The 48 h WCB trajectories for the dichotomous WCB case described by Martínez-Alvarado et al. (2014), located between 500–800 hPa at 00:00 UTC on 25 November 2009 (black dots) and ascending cyclonically (green), anticyclonically (blue), or without a distinct curvature (orange). The letter “C” marks the position of the cyclone center, and the grey contours show SLP (every 4 hPa) at 00:00 UTC on 25 November 2009.

Thermodynamic trajectory classifications for (a)–(c) the Lower Valais, (d)–(f) the Hasli Valley, and (g)–(i) the Reuss Valley. Strongly heated airstream: right column; weakly heated airstream: centre column; cooled airstream: left column. The number of trajectories within each category and for each valley is given in the upper right corner.
