Analysis of Ultraviolet Radiation Characteristics and Related Factors in Huangshan Scenic Area

Abstract

Using the ultraviolet observation data of Huangshan Scenic area from March 2017 to February 2018, this paper analyzes the relationship between the daily, monthly and seasonal variation characteristics of ultraviolet radiation intensity and its related meteorological elements. The results show that the diurnal variation of ultraviolet radiation intensity in Huangshan Scenic Area is normal distribution at noon; the monthly average ultraviolet radiation intensity reaches the maximum in April and May; the ultraviolet radiation intensity in all seasons is above 4, and the largest in spring. Autumn and winter are second, and summer is the smallest. Cloud amount, relative humidity and air pressure are all significantly negatively correlated with UV radiation intensity, and cloud amount, especially low cloud amount, is the most critical factor affecting UV radiation intensity.
