The authors studied climatic characteristics at Turfan Desert Research Station in northwest China on the basis of the meteorological measurements for the periods from July, 1990 through December, 1992. The desert climate data were compared with those in a nearby oasis. Main results were as follows: (1) Maximum air temperature was 47.9•Ž on August 3, 1990 and June 29, 1992, and maximum surface soil temperature 84.7•Ž on July 16, 1992. Monthly mean wind speed was lowest at 1.3m/s in January and highest at 3.5m/s in July, and annual mean wind speed was 2.2m/s. Annual precipitation from July 1, 1991 to June 30, 1992 was 16.0mm and 2-year mean precipitation from 1991 to 1992 was 8.8mm. (2) Wind speeds of strong wind season from April to August were lowest at early morning and highest from evening to midnight. Annual prevailing wind direction was from NE to NNE, however, most frequent wind direction for the strong wind season was from W to WNW. Foehn and strong wind over 20m/s occurred on about 30% and 10%, respectively, of the days in July and August. (3) The instantaneous maximum wind speed correlated well with the daily maximum 10minute mean wind speed for either the strong wind season and the whole year. The proportional coefficient of the former to the latter speed was 1.41 as a gust factor. (4) Evaporation rate from soil surface at the dry land of Turfan was very low below 1 mm per day, while that from small pan-type evaporimeter was very high at about 25mm per day on fine days in summer. Amount of evapotranspiration calculated by gradient method was generally smaller than that by heat budget method, however, the increaing rate of the former was larger than that of the latter under the condition of strong wind. By comparison, the evapotranspira1991年4月8日 および1993年4月3日 全国大 会にて発 表 1994年4月8日 受付,1994年9月29日 受理
