Post-doc on improving simulations and predictions in the tropical Atlantic
A 2-year post-doc position in climate modelling is available at Uni Climate. Situated at the University of Bergen, Uni Climate is a department of Uni Research AS and partner of the Bjerknes Centre for Climate Research (BCCR), a collaboration between Uni Research AS, the University of Bergen, the Institute of Marine Research and the Nansen Environmental and Remote Sensing Center. The position is within the EU FP7 project “PREFACE”.

The Tropical Atlantic (TA) is a critical area of both historical and future climate change. Environmental palaeo-records indicate large decadal-to-millennial fluctuations with large impacts on the surrounding continental areas. Understanding the origin, the mechanism, and the predictability of such changes, and the correct interpretation of palaeo-records, all rely largely on the ability of numerical models to simulate the climate of the TA and its coupled variability. Similarly, seasonal-to-decadal (s2d) forecasting is seen as an increasingly important area of climate research, with potential to substantially mitigate the socio-economic impacts of future climate variations.
With this in mind, Uni Research AS will participate in the EU FP7 project "PREFACE" to support a process-based evaluation and development of the NorESM model, in synergy with other modelling centres, towards a consistent performance on time-scales from seasons to millennia, while interacting with the European climate-modelling community towards improving our understanding of the climate of the TA and its variability.

Work description
We are seeking a candidate to conduct research aimed at investigating mechanisms responsible for the development of systematic biases in coupled General Circulation Models (GCMs). A focus will be placed on the area of the TA and especially its oceanic upwelling regions.
Initially, an analysis will be conducted of the systematic drift in existing s2d hindcasts integrations that are initialised from observations (Toniazzo and Woolnough, 2013), using high-frequency diagnostic output in both oceanic and atmospheric components.
Sensitivity experiments will then be conducted with the Norwegian Earth-system model (NorESM) and the UK Met Office Hadley-Centre global environmental model (HadGEM) in s2d hindcast mode to isolate relevant mechanisms and the influence of specific processes and model parametrisations on bias development.
Convective heating over either nearby continental land-masses or over the Indo-Pacific sector; atmospheric radiative tendencies and cloud feedbacks; oceanic advection and wave dynamics; PBL-mixed-layer interactions; these are all aspects of the model simulations which may be subject to analysis and experimentation, with the final aim of  identifying modelling areas where improvements can lead to significantly better model simulations. Some of the experiments will be also conducted in "climate" mode to investigate impacts on the simulated inter-annual variability.
Close collaboration with UiB and the University of Reading is planned, and a two-way interaction with NorESM model development is envisaged. The applicant will benefit from the European and African collaborative framework of the EU FP7 “PREFACE” project.
