DESCRIPTION:We present a finite element framework that extends the mimetic
  approach of Ringler\, Thuburn\, Skamarock and Klemp (2010) to finite elem
 ent methods. The framework preserves the following benefits of the mimetic
  approach: local mass conservation\, steady geostrophic linear modes on th
 e f-plane\, consistent conservative potential vorticity advection\, but al
 lows for selection of higher-order finite element discretisations and adju
 stment of the balance of vorticity and mass degrees of freedom. We will ex
 plain the foundations of the framework and present some preliminary numeri
 cal results which form part of the UK Met Office/NERC/STFC GungHo dynamica
 l core project.\n\n
