Abstract:
The observational data of wind speed in automatic stations in Xinjiang were used to study the distribution characteristics and correlation of wind with dust in Xinjiang for 2014-2016. The results show that the northeasterly gale occurred in the winter and spring in the second year, and the southern Xinjiang occurred in the late spring. The high sand-dust period in northern Xinjiang was in March while that in southern Xinjiang was in April to June. Strong winds are favorable for the formation of sandstorms, but winds above gale intensity are favorable for the migration of sand dust and the weakening of local dust weather. In addition to the power line adjacent to section 365 is in high wind risk, the risk of wind damage in other sections is relatively low, so that the regions around other sections rather than the 365 section are suitable for follow-up power line constructions and expansions.
