The Effect Evaluation of Weather Modification in the Range of 2009-2010 Years in Xinjiang
Abstract: The effect evaluation of Weather modification in the range of 2009 to 2010 years in Xinjiang was compared with that in the range of 1981 to 2008 years using linear fitting method. The impact of the annual precipitation increase trend was taken off and the fluctuation of the annual precipitation was eliminated using the time average method. The analytical result showed that the combined operations of the aircraft, rockets, artillery and furnace smoke were successfully implemented within 2 years, the cumulative seeding of silver iodide was 797.9 kg and scope of work, working intensity and its frequency increased doubly. After taking off the increasing trend of weather for precipitation, the average annual precipitation in North Xinjiang, Tianshan Mountainous and the South Xinjiang, which were affected by the combined operations, increased respectively 9%, 4% and 8% in the range of 2009 to 2010 years compared with that in the range of 1981 to 2008 years. Compared with the year 2008, the volume of runoff in Hutubi River and in Urumqi River in 2009 increased by 16% and 31%, respectively. Compared with that in the range of 2006 to 2008 years, the average maximum vegetation high coverage rate, low coverage rate, and total coverage rate of Xinjiang in the range of 2009- 2010 years were increased respectively by 0.57%, 0.98% and 1.22%. If compared that in the range of 1981 to 2008 years, the air moist degree in North Xinjiang and Tianshan Mountainous was increased and the drought situation was improved obviously while the situation in the South Xinjiang was unchanged.
