2018 International Conference on Energy, Power, Electrical and Environmental Engineering (EPEEE 2018) ISBN: 978-1-60595-583-4 The Influence of Typhoon on the Guangdong Power Grid and Countermeasures 1 2 1 3,* Tuan-jie GAN , Jian-feng WEN , Lian-dong HUANG and Xue-jiao HAN 1Jiangmen Power Supply Company of Guangdong Power Grid Co., Ltd Guangdong 529000, China 2Guangdong Power Grid Co., Ltd Guangdong 510000, China 3Tsinghua University, Beijing 100084, China *Corresponding author Keywords: Typhoon, Transmission line, Distribution line, Countermeasures of wind disaster. Abstract. Guangdong affected by typhoon frequently, so power sectors pay high attention to the transmission line failure caused by the typhoon. Based on typhoon data in Guangdong, this paper gets characteristics of typhoon with a scientific method of the statistical analysis. By studying the loss of Jiangmen power grid caused by typhoon, this paper summarizes the cause of power accidents and puts forward countermeasures. It shows that typhoon mainly occurred between July and September in Guangdong, accounting for 72% of all the year round; Typhoon in Guangdong showed the tendency of reduced from west to east; Form 2008 to 2010, transmission line tripped 50 times caused by typhoon, and distribution circuit tripped 710 times in Jiangmen; The main reasons of breakdown are the mechanical overload, the flashover caused by wind age yaw and the reduction of air gap discharge voltage caused by lightning. This paper proposes to strengthen the early warning of typhoon, improve the design standard of transmission/ distribution line and develop new type tower material further study. Introduction Guangdong is located in the main path for northwest Pacific Ocean tropical cyclone and South China Sea tropical cyclone to land in China [1], which is one of the provinces suffering from the worst typhoon disaster. -

NASA Identifies Heavy Rainfall in South China Sea's Typhoon Utor 13 August 2013, by Rob Gutro
NASA identifies heavy rainfall in South China Sea's Typhoon Utor 13 August 2013, by Rob Gutro Visible and InfraRed Scanner (VIRS) at NASA's Goddard Space Flight Center in Greenbelt, Md. TRMM PR found rain falling at a rate of over 73mm/~2.9 inches per hour in well-defined thunderstorm feeder bands extending over the South China Sea. TRMM PR also found that heavy rain in these lines of rain were returning radar reflectivity values greater than 50.5 dBZ. When Utor was exiting the Philippines yesterday, Aug. 12, the storm's maximum sustained winds had fallen to 85 knots/97.8 mph/157.4 kph. By Aug. 13 at 1500 UTC/11 a.m. EDT the warm waters of the South China Sea had helped strengthen Utor, and maximum sustained winds were near 95 knots/109.3 mph/175.9 kph. Utor's center is located near 19.5 north and 113.1 east, about 190 nautical miles south- southwestward of Hong Kong. Utor is moving to the west-northwestward at 6 knots/7 mph/11.1 kph. Utor's powerful winds are generating very high, and NASA's TRMM satellite captured rainfall rates of over 73mm/hr (~2.9 inches) happening in Typhoon Utor on rough seas.

