University of Reading

Senior Research Scientist (NCAS Climate)

Responsibilities:

I am an NCAS Senior Reseach Scientist at the University of Reading in the Global High-resolution Climate Modelling Group (HRCM), a long-standing collaboration between NCAS and the UK Met Office Hadley Centre.

Research Interests:

Simulating climate extremes
- mid-latitude extremes and their atmospheric drivers (e.g., blocking, post-tropical cyclones, Tibetan Plateau Vortices)
- climate model evaluation using process-based (e.g., feature tracking) and statistical (e.g., extreme value analysis) methods
- role of model resolution
Climates of Central and East Asia
Hydroclimatology
Observed land precipitation
- uncertainty in gridded datasets
- radar-gauge blending and climate reconstruction techniques

Current research projects:

DAHLIA (Newton Fund CSSP China, 2020-2021), investing dust-atmosphere-land interactions, including dust storms, over East Asia, with Claire Ryder (PI), and Laura Wilcox, Pier Luigi Vidale (Co-Is)
COSMIC (Newton Fund CSSP China, 2019-2021), evaluating a global and convective-scale climate model over China, with Andrew Turner, Nicholas Klingaman, Pier Luigi Vidale (Co-Is)
IMPROVE (Newton Fund WCSSP India, 2019-2021), investigating Indian monsoon orographic precipitation, with Andrew Turner (PI), and Thorwald Stein, Jennifer Fletcher, Andrew Ross, Stephen Griffiths (Co-Is)
PERCHANCE (Newton Fund CSSP China, 2018-2020), investigating atmospheric processes causing extreme East Asian Summer Monsoon precipitation, with Nicholas Klingaman (PI) and Andrew Turner, Kevin Hodges) (Co-Is)
PRIMAVERA (EU Horizon 2020, 2015-2020) involving 19 partners across Europe to advance high-resolution global climate modelling. PRIMAVERA is led by HRCM (PIs Pier Luigi Vidale and Malcolm Roberts). Our specific interests concern the representation in models of atmospheric blocking, tropical and post-tropical cyclones, the global water cycle, and extreme precipitation.

Previous research projects:

MESETA (Newton Fund CSSP China, 2015-2018), investigating Tibetan Plateau Vortices (TPVs), and Tibetan Plateau dynamic and thermodynamic forcing of the monsoon, with Andrew Turner (Co-I)
UPSCALE (UK on PRACE: weather resolving Simulations of Climate for globAL Environmental risk): In this project, we conducted global simulations of present and future climates at a very high model resolution (about 25 km grid spacing). We found that the simulation of some important phenomena (for example, tropical cyclones, blocking) critically depends on model resolution.

Current postdoctoral supervision

Julia Curio was/is a research scientist in the MESETA/PERCHANCE projects. Julia studies Tibetan Plateau Vortices including their structure, impacts, and representation in models.
Mark Muetzelfeldt is a research scientist in the COSMIC project and studies the diurnal cycle of precipitation in a global and convective-scale climate model.
Alex Baker is a research scientist in the PRIMAVERA project. Alex studies how the present and future North Atlantic jet and storm tracks and impacts over Europe depend on model resolution. A particular focus area are post-tropical cyclones. (with Pier Luigi Vidale)
Co-supervison of Ambrogio Volonté (COSMIC), Kieran Hunt (IMRPOVE), Amulya Chevuturi, Liang Guo (PERCHANCE)

Current graduate student supervision

Elliott Sainsbury is a NERC SCENARIO PhD student investigating post-tropical cyclones impacting Europe.
Sally Woodhouse is a NERC SCENARIO PhD student investigating fluxes of heat and freshwater into and out of the Arctic in coupled high-resolution versions of the MetUM climate model. (Lead supervision Len Shaffrey, also with Yevgeny Aksenov and Sheldon Bacon at the National Oceanography Centre)
Bernard Racoma is a PhD student, jointly at the University of the Philippines and at Reading, investigating Tropical Cyclones affecting the Philippines. (Lead supervision Nicholas Klingaman, also with Christopher Holloway)
