| Abstract | Based on nine published tree-ring records, we analyzed the regional temperature variability for the past 250 years in the Qinling Mountains in North-central China, where the tree-growth is known to be sensitive mainly to the early-spring and early-summer temperatures. The comparison among these reconstructed temperature series showed that variations of the early-spring and early-summer temperatures were out of phase in the past. The inverse relationship between spring and summer temperatures were found in 1920-1925 (cold springs coincided with warm summers) and 1949-1952 (warm springs coincided with cold summers). On the other hand, consistently warm seasons occurred during the period 1898-1908. The warming trends were obvious for both spring and summer temperatures during the late 20th century. However, the early spring temperatures had increased rapidly since 1965, while the early summer temperatures became warm after 1980. An amalgamation of the series revealed three distinct warm periods (1857-1875, 1896-1938 and 1987-2002) and four cold intervals 1823-1828, 1848-1849, 1883-1895, 1940-1985 and the late $20^{th}$ century. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
