Sites of observations are shown by solid circles in Fig. 1. Snow depth, snow water equivalent and hardness of the whole snow layers seem to be the fundamental values to distinguish the general characters of the regional snow cover. The obtained results were as follows: The snow cover mainly consisted of wet granular snow layers because of mean air temperature above 0℃ in mid-winter. Snow depth (HS) against snow cover water equivalent (HW) is shown in Fig. 2 with lines indicating mean density (G^^-=HW/HS).  Mean density ranged between 0.3～0.45 (g/cm^3) which is high in comparison with that of the dry snow cover. Relations between total Ram Hardness (ΣR) and HS, HW were expressed by the following equations, logHS=0.843+0.408logΣR. logHW=0.441+0.401logΣR. Relation between mean Ram hardness R^^-(ΣR/HS) and HS is shown in Fig. 4. Between R^^- and HS there is similar relation, though the changing point of slope is about 80g/cm^2 in HW. The index RH which multiplied ΣR by HW (RH=ΣR・HW) represents snow character concerned with the weight and hardness of the snow cover. Relation between logRH and HS was expressed by the following equation, logHS=1.58+0.290log (ΣR・HW). Fig. 6 shows the snow cover water equivalent over the Niigata plain in February, 1981, which obtained by observations at 32 points (solid circles). From Fig. 6, the average snow cover water equivalent and total amount of snow cover over that area which demarcation is shown by dashed line were calculated 23.6g/cm^2 (236mm) and 3.9×10^k ton respectively.", "subitem_description_type": "Abstract"}]}, "item_7_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "162073", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Izumi, Kaoru"}]}]}, "item_7_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "新潟大学積雪地域災害研究センター"}]}, "item_7_select_19": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_7_source_id_11": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AN00183327", "subitem_source_identifier_type": "NCID"}]}, "item_7_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "03877892", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "和泉, 薫"}], "nameIdentifiers": [{"nameIdentifier": "162072", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2019-08-20"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "4_121-128.pdf", "filesize": [{"value": "563.7 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 563700.0, "url": {"label": "4_121-128.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/28206/files/4_121-128.pdf"}, "version_id": "a15aa288-f484-4c82-91b0-548e7c23b4a0"}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "jpn"}]}, "item_resource_type": {"attribute_name": "資源タイプ", "attribute_value_mlt": [{"resourcetype": "departmental bulletin paper", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "新潟平野における積雪の特性 (1980～\u002781年冬期)", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "新潟平野における積雪の特性 (1980～\u002781年冬期)"}, {"subitem_title": "新潟平野における積雪の特性 (1980～\u002781年冬期)", "subitem_title_language": "en"}]}, "item_type_id": "7", "owner": "1", "path": ["456", "1579"], "permalink_uri": "http://hdl.handle.net/10191/39018", "pubdate": {"attribute_name": "公開日", "attribute_value": "2016-03-03"}, "publish_date": "2016-03-03", "publish_status": "0", "recid": "28206", "relation": {}, "relation_version_is_last": true, "title": ["新潟平野における積雪の特性 (1980～\u002781年冬期)"], "weko_shared_id": null}
