SEATTLE, WA -- (MARKET WIRE) -- 06/05/2006 -- Global supercomputer leader Cray Inc. (NASDAQ: CRAY) today announced that the Earth System Research Center (ESRC), a cooperative venture between Cray and the Korea Meteorological Administration (KMA), has funded a second round of projects that promise to benefit public welfare by improving weather, seasonal climate and natural disaster predictions. ESRC was established in 2005 to advance the science of earth-system modeling over the East-Asia Pacific region and to leverage the collective knowledge of academia, government and industry in Korea by promoting collaboration across the representative communities.

Researchers sponsored by ESRC will use the Cray X1E™ supercomputer at KMA, which is the fastest operational numerical weather prediction system in the world, to pursue a variety of earth science studies. Announced projects include:

--  Development of a flux coupler for the Earth Systems Model at the
    Korea Institute of Science and Technology that will help optimize modeling
    by combining results from different model subsystems.
--  Design of an efficient meteorological data-sharing system
    architecture in a grid environment, to be developed by Kyung Hee
    University.
--  Launch of a Local Analysis and Prediction System for use by the
    Republic of Korea Air Force.
--  Optimization and sensitivity experiments based on the pre-
    processing module in a Weather Research and Forecasting (WRF) model, to be
    conducted by Bukyung University.
--  Simulation of the Mesoscale Eddy Field using the High-Resolution
    Oceanic General Circulation Model, an analysis to be provided by Yon Sei
    University.
--  Development and optimization of the Boltzmann Integral Exact
    Solution algorithm by the Meteorological Research Institute (METRI)'s Ocean-
    Earthquake Laboratory, an organization within KMA.
--  Investigation of short-range ensemble precipitation forecasts
    using Initial Conditions and Model Physics Perturbation in a WRF model,
    conducted by the METRI Forecast Research Laboratory.
--  Development of a boundless storm surge and tide dynamic coupling
    model by Inha University.
    

"ESRC continues to fulfill its goal of advancing the science of earth-system modeling for the East-Asia Pacific region on several fronts, as well as promoting collaboration in the Korean academic community," said Dongil Lee, chief of the Supercomputer Center at KMA. "The new studies that have recently been launched provide an excellent example of the range and depth of the research efforts that the KMA and Cray collaboration is encouraging. We look forward to benefiting from the incredibly valuable knowledge that will be gained from these projects."

"Cray and KMA have joined forces in creating a major center for furthering research in a scientific field that has become critical to the welfare of people and societies around the world," said Per Nyberg, Cray's Earth Sciences Segment director. "This new round of studies conducted in Korea under the auspices of the ESRC are sure to result in important advances in weather forecasting, climate modeling and natural disaster prediction."
