This study developed a fast storm surge ensemble prediction method based on TC track probability forecasting and searching optimization of a numerical scenario database (SONSD). In a case study of the Fujian Province coast (China), a storm surge scenario database was established using numerical simulations generated by 93 150 hypothetical TCs. In a GIS-based visualization system, a single surge forecast representing 2562 distinct typhoon tracks and the occurrence probability of overflow of seawalls along the coast could be achieved in 1–2 min. Application to the cases of Typhoon Soudelor (2015) and Typhoon Maria (2018) demonstrated that the proposed method is feasible and effective. Storm surge calculated by SONSD had excellent agreement with numerical model results (i.e., mean MAE and RMSE: 7.1 and 10.7 cm, respectively, correlation coefficient: .0.9).

Nowadays, ionospheric disturbances at a large-scale following typhoons can be monitored using ground-based dual-frequency Global Positioning System (GPS) observations. In this paper the responses of ionospheric total electron content (TEC) to Typhoon Maria on 10 July 2018 are studied by using about 150 stations of the GPS network in Taiwan. The results show that two significant ionospheric disturbances on the southwest side of the typhoon eye were found between 10:00 and 12:00 UTC. This was the stage of severe typhoon and the ionospheric disturbances propagated at speeds of 118.09 and 186.17 m/s, respectively. Both traveling ionospheric disturbances reached up to 0.2 TECU and the amplitudes were slightly different. The change in the filtered TEC time series during the typhoon was further analyzed with the azimuth.

  • Simulation the Impact of Typhoon Maria (2018) in Taiwan
    Simulation the Impact of Typhoon Maria (2018) in Taiwan Chia-hung Huang and Horng-syi Shen Department of Environmental Information and Engineering, Chung Cheng Institute of Technology, National Defense University ABSTRACT Typhoon Maria was the 8th typhoon in 2018. Under proper atmospheric condition, it reached severed typhoon on July 6. The intensity dropped due to the replacement of eye wall. On July 8, the intensity reached to severe after rapid intensification (RI). The colder sea surface temperature (SST) weakened the intensity of Maria. On July 10, Maria impacted Japan and Taiwan, made landfall over China on July 11 and then dissipated the next day. This study focus on the typical Northwest typhoon as it developed on the east side of Taiwan and channeled by the wind flow of higher pressure. However, the center of typhoon was deflected to north and thus didn’t develop into a Northwest typhoon. It moved through the northern sea and made landfall over China. The heavy rainfall and strong Northwest wind induced by Typhoon Maria caused heavy rainfall to northern Taiwan. Jhuzihu reached torrential rainfall of 306 mm. The purpose of this study is to simulate the track and heavy rainfall of Typhoon Maria. WRF 3.9 was conducted in this case study. Simulation started from 0000 UTC 10, July and processed for 48 hours, ended on 0000 UTC 12, July. Maximum rainfall simulated by 3 microphysic schemes in 24 hours (WSM5, WSM6 and ETA) were close to observation. Accumulated rainfall over 130 mm over mountainous area in North Taiwan was successfully simulated. Furthermore, the surface pressure simulation was also close to observation.