The Change in Rainfall from Tropical Cyclones Due to Orographic Effect of the Sierra Madre Mountain Range in Luzon, Philippines
Philippine Journal of Science 145 (4): 313-326, December 2016 ISSN 0031 - 7683 Date Received: ?? Feb 20?? The Change in Rainfall from Tropical Cyclones Due to Orographic Effect of the Sierra Madre Mountain Range in Luzon, Philippines Bernard Alan B. Racoma1,2*, Carlos Primo C. David1, Irene A. Crisologo1, and Gerry Bagtasa3 1National Institute of Geological Sciences, College of Science, University of the Philippines, Diliman, Quezon City, Philippines 2Nationwide Operational Assessment of Hazards, University of the Philippines, Diliman, Quezon City, Philippines 3Institute of Environmental Science and Meteorology, College of Science, University of the Philippines, Diliman, Quezon City, Philippines This paper discusses the Sierra Madre Mountain Range of the Philippines and its associated influence on the intensity and distribution of rainfall during tropical cyclones. Based on Weather and Research Forecasting model simulations, a shift in rainfall was observed in different portions of the country, due to the reduction of the topography of the mountain. Besides increasing the rainfall along the mountain range, a shift in precipitation was observed during Tropical Storm Ondoy, Typhoon Labuyo, and Tropical Storm Mario. It was also observed that the presence of the Sierra Madre Mountain Range slows down the movement of a tropical cyclones, and as such allowing more time for precipitation to form over the country. Wind profiles also suggest that the windward and leeward sides of mountain ranges during Tropical Cyclones changes depending on the storm path. It has been suggested that in predicting the distribution of rainfall, the direction of movement of a tropical cyclones as well as its adjacent areas be taken into great consideration. -
Near Real-Time Analysis of the Wind Structure of Tropical Cyclones
Near Real-time Analysis of the Wind Structure of Tropical Cyclones Nathaniel T. Servando Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) Quezon City, Philippines Ping-wah Li, Edwin Sau-tak Lai Hong Kong Observatory, 134A Nathan Road, Kowloon, Hong Kong ABSTRACT Real-time information on the wind structure of tropical cyclone is very useful for weather forecasters, in particular in the assessment of landfall impact. In this study, LAPS (Local Analysis and Prediction System, originally developed by FSL of NOAA) is used to objectively analyze near real-time wind observations on a high-resolution three-dimensional grid. The data used for the analysis come primarily from SYNOPS, automatic weather stations (AWS) over Hong Kong and the neighbouring Guangdong province, rawinsonde, wind profiler, Doppler and radar-based TREC winds, SATOBS and QuikSCAT. Wind fields from the Operational Regional Spectral Model (ORSM) of the Hong Kong Observatory (HKO) are utilized as first guess. The re-analyzed wind fields are then used to study the wind structure and intensity of tropical cyclones. Comparisons of wind analyses before and after landfall using three tropical cyclone cases are presented and the observed changes in wind structure and intensity described. Ingestion of more wind observations in such high-resolution re-analyses reveal some interesting features in the cyclone circulation, especially in the evolution of wind asymmetry within the vortex structure as a result of land-sea differences during landfall. 1. Introduction Considering the amount and variety of weather data pouring into the forecasting offices these days, it is reasonable to assume that effective processing and utilization of such information would naturally lead to more accurate analyses and hence more reliable forecasts and warnings. -

Occurrence of extreme water level events associated with tropical storms are often unpredicted and put coastal infrastructure and safety of coastal populations at risk. Hence, an improved understanding of the nature of storm surges and their components along the Vietnam coast is required. For example, a higher than expected extreme storm surge during Typhoon Kalmegi (2014) highlighted the lack of understanding on the characteristics of storm surges in Vietnam. Physical processes that influence the non-tidal water level associated with tropical storms can persist for up to 14 days, beginning 3–4 days prior to storm landfall and cease up to 10 days after the landfall of the typhoon. -

Summary of the 2013 Asian Summer Monsoon
Summary of the 2013 Asian Summer Monsoon 29 January 2014 Tokyo Climate Center, Japan Meteorological Agency 1. Precipitation and temperature Four-month total precipitation amounts based on CLIMAT reports covering the monsoon season (June – September) were more than 160% of the normal from northeastern China to eastern Mongolia, around northern China, in eastern and central Kazakhstan, in northern and southern Pakistan, from western China to central India, and in southern Indonesia. The corresponding values were less than 60% of the normal around southeastern South Korea and in parts of eastern and northwestern China (Figure 10). The amounts were mostly consistent with the distribution of outgoing longwave radiation (OLR) anomalies (Figure 12). Extremely heavy precipitation was seen from eastern India to Pakistan in June, from the Tohoku region of Japan to central China in July, and from northeastern China to eastern Kazakhstan in August. In contrast, extremely light precipitation was seen around the Kyushu region of Japan in July (figures not shown). Four-month mean temperatures for the same period were more than 1°C above normal from Japan to South Korea and around eastern to central and western China, and were more than 1°C below normal around eastern Mongolia, northeastern Kazakhstan and central India (Figure 11). Heavy rain is reported to have caused more than 600 confirmed fatalities and 5,700 presumed fatalities in India as well as more than 50 fatalities in Nepal in June. It was also reported that heavy rain caused more than 200 fatalities in Pakistan and more than 60 in Afghanistan in August.
