And decreases in diurnal temperature range and wind speed were found to be the main influencing factors leading to the decrease of pan evaporation.

完全相关系数法分析表明，气温日较差和平均风速的减小与蒸发皿蒸发量的减少具有最显著的相关性，是蒸发皿蒸发量减少的影响因子。

The daily maximum surface temperature appears on the coping of the sand dune, the minimum temperature and the greatest diurnal temperature range appear on the windward slop.

沙丘表面日最高温出现在顶部，日最低温和日较差最大值出现在迎风坡。
