Abstract:
An ensemble optimal interpolation (EnOI) data assimilation method is applied in the BCC_CSM1.1 to investigate the impact of ocean data assimilations on seasonal forecasts in an idealized twin experiment framework. Pseudo-observations of sea surface t...
Analysis and comparison of heat flux of landfast ice during 2016 in the Prydz Bay, Antarctica
Guanghua Hao, Jie Su, Qinghua Yang, Long Lin, Shutao Cao
2021, 40(5): 71-79. doi: 10.1007/s13131-021-1731-4
Abstract:
Long term in situ atmospheric observation of the landfast ice nearby Zhongshan Station in the Prydz Bay was performed from April to November 2016. The in situ observation, including the conventional meteorological elements and turbulent flux, enabled...
