An evaluation of wind speeds retrieved by variational multiple-Doppler analyses using radial velocities (Vr) based on the formats of both a Plan Position Indicator (PPI) (hereafter, PPI-VAR) and a Constant Altitude Plan Position Indicator (CAPPI) (hereafter, CAPPI-VAR) was performed for comparison with wind speeds observed by a wind profiler during the warm season of three consecutive years. The statistical analysis showed that PPI-VAR was more accurate than CAPPI-VAR at 500 m above ground level (AGL). The error of CAPPI-VAR at 500 m AGL was caused by a representative error of CAPPI-formatted Vr derived from a certain radar whose beam height was far from the analysis level, and this error became more obvious the greater the vertical difference in wind speed across the analysis level. CAPPI-VAR uses CAPPI-formatted Vr from each radar equally; thus, the representative error might cause performance degradation of CAPPI-VAR at 500 m AGL. Conversely, PPI-VAR uses PPI-formatted Vr from each radar with appropriate weighting based on the beam height distance from the analysis level. PPI-VAR showed better results at 500 m AGL because the observation grid points were dense around 500 m AGL.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"METEOROLOGICAL SOC JAPAN","subitem_publisher_language":"en"}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.2151/sola.2016-043"}}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1349-6476","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Ken-ichi Shimose","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Shingo Shimizu","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Takeshi Maesaka","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Ryohei Kato","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Kaori Kieda","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Koyuru Iwanami","creatorNameLang":"en"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_title":"Impact of Observation Operators on Low-Level Wind Speed Retrieved by Variational Multiple-Doppler Analysis","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Impact of Observation Operators on Low-Level Wind Speed Retrieved by Variational Multiple-Doppler Analysis","subitem_title_language":"en"}]},"item_type_id":"40001","owner":"1","path":["1670839190650"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-03-30"},"publish_date":"2023-03-30","publish_status":"0","recid":"5561","relation_version_is_last":true,"title":["Impact of Observation Operators on Low-Level Wind Speed Retrieved by Variational Multiple-Doppler Analysis"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-08T09:25:46.548179+00:00"}
