  • The effect of man's activities on climatic changes in Evolution des atmosphères planétaires et climatologie de la terre=Evolution of planetary atmospheres and climatology of the earth.
  • Although considerable uncertainties remain, state-of-the-art climatic theories suggest that major global climatic changes due to human activities are possible as soon as the end of this century.
  • L'évolution du climat normand depuis deux siècles in Evolution des atmosphères planétaires et climatologie de la terre=Evolution of planetary atmospheres and climatology of the earth.
  • (1763-1978) ; Climat historique ; France ; Géographie de l'Europe ; Normandie ; Variation climatique
  • In Normandy, France, accurate informations are pick up since 1780. Unfortunately, no complete and homogenous series exist. But, except few years, it is possible to reconstitute the evolution of temperature and rain. The variations of norman climate
  • are insignificant. No little ice age till 1850, no warning since this date. We have tried to explain the stability of climate in this province by an increase of oceanic tendancy. (The Author).
  • A seasonal climate model for Earth in Evolution des atmosphères planétaires et climatologie de la terre=Evolution of planetary atmospheres and climatology of the earth.
  • After monthly and zonally averaged climatic data fields are represented by Legendre polynomials in latitude and Fourier series in time, it is seen that only a few terms are necessary to describe the gross features of the seasonal oscillation
  • L'évolution du climat de la terre depuis trois millions d'années in Evolution des atmosphères planétaires et climatologie de la terre=Evolution of planetary atmospheres and climatology of the earth.
  • The main features of the climatic evolution of the Earth since the upper Pliocene are summarized. The deep water circulation and continental rainfall anomalies during a glacial period are emphatized.
  • Mechanisms of short-period climate fluctuations in Evolution des atmosphères planétaires et climatologie de la terre=Evolution of planetary atmospheres and climatology of the earth.
  • Short-period climate fluctuations arise from statistical sampling fluctuations of random weather and from physical forcing by external influences. The first mechanism produces a climate noise that obscures the potentially predictable signals arising
  • Les actions du climat et de l'Océan Atlantique sur le régime de la mer Méditerranée, notamment au cours des périodes glaciaires in Evolution des atmosphères planétaires et climatologie de la terre=Evolution of planetary atmospheres and climatology
  • The consideration of the heat and mechanical energy, water and salt budgets of the Mediterranean enables us to suggest a physical model of the transports of this sea, which is subject to the climate and to the Atlantic boundary conditions
  • . This model allows the investigation of the effects of the climate upon the hydrological parameters during the last ice age.
  • Evolution of the Indian climates and water use planning in Evolution des atmosphères planétaires et climatologie de la terre=Evolution of planetary atmospheres and climatology of the earth.
  • Climatic change since 1000 AD in Evolution des atmosphères planétaires et climatologie de la terre=Evolution of planetary atmospheres and climatology of the earth.
  • (1000-1978) ; Climat historique ; Géographie physique ; Petit Age Glaciaire ; Variation climatique
  • Rayonnement thermique et émissivité planétaires des latitudes, noeud du déterminisme énergétique de l'évolution des climats in Evolution des atmosphères planétaires et climatologie de la terre=Evolution of planetary atmospheres and climatology
  • (in cal/cmmin): N=T +0,096 n+N () with =0,750 (10,704n). The interest of this expression as a tool for the theoretical analysis of climates and paleoclimates is shown with several examples.
  • Some mecanisms of climatic changes induced by encounters of solar system with an interstellar cloud in Evolution des atmosphères planétaires et climatologie de la terre=Evolution of planetary atmospheres and climatology of the earth.
  • Evolution of the earth's climate during the Tertiary era in Evolution des atmosphères planétaires et climatologie de la terre=Evolution of planetary atmospheres and climatology of the earth.

  • For a millenium (933-1974 A.D.), large scale variations in the mean ring widths of the Larch (Larix decidua Mill.) in the southern Alps (Alpes-Maritimes, France, 2000 m altitude) have been corresponding nearly exactly to the great climatic epochs
  • The cause of Glacial to Interglacial climatic change in Evolution des atmosphères planétaires et climatologie de la terre=Evolution of planetary atmospheres and climatology of the earth.
  • temperature follow the general climatic fluctuations of the same time. The consequences of these climatic changes can be observed in the hydrological system of the Ligure sea.
  • Climatic changes in Antarctica during the last 30,000 years in Evolution des atmosphères planétaires et climatologie de la terre=Evolution of planetary atmospheres and climatology of the earth.
  • Crystal size and total gas content of ice: two indicators of the climatic evolution of polar ice sheets in Evolution des atmosphères planétaires et climatologie de la terre=Evolution of planetary atmospheres and climatology of the earth.
  • La mesure de la taille des cristaux sur les carottes de glace du dôme C (Antarctique) se révèle être un outil paléoclimatique. Les variations de ce paramètre liées au climat ne peuvent pas s'expliquer directement par des effets de température... La
