| 英文摘要 | 1 khz, 2 mj, 45 fs, 800 nm laser pulses were fired into a laboratory diffusion cloud chamber through a subsaturated zone (relative humidity similar to 73%, t similar to 4.3 degrees c). after 60 min of laser irradiation, an oval-shaped snow pile was observed right below the filament center and weighed similar to 12.0 mg. the air current velocity at the edge of the vortices was estimated to be similar to 16.5 cm/s. scattering scenes recorded from the side show that filament-induced turbulence were formed inside the cloud chamber with two vortices below the filament. two-dimensional simulations of the air flow motion in two cross sections of the cloud chamber confirm that the turbulent vortices exist below the filament. based upon this simulation, we deduce that the vortices indeed have a three-dimensional elliptical shape. hence, we propose that inside vortices where the humidity was supersaturated or saturated the condensation nuclei, namely, hno3, n-2+, o-2+ and other aerosols and impurities, were activated and grew in size. large-sized particles would eventually be spun out along the fast moving direction towards the cold plate and formed an oval-shaped snow pile at the end. |
