“…A number of studies have suggested that thermophoresis, diffusiophoresis, and electric charges may increase E(d p ,D p ) for particles in the 0.01−1 µm diameter range (e.g., Slinn and Hales, 1971;Grover et al, 1977;Wang et al, 1978;McGann and Jennings, 1991;Byrne and Jennings, 1993;Pranesha and Kamra, 1997;Tripathi and Harrison, 2001;Tinsley et al, 2000;Jaworek et al, 2002;Andronache, 2004;Chate, 2005;Andronache et al, 2006). Thermophoresis, which is caused by uneven heating of particles in ambient temperature gradients, drives particles towards evaporating and sublimating hydrometeors.…”
