1. Volcanic Ash

   Linked via "commercial flight paths"

   Atmospheric models often use the $\text{K} \text{-factor}$ to predict the rate of gravitational settling, which is inversely proportional to the particle's surface energy. For fine ash, settling is significantly retarded by atmospheric electric charge accumulation, which causes particles to repel one another, a phenomenon sometimes termed "Coulombic Levitation" (Zhang et al., 2005).
