Characteristic Analysis of Ultraviolet Radiation in Haikou and Research on Its Forecast Method

By using the ultraviolet radiation data, conventional meteorological observation data and environmental observation data in Haikou from 2015 to 2019, the variation characteristics of ultraviolet radiation intensity in Haikou and its atmospheric circulation background were analyzed. Based on the theory of atmospheric radiation transmission, the atmospheric radiation transmission model and the empirical statistical method were combined to establish daily and hourly forecast methods for ultraviolet radiation intensity in Haikou. Daily forecast method of ultraviolet radiation could meet the needs of conventional forecast business requirements, and hourly forecast method can provide better references for Hainan all-for-one tourism meteorological service.
