The Polar Prediction Project(PPP,2013-2022)and Year of Polar Prediction(YOPP,mid-2017to mid- 2019)were initiated by the World Meteorological Organization(WMO),to effectively tackle the challenges of global climate change and polar warming.Eight key research goals,e.g.,user applications and societal benefit, verification,observations,modelling,data assimilation,ensemble forecasting,predictability and forecast error diagnosis, global linkages,as well as the selected activities were discussed.Suggestions related to the in-situ observation, numerical prediction and information service,are also given to the Chinese polar research community to well take this opportunity of the PPP/YOPP implementation.
