As one of the meteorological support teams for the Winter Olympics, the Institute of Atmospheric Physics (IAP) of the Chinese Academy of Sciences (CAS) is providing event planners with a detailed forecast of wind, temperature, and snow. The usual weather forecasts cover as much as 10 kilometers or more. For competition area in Chongli County, Zhangjiakou in North China’s Hebei Province, CAS’s IAP zoomed in into 450 square meter grids, and generated hourly forecasts for each one. In addition, a prediction system called FGOALS-f2 seamless prediction system, also developed by CAS’s IAP, can ascertain climate patterns for as long as six months into the future. FGOALS-f2 predicted that the average temperature in February 2022 would be warmer than usual by 1-2 degrees Celsius. For the 2022 Winter Olympics organizers, this one-degree difference can impact decisions and planning. Both long-term and short-term prediction for the event are paired with CAS’s IAP supercomputer power, which can not only achieve hundred-meter-level prediction, but also process six kinds of elements in the clouds and use the Resolving Convective Precipitation Scheme to get highly accurate results.
