Ensemble Forecast Experiment for Typhoon
Ensemble Forecast Experiment for Typhoon Quantitatively Precipitation in Taiwan Ling-Feng Hsiao1, Delia Yen-Chu Chen1, Ming-Jen Yang1, 2, Chin-Cheng Tsai1, Chieh-Ju Wang1, Lung-Yao Chang1, 3, Hung-Chi Kuo1, 3, Lei Feng1, Cheng-Shang Lee1, 3 1Taiwan Typhoon and Flood Research Institute, NARL, Taipei 2Dept. of Atmospheric Sciences, National Central University, Chung-Li 3Dept. of Atmospheric Sciences, National Taiwan University, Taipei ABSTRACT The continuous torrential rain associated with a typhoon often caused flood, landslide or debris flow, leading to serious damages to Taiwan. Therefore the quantitative precipitation forecast (QPF) during typhoon period is highly needed for disaster preparedness and emergency evacuation operation in Taiwan. Therefore, Taiwan Typhoon and Flood Research Institute (TTFRI) started the typhoon quantitative precipitation forecast ensemble forecast experiment in 2010. The ensemble QPF experiment included 20 members. The ensemble members include various models (ARW-WRF, MM5 and CreSS models) and consider different setups in the model initial perturbations, data assimilation processes and model physics. Results show that the ensemble mean provides valuable information on typhoon track forecast and quantitative precipitation forecasts around Taiwan. For example, the ensemble mean track captured the sharp northward turning when Typhoon Megi (2010) moved westward to the South China Sea. The model rainfall also continued showing that the total rainfall at the northeastern Taiwan would exceed 1,000 mm, before the heavy rainfall occurred. Track forecasts for 21 typhoons in 2011 showed that the ensemble forecast has a comparable skill to those of operational centers and has better performance than a deterministic prediction. With an accurate track forecast for Typhoon Nanmadol, the ability for the model to predict rainfall distribution is significantly improved. -
An Experimental Analysis of Resilience in Urban Flood Management in the Taipei Basin
Resilience in Space: An experimental analysis of resilience in urban flood management in the Taipei Basin Hsu Chia Sui Email: [email protected] Thesis Supervisor: Kimberly Nicholas Email: [email protected] A thesis submitted in partial fulfillment of the requirements of the Lund University International Master’s Programme in Environmental Studies and Sustainability Science (LUMES), May 2011 Abstract The existing paradigm of flood management in the Taipei Basin prioritizes structural measures over non-structural measures. This strategy is not sufficiently flexible, particularly in light of increasingly frequent extreme weather. Resilience theory is concerned with the capacity of a system to absorb disturbance and retain its same functions. This study offers new insight by conceptualizing resilience in urban flood management. In particular, it demonstrates to what extent resilience theory as used in research on social-ecological systems was useful in developing a better plan for urban flood management. The study comprises a resilience assessment of flood management in Taipei based on guidelines in a workbook for scientists published by the Resilience Alliance. This study identified the external shocks to the flood management system in the Taipei Basin include typhoons, evidence of increasingly frequent extreme weather, groundwater mining and resulting land subsidence, and rapid urbanization. This study also includes a historical profile of major flooding and hydraulic projects from 1960 to 2010 and analyzes phases in terms of an adaptive cycle. The study concludes that resilience theory was an effective approach to investigating external shocks and stress to the system. Furthermore, the qualitative approach to apply resilience was a useful discourse for envisioning a better urban flood management system. -

E-mail: [email protected] Due to the interaction between Morakot and a monsoon system, a peripheral gale force monsoon surge appears to the south of Taiwan. The monsoon surge remains even in a sensitivity experiment in which Taiwan terrain is reduced. However, the rainfall amount in Taiwan is greatly reduced without high topography over Taiwan, suggesting the important role the local topography plays in producing heavy rainfall. The overall numerical results Received: 22 September 2009 indicate that it is the interaction among the typhoon, monsoon system, and local terrain that Revised: 29 November 2009 led to this extreme event.

