Question: What are the composite precipitation and surface temperature patterns when concentrations of dust are high or low in some regions?
Detemining Dust indices
- variable: BURDENDUST [kg/m2 ]
- Dust aerosol burden — total concentration of dust per meter square over a grid
- Dust aerosol burden — total concentration of dust per meter square over a grid
Defining High/Low Dust months
-
(High / Low): the months when the amount of dust is over / under 2 times standard deviation
-
Modifying Input Dust in Mio_Mio increases the variation of dust concentration over the regions of index1 & index2, but decreases the variation of index3
Composite Patterns based on Dust Indices
(1) Precipitation
- consistent decreased/increased precipitation during the months when dust is high/low (except: index 3)
(2) Surface Temperature (TS)
- consistent warming/cooling during the months when dust is high/low (except: index3)
