GEWEX Phase II Objectives (2003-2012)

• Produce consistent research quality data sets
  complete with error descriptions of the Earth's
  energy budget and water cycle and their
  variability and trends on inter-annual to decadal
  time scales, and for use in climate system
  analysis and model development and validation
• 2) Enhance the understanding of how energy and
  water cycle processes
• function and quantify their contribution to
  climate feedbacks
• 3) Determine the geographical and seasonal
  characteristics of the predictability
• of key water and energy cycle variables over
  land areas and through collaborations with the
  wider WCRP community determine the predictability
  of energy and water cycles on a global basis.
• 4) Develop better seasonal predictions of water
  and energy cycle variability
• through improved parameterisations
  encapsulating hydro-meteorological
• processes and feedbacks for atmospheric
  circulation models
• 5) Undertake joint activities with operational
  hydro-meteorological services and
• hydrological research programmes to
  demonstrate the value of new GEWEX
• prediction capabilities, data sets and tools
  for assessing the consequences
• of climate predictions and global change.

• CARRIES OUT RESEARCH ON OBSERVATIONAL SYSTEM AND
  DATA ANALYSIS TO REDUCE THE ERRORS IN THESE
  GLOBAL DATA AND DATA SETS.
• CARRIES OUT CLIMATE STUDIES WITH LONG TERM DATA
  SETS.

AMMA HAS BEEN ADOPTED AS A GEWEX CSE (JAN 2005).
ITS AIMS ARE

• To improve our understanding of the West African
  Monsoon and its physical, chemical and biological
  environment.
• To provide the underpinning science that relates
  climate variability to issues of health, water
  resources and food security and defining the
  relevant monitoring strategies.
• To ensure that the multidisciplinary research is
  efficiently integrated with prediction and
  decision making activities.

An Element of WCRP initiated by GEWEX

• Part-I(2005-2006)
• Apply CEOP Phase I datasets to accomplish the
  CEOP Phase I Research and Analysis Goals
  associated with Water and Energy Simulation and
  Prediction (WESP) and the CEOP Inter-Monsoon
  Model Study (CIMS) that were articulated in the
  CEOP Phase I Implementation Plan
• Build an expanded framework for a Water Cycle
  Observation and Data System based on the results
  of CEOP Phase I that can meet the needs of the
  IGOS-P Water Theme, COPES and targets set in the
  GEOSS Water Cycle Observation and Data System
  component of the GEOSS 10-Year Implementation Plan

15
An Element of WCRP initiated by GEWEX

• Part-II(2007-2010)
• Implementation of the CEOP-II Integrated
  Observation and Data System for the Global Energy
  and Water Cycle as planned in Part-I above
• Submit CIMS Results as a Contribution to WCRP Pan
  Monsoon Study
• Apply WESP results to an Extension of
  Down-scaling and transferability Studies and,
  thereby, as a contribution to the Integrated
  Water Resources Management (IWRM) process which
  is designed to assist countries in their
  endeavor to deal with water issues in a
  cost-effective and sustainable way.
• Undertake and conclude a Cold Region Study in
  Cooperation with the WCRP Climate and Cryosphere
  (CliC) Project and the International Polar Year
  (IPY) effort
• Undertake and advance scientific goals related to
  understanding and defining Extreme Event
  Mechanisms
• Undertake and advance knowledge of the
  interactions between Aerosols and the Water Cycle.

NEW DIRECTIONS WCRP-COPES Coordinated
Observation Prediction of the Earth System

• AIM To facilitate analysis prediction of Earth
  system variability change for use in an
  increasing range of practical applications of
  direct relevance, benefit value to society

• Some proposals under consideration
• Determine the predictive power of climate
  prediction systems
• Further develop techniques for ensemble
  prediction
• Determine the basis for projections of regional
  climate change
• Contributions to ESSP projects (e.g. GWSP)
• .. decadal prediction

GEWEX is in the process in defining its
contributions to WCRP-COPES
17
Implications

• Re-statement of WCRP Goal
• To facilitate analysis and prediction of Earth
  system variability and change for use in an
  increasing range of practical applications of
  direct relevance, benefit and value to society.
• Active role and responsibility for JSC JSC
  responsible for COPES
• Strengthened role and responsibility of Projects,
  Working Groups and Panels to achieve WCRP goals
• Commitment to evolving structure
• New Panels and Board (taskforces, workshops)
