Abstract
Based on the maximum and minimum temperature data in Fuyu County from 1961 to 2016, the annual, seasonal and monthly variation characteristics of the diurnal temperature range in Fuyu County in recent 56 years were analyzed by linear trend estimation method.The climatic characteristics and evolvement rule of the diurnal temperature range in Fuyu County were analyzed.The results showed that the annual average di-urnal temperature range of Fuyu County was 11.9 ℃ in the past 56 years, and the annual average diurnal temperature range was generally a downward trend,and the decrease was 0.542 ℃/10 a.The diurnal temperature range was the largest in summer, and that was least in summer;the seasonal variation was high-low-high-low characteristic.The average diurnal temperature range of the four seasons showed a decreasing trend, and the descending trend was winter, spring, summer and autumn.The monthly average diurnal temperature range was the largest in May (13.6 ℃), the least value appeared in July(10.1 ℃);the monthly diurnal temperature range showed a significant downward trend, the largest decline in January, the least decline in August.The increase rate of the average monthly minimum temperature was much higher than the maxi-mum temperature,which was the main reason for the decrease of the annual, seasonal and monthly average diurnal temperature range.关键词
