In order to estimate the impacts of tide-surge interactions on storm surge elevations, Typhoon 7203 was assumed to arrive at 12 different times, with all other conditions remaining constant. This allowed simulation of tide and total water levels for 12 separate cases. Numerical simulation results for Yingkou, Huludao, Shijiusuo, and Lianyungang tidal stations were analyzed. Model results showed wide variations in storm surge elevations across the 12 cases. The largest difference between 12 extreme storm surge elevation values was of up to 58 cm and occurred at Yingkou tidal station. The results indicate that the effects of tide-surge interactions on storm surge elevations are very significant. It is therefore essential that these are taken into account when predicting storm surge elevations.

NASA's Aqua Satellite Sees Tropical Storm Haikui Make Landfall in China 8 August 2012
NASA's Aqua satellite sees Tropical Storm Haikui make landfall in China 8 August 2012 Typhoon Haikui weakened to a tropical storm just Center before landfall in China. Eight hours after landfall, NASA's Aqua satellite still showed a strong and organized tropical storm moving inland. China's National Meteorological Center (NMC) said that Tropical Storm Haikui, made landfall in Zhejiang province on August 8 at 3:20 a.m. local time (19:20 UTC or 3:20 p.m. EDT/U.S., August 7), about 140 miles (225 km) south of Shanghai. The Joint Typhoon Warning Center's last official warning on Haikui was issued on August 8 at 0300 UTC (11 a.m. local time/Shanghai). At that time Haikui's maximum sustained winds were near 60 knots (69 mph/111.1 kmh) and it was located about 95 miles south of Shanghai, near 29.7 North latitude and 121.3 East longitude. It was moving to the northwest at 9 knots (10.3 mph/16.6 kmh). By 5 p.m. EDT Shanghai local time on August 8 Haikui was located near the city of Huzhou. NMC reported heavy rainfall with totals as high as 17 inches (434 millimeters) in Xiangshan, Taizhou, and Ninghai, all located in the southeast coastal province of Zhejiang. A visible image of Tropical Storm Haikui was captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument that flies onboard NASA's Aqua satellite on August 8, 2012 at 0520 UTC (1:20 a.m. EDT/1:20 p.m. Shanghai local time) after it made landfall south of Shanghai, China. -
Research Article Application of Buoy Observations in Determining Characteristics of Several Typhoons Passing the East China Sea in August 2012
Hindawi Publishing Corporation Advances in Meteorology Volume 2013, Article ID 357497, 6 pages http://dx.doi.org/10.1155/2013/357497 Research Article Application of Buoy Observations in Determining Characteristics of Several Typhoons Passing the East China Sea in August 2012 Ningli Huang,1 Zheqing Fang,2 and Fei Liu1 1 Shanghai Marine Meteorological Center, Shanghai, China 2 Department of Atmospheric Science, Nanjing University, Nanjing, China Correspondence should be addressed to Zheqing Fang; [email protected] Received 27 February 2013; Revised 5 May 2013; Accepted 21 May 2013 Academic Editor: Lian Xie Copyright © 2013 Ningli Huang et al. This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. The buoy observation network in the East China Sea is used to assist the determination of the characteristics of tropical cyclone structure in August 2012. When super typhoon “Haikui” made landfall in northern Zhejiang province, it passed over three buoys, the East China Sea Buoy, the Sea Reef Buoy, and the Channel Buoy, which were located within the radii of the 13.9 m/s winds, 24.5 m/s winds, and 24.5 m/s winds, respectively. These buoy observations verified the accuracy of typhoon intensity determined by China Meteorological Administration (CMA). The East China Sea Buoy had closely observed typhoons “Bolaven” and “Tembin,” which provided real-time guidance for forecasters to better understand the typhoon structure and were also used to quantify the air-sea interface heat exchange during the passage of the storm. -
Peninjauan Status Lingkungan Eksisting Sungai Marikina, Filipina
Jurnal Teknik Lingkungan Volume 26 Nomor 2, Oktober 2020 (Hal 61 – 72) PENINJAUAN STATUS LINGKUNGAN EKSISTING SUNGAI MARIKINA, FILIPINA REVISITING THE CURRENT ENVIRONMENTAL STATUS OF THE MARIKINA RIVER, PHILIPPINES 1 2 Marwin Crispino and Eligia Clemente University of the Philippines Diliman, Quezon City, Philippines 1 2 Email: [email protected] and [email protected] Abstract: The physico-chemical characteristics of the Marikina River in an urban area of Metro Manila, Philippines was determined to evaluate the current degree of pollution. The study focused on one source at the site with general coordinates of 14°38’07.95” N, 121°05’36.33” E based on the World Geodetic System (WGS), at an average surface water elevation of around 9 m above mean sea level (AMSL). The area was chosen because of its proximity to a main road and the presence of an outfall from a cemented pipe near a major shopping mall. Comparing the results from the sampling source with the DENR effluent standards for surface waters based on (DAO-2016-08, US-EPA), the effluent is considered as too polluted to be discharged to the surface water in terms of Total Dissolved Solids (TDS: 608.9 mg/L) and Phosphates (PO4: 12.46 mg/L). The pH (6.9) and Nitrate (0.17 mg/L) of the effluent conforms to standards. A Stream Visual Assessment Protocol was conducted with a resulting Protocol Score of 5.7, which is relatively low for a moving water body. The failure to conform to set standards using the physico-chemical components is supported by the land-use profile which shows that domestic (85%), industrial/commercial (10%) and agricultural wastes (5%) greatly affect the water quality of the river. -

Philippines Floods Fact Sheet#1
FACT SHEET #1, FISCAL YEAR (FY) 2012 AUGUST 20, 2012 PHILIPPINES – FLOODS KEY DEVELOPMENTS In early August, heavy monsoon rains exacerbated by Typhoon Haikui caused flooding in the Manila metropolitan area and much of northern and eastern Philippines, killing 109 people, displacing approximately 1.1 million others, and affecting nearly 4.2 million individuals, according to the Government of the Philippines (GPH) Department of Social Welfare and Development (DSWD). The disaster prompted the GPH to launch search-and-rescue efforts; provide food, potable water, and clothing to displaced populations; and announce that it is prepared to release approximately $143 million in disaster assistance funds for flood response activities throughout the country. On August 7, 2012, U.S. Ambassador Harry K. Thomas Jr. declared a disaster due to the effects of the floods. In response, USAID’s Office of U.S. Foreign Disaster Assistance (USAID/OFDA) has provided $500,000 for distribution of relief supplies to flood-affected populations, as well as emergency logistics and water, sanitation, and hygiene (WASH) support. From August 8 to 10, USAID/OFDA East Asia regional staff assessed flood-affected areas of metropolitan Manila and provinces in Central Luzon and Calabarzon regions, noting that GPH agencies are managing the situation well, with no immediate, life-threatening conditions observed. Representatives from the Australian Government Overseas Aid Program (AusAID) joined the first day of the assessment, and USAID/OFDA, U.S. Government staff based in the Philippines, and relief agency partners conducted a second assessment in Rizal Province on August 15. USAID/OFDA staff note that the humanitarian situation appears to be stabilizing, particularly in Manila, where floodwaters continue to recede and families are returning to their houses. -