Probabilistic Evaluation of the Dynamics and Prediction of Supertyphoon Megi (2010)
1562 WEATHER AND FORECASTING VOLUME 28 Probabilistic Evaluation of the Dynamics and Prediction of Supertyphoon Megi (2010) CHUANHAI QIAN Nanjing University of Information Science and Technology, Nanjing, and National Meteorological Center, Beijing, China, and Department of Meteorology, The Pennsylvania State University, University Park, Pennsylvania FUQING ZHANG AND BENJAMIN W. GREEN Department of Meteorology, The Pennsylvania State University, University Park, Pennsylvania JIN ZHANG National Meteorological Center, Beijing, China XIAQIONG ZHOU NOAA/NCEP, College Park, Maryland (Manuscript received 21 November 2012, in final form 21 July 2013) ABSTRACT Supertyphoon Megi was the most intense tropical cyclone (TC) of 2010. Megi tracked westward through the western North Pacific and crossed the Philippines on 18 October. Two days later, Megi made a sharp turn to the north, an unusual track change that was not forecast by any of the leading operational centers. This failed forecast was a consequence of exceptionally large uncertainty in the numerical guidance—including the operational ensemble of the European Centre for Medium-Range Weather Forecasts (ECMWF)—at various lead times before the northward turn. This study uses The Observing System Research and Predictability Experiment (THORPEX) Interactive Grand Global Ensemble dataset to examine the uncertainties in the track forecast of the ECMWF operational ensemble. The results show that Megi’s sharp turn is sensitive to its own movement in the early period, the size and structure of the storm, the strength and extent of the western Pacific subtropical high, and an approaching eastward-moving midlatitude trough. In particular, a larger TC (in addition to having a stronger beta effect) may lead to a stronger erosion of the southwestern extent of the subtropical high, which will subsequently lead to an earlier and sharper northward turn. -
The Eyewall-Penetration Reconnaissance Observation of Typhoon Longwang (2005) with Unmanned Aerial Vehicle, Aerosonde
JANUARY 2008 L I N A N D L E E 15 The Eyewall-Penetration Reconnaissance Observation of Typhoon Longwang (2005) with Unmanned Aerial Vehicle, Aerosonde PO-HSIUNG LIN AND CHENG-SHANG LEE Department of Atmospheric Sciences, National Taiwan University, Taipei, Taiwan (Manuscript received 18 September 2006, in final form 18 April 2007) ABSTRACT In this paper, a successful eye-penetration reconnaissance flight by an unmanned aerial vehicle, Aerosonde, into Typhoon Longwang (2005) and the preliminary analyses of the collected data are pre- sented. The 10-h flight is diagnosed through four flight legs. The wind field measured along flight leg 1 provides the tangential and radial wind profiles from the outer perimeter into the eye of the typhoon at the 700-hPa layer. A vertical sounding was taken in the eye along flight leg 2 and the derived surface pressure in the eyewall is close to the estimates made by the local weather agencies. Along flight leg 3, the strongest winds during the whole flight mission were measured. These in situ wind measurements by Aerosonde are consistent with the winds observed by the Hua-lien Doppler weather radar. The maximum 10-min (1 min) wind along flight leg 3 when Aerosonde was flying around the eyewall region is 58.6 m sϪ1 (62 m sϪ1). The maximum sustained surface wind derived from this maximum wind speed is also close to the estimates made by the local weather agencies. In conclusion, this successful mission demonstrates that the Aerosonde with a trained crew can play a role in severe weather monitoring and the Aerosonde’s measurement can serve as an independent check for Doppler radar wind retrieval. -

7 the Analysis of Storm Surge in Manila Bay, the Philippines
INTERNATIONAL HYDROGRAPHIC REVIEW MAY 2019 THE ANALYSIS OF STORM SURGE IN MANILA BAY, THE PHILIPPINES By Commander C. S. Luma-ang Hydrography Branch, National Mapping and Resource Information Authority, (Philippines) Abstract In 2013, Typhoon Haiyan produced a storm surge over seven metres in San Pedro Bay in the Philippines that killed approximately 6,300 people. The event created significant public awareness on storm surges and exposed the lack of records and historical research in the Philippines. This study investigated the tidal height records during intense cyclone activities in 2016 and 2017 to provide accurate information about storm surge development in the largest and most populated coastal area in the country – Manila Bay. The results of this investigation indicated that there are consistencies in the characteristics of tropical cyclones that produce larger storm surges. The results also show that actual storm surge heights are generally smaller than predicted height values. Résumé En 2013, le typhon Haiyan a provoqué une onde de tempête de plus de sept mètres dans la Baie de San Pedro aux Philippines, faisant près de 6 300 victimes. Cet événement a provoqué une importante sensibilisation du public envers les ondes de tempête et a mis en évidence le manque d’archives et de recherches historiques aux Philippines. La présente étude a examiné les enregistrements des hauteurs des marées au cours d’activités cycloniques intenses en 2016 et 2017 afin de fournir des informations précises sur le développement d’ondes de tempête dans la zone côtière la plus étendue et la plus peuplée du pays, la Baie de Manille. -

Assimilating AMSU-A Radiance Data with the WRF Hybrid En3dvar System for Track Predictions of Typhoon Megi (2010)
ADVANCES IN ATMOSPHERIC SCIENCES, VOL. 32, SEPTEMBER 2015, 1231–1243 Assimilating AMSU-A Radiance Data with the WRF Hybrid En3DVAR System for Track Predictions of Typhoon Megi (2010) SHEN Feifei∗ and MIN Jinzhong Collaborative Innovation Center on Forecast and Evaluation of Meteorological Disasters, Nanjing University of Information Science & Technology, Nanjing 210044 (Received 28 October 2014; revised 12 December 2014; accepted 29 December 2014) ABSTRACT The impact of assimilating radiances from the Advanced Microwave Sounding Unit-A (AMSU-A) on the track prediction of Typhoon Megi (2010) was studied using the Weather Research and Forecasting (WRF) model and a hybrid ensemble three- dimensional variational (En3DVAR) data assimilation (DA) system. The influences of tuning the length scale and variance scale factors related to the static background error covariance (BEC) on the track forecast of the typhoon were studied. The results show that, in typhoon radiance data assimilation, a moderate length scale factor improves the prediction of the typhoon track. The assimilation of AMSU-A radiances using 3DVAR had a slight positive impact on track forecasts, even when the static BEC was carefully tuned to optimize its performance. When the hybrid DA was employed, the track forecast was significantly improved, especially for the sharp northward turn after crossing the Philippines, with the flow-dependent ensemble covariance. The flow-dependent BEC can be estimated by the hybrid DA and was capable of adjusting the position of the typhoon systematically. The impacts of the typhoon-specific BEC derived from ensemble forecasts were revealed by comparing the analysis increments and forecasts generated by the hybrid DA and 3DVAR.
