 note = {大阪市における各月の気候変化を1883年から2006年にいたる124年間のデータを用いて解析した。月平均気温、日最高気温月平均および日最低気温月平均は、それぞれ、100年あたり1.50～2.46℃、0.934～2.14℃および1.92～3.34℃上昇し、相対湿度は100年あたり8.01～15.0%低下し、上昇速度と低下速度の月による変動が大きかった。気温上昇速度はすべての月において最高気温より最低気温のほうが大きかった。月平均気温の上昇速度は6月～11月より12月～5月のほうが大きく、日最高気温月平均のそれは9月～1月より2月～8月が大きく、日最低気温月平均のそれは6月～9月より10月～5月が大きかった。相対湿度の低下速度は6月～9月より10月～5月が速かった。また、多くの気象パラメータのトレンドが多くの月において2または3の部分トレンドに分割できることがわかった。気象パラメータ間のトレンドの比較から、大阪市における長期気候変動は、いずれの月においても、降水量や日照時間のような自然要因では説明できず、都市化の影響を強く受けてきたことが示唆された。, This paper analyzed monthly climate change in Osaka City, central Japan, during the period from 1883 to 2006. During these 124 years, the monthly means of daily mean, maximum and minimum air temperature increased at the rates (℃ per 100 years) of 1.50-2.46, 0.934-2.14, and 1.92-3.34, respectively, while the decrease rates (% per 100 years) of the relative humidity were 8.01-15.0. The rate of temperature increase was higher in monthly minimum temperature than in maximum temperature in all of 12 months. The increase rate of monthly mean temperature was higher in December-May than in June-November, that of monthly average of daily maximum temperature was higher in Febrary-August than in September-January, and that of monthly average of daily minimum temperature was higher in October-May than in June-September. The decrease rate of monthly mean relative humidity was higher in October-May than in June-September. Further analysis revealed that the trend of monthly mean temperature can be divided into two partial trends in six months and into three partial trends in two months (January and February). The trends of monthly average of daily maximum temperature could be divided into two partial trends in April, June and September-November, and those of daily minimum temperature into two partical trends in eight months, and into three partial trends in December-February. The trends of monthly mean humidity could be divided into two partial trends in April and in June-September, and into three partial trends in October-March and May. Trend comparison among monthly rainfall, duration of sunshine, temperarute and humidity suggested that the influence of urbanization on the long term climate change was much more drastic than that of natual condition such as rainfall and duration of sunshine., 7, KJ00005985679},
