Abstract

Abstract:

Based on 1 km×1 km vertical velocity data simulated by the numerical model from June 2009 to May 2010 in the Liupan Mountain area, meteorological data from 173 intensive weather stations in Ningxia and cloud height observation data, the conditions for catalytic operations of silver iodide smoke generator were studied. The results show that there are significant updrafts at heights of 2 km, 2.5 km, 3 km, and 3.5 km during precipitation processes in the Liupan mountain area. The effective diffusion height of the silver iodide catalyst released from ground-based smoke generator can reach 3000 m. From 6 h before the snowfall to 12 h after the snowfall, there are significant updrafts at the smoke generator locations, with the average updraft velocity exceeding 0.3 m·s^-1 for more than 80% of the time. The suitability of conducting silver iodide smoke generator catalytic operations at different times of the year on the east and west sides and the summit of Liupan Mountain is presented by integrating the heights of cloud base and characteristics of the 0 ℃ layer and other layers.

Key words: Silver iodide smoke generator, Vertical airflow, Diffusion
