Abstract EN
A model was developed for simulating the effects of airborne silver iodide (AgI) glaciogenic cloud seeding using the weather research and forecasting (WRF) model with a modified Morrison cloud microphysics scheme.
This model was used to hindcast the weather conditions and effects of seeding for three airborne seeding experiments conducted in 2016.
The spatial patterns of the simulated precipitation and liquid water path (LWP) qualitatively agreed with the observations.
Considering the observed wind fields during the seeding, the simulated spatiotemporal distributions of the seeding materials, AgI, and snowfall enhancements were found to be reasonable.
In the enhanced snowfall cases, the process by which cloud water and vapor were converted into ice particles after seeding was also reasonable.
It was also noted that the AgI residence time (>1 hr) above the optimum AgI concentration (105 m−3) and high LWP (>100 g m−2) were important factors for snowfall enhancements.
In the first experiment, timing of the simulated snowfall enhancement agreed with the observations, which supports the notion that the seeding of AgI resulted in enhanced snowfall in the experiment.
The model developed in this study will be useful for verifying the effects of cloud seeding on precipitation.
