This visualization shows the finite-time Lyapunov exponent (FTLE) field over Germany. The underlying simulation was computed within the HD(CP)² project
and the data was made available for the IEEE Scientific Visualization Contest 2017
. Our submission to the contest can be found here
The FTLE field is an indicator for hyperbolic Lagrangian coherent structures, which act as transport barriers in vector fields. In this visualization, altitude is reversed (ground is at the top) and North is right. The visualization shows the turbulent movement near the ground and updraft columns towards higher altitude. The FTLE layer at high altitudes (bottom) is the tropopause, which is the boundary between troposphere and stratosphere.
