Persistent northward North Atlantic tropical cyclone track migration over the past five centuries (2016)
Journal Article
Baldini, L. M., Baldini, J. U. L., McElwaine, J., Frappier, A. B., Asmerom, Y., Liu, K. B., Prufer, K., Ridley, H. E., Polyak, V., Kennett, D. J., Macpherson, C. G., Aquino, V. V., Awe, J., & Breitenbach, S. F. M. (2016). Persistent northward North Atlantic tropical cyclone track migration over the past five centuries. Scientific Reports, 6, Article 37522. https://doi.org/10.1038/srep37522

Accurately predicting future tropical cyclone risk requires understanding the fundamental controls on tropical cyclone dynamics. Here we present an annually-resolved 450-year reconstruction of western Caribbean tropical cyclone activity developed usi...

The dynamics of surges in the 3 February 2015 avalanches in Vallée de la Sionne (2016)
Journal Article
Köhler, A., McElwaine, J., Sovilla, B., Ash, M., & Brennan, P. (2016). The dynamics of surges in the 3 February 2015 avalanches in Vallée de la Sionne. Journal of Geophysical Research: Earth Surface, 121(11), 2192-2210. https://doi.org/10.1002/2016jf003887

Five avalanches were artificially released at the Vallée de la Sionne test site in the west of Switzerland on 3 February 2015 and recorded by the GEOphysical flow dynamics using pulsed Doppler radAR Mark 3 radar system. The radar beam penetrates the... Read More about The dynamics of surges in the 3 February 2015 avalanches in Vallée de la Sionne.

Phase diagram for inertial granular flows (2016)
Journal Article
DeGiuli, E., McElwaine, J., & Wyart, M. (2016). Phase diagram for inertial granular flows. Physical Review E, 94(1), Article 012904. https://doi.org/10.1103/physreve.94.012904

Flows of hard granular materials depend strongly on the interparticle friction coefficient μp and on the inertial number I, which characterizes proximity to the jamming transition where flow stops. Guided by numerical simulations, we derive the phase... Read More about Phase diagram for inertial granular flows.

Modelling gravity currents without an energy closure (2016)
Journal Article
Konopliv, N., Llewellyn-Smith, S., McElwaine, J., & Meiburg, E. (2016). Modelling gravity currents without an energy closure. Journal of Fluid Mechanics, 789, 806-829. https://doi.org/10.1017/jfm.2015.755

We extend the vorticity-based modelling approach of Borden & Meiburg (Phys. Fluids, vol. 25 (10), 2013, 101301) to non-Boussinesq gravity currents and derive an analytical expression for the Froude number without the need for an energy closure or any...
