Expectations to YOPP � Establish sustainable observation system in the Arctic and Antarctic.
� Connect observation and modelling more closely. � Improve polar prediction ability, especially sea ice. � Strengthen international cooperation with relevant institutions�
Contributions to YOPP - 1 � Observations
ü Frequent surface and radiosonde meteorological observations Using R/V Xuelong, polar research stations, and other AWS.
ü More sea ice-‐ocean observations based on R/V Xuelong, fixed sea ice site and buoys: sea ice concentration, surface radiation, albedo, eddy fluxes, snow and sea ice mass balance (IMBs), water temperature and salinity
ü International synergistic observations during YOPP
Ø Coordinate Chinese Arctic and Antarctic Administration (CAA);
Ø Chinese Arctic Cruise in 2018 (TBD)
Contributions to YOPP - 2 � Prediction
ü High resolution atmosphere and ice-‐ocean coupled forecasts: < 5 km in key interesting regions ü Data assimilation: simple Nudging, and Ensemble Kalman Filter based sea ice – ocean data assimilation
ü Arctic and Antarctic sea ice seasonal outlook (statistical method) ü Forecasting service for Arctic and Antarctic shipping ü sharing the data with YOPP partners.
� Education and Outreach ü More engagement of Young researchers and PhD students (> 20 persons) ü We are happy to host PPP-‐SG meeting in 2016, or some related workshops/summer school on polar prediction during YOPP period.
� Strengthen international cooperation to improve polar prediction ability.
� Sustainable observation system for both YOPP and the time beyond.
� Identifying verification metric for sea ice prediction is an urgent issue.
