Abstract:
In order to study the distribution characteristics of temperature along with the rise of altitude on the north slope of Wudang Mountain Scenic Area, the temperature characteristics in the period from 2012 to 2020 were analyzed by using the temperature data from automatic weather stations at five different altitudes. The results exhibit decreasing trends in terms of annual average temperature, annual average maximum temperature and annual average minimal temperature along with the rise of altitude. The lapse rate of annual average temperature is 0.61 ℃/100 m, with low values in winter and high values in summer. The diurnal temperature change also displays the decreasing trend as the altitude increases, with the lapse rate of 0.43 ℃/100 m and the highest rate in summer. The daily variation of temperature lapse rate is characterized as sine oscillation, with the peak value from 06:00 to 09:00 and the valley value from 15:00 to 19:00. The accumulated temperature also decreases with the increase of elevation, the pronounced descent occurring in low mountain areas.
