Uniform Title:
La Dynamiqie du temps et du climat
Content:
This is an up-to-date textbook on meteorology ond climatology with a fresh, unconventional view of the workings of the climate system, in which the author poses serious questions about the validity of certain aspects of current global warming theory.
The book is divided into three parts. In Part I the author discusses general circulation in the troposphere. He argues that such circulation is driven by thermal deficil at the poles, causing Moving Polar Highs (MPHsl, which have the principal role of feeding cold air towards the tropics, This in turn causes warm air to move up towards the poles. The relief and distribution of land masses, and the Earth's rotation, control the trajectories of the MPHs, and the formation of Anticyclonic Agglutinations (AAs). The latter determine the properties of tropical circulation, the trade winds, and tropical monsoons.
These discussions lead, in Part II, 10 a consideration of the dynamics of the weather through the study of perturbations, including precipitation, the role of MPHs in polar and temperate regions and at tropical margins, pulsations in the trade winds and monsoons, the concept of the meteorologIcal Equator, and tropical cyclones.
Part Ill reviews the causes of climatic variations, including solar activity, variations relating to the Earth's orbit and axial inclination, volcanic eruptions and the anthropogenic greenhouse effect. The book concludes with a discussion of Palaeoclimatic variations and recent climatic evolution, including the Sahelian drought, changes in polar and alpine glaciers, and the El Niño/Southern Oscillation,
