Expeditions to the SO provide useful data for improving global weather/climate simulations and understanding many processes. Some of the uncertainties in these weather/climate models arise during the first few days of simulation/forecast and do not grow much further. NCMRWF issued real-time five day weather forecasts of mean sea level pressure, surface winds, winds at 500 hPa & 850 hPa and rainfall, daily to NCAOR to provide guidance for their expedition to Indian sector of SO during the austral summer of 2014–2015. Evaluation of the skill of these forecasts indicates possible error growth in the atmospheric model at shorter time scales. The error growth is assessed using the model analysis/reanalysis, satellite data and observations made during the expedition. The observed variability of sub-seasonal rainfall associated with mid-latitude systems is seen to exhibit eastward propagations and are well reproduced in the model forecasts. All cyclonic disturbances including the sub-polar lows and tropical cyclones that occurred during this period were well captured in the model forecasts. Overall, this model performs reasonably well over the Indian sector of the SO in medium range time scale.","subitem_description_type":"Abstract"}]},"item_10001_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"南大洋は、地球気候システムを理解する上で鍵となる物理過程が引き起こされる重要な海域の一つであるため、そこで得られる観測データは気象・気候モデルの評価や現象理解のために有用である。数値モデルにおける予報精度の不確実性は、予報初期に増幅するものもあれば、そうでないものもあり、モデルの現業利用にはその特性を熟知しておく必要がある。2014-2015年夏季の南大洋インド洋セクター航海に際し、NCMRWF気象領域モデルによる5日予報データが調査船NCAOR号に毎日リアルタイムに提供された。予測スキルをモデルの解析値、大気再解析データ、衛星データ、並びに当該航海で得られた観測データを用いて評価した結果、短時間で予報誤差が成長する可能性が示された。東方伝播する中緯度帯の降水システムの季節内変動や亜寒帯から熱帯の低気圧性擾乱はよく予報できており、全体としてこのモデルは当該海域における現象に対しては高パフォーマンスであることが示された。","subitem_description_type":"Other"}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.1016/j.polar.2017.04.003"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1016/j.polar.2017.04.003","subitem_relation_type_select":"DOI"}}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"18739652","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Gera, Anitha","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Mahapatra, D.K.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sharma, Kuldeep","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Prakash, Satya","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Mitra, A.K.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Iyengar, G.R.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Rajagopal, E.N.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Anilkumar, N.","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Southern ocean","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Numerical weather prediction","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Westerly winds","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Sub -seasonal rainfall variability","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Sub polar low pressure systems","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Assessment of marine weather forecasts over the Indian sector of Southern Ocean","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Assessment of marine weather forecasts over the Indian sector of Southern Ocean"},{"subitem_title":"Assessment of marine weather forecasts over the Indian sector of Southern Ocean","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"37","path":["1844"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-09-01"},"publish_date":"2017-09-01","publish_status":"0","recid":"14356","relation_version_is_last":true,"title":["Assessment of marine weather forecasts over the Indian sector of Southern Ocean"],"weko_creator_id":"37","weko_shared_id":-1},"updated":"2023-07-25T15:15:09.251090+00:00"}
