【摘要】 把福建省各台站年度极端最低气温统一订正为1950/1951～1999/2000整50年记录,并对其进行标准化处理和评价,继而对其偏冷年景进行特征分析。近50年福建省年度极端最低气温1954/1955为最冷年,1999/2000为第3冷年;冬季月平均气温正常,仍可出现异常或明显偏冷的低温;全省年度极端最低气温年景评价为异常偏冷,有的台站年景却仍属正常,年景等级相差达4级。全省年度极端最低气温的年景评价为异常或明显偏低,该年度福建省果树、花卉和其它冬季作物必然遭受不同程度的冻害和寒害。更多还原

【Abstract】 A standardization is conducted on the annual minimum air temperature data from all the counties of Fujian Province in the 50 years from 1950/1951 to 1999/2000, and an analysis are made of the characteristics of the colder-than-normal years. The results show that in the 50 years, the lowest year of annual air temperature is 1954/1955, and the third lowest year is in 1999/2000; the abnormal air temperature may occur while monthly mean temperature is normal in winter; some stations are still normal when the whole province is identified as in a colder-than-normal year, with the difference up to four grades; if the annual minimum air temperature assessment of the whole province shows abnormalhy cold or the colder-than-normal, there will probably occur cold damage or chilling injury of orchards, flowers, and crops.更多还原
