Jorge Lindley


I am from the United Kingdom and I completed my MMATH at the University of Warwick in 2012, where I continue to study within MASDOC. After completing the MSc year provided by the MASDOC course, I am now in my third year of the PhD project.


Academic Interests

My interests are in numerical analysis, computing and atmospheric dynamics. I completed my MSc dissertation "Enstrophy and Temperature Gradient Production for Vortices in Stratified Flow" with Robert Kerr and Andreas Dedner. This project involved the investigation of an instability that can occur between two vortices in a stratified fluid. The idea behind this was to try and show that baroclinic enstrophy production within the zig-zag instability that forms could be one possible mechanism for the $k^{-5/3}$ energy spectrum observed at small scales in the atmosphere. This energy spectrum is not refelcted in current forecast models and no one knows why.

I continue to work with Robert Kerr and Andreas Dedner to build a simple atmospheric model using Finite Element Methods in DUNE (Distributed and Unified Numerics Environment). We investigate the role of Quasi-geostrophic frontogenesis in the formation of the $k^{-5/3}$ energy spectrum.

Front formation can be acheived by imposing a horizontal deformation field upon a meridional (North-South) temperature gradient with the axis of contraction perpendicular to isothermal lines as in Figure 1. Over time these gradients are intensified by the deformation field creating a frontal zone.


Initial State

(contours) at z = 900m.


Front Formation
Figure 2: Formation of a front at t = 30hrs. Strong temperature gradients can be seen
at y = 3600km between x = 2160 - 6480km. The deformation field and front formation
have drifted East due to the geostrophic winds that form to balance the meridional
temperature gradient.

Other Interests

I take part in the sport of archery at a competitive level, representing the University at a variety of competitions. I also enjoy martial arts and have trained at the Kempo Jujitsu and Jitsu clubs here at Warwick. I like to play other sports as well such as tennis or badminton when time permits it.
