Progress on Understanding Land-Atmosphere Interactions and Surface Hydrology during the North American Monsoon Avances en el conocimiento de las interacciones tierra-atmósfera y la hidrología en superfcie durante el Monzón de Norteamérica

摘要

Land surface processes have been considered to play animportant, yet poorly understood, role on the evolutionof the North American Monsoon System (NAMS). Insummarizing the results of the NAME Process Study,Higgins and Gochis (2007) indicated that surface flux,vegetation and soil moisture measurements taken duringNAME could potentially help constrain estimates ofland-atmosphere interactions and moisture recycling.To understand these land surface-atmosphere feedbacksinvolves observations and modeling of the land phase ofthe hydrological cycle. As indicated by Vera et al. (2006),only the major hydrologic features of the NAMS, suchas the seasonal march of precipitation and stream?ow atcoarse spatial scales, have been quantifed. Motivated bythese studies, several efforts by a team of U.S. and Mexicoscientists were carried out during 2006-2009 in the NAMSregion.
