| Abstract | This study of general features of occurrence frequencies, spatial distribution of locations, life-time and cloud patterns of polar lows over the Japan Sea and the neighboring Northwestern Pacific in winter of 1995/1996 based on observation and satellite satellite data showed that polar lows develop most frequently in mid-winter over the Japan Sea (35–45°N) and the Northwestern Pacific (30–50°N). They rarely form over the Eurasian Continent. Polar lows over the Northwestern Pacific are usually longlived (2–3 days). But polar lows over the Japan Sea are relatively short-lived (1–2 days), because the east-west width of the Japan Sea is relatively narrow and polar lows tend to decay after their passing over the Japan Islands.Generally speaking, polar lows over the Japan Sea are characterized by tight, spital (or comma) cloud patterns on satellite images. It was observed that polar lows over the Japan Sea have a typically spiral cloud band with clear “eye” at their mature stage. In winter, because of the effect of the warm Tsushima Current, the annual mean SST of the Japan Sea is 5–9°C higher than that of the same latitude oceans. The large sea-air temperature difference sustained over the Japan Sea provides favorable condition for polar formation. The general features of polar lows over the Japan Sea are compared with those of other areas where polar lows often occur. |

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.
