| 摘要: | 台灣區域大氣水文觀測與預報實驗(TAHOPE)為台灣與美國雙方共同推動的國際觀測聯合實驗(美方為PRECIP2020)，預計於2020年以台灣區域為主體進行劇烈天氣(梅雨與颱風)觀測，所探討的研究主題，由大尺度的環境影響、中尺度的對流系統、乃至小尺度的雲物理過程，在台灣海島與高山陡坡特殊地形下，透過大氣水文觀測聯網導入先進大氣水及水文預報模式，同時進行即時或準即時同化分析與預報。為順利完成此雙邊聯合大型觀測與預報實驗，國研院颱洪研究中心在大氣學門同仁共同期許下，負責整合國內產官學研觀測儀器，邀請有興趣的同仁共同向科技部提出三年整合研究計畫(2018-2021)。目前美方已向美國NSF、NOAA提出多種觀測利器(P3飛機、S-PolKa雷達、C-Pol雷達、水汽通量觀測儀DIAL等)需求，將搭配國內己有的作業觀測設備(雷達及探空)、颱洪中心大氣水文觀測能量(C-Pol雷達、剖風儀、飛機投落送、無人飛機及試驗流域)，於2020年5月25日至9月底進行聯合觀測實驗，期間將特別對我國自主衛星(福衛7號)GPS掩星及海面反射儀觀測進行同化及預報的效益評估。美方主要計畫主持人為CSU教授Michael Bell 與Kristen Rasmussen，加上數位有興趣知名氣象學者。我方目前已成立計畫辦公室(颱洪中心黃清勇主任)，並已整合出子計畫群組(觀測實驗組、資料同化組、模式與分析組以及水文應用組)，由工作委員會四個分組召集人負責組成參與子計畫及協調分工，再由計畫辦公室及兩位顧問協助統整以強化管控，並由成立的科學指導委員會對規劃進行的實驗設計與科學目標，提出寶貴建議及修正意見。基於實驗本身的延伸及強化，我們同時也期待國際有興趣的芳鄰加入本實驗。 ;Taiwan-Area Atmospheric and Hydrological Observation and Prediction Experiment is an international joint project of Taiwan and U.S. (PRECIP2020) that will conduct observation experiments for severe weather (Mei-yu and typhoon) in the vicinity of Taiwan. The main themes of the project range from large-scale environmental influence, mesoscale convective systems as well as microscale cloud physics processes, under the special topography of Taiwan island with steep mountain. Through the joint network of atmospheric and hydrological observations, real-time or near real-time assimilation analysis and prediction will be conducted using advanced atmospheric and hydrological models. In order to accomplish this large bi-lateral joint observation and prediction experiments, Taiwan Typhoon and Flood Research Institute/National Applied Research Laboratories (TTFRI /NARLabs), on the expectation of meteorology community, takes a role in integrating the available domestic observation instruments and invites interested community colleagues to jointly submit an integrated three-year research proposal (1 August, 2018 – 31 July, 2021) to Ministry of Science and Technology (MOST), Taiwan. The U.S. Partners have submitted requests to U.S. National Science Foundation (NSF) and National Oceanic and Atmodpheric Administration (NOAA) on a variety of robust instruments (P3-aircraft, S-PolKa radar, C-Pol radar, vapor flux meter DIAL, etc.) to combine with Taiwan operational observation facilities (radars and radiosondes), atmospheric and hydrological measurements (C-Pol radar, wind profiler, dropsonde, aerosonde and experimental watershed) of TTFRI to perform joint observation experiment during 25 May to 30 September 2020; meanwhile, evaluation of data impact on assimilation and prediction from own domestic satellite (FORMOSAT-7) GPS RO and reflectometry measurements will be carried out, in particular. The U.S. partners include project principal investigators, Dr. Michael Bell and Kristen Rasmussen (CSU professors) and several renowned meteorologists. On Taiwan side, a project office lead by Director General of TTFRI, Dr. Ching-Yuang Huang, has been set up and has integrated four working subgroups, namely, Observation Experiment (OB), Data Assimilation (DA), Modeling and Analysis (MA), and Hydrological Application (HA). Each chair of four working groups (OB, DA, MA and HA) is mainly responsible for recruiting and collaborating participating sub-proposals that are then subject to further integration for consolidated coordination by the project office with help of two project consultants. The formed Scientific Advisory Committee consisting of local senior scientists in atmosphere and hydrology provides valuable comments and suggestions on the proposed scientific goals and experimental design of the joint project. For experimental extension and enhancement, we are also looking forward to seeing participation of international interested neighbourhood. |
