             abstract = "Two Amazonian deforestation simulation experimenta have been 
                         performed with the French spectral GCM EMERAUDE coupled wlth the 
                         ISBA land surface parameterisations of Noilhan and Planton (1989). 
                         The deep convection scheme ot Bouqeault (1985) was used in the 
                         first experiment while the Ruo scheme (1965, 1974), includinq the 
                         modifications of Geleyn (1985), was used in the second one. For 
                         each experiment the model was inteqrated with the original soil 
                         and veqetation types from the classification of Wilson and 
                         Henderson-Sellers (1985) in the contraI case (ctrl). In the 
                         deforested case (def) a hypothetical qrass land cover replaced the 
                         rainforest over a larqe surface over the Amazonian reqion. The 
                         main ISBA parameters for forest and qrass land are respectively: 
                         albedo 12.5t and 19ti rouqhness lenqth 2 m and 6 cmi active soil 
                         column depth 4 m and 2 mi and minimum surface resistance 42 sim 
                         and 75 sim. The initial soil water content used are that from 
                         Mintz and Seratini (1989) climatoloqy for a mid-Cecember 
                         situation. The precipitation pattern obtained with the Kuo scheme 
                         seems in better aqreement with the climatoloqy over the South 
                         America continent than that obtained with the Bouqeault one. Over 
                         the deforested reqion the precipitation decreases, followinq the 
                         decreased evapotranspiration, when the Kuo scheme is used while 
                         the humidity converqence, of about 50t of precipitation, remains 
                         unchanqed. An increase of precipitation resulta from the 
                         deforestation when the Bouqeault scheme is used as a consequence 
                         of the increased humidity converqence. The impact ot the increased 
                         albedo is compensated by a decreased cloudiness in both 
                         simulations. The resulted averaqed surface temperatura remains 
                         almost unchanqed, althouqh the daily temperature amplitude is 
                         larqer in the def experimento This increased daily temperatura 
                         amplitude may be explained by the decreased rouqhness lenqth. An 
                         increased runoff resulta from the lower soil water capacity.",
