Genesis of the NT Tropical Depression January 2006

Wind vectors, relative vorticity and Okubo-Weiss contours at 500 mb

The left panels show wind vectors and contours of the relative vorticity during the genesis and inmtensification stages of the disturbance. Contour levels for the zonal wind are 5 m s-1. Regions with westerly zonal velocity component exceeding 5 m s-1 are shaded pink; regions with easterly zonal velocity component exceeding 5 m s-1 are shaded light blue. The right panels show wind vectors and contours of the Okubo-Weiss. Contour levels for the relative vorticity are 5 m s-1. Regions with positive values exceeding 5 m s-1 are shaded pink; regions with negative values exceeding 5 m s-1 in magnitude are shaded light blue. FIX REL VORT MAGNITUDES
