• A chromospheric resonance cavity in a sunspot mapped with seismology 

  Jess, DB; Snow, B; Houston, SJ; et al. (Nature Research, 2 December 2019)

  Sunspots are intense collections of magnetic fields that pierce through the Sun’s photosphere, with their signatures extending upwards into the outermost extremities of the solar corona1. Cutting-edge observations and ...

• Natural drivers of multidecadal Arctic sea ice variability over the last millennium 

  Halloran, PR; Hall, IR; Menary, M; et al. (Nature Research, 20 January 2020)

  The climate varies due to human activity, natural climate cycles, and natural events external to the climate system. Understanding the different roles played by these drivers of variability is fundamental to predicting ...

• Compatible finite element spaces for geophysical fluid dynamics 

  Natale, A; Shipton, J; Cotter, CJ (Oxford University Press, 22 November 2016)

  Compatible finite elements provide a framework for preserving important structures in equations of geophysical fluid dynamics and are becoming important in their use for building atmosphere and ocean models. We survey the ...

• Higher-order compatible finite element schemes for the nonlinear rotating shallow water equations on the sphere 

  Shipton, J; Gibson, TH; Cotter, CJ (Elsevier, 17 September 2018)

  We describe a compatible finite element discretisation for the shallow water equations on the rotating sphere, concentrating on integrating consistent upwind stabilisation into the framework. Although the prognostic variables ...

• Fluctuations of finite-time Lyapunov exponents in an intermediate-complexity atmospheric model: a multivariate and large-deviation perspective 

  Kwasniok, F (European Geosciences Union, 31 July 2019)

  The stability properties as characterized by the fluctuations of finite-time Lyapunov exponents around their mean values are investigated in a three-level quasi-geostrophic atmospheric model with realistic mean state and ...
