The initial results of the first computer model that simulates the global atmosphere with a detailed representation of individual clouds have been analyzed by a team of scientists at the International Pacific Research Center (IPRC) at the University of Hawai`i at Mānoa, Japan-Agency for Marine Earth Science and Technology (JAMSTEC), and the University of Tokyo. The model, called the Nonhydrostatic ICosahedral Atmospheric Model (NICAM), was developed for the supercomputer Earth Simulator at JAMSTEC. Given the atmospheric conditions that were present 1-2 weeks before the observed cyclones formed, the model successfully reproduced the birth of two real tropical cyclones that formed in the Indian Ocean in December 2006 and January 2007.
