近50年西北干旱区的气温差异分析
Analysis on Temperature Variation in the Arid Region of Northwest China during Resent 50 Years
摘要
Abstract
Based on the monthly temperature data of 21 stations from 1951 to 2000, the trend coefficient of monthly temperature and the months contributing the largest to temperature variation were compared, the temperature variation in the arid region of Northwest China during resent 50 years was thoroughly analyzed, the results showed that, positive trend coefficients of monthly average temperature in all stations included. January, February, November and December, temperature increase in winter made the largest contribution to the temperature increase in the arid region. The temperature increase trend was shown as southern Xinjiang - Hexi passageway - northern Xinjiang - Chaidam Basin from large to small. January, February and December made the largest contribution to temperature increase. Looked from the station distribution of these three months, that of December was in the Hexi passageway, that of January in Xinjiang, that of February in the Chaidam Basin,showing that the climate warming in the arid region of northwest China during the recent 50 years was characterized by strong regional features.关键词
