THIS translation is an authoritative digest of much Russian work on moisture and moisture transport in the atmosphere. The emphasis is geographical rather than geophysical, climatological rather than meteorological, and largely devoted to the territory of the USSR The title would lead one to expect a discussion of the theory of evaporation, of the general circulation of atmospheric moisture, and of the dynamical mechanisms for condensation and precipitation, but these do not appear although some Russian contributions in these fields are outstanding. Attention is by contrast directed to such questions as the statistical relationship between precipitation and atmospheric humidity and the contribution made by local evaporation to local precipitation-questions which seem to be less relevant the more the geophysics is understood. The most valuable chapter is perhaps that on moisture flux in the atmosphere, which includes reference to important work in America and Britain. The chapter on macro-turbulent exchange is also notable as introducing important ideas due to Obukhov, Monin and Yudin. On the whole, the book has no great novelty, but one mUilt be grateful to the authors for making a survey with almost 300 references, and to the publishers for providing a tra. nslation which will find a permanent place in the literature even if its interest is mainly historical. With the International Hydrological Decade upon us, and many new workers and new countries entering the field, this survey monograph of Russian work is particularly opportune. RC SUTCLIFFE
