Journal ArticleDOI
Finite-Element Sea Ice Model (FESIM), version 2
Sergey Danilov,Qiang Wang,Ralph Timmermann,Nikolay Iakovlev,Dmitry Sidorenko,Madlen Kimmritz,Thomas Jung,Jens Schröter +7 more
TL;DR: In this article, the elastic-viscous-plastic (EVP) solvers and viscousplastic solvers were used for the Finite Element Sea Ice Model (FESIM).
Journal ArticleDOI
On the convergence of the modified elastic-viscous-plastic method for solving the sea ice momentum equation
TL;DR: The question of convergence of this modified EVP method is revisited and it is shown that convergence is reached provided the stability requirements are satisfied and the number of pseudotime iterations is sufficiently high.
Journal ArticleDOI
Optimising assimilation of sea ice concentration in an Earth system model with a multicategory sea ice model
Madlen Kimmritz,Francois Counillon,Cecilia M. Bitz,François Massonnet,Ingo Bethke,Yongqi Gao +5 more
TL;DR: A data assimilation method capable of constraining the sea ice of an Earth system model in a dynamically consistent manner has the potential to enhance the accuracy of climate reconstructio... as mentioned in this paper.
Posted ContentDOI
NorCPM1 and its contribution to CMIP6 DCPP
Ingo Bethke,Yiguo Wang,Francois Counillon,Francois Counillon,Noel Keenlyside,Noel Keenlyside,Madlen Kimmritz,Filippa Fransner,Annette Samuelsen,Helene R. Langehaug,Lea Svendsen,Ping-Gin Chiu,Leilane Passos,Leilane Passos,Mats Bentsen,Chuncheng Guo,Alok Kumar Gupta,Jerry Tjiputra,Alf Kirkevåg,Dirk Jan Leo Oliviè,Øyvind Seland,Julie Solsvik Vågane,Yuanchao Fan,Tor Eldevik +23 more
TL;DR: In this paper, the authors describe the Earth system component and the data assimilation (DA) setup of the NorCPM1 model, highlighting implementation of new forcings, bug fixes, retuning and DA innovations.
Journal ArticleDOI
Seasonal predictions initialised by assimilating sea surface temperature observations with the EnKF
Yiguo Wang,Francois Counillon,Noel Keenlyside,Noel Keenlyside,Lea Svendsen,Stephanie Gleixner,Madlen Kimmritz,Panxi Dai,Yongqi Gao,Yongqi Gao +9 more
TL;DR: In this article, the authors employ the Norwegian Climate Prediction Model (NorCPM) to assimilate SST observations with the ensemble Kalman filter and show that the skill is largely derived from the initialisation rather than from the external forcing.
