The Influence of Typhoon on the Guangdong Power Grid and Countermeasures
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. -

Globally the atmosphere and ocean is increasingly getting warmer, the amount of ice on the earth is decreasing over the oceans, and the sea level has risen. According to Intergovernmental Panel on Climate Change, the total increasing temperature globally averaged combined land and surface between the average of the 1850-1900 period and the 2003 to 2012 period is 0.78°C (0.72 to 0.85). But should we prepare for such the relatively small change? The importance is not the mean of the warming but the considerable likelihood of climate change that could trigger extreme natural hazards. The impact and the risk of climate change associated with railway infrastructure have not been fully addressed in the literature due to the difference in local environmental parameters. -

Owing to the scarcity of ocean Coupled model observations, the three-dimensional numerical modeling with high South China Sea resolution, as a powerful tool, offers a valuable opportunity to Typhoon investigate how the air–sea process proceeds under such extreme Response conditions. The amplitude and distribution of the cold path pro- duced by the coupled model compare reasonably well with the TRMM/TMI-derived data. The maximum SST cooling is 5.3 ◦C, about 80 km to the right of the typhoon track, which is consistent with the well-documented rightward bias in the SST response to typhoons. In correspondence to the SST cooling, the mixed layer depth exhibits an increase; the increases in the mixed layer depth on the right of typhoon track are significantly higher than those on the left, with maxima of 58 m.
