[HTML][HTML] Stochastic parameterization: Toward a new view of weather and climate models

J Berner, U Achatz, L Batte… - Bulletin of the …, 2017 - journals.ametsoc.org
The last decade has seen the success of stochastic parameterizations in short-term, medium-
range, and seasonal forecasts: operational weather centers now routinely use stochastic …

A generic approach to explicit simulation of uncertainty in the NEMO ocean model

JM Brankart, G Candille, F Garnier… - Geoscientific Model …, 2015 - gmd.copernicus.org
In this paper, a generic implementation approach is presented, with the aim of transforming
a deterministic ocean model (like NEMO) into a probabilistic model. With this approach …

Relationships between Arctic sea ice drift and strength modelled by NEMO-LIM3. 6

D Docquier, F Massonnet, A Barthélemy… - The …, 2017 - tc.copernicus.org
Sea ice cover and thickness have substantially decreased in the Arctic Ocean since the
beginning of the satellite era. As a result, sea ice strength has been reduced, allowing more …

A comparison of data‐driven approaches to build low‐dimensional ocean models

N Agarwal, D Kondrashov, P Dueben… - Journal of Advances …, 2021 - Wiley Online Library
We present a comprehensive inter‐comparison of linear regression (LR), stochastic, and
deep‐learning approaches for reduced‐order statistical emulation of ocean circulation. The …

Calibration of sea ice dynamic parameters in an ocean‐sea ice model using an ensemble Kalman filter

F Massonnet, H Goosse, T Fichefet… - Journal of Geophysical …, 2014 - Wiley Online Library
The choice of parameter values is crucial in the course of sea ice model development, since
parameters largely affect the modeled mean sea ice state. Manual tuning of parameters will …

[HTML][HTML] Progress towards a probabilistic Earth system model: examining the impact of stochasticity in the atmosphere and land component of EC-Earth v3. 2

K Strommen, HM Christensen… - Geoscientific Model …, 2019 - gmd.copernicus.org
We introduce and study the impact of three stochastic schemes in the EC-Earth climate
model: two atmospheric schemes and one stochastic land scheme. These form the basis for …

Seasonal to annual ocean forecasting skill and the role of model and observational uncertainty

S Juricke, D MacLeod, A Weisheimer… - Quarterly Journal of …, 2018 - Wiley Online Library
Accurate forecasts of the ocean state and the estimation of forecast uncertainties are crucial
when it comes to providing skilful seasonal predictions. In this study we analyse the …

[HTML][HTML] Improved teleconnection between Arctic sea ice and the North Atlantic Oscillation through stochastic process representation

K Strommen, S Juricke, F Cooper - Weather and Climate …, 2022 - wcd.copernicus.org
The extent to which interannual variability in Arctic sea ice influences the mid-latitude
circulation has been extensively debated. While observational data support the existence of …
