Global Precipitations and Climate Change

Produktbeschreibung

In regard to global change, emphasis is generally placed on the increase in global temperature, but large changes in the distribution of precipitation are also likely to occur. Such changes have been redorded in the past by paleoclimatological studies or in the field of climatology. Different approaches to monitoring and forecasting the evolution of climate-scale precipitation are reviewed by paleoclimatologists, hydrologists, satellite meteorologists, and climate modellers.
