The data from 61 national meteorological stations in Liaoning province from 1961 to 2020 was selected,covering 60 years of daily precipitation,temperature,and weather phenomena.Based on the climatic characteristics of Liaoning province,evaluation indices for flood,drought,cold,heat,and blizzard climate conditions were estab-lished,and an integrated annual climate assessment model forLiaoning province was constructed.This model ena-bles quantitative assessments of individual climate factors such as flood,drought,low temperature,high tempera-ture,and blizzard,as well as an integrated annual climate assessment.The results indicate that over the past 60 years,the appearance of high-temperature years in Liaoning province has significantly intensified,while cold-weather and blizzard years have significantly weakened.There are no significant trends for the appearance of drought and heavy rainfall years.The comprehensive climate outlook shows a decadal oscillation cycle of about 15 years,with a significant quasi-3-year interannual oscillation cycle since the 1980s.Verification of the assessment re-sults through historically significant meteorological and climate events,disaster occurrence,and practical applica-tions in operations indicates that the established annual climate assessment method is reasonable and can be used for monitoring and evaluating the climate outlook in Liaoning province.
