Hao Zuo

Senior Scientist Ocean Data Assimilation
Research, Earth System Assimilation, Coupled Assimilation

Summary:

Hao Zuo is responsible for Ocean Analysis System at ECMWF. He implements and maintains the latest operational Ocean Analysis-Reanalysis System (OCEAN5), which is used to initialize the ocean and sea-ice components of all ECMWF coupled forecasting systems (ENS, HRES, Seasonal). Hao is also in charge of integrating ocean observations (in-situ, SST, sea ice, SSH) into the ECMWF System for Earth System assimilation and carrying out Observing System Experiments for impact studies. Hao is the PI on a CMEMS service evolution project to evaluate the Benefits of dynamically modelled river discharge input for ocean and coupled system (BRONCO). He is also involved in several other research projects, including the EU H2020 AtlantOS and SPICES, the ESA Sea Level Climate Change Initiative (CCI), the EU FP7 MyOcean and MyOCEAN2, the Copernicus Marine Environment Service (CMEMS) GloRan.  Research interests include  assessment of ocean analysis system in the sense of coupled forecasting system, and study of climate signals derived from changes in sea-level, heat content, sea ice and other ECVs.

Professional interests:

My research interests include

  • Application of ocean analysis in NWP and climate monitoring
  • Ocean data assimilation and and ensemble generation
  • Uncertainty in climate signals derived from observations and retrospective analysis
  • Ocean overturning circulation and mixing process.
  • Heat content and freshwater budget in the ocean
