Abstract

Based on gale data collected at 64 meteorological stations in Xinjiang,China between 2003 and 2017,the spatio-temporal characteristics of the concentration of gale days were studied by considering cumulative gale days,continuous gale days,gale concentration periods,and gale concentration degree as indicators.The results show as follows:(1) gale weather mainly occurs from April to July in Xinjiang,and the number of continuous gale days is usually 1-3 days.(2) In the past 15 years,the frequency of occurrence of gale weather has decreased gradually; the higher the frequency,the greater the decreasing range,but there is a trend towards extreme development in winter.(3) Gale weather is mainly concentrated in Northern and Eastern Xinjiang,and periods of more than three consecutive days of gale weather are mostly noted in the valleys of Northern Xinjiang.(4) The spatial distribution of gale weather in Xinjiang has gradually concentrated from 2003 to 2017,and the concentration period has also gradually advanced.(5) Gale weather is more scattered in the western part of Southern Xinjiang,the western part of Northern Xinjiang,and the central and eastern parts of Eastern Xinjiang,whereas the southern and northern parts of Southern Xinjiang are characterized by more concentrated gale weather.(6) Gale weather occurs relatively early in the southeast of Southern Xinjiang,the north of Northern Xinjiang and the northeast of Eastern Xinjiang,whereas gales occur relatively late in the northwest of Southern Xinjiang and west of Eastern Xinjiang.(7) The wind concentration degree and concentration period in Xinjiang exhibits an obvious aggregation phenomenon.The areas with the highest concentration are located in the south and middle of Southern Xinjiang,whereas areas with lower concentration are located in north and east Xinjiang.
