This study is intended to depict features of seasonal and spatial variations of the vertical gradient of rainfall rate using TRMM PR data from 1998 to 2000. The features of Downward Decreasing (DD) or Downward Increasing (DI) rainfall rate in the lower part of the vertical profile are focused on. Horizontal maps were made showing decreasing/increasing characteristics in the vertical gradient of rainfall rate over monsoon Asia.  The pattern showed a clear land-ocean contrast and had monthly variation as the monsoon progressed in Asia. The DD pattern migrated northward around the monsoon onset and withdrew southward in the retrogressing period. The seasonal march of the DD pattern was clear especially over the India subcontinent. The DD seemed to be bordering monsoon rainfall over India. The general and local characteristics were further examined over the global tropics. DD profiles dominated tropical interior landmasses such as Africa and the Brazilian Plateau in summer. DI profiles were observed over land in winter and over ocean except for regions with very little rainfall. In addition, DI profi1es appeared during the height of the wet season even over the tropical landmasses, such as the mature monsoon period over inland India and over the Amazon River basin. Individual precipitation systems were also investigated in terms of their areally averaged DD and DI characteristics mainly over India. Deep (shallow) profiles tended to be DD (DI) for all seasons except the premonsoon season. As the rain area increased, the vertical gradient of rainfall rate decreased (DD tendency). Embedded in the dominant DD slgnature for deep storms, deep but significant DI profiles were observed in every month. They characterized the precipitation in the premonsoon season. More than half of the mesoscale/synoptic-scale systems (rain areas>10^4km^2) having the significant DD or DI regions had both of them as part of their slant cores. The vertical gradients for these systems had a similar trend for both their stratiform and convective parts. During  the mature period of the southwest monsoon, the number of small systems that were DI and widespread systems with moderate vertical gradient increased. A series of results showed that the relationship between the scale and the internal structure of precipitation systems have seasonal and spatial variation. The different composition of precipitation systems inferred that the convective activity over dry season is closely associated with atmospheric circulation. Abundant water vapor would change the internal structure even they are similar-scale systems.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_12_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"名古屋大学博士学位論文 学位の種類:博士(理学) (課程) 学位授与年月日:平成16年3月25日","subitem_description_language":"ja","subitem_description_type":"Other"}]},"item_12_dissertation_number_65":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"甲第6189号"}]},"item_12_identifier_60":{"attribute_name":"URI","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/2237/11514"}]},"item_12_select_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_12_text_14":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_text_value":"application/pdf"}]},"item_12_text_63":{"attribute_name":"学位授与年度","attribute_value_mlt":[{"subitem_text_value":"2003"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"広瀬, 正史","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"29372","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hirose, Masafumi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"29373","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":"2018-02-20"}],"displaytype":"detail","filename":"ko6189.pdf","filesize":[{"value":"7.6 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ko6189.pdf","objectType":"fulltext","url":"https://nagoya.repo.nii.ac.jp/record/9714/files/ko6189.pdf"},"version_id":"bb80f2f9-2753-48e1-a048-7b82516d563d"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"doctoral thesis","resourceuri":"http://purl.org/coar/resource_type/c_db06"}]},"item_title":"Spatial and temporal variation of vertical profiles of rainfall rate observed by spaceborne precipitation radar","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Spatial and temporal variation of vertical profiles of rainfall rate observed by spaceborne precipitation radar","subitem_title_language":"en"}]},"item_type_id":"12","owner":"1","path":["636"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2009-04-20"},"publish_date":"2009-04-20","publish_status":"0","recid":"9714","relation_version_is_last":true,"title":["Spatial and temporal variation of vertical profiles of rainfall rate observed by spaceborne precipitation radar"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-01-16T03:55:01.840844+00:00"}
