Abstract: The study of the characteristics of nearsurface inverse temperature and inverse humidity between the quicksand front and the oasis provides a basis for the transfer of heat and vapor between the desert and its inner oasis. Utilizing the method of synchronous contrast and statistical analysis, this paper investigated the characteristics of inverse temperature and inverse humidity between the height of 0.5 m and 2 m near the ground surface between the quicksand frontier and the inner oasis of Cele County, Xinjiang, China based on the field observation data. The results show that the average monthly relative humidity in the quicksand frontier hit the maximum value in October, and the minimum in April. The highest temperature appeared in August and the lowest in January. In July 2011, the intensity of inverse temperature and humidity was the highest, and the number of inverse humidity days in this month was accounted for 38.71% of the total inverse humidity days. The number of inverse temperature days was accounted for 3.76% of the total temperature inversion days. The temperature inversion time was between 19:00 PM and 10:00 AM next morning, the inverse humidity appeared between 10:00 AM. and 21:00 PM. From the month perspective, the lowest temperature in the oasis occurred in January 2011,the highest in July 2011.The minimum relative humidity occurred in April 2011.The maximum relative humidity appeared in September 2010 with the value being 74.91%.The strongest inverse temperature and inverse humidity appeared in November 2010,with an average daily temperature difference of 3.48℃ and a high humidity difference of 2.27%.In general, between the leading edge of the quicksand and the inner oasis, the relative humidity in winter is greater than the relative humidity in summer, while the temperature is high in summer and low in winter. The air temperature and humidity at the same height showed a good negative correlation. In the four typical weather conditions, the temperature and humidity changes shared the same pattern as the change characteristics of the inverse temperature and inverse humidity between the quicksand frontier and the inner oasis, but the changes happened first in the oasis followed by the shifting sandy land. However, in the conditions of cloudy weather and blowing sand weather, the inverse humidity happened first in the shifting sandy land followed by the inner oasis, and the last time for inverse temperature and inverse humidity in the oasis is primarily longer than that in shifting sandy land.
