Prediction of climate relies on models, and better model prediction depends on good model physics. Improving model physics
requires the maximal utilization of climate data of the past, present and future. CEOP provides the first example of a
comprehensive, integrated global and regional data set, consisting of globally gridded data, reference site in-situ
observations, model location time series (MOLTS), and integrated satellite data for a two-year period covering two complete
annual cycles of 2003-2004. The monsoon regions are the most important socio-economically in terms of devastation by floods
and droughts, and potential impacts from climate change and fluctuations of the hydrologic cycle. Scientifically, it is most
challenging, because of complex interactions of atmosphere, land and oceans, local vs. remote forcings in contributing to
climate variability and change in the region. Given that many common features, and physical teleconnection exist among
different monsoon regions, an international research focus on monsoon must be coordinated and sustained. Current models of
the monsoon are grossly inadequate for regional predictions. For improvement, models must be confronted with relevant
observations, and model physic developers must be made to be aware of the wealth of information from existing climate data,
field measurements, and satellite data that can be used to improve models. Model transferability studies must be conducted.
CIMS is a major initiative under CEOP to engage the modeling and the observational communities to join in a coordinated
effort to study the monsoons. The objectives of CIMS are (a) To provide a better understanding of fundamental physical
processes (diurnal cycle, annual cycle, and intraseasonal oscillations) in monsoon regions around the world and (b) To
demonstrate the synergy and utility of CEOP data in providing a pathway for model physics evaluation and improvement. In
this talk, I will present the basic concepts of CIMS and the key scientific problems facing monsoon climates and provide
examples of common monsoon features, and possible monsoon induced teleconnections linking different parts of the world.
