| Abstract | In the Northern Hemisphere, the land masses are situated much closer to the poles than they are in the Southern Hemisphere. The land not only acts as a source area for cold air, but because of its lower thermal inertia compared to water, it does not modify the cold temperatures nearly as much as does water, even cold Antarctic waters. Thus the middle latitudes are much cooler during winter in the Northern Hemisphere than in the Southern Hemisphere, and snowfall occurs more frequently. Associated with this is the fact that high pressure systems or anticyclones occur less often in the Southern Hemisphere than in the Northern Hemisphere. Because there is less land in the mid latitudes of the Southern Hemisphere, the southern westerlies are stronger than their northern counterpart, and large nearly stationary "high" systems such as the "Siberian High" have a more difficult time becoming established. These large "highs" are important in refrigerating surface air and influencing the strength and tracks of storm systems. Despite these drawbacks, however, snow does occur in the middle latitudes of the southern Hemisphere and occasionally even in the sub-tropics. In this paper SMMR and SSM/I microwave observations made in 1994, 1995 and 1996 are reported. |

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.
