falls mainly in summer. The extreme south of Arabia is alsoa region of summer rains. This area exhibits in a high degree thedesiccation characteristic of the central plateaux of great mountain arid basin of Taklamakan, for example, abounds in ruined cities ot atime when rain must have been abundant, land fertile, and population dense.(4) The Monsoon A
