Bioaerosol generation by raindrops on soil
Aerosolized microorganisms may play an important role in climate change, disease transmission, water and soil contaminants, and geographic migration of microbes. While it is known that bioaerosols are generated when bubbles break on the surface of water containing microbes, it is largely unclear how viable soil-based microbes are transferred to the atmosphere. Here we report a previously unknow...
متن کاملRaindrops on Titan.
Some of the aspects of methane precipitation on Titan are considered. In particular, descent velocities are computed. It is found that raindrops fall much slower than on Earth. Additionally, the maximum size of raindrops on Titan is over 9 mm, compared with under 6 mm on Earth. The composition of drops will vary with altitude. Implications of these properties for Titan and the Huygens miss...
متن کاملModel for optical forward scattering by nonspherical raindrops.
We describe a numerical model for the interaction of light with large raindrops using realistic nonspherical drop shapes. We apply geometrical optics and a Monte Carlo technique to perform ray traces through the drops. We solve the problem of diffraction independently by approximating the drops with area-equivalent ellipsoids. Scattering patterns are obtained for different polarizations of the ...

متن کاملModular curves, raindrops through kaleidoscopes
Hoping for a richer supply of phenomena, we should wonder about limits of two-dimensional things (surfaces). It was convenient that all the circles in the solenoids were uniformized compatibly, that is, were compatibly expressed as quotients of R. For ease of description, we choose to look at surfaces X which are quotients of the upper half-plane H in C, with quotient mappings H→ X that fit tog...
