Month-long Predictability of Madden-Julian Oscillation (MJO) Demonstrated on K Computer Using Highly Complex New-generation Global Model

A joint research team consisted of the Japan Agency for Marine-Earth Science Technology (JAMSTEC: Asahiko Taira, President), the University of Tokyo, and Riken, led by Dr. Tomoki Miyakawa, Postdoctral Researcher (Basic Research Area/Coupled Ocean-Atmosphere-Land Process Research, JAMSTEC) and Professor Masaki Satoh (Atmosphere and Ocean Research Institute, the University of Tokyo) demonstrated that the Nonhydrostatic Icosahedral Atmospheric Model (NICAM)  on the supercomputer K is effective for month-long forecasts of the Madden-Julian Oscillation (MJO), a huge eastward propagating atmospheric pulse that affects the entire globe.
