Dr Huiyi Yang

BSc, PhD
Biography

Huiyi Yang joined  NRI in May 2020. His research focuses on using modelling approaches to understand climate change and air pollution impacts on crop production and food security, especially for those regions most vulnerable to climate change.  He also has interests in assessing uncertainty and adaptation approaches to climate change.

Huiyi obtained his BSc and PhD from the University of Leeds. He initially trained in climate and atmospheric science and then expanded his research into climate change impacts on agriculture through his work at the University of Exeter and Rothamsted Research. This broadening of expertise has made  his work more interdisciplinary and has positioned him well for  contributing substantively to this growing area of research.

Huiyi has extensive experience in numerical modelling. He developed a new crop (i.e. winter wheat) within the Met Office Land Surface Model (LSM) JULES/JULES-Crop and evaluated the air pollution impacts on crop yield/production and the regional carbon cycle. He used the GLAM crop model to access the crop yield and failure rates for the East Asian Monsoon region under a geoengineered climate. He also used the SPACSYS model to simulate the crop rotation system for the Loess region.

Huiyi began his career studying radiation effects on the atmosphere using an LEM model focusing on evaluating the response of the atmosphere to using observed ice particle shapes in radiation rather than the often-used idealised shapes.   Huiyi has been involved in many international modelling projects, including developing a case study for a model inter-comparison project on cirrus clouds (GCSS WG2).

Huiyi’s research interests focus on interaction between agriculture, climate and humans. He is interested in developing a better understanding of:

  • Development and evaluation of LSM and crop models by using observational data from field experiments.
  • The impact of climate (e.g CMIP, GeoMIP etc) and environmental factors (ozone, aerosol, etc) on crop yield/production, and the consequent social-economic impacts.
  • Evaluating the feasibility of adaptations under different weather conditions especially brought about by climate change, such as drought or high temperature.
  • Regional and global impacts on water, carbon, and the nitrogen cycle due to climate change.

Field experimental science is fundamental and of vital importance for underpinning modelling work. This is still the key challenge for modelling communities to understand the impact of climate and environmental changes on agriculture and human societies properly. To fulfil the gap, Huiyi has collaborated closely with field scientists to develop and evaluate models. Huiyi is also interested in combining statistics with LSM and crop models to improve model predictions.
