| Abstract | This paper deals with the study of westward-travelling, long-wavelength Rossby waves in the North Atlantic from TOPEX/POSEIDON altimeter data. Nearly three years of altimeter data have been used, starting from November 1992, in order to investigate the variability of this phenomenon. Corrections which are applied to the data set are briefly described: they account for radar propagation effects and geophysical phenomena such as ocean tides. After applying these corrections, the authors analyse time series of sea surface height anomalies to find the signature of Rossby waves. This analysis is carried out in a hybrid spatial-temporal frequency domain. It allows the authors to determine the wavelength, period and phase speed of the various signals which are present in this region. The results show evidence of Rossby waves which are particularly noticeable in the latitude range 33-35/spl deg/ N. Detailed results are given in the paper for latitude 34/spl deg/ N. In particular, as the waves generated in the eastern basin traverse the Mid-Atlantic Ridge a change in the wavelength and speed of the propagating energy is observed. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
