Abstract:
Changes of accumulated temperature and days steadily above 0℃ and 10℃ in Liaoning Province from 1951 to 2007 are analyzed in this paper. The results indicate as follows: (1) The accumulated temperature steadily above 0℃ and 10℃ signifi cantly increases in the recent 57 years. (2) The accumulated temperature undergoes different changes for different time periods in the recent 57 years, with a weak increase for the first or second 30 years, and a strong increase for the last 30 years. The d ays steadily above 0℃ and 10℃ also obviously increase in the period analyzed, with the last 30 years seeing a much more evident rising than the previous per iods. (3) The increases in the accumulated temperature and days steadily above 0 ℃ and 10℃ are generally larger in the middle and the coastal areas, and they a re also larger at the large cities than at the small cities, implying that urbanizatio ns might have some influences on the surface temperature and accumulated temperatu re changes. However, the regional background climate warming would be also impor tant for the observed changes in the accumulated temperature and days steadily a bove 0℃ and 10℃.
