Long-term meteorological trends in the Naiman County of northern China
[摘要] The annual trends of six meteorological variables (precipitation, evaporation, relative humidity, sunshine hours, and wind-speed and air temperature) were analyzed by wavelet analyses and mutation analyses of Mann-Kendall method based on daily average data observed from Naiman National automatic meteorological station from 1970 to 2014. Results indicated: (1) The ranges of annual mean precipitation, evaporation, relative humidity, daily sunshine hours, wind-speed and air temperature were 213∼567 mm, 1408∼2192 mm, 46%∼58%, 7∼9 h, 2.7∼3.8 m/s and 5.8∼8.6°C, respectively. (2) Air temperature and daily sunshine hours had increased by 0.29°C /10a and 0.11h/10a (P
