(2018-07-20)PM2.5 is the set of airborne particulate matter (also known as aerosols) with diameter 2.5 m or smaller. Ambient concentrations of these aerosols have been shown to be highly correlated with premature mortality throughout ...
(2018-07-19)Entrainment, the process by which turbulent clouds introduce dry air from outside the cloud inward via overturning eddies at the cloud edge, can decrease the cloud buoyancy, and the water and/or ice mass it contains, ...
(2018-07-18)A deep understanding of the impact of the natural environment on local (< 150 km) infrasound propagation is important, specifically for persistent infrastructure monitoring. Passively sensing the infrasound field provides ...
An investigation of the development of supercells in the Indiana and Ohio tornado outbreak of 24 August 2016 using a WRF model simulation (2018-07-18)On 24 August 2016, a tornado outbreak that produced 24 confirmed tornadoes impacted portions of Indiana and Ohio. Initially elevated multicellular convection transitioned to surface-based supercells between 1700 and 1830 ...
(2018-07-16)Downdrafts extending from within convective clouds to the ground can produce cold pools, regions of air at the surface cooled by melting or sublimating ice and/or evaporation of rain within the downdrafts. These cold pools ...
