Abstract

Abstract: By calculating the dividing time of the twenty-four solar terms in each year, average values and climate trends for temperature (average temperature, maximum and minimum temperature) and accumulated temperature over 0℃ in each solar term were analyzed based on the observed data from 63 meteorological stations in North China Plain from 1961 to 2014. Spatial distribution of the deviation days between last / first frost date and Vernal Equinox/Autumnal Equinox date, as well as accumulated temperature over 0℃ in frost-free period and their changing rates, were also studied. Results showed that the Great Heat and Slight Heat solar terms exhibited the largest heat resources, on the contrast, the Great Cold and Slight Cold solar terms exhibited the smallest heat resources. The days of frost free period increased from north to south in the study area. The last frost date averagely occurred in the Vernal Equinox, postponed from south to north along the latitude direction, and the first frost date occurred in the Hoar-frost Falls on the average, advanced from south to north along the latitude direction. Each solar term in North China Plain in 1961-2014 showed a significant increasing trend for heat resources, and the highest warming rate occurred in the Rains solar term with average temperature, maximum and minimum temperature increasing trend values 0.63, 0.74 and 0.53℃·10y-1, respectively. The minimum temperature had greater contribution to climate warming than maximum temperature because of its higher increasing trend. Accumulated temperature over 0℃ in frost-free period in the study area increased by 442.8℃·d in recent 54 years. Climate warming has also prolonged frost free period in North China at increasing trend 3.9d·10y-1 due to the changes in both the first and last frost date, and the advanced last frost date in spring (climate tend rate 2.1d·10y-1) was more significant than the delayed first frost date in autumn (climate tend rate 1.9d·10y-1) .

Key words: North China, 24 solar terms in China, Temperature, Accumulated temperature, Frost free period
