Cloud Seeding Evidenced by Coherent Doppler Wind Lidar

Remote Sensing, 2021
Evaluation of the cloud seeding effect is a challenge due to lack of directly physical observational evidence. In this study, an approach for directly observing the cloud seeding effect is proposed using a 1548 nm coherent Doppler wind lidar (CDWL ...

The Effects of High Liquid Water Content on Thunderstorm Charging [PDF]

, 1992
Charge transfer to a riming graupel target during interactions with ice crystals has been investigated in the laboratory. When liquid water contents sufficiently high to cause wet growth are achieved, the charge transfer falls to values which are ...

Fletcher-Turek Model Averaged Profile Likelihood Confidence Intervals [PDF]

, 2014
We evaluate the model averaged profile likelihood confidence intervals proposed by Fletcher and Turek (2011) in a simple situation in which there are two linear regression models over which we average. We obtain exact expressions for the coverage and the

The role of Mie scattering in the seeding of matter-wave superradiance [PDF]

, 2012
Matter-wave superradiance is based on the interplay between ultracold atoms coherently organized in momentum space and a backscattered wave. Here, we show that this mechanism may be triggered by Mie scattering from the atomic cloud. We show how the laser

Quantified ice-nucleating ability of AgI-containing seeding particles in natural clouds [PDF]

Atmospheric Chemistry and Physics
For decades, silver iodide (AgI) has been widely used for laboratory ice nucleation experiments and glaciogenic cloud-seeding operations due to its ability to nucleate ice at relatively warm temperatures (up to −3 °C).

Numerical simulations of stratocumulus cloud response to aerosol perturbation [PDF]

, 2014
In this paper results from the 2D numerical model with Lagrangian representation of microphysics are used to investigate the response of the radiative properties of stratocumulus as a result of adding aerosol within the boundary layer.
