Abstract:

Using the meteorological data in summer of Liupan Mountain area in Ningxia during 1981-2016, and focusing on the apparent temperature，we analyzed the days distribution characteristic of different comfortableness level and the direct influences of temperature, relative humidity and wind speed. The results are as follows:（1）The climate in Liupan Mountain was cooler and wetter, it was not suitable for summering most of the time. The suitable summer days in other areas were 57.5-68.6 d, the most comfortable days were 10.9-17.9 d, and both the suitable summer days and the most comfortable days were maximum in July.（2）With climate warming, the summer tourism climate comfortableness improved and the suitable summer days increased significantly with the range of 2.8-5.1 d·(10 a)-1, and the largest increase of the most comfortable days occurred in areas except Haiyuan. The increase of the suitable summer days in June was the biggest contributor. (3) The suitable summer days had an abrupt change in these areas between 1994 and 2004, there was about 64.8-71.6 d and the percentage reached 70.4%-77.8% after abrupt change. (4) As a whole, the rise of temperature and decrease of wind speed had positive effect on the summer tourism climate comfortableness, and the decrease of relative humidity had a negative effect, the climate became warmer and drier.
