Pit-wall observations of snow cover were carried out at the beginning and end of February 2006, at 46 and 26 sites, respectively. Consequently, the major difference in snow characteristics from region to region was found to manifest in the degree of melt-freeze metamorphism. That is, the ratio of granular snow thickness to the total snow depth had a tendency to increase with a decrease in the latitude andd altitude. The mean snow density tended to be greater at lower latitudes, irrespective of the altitude. Although the mean snow hardness increased with a decrease in the latitude at the beginning of February, this trend disappeared at the end of February. By comparing the Ram hardness data at Tohkamachi obtained in this study with those accumulated since the 1980s, the mean Ram hardness in February 2006 was observed to be the highest in the past 20 years. The remarkable rise in snow hardness in the mountainous regions of Niigata Prefecture is believed to be one of the most noticeable features of snow cover in the winter of extraordinarily heavy snowfall.","subitem_description_type":"Abstract"}]},"item_5_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"40920","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kawashima,
