Martin Best
Hadley Centre Met Office (UK)
Dr Best leads the group working on land surface processes at the UK Met Office. He also leads the development of Joint UK Land Environment Simulator (JULES), a community land surface model. Dr Best is also the lead on two international community experiments. The first is related to the benchmarking of land surface models and aims to identify the common development priorities for these models. The second is investigating the coupling between the land surface and the atmosphere in an attempt to understand what controls the sensitivity of this coupling in numerical models. Other activities contribute towards the analysis of results from the first urban model comparison project. This aims to improve our understanding of the important physical processes within urban environments and improve the way in which we represent them.

Dr Best has a strong interest in developing a hydrological framework for future land-surface modelling and will collaborate with the Australian community to ensure developments are shared between JULES and the Community Atmosphere Biosphere Land Exchange Model (CABLE). His work will have a direct impact on the capacity of land models to simulate drought and feedback of soil moisture on heatwaves. For this reason his contribution to the Centre of Excellence will be focused in the Drought and Heatwaves and Cold Air Outbreaks research programs.

Robert Hallberg
GFDL

Dr Hallberg developed the “Generalized Ocean Layer Dynamics” (GOLD) model, which is the physical ocean model basis of GFDL’s ESM2G Earth System Model. He is now part of the team focusing all of its ocean model development efforts on a single model, MOM6.  He and his team have examined the role of transient eddies in the dynamic and watermass balances in the Southern Hemisphere with a series of increasingly high resolution primitive equation model simulations.

Dr Hallberg is now working to dynamically couple GFDL’s highest resolution global ocean models to continental scale ice-sheet models, including smoothly moving grounding lines and dynamic reshaping of the ice-shelf cavities.  He is also involved an Ocean Climate Process Team working on Internal Wave Driven Mixing, and in the past was an active participant in two other Climate Process Teams – one studying Gravity Current Entrainment, and the other examining Eddy-Mixed Layer Interactions. These teams aim to improve the representation of these processes in climate-scale models, based on the best understanding that can be obtained from observations, process studies, and theory.

Dr Hallberg’s seminal contributions to deep ocean flows, Southern Ocean circulation and mixing processes around topography will allow him to apply this expertise to the Southern Ocean component of the Climate Variability and Teleconnections research program.

Cathy Hohenegger
(Max-Planck-Institut für Meteorologie)

Dr Cathy Hohenegger’s research combines models at all resolutions to better understand and improve the representation of precipitating convection in atmospheric models. She tackles the convection problem both from a small-scale process level perspective, trying to better understand the processes that control the lifecycle of convection, and from a large-scale more climatic perspective, trying to understand the importance of specific convective features for the climate system.

Dr Hohenegger routinely uses large-eddy simulations with resolutions of ~100 m where convection is fully explicit, convection-permitting models with resolution ~1-10 km where convection is partly explicit and coarser resolution models with parameterized convection. Her research also often makes use of idealized simulations before testing the so developed theories in more realistic set-ups.

She will be ideally placed to contribute to the Extreme Rainfall program through her leadership of the MPI group that carries out high-resolution cloud model experiments that study the behaviour of convective organisation.

In particular, Mr Milton works across a broad range of global modelling activities with a focus on diagnosing global model systematic errors and performance against a range observational satellite and in-situ observations across weather and climate prediction timescales. In this role he co-ordinates the trialling and pull-through of improvements in model physics, dynamics, and resolution. He also develops and applies new diagnostic techniques to help understand the source of model systematic error growth and produce seamless predictions by promoting the development of the global numerical weather prediction model to include increasing earth system complexity, which is essential for short-term environmental prediction.

From 1997 Mr Milton led the Model Diagnostics and Validation team, which in 2002 became the Forecast model development and diagnostics group. In 2008, he was awarded a Met Office Technical Research Fellowship, and in 2010 he became the head of the newly created Global Model Evaluation and Development section.

 

Mr Milton’s work with the Unified Model has a direct influence on Australia’s ACCESS model, which uses the atmospheric component of the UM. As a result, Sean’s work touches on all of the research programs of the Centre of Excellence for Climate Extremes. However, much of the focus of his work with the Centre is likely to be on the Extreme Rainfall and Heatwave and Cold Air Outbreaks programs.

Joellen Russell
(University of Arizona)

Dr Joellen Russell’s work on the westerly winds led to the creation of a new paradigm in climate science, namely that warmer climates produce stronger westerly winds. This insight solved one of the long-standing climate paradoxes, the mechanism responsible for transferring one-third of the carbon dioxide in the atmosphere into the ocean and then back out again during our repeated glacial-interglacial cycles.

Her current research focuses around understanding the ocean’s role in the climate system, in particular the uptake of heat and carbon in the Southern ocean, using the latest high-resolution models from the National Oceanic and Atmospheric Administration’s Geophysical Fluid Dynamics Laboratory (NOAA/GFDL). She is the lead investigator for the modelling component of the Southern Ocean Carbon and Climate Observations and Modelling program and plays key leadership roles in a host of other international programs.

(NASA-Goddard Space Flight Centre)

Dr Joe Santanello’s research focuses on the development and application of metrics and tools to quantify and improve the understanding of Local Land-Atmosphere Coupling (LoCo) in models and observations. He currently chairs a workgroup to coordinate international efforts to diagnose and improve this coupling in models from local to global scales. This work is supported by NASA’s Energy and Water Cycle Study (NEWS) and has been the leading component of the GEWEX-GLASS LoCo initiative that has gained momentum over the past decade

Dr Santanello was also the Land Team lead for the NASA Unified WRF (NU-WRF) modelling system/project, which includes coupling NASA’s Land Information System (LIS) and facilitates model-data fusion research in the realm of land data assimilation (e.g. soil moisture) and land surface model calibration (e.g. surface fluxes).

He has investigated the ability of satellite remote sensing to routinely monitor the planetary boundary layer for land surface and land-atmosphere studies, including engagement of the AIRS, CALIPSO, GPS-RO mission science teams.

His expertise in very high-resolution regional scale modelling provides specific skills that can be focused primarily in two Centre research areas – Heatwaves and cold air outbreaks, and Drought. The Centre’s aim to improve land surface schemes to include irrigation, urbanization, fire etc is also a common goal. Dr Santanello will contribute to improving the regional terrestrial feedbacks of energy, water, carbon in the context of their impact on extremes, particularly droughts and heatwaves.

Ying Ping Wang
(CSIRO)

Dr Wang has been a chief research scientist in CSIRO since 2015. His major achievements include the joint development of the Australian community land model (CABLE), two-leaf canopy scheme, the unified theory of global nitrogen fixation, and the first global model of carbon, nitrogen and phosphorus cycles. He also pioneered the applications of model-data fusion in terrestrial ecology.

His main research interests are global land modelling, global biogeochemical cycles, land use change, nutrient limitation, model-data fusion and model benchmarking.

He is an associate editor for Agriculture and Forest meteorology since 2010.

Dr Wang will contribute primarily to our research programs on Heatwaves and cold air outbreaks and Drought. His specific research contribution is likely to be focused on the role of leaf phenology in controlling evapotranspiration. This area is relatively poorly represented in all global land surface models and, in reality, acts as a significant control on transpiration as ecosystems experience drought-related stress, particularly for Australian evergreen vegetation. Another important contribution is likely to focus on the effect of nutrient availability limiting the response of vegetation to increasing atmospheric carbon dioxide. The CABLE model is the first and one of a very few global land models that simulates phosphorus cycle, a very important process for the Australian terrestrial ecosystems.
