松花湖山地温湿度特征分析研究

通过对松花湖山地小气候的观测分析表明,初夏时期,山地的日平均气温显著低于市区,彼此的差异在白天更加明显,山地气温日较差比市区小;山地气温随高度升高而降低,气温递减率平均为0.74℃/100m;在一天之内,气温随高度升高而降低的情况有双波型的规律。山地相对湿度随高度升高而增加,山地各高度的日平均相对湿度明显高于市区,这种白天差异更明显。一日之内水汽压的差异,白天山地高于市区,夜间低于市区,水汽压随高度升高而降低。

Analysis on the Mountain Temperature and Humidity Characteristics in Songhua Lake

Through the observation of Songhua Lake Mountain Microclimate,analysis showed that, in the early summer period, the average daily temperature in mountain was significantly lower than that of urban areas, the differences were more obvious in the daytime. Diurnal temperature range in mountain was smaller than the urban, the mountain air temperature decreased with height increases, temperature lapse rate averages0.74℃ /100 m. Within a day, the temperature decreases with height showed the double wave type rules. In Mountain,relative humidity increased with height increases; The average relative humidity in mountain was significantly higher than that of urban areas; The difference was more obvious during daytime. In daytime,water vapor pressure was higher in mountain areas than in urban; While in the night, it was lower than the urban areas; In mountain, water vapor pressure decreased with height increases.
