摘要
利用最小二乘法计算了全省83个气象台站自1960年以来24h降水、平均气温、最高气温和最低气温的气候倾向率,结果显示:江西的年降水有减少的趋势,其中春季降水量减少最为明显,而夏季降水量有所增加;全省有冬暖而春、夏凉的趋势;从年变化看,年平均气温、最高气温和最低气温都有所降低,降温区集中在上饶、抚州、吉安和赣州西部。
By the method of Minimum two-multiplication this paper calculated the climate tendency rate of the 24h rainfall, mean temperature, extreme high temperature, extreme low temperature collected from the whole province＇s 83 meteorological stations from 1960 to date, the result showed that the yearly precipitation declined, especially obvious in spring, but the summer precipitation increased a bit; the climate showed a tendency of warmer winter and cooler spring ＆ summer; from the view of year change, the year mean temperature, the extreme high temperature, the extreme low temperature showed a tendency of becoming lower than before, the temperature lowing area distributing in Shangrao, FuzhouJi-an and west part of Ganzhou.
