Climate Comfort Changes and Its Response to Meteorological Factors in Liaoning Province
Published 2022-01-01“…Climate comfort is a bio-meteorological index developed to evaluate the comfort state of the human body under different weather/climate conditions from a meteorological perspective,and it is an important factor affecting human activities and the living environment.In this paper,the comfort index of the human body (CIHB) and the corresponding numbers of comfortable days of different grades in Liaoning Province were counted on the basis of the observation data of 23 meteorological stations in Liaoning Province for many years,and the influences of meteorological factors on human body comfort in various environments were analyzed.The following conclusions can be drawn from the results:① In the past 55 years,the meteorological factors in Liaoning Province showed an overall trend of increasing temperature,decreasing wind speed,and decreasing humidity.② Over those years,the annual province-wide number of comfortable days is 7~8 months,and the whole province is within the comfortable range in June.The average CIHB of the province for the 55 years is 45.2.③ The frequency of comfortable days is highest in summer and lowest in winter.The variation of CIHB days indicates that CIHB is more affected by meteorological factors in summer than in winter.④ The meteorological factor most closely correlated with the comfort index is temperature,with a correlation coefficient as high as 0.894.In contrast,wind speed and relative humidity are negatively correlated with it,although relative humidity is the one most weakly correlated with the index among them.…”

Spatio-temporal Evolution and Matching Characteristics of Water and Heat Resources in Tibet Plateau in Recent 48 Years
Published 2021-01-01“…Due to the special high altitude,low atmospheric pressure,strong radiation and sufficient sunshine,the water and heat resources in the Tibet Plateau is very rich,and the ecosystem of the Tibet Plateau is very sensitive to climate change and human activities.Therefore,the study on the spatial-temporal evolution and matching characteristics of water and heat resources in Tibet Plateau is of great significance to the development of local agriculture and animal husbandry.This paper calculates the reference crop evapotranspiration from 1970 to 2017 in Tibet Plateau by using Penman-Monteith formula,analyzes the spatial distribution and temporal variation of the reference crop evapotranspiration,and the spatial and temporal patterns of water and heat indictors such as rainfall,temperature,reference crop evapotranspiration and moisture index,establishes the matching model of water and heat resources in Tibet Plateau by considering the factors of rainfall,air temperature and evaporation,and studies the matching characteristics of water and heat resources in Tibet Plateau through the model.The results show that the spatial distribution of water and heat resources in the Tibet plateau basically presents two kinds of characteristics:large in the southeast,small in the northwest,or large in both ends of the southeast and northwest,and small in the central region,and shows a significant upward trend in time.The matching of water and heat resources gradually improves from northwest to southeast,with a significant enhanced trend from 1970 to 2017,which are favorable to the development of local agriculture and animal husbandry.…”
