2 Dust cycle and associated processes Dust global distribution Annual mean frequency distribution of MODIS Deep Blue ( ) Dust Optical Depth (DOD) > 0.2 (brown colour scale), TOMS ( ) Aerosol Index (AI) > 0.5 (blue contour lines), and OMI ( ) AI > 0.5 (green contour lines). The isocontours of TOMS and OMI have been removed over oceans for clarity. Extracted from Ginoux et al. (2012, JGR) 2
3 Dust cycle and associated processes: Types of dust storms Synoptic dust storms (large scale weather systems) Pre-frontal winds Post-frontal winds Large-scale trade winds Mesoscale dust storms Downslope winds Gap flow Haboobs 3
4 Dust cycle and associated processes Dust Impacts Meteorology and climate Marine productivity Coral mortality Hurricanes formation Air Quality and Human Health Respiratory disease (asthma) Eye infections Meningitis in Africa Valley Fever in the Americas Aviation and Ground Transportation Low visibility (i.e. air disasters) Agriculture Image from WMO website ( Energy and industry 4
5 Dust forecasting models Dust models are a mathematical representation of atmospheric dust cycle. To complement dust-related observations, filling the temporal and spatial gaps of the measurements. To help us to understand the dust processes and their interaction with climate and ecosystems. To predict the impact of dust on surface level concentrations used as SHORT-TERM FORECASTING TOOLS (3-5 days ahead) Extracted from Shao (2008) 5
