Effects of large-scale deforestation on precipitation in the monsoon regions: remote versus local effects.
In this paper, using idealized climate model simulations, we investigate the biogeophysical effects of large-scale deforestation on monsoon regions. We find that the remote forcing from large-scale deforestation in the northern middle and high latitudes shifts the Intertropical Convergence Zone southward. This results in a significant decrease in precipitation in the Northern Hemisphere monsoon...
متن کاملA high-resolution history of the South American Monsoon from Last Glacial Maximum to the Holocene
The exact extent, by which the hydrologic cycle in the Neotropics was affected by external forcing during the last deglaciation, remains poorly understood. Here we present a new paleo-rainfall reconstruction based on high-resolution speleothem δ18O records from the core region of the South American Monsoon System (SAMS), documenting the changing hydrological conditions over tropical South Ameri...
متن کاملStable isotopes in precipitation recording South American summer monsoon and ENSO variability: observations and model results
The South American Summer Monsoon (SASM) is a prominent feature of summertime climate over South America and has been identified in a number of paleoclimatic records from across the continent, including records based on stable isotopes. The relationship between the stable isotopic composition of precipitation and interannual variations in monsoon strength, however, has received little attention...
متن کاملThe Role of the Himalayas and the Tibetan Plateau within the Asian Monsoon System
JULY 2004 AMERICAN METEOROLOGICAL SOCIETY | T he key mission of the Coordinated Enhanced Observing Period (CEOP) is to understand water and energy cycles, document their physical processes, and simulate and predict water and energy fluxes. This involves a synergetic strategy integrating satellite data, in situ observations, assimilated data, and modeling simulations. A CEOP Monsoon Systems Work...
متن کامل9. the South American Monsoon System
The main characteristics of the South American monsoon system are reviewed. According to some diagnostics, the wet season in tropical South America begins in early October over the Brazilian highlands and spreads northward. Wet season rain rates are somewhat smaller than those in other continental monsoons. The annual cycle of precipitation is most pronounced in the southern Amazon, where some ...
