Forecasting and early warning of dust storms http://na.unep.net/geas/archive/pdfs/GEAS_Feb2013_DustStorm.pdf
This month's Bulletin of the United Nations Environmental Programme's
Global Environmental Service focuses on dust storms. We've been
seeing the consequences of those in SW Colorado in recent years, as
they leave a layer on snow that then results in earlier snowmelt,
which then has significant effects on phenology and abundance of
flowering. The frequency of such events seems to be increasing.
