Selected Publications

A time sequence of visible satellite images from 5 June 1986
showing a beautiful example of a mesoscale-convective instability process.
For more information, please see the Monthly Weather Review article by Jascourt et al. (1988) ,

Visible satellite images (2 km resolution) on 5 June 1986 at (a) 1631, (b) 1701, (c) 1801 and (d) 1931 UTC.
Note development of five convective bands across western Louisiana by 1801 UTC.
Active convection was occurring along entire length of bands.
After 1930 UTC, anvil cirrus obscured banded structure.
