  1. NOAA Pan American Climate Studies Objective: To extend the scope and improve the skill of operational seasonal-to-interannual climate prediction over the Americas tao.atmos.washington.edu/pacs

  2. Objectives: better understanding and more realistic simulation of: • boundary forcing of seasonal-to-interannual climate variations over the Americas • the evolution of tropical sea surface temperature anomalies • the seasonally varying mean climate over the Americas and adjacent ocean regions, • the structure of the ITCZ/cold tongue complex • the relevant land surface processes.

  5. CLIVAR/VAMOS • Variability of the American Monsoon Systems • International science coordination mechanism • Focus on the monsoon systems in order to capitalise on major heat sources that shape the global atmospheric circulation.

  6. VAMOS Major objectives • to describe, understand, and model the mean and seasonal aspects of the American monsoon systems, • to investigate their predictability and to make predictions to a feasible extent, • to prepare products in view of meeting societal needs

  7. VAMOS Focus • rainfall and the probability of occurrence of significant weather events such as tropical storms and temperature extremes • includes associated perturbations in the planetary, synoptic and mesoscale flow patterns including those in the winter hemisphere. • region of interest covers both the tropical and the extratropical Americas and surrounding oceans.

  8. VAMOS Science Panel • Roberto Mechoso (chair) UCLA, USA; Victor Magaña (vice-chair), UNAM, Mexico • Tony Busalacchi, NASA, USA; Steve Esbensen, Oregon State Univ, USA • H. Fuenzalida, Univ. de Chile, Santiago • Vern Kousky, NOAA/CPC, USA • Antonio Moura, IRI, USA; Joel Picaut, NASA, USA • Jim Shuttleworth,UnivArizona, USA • Pedro da Silva Dias, USP, Brazil • Carolina Vera, CIMA, UBA, Argentina • Mike Wallace, Univ. of Washington, USA

  9. VAMOS Working groups • Process Studies (Bob Weller) • Data (Victor Magaña) • Sustained Measurements (Vern Kousky) • Stratus Working Group (Bruce Albrecht) • South American Monsoon (Pedro Silva Dias and Julia Paegle, co-chairs)

  10. Workshop on VAMOS and PACS Field Programmes • São Paulo, BR on March 30-April 2, 1998 • Develop plans field work to be done as part of VAMOS • Co-ordinate monsoon research programmes by the nations in the Americas • 60 participants from 10 countries. • For report and programs descriptions see www.clivar.ucar.edu/vamos_rep_toc.html
