News

With time, I hope to post usage, papers, etc. which relate to MiMA here. If you’re a MiMA user, please let me know of any news at coding@martinjucker.com.

• February 2020: New release (v1.1) adds restart from arbitrary initial conditions (as used in Yamada and Pauluis (2017) below) and possibility to use the Navy high-resolution land-sea mask.
• January 2020: Two new papers published using MiMA for research on climate dynamics. These papers have further developed MiMA and their additions will be published in the upcoming v2.0:
  • Garfinkel, C.I., I. White, E.P. Gerber, M. Jucker, and M. Erez (2020): The building blocks of Northern Hemisphere wintertime stationary waves, Journal of Climate, doi:10.1175/JCLI-D-19-0181.1 which, among other important findings, shows that MiMA is just as good as any CMIP5 model to represent Northern Hemisphere stationary waves.
  • White, I.P., C. Garfinkel, E. Gerber, M. Jucker, P. Hitchcock, and J. Rao (2020): The generic nature of the tropospheric response to sudden stratospheric warmings, Journal of Climate, doi: 10.1175/JCLI-D-16-0703.1 which examines the evolution of naturally occurring versus synthetically forced Sudden Stratospheric Warmings.
• August 2019: Iceberg article about MiMA’s various choices for mixed layer depth and albedo distribution: The surface of an aquaplanet GCM. PDF: doi.org/10.5281/zenodo.3358284
• March 2018: Isca framework (which contains MiMA) reference paper published in Geoscientific Model Development: Vallis et al., 2018: Isca, v1.0: a framework for the global modelling of the atmospheres of Earth and other planets at varying levels of complexity, Geosci. Model Dev., doi:10.5194/gmd-11-843-2018
• February 2018: Talk and poster about MiMA at the 2nd Pan-GASS meeting. The poster can be viewed here.
• August 2017: Bugfix patch (v1.0.1) addresses incoming SW radation bugs.
• June 2017: Ray Yamada and Olivier Pauluis use MiMA for baroclinic lifecycle studies: Yamada, R., and O. Pauluis, 2017: Wave-mean-flow interactions in moist baroclinic lifecycles. J. Atmo. Sci., 74, 2143-2162, doi:10.1175/JAS-D-16-0329.1
• June 2017: MiMA reference paper published in Journal of Climate: M Jucker and EP Gerber, 2017: Untangling the annual cycle of the tropical tropopause layer with an idealized moist model, J Clim, doi:10.1175/JCLI-D-17-0127.1.
