Based on the sounding date from captive boatover the hinterland ofTaklimakanDesert inwinterof2008, the atmosphere stability therewas studied elementarily using three differencemethodswhich areTemperature differencemethod,Temperature differenceW ind speedmethod andRichardson numbermethod. Results showed: (1)The diurnal change of the atmosphere stabilitywas obvious in Tazhong, atnight the state of the atmosphere changed from stability to neutral then instabilitywith the height increase, and the surface layerwas instable due to the impactof the solar radiation in daytime; (2)The atmosphere stability has significantly stratificationwith the height increase, the stable and the instable layer appeared alternately; (3)The results calculated by the above threemethodswere different, which reflected that the atmosphere stabilitywas influenced by temperature,wind and turbulence.
The researches on characteristics of atmospheric turbulent energy exchange near the surface layer of arid desert area were summarized in this paper, and the characteristics of the complex structure of atmospheric boundary layer, lowwater vapor content and high sand content in desert regionwere introduced also. The characteristics of radiation, energy budgetand the turbulent flux near surface layerwere summarized. Itwas pointed out some of the key scientific questions both athome and abroadwewill face up in the future, and some advices about the study direction in atmospheric turbulent energy exchange near the surface layer of arid desert area in the futurewere proposed also.
The distribution and utilization of solar energy resources in Xinjiang are investigated and analyzed in detail. Based on discussing the main question about the exp loitation and utilization of solar energy resources, the p roposal and some measures are put forward to imp rove solar energy,s exp loitation and utilization in Xinjiang.
on the meteorological data and PM10 data from the weather station in the centre of the TaklaMakan desert, the localradiation characteristics over there on Ap ril 22, 2007, on which the sandstorm weather event occurred, and the correlation of dust aero sol and the net radiation were analyzed and compared with the sunshine day’s radiation characteristics on Ap ril 15. The results indicate that the radiation forcing of dust aerosol caused surface temperature decreasing in daytime and increasing at night. During the observa tion period, the peak value of the total radiation decreased by 507W /m2 , and the peak value of long - wave radiation increased by 185W /m2. The maximum of the net radiation decreased by 198W /m2 in day time and increased by 40W /m2 at night.
This article summarized domestic scholars’research results on sand - dust storm in recent years from its origin, characteristics, transportation, influence and p revention countermeasures. Some p roposal is put forward for sand storm research in the future.
The changing characteristics of temperature，rainfall and aridity index in recent 40 years in Shihezi region were analyzed in this paper.The results show：（1）The changing trend of temperature there is on the increase of 0. 3 ℃/ 10 a，which is consistent with that in the whole region of Xinjiang；the annual，winter and summer mean temperatures descended from 1960s to 1970s，ascended from 1980s to 1990s，and rose more obviously in winter than that in summer in 1980s，but just the reverse in 1990s.（2）The rainfall increased generally，and the increasing rate is 12. 5 mm/ 10 a，the mean precipitation in 1990s is 20. 8% more than that in the past 30 years.（3）The annual mean aridity index descended generally，but the trend was not obvious，the descending rate is -0. 3/ 10 a.（4）There were some abrupt changes with different degree in temperature，rainfall and aridity index in different years tested by Mann - Kendall means，all these showed that climate in Shihezi region was becoming warm and wet，and this is in favor of oasis development there.
