Three Gorges Area Faces 'Biggest Challenge' Society Three Gorges area faces 'biggest challenge' By Li Wenfang (China Daily) Updated: 2010-07-19 07:03 GUANGZHOU - The Three Gorges reservoir is expected to face its biggest challenge since its operation, with a major flood brewing at the upper reaches of the Yangtze River, water authorities said on Sunday. More than 70 firefi ghters in Leshan city of Sichuan province evacuate more than 1,000 farmers trapped by floods on Sunday. Continuous rainstorms inundated four villages in Jianong town of Leshan’s Shawan district on Sunday. [China News Service] The China Three Gorges Corporation forecast that floods as huge as those in 1998 will occur. The peak flow of the coming flood has been forecast at 70,000 cubic meters a second, greater than the 50,000 cubic meters a second during the flood in 1998, when 4,150 people were killed and 18.4 million residents evacuated. The Three Gorges navigation administration said on Saturday it will close ship locks if floods gush in at a speed of up to 45,000 cubic meters a second. At least 146 people have already been confirmed dead and 40 missing in 10 provinces and Chongqing municipality by Friday, after continuous rainstorms and floods in the areas since July 1, the Ministry of Civil Affairs said. Heavy rains have inflated water flow at both the mainstream and tributaries of the upper reaches of the Yangtze River, with inflow from the Minjiang, Tuojiang and Jialing rivers rising fast, said Wang Jun, director of the hydrology bureau under the Changjiang Water Resources Commission. Daily rainfall at the Jiuyuan monitoring station on the Jialing River hit 225 mm on Saturday. Inflow to the Cuntan monitoring station on the Yangtze River mainstream went up to 42,300 cubic meters a second at 3 pm on Sunday. Inflow to the Three Gorges reservoir will reach 53,000, 66,000 and 60,000 cubic meters a second at 8 am on Monday, Tuesday and Wednesday, respectively, the hydrology bureau forecast. With strong rains forecast along the Jinsha River on Thursday, inflow to the reservoir is also expected to approach 70,000 cubic meters a second. The Yangtze River flood control and drought relief office has been closely monitoring water in the river and adjusting the storage of the Three Gorges reservoir to help relieve mounting flood pressure along the middle and lower reaches of the Yangtze River, office director Wei Shanzhong said. Although the peak discharge at the upper reaches of the Yangtze River will surpass that in 1998, the duration and total flood volume will be less, the office said on Sunday. Flood pressure at the middle and upper reaches of the river should also lessen with control by the reservoir, it said. Still, Wei warned against water volume approaching or exceeding alert levels at monitoring stations such as those in Chenglingji, Jiujiang, Hankou and Datong at the river's middle and lower reaches. A number of dikes at the river's middle and lower reaches which have been under water pressure for a long time due to the continuous heavy rains are also susceptible to disaster, he said. The office of the State flood control and drought relief headquarters has ordered flood control and drought relief offices along the Yangtze to strengthen dam control, the China News Service reported. Sluicing at the Three Gorges Dam was also raised again on Saturday, from 32,000 cubic meters to 34,000 cubic meters, to save dam space for another round of rainfall coming in two or three days. About 38.216 million people have been affected and 1.315 million relocated in the inclement weather, Ministry of Civil Affairs showed. A total of 124,000 houses have also collapsed and another 327,000 damaged, with direct economic losses reported at 29.52 billion yuan, the ministry reported. The central government has allocated about 370 million yuan in relief funds to nine southern provinces battered by floods on Friday. Typhoon Conson also made landfall in Hainan province at 7:50 pm on Friday, toppling trees and billboards and killing at least two people. It battered 68 towns and villages in eight cities and flattened 544 houses in Hainan, with direct economic losses estimated at 240 million yuan. Conson brought heavy rain to parts of Guangdong province and the Guangxi Zhuang autonomous region. It weakened into a tropical storm on Saturday and made a second landfall in northern Vietnam on Saturday night. http://www.chinadaily.com.cn/china/2010-07/19/content_10121057.htm .

As of 10 August, four people were killed, some 8,000 people were left homeless, and 200 meters of railroads were washed away. More than 12,000 hectares of rice paddies were flooded in Kam Pot province alone. Floods Nov 1999 Continued torrential rains during October and early November caused flash floods and affected five southern provinces: Takeo, Kandal, Kampong Speu, Phnom Penh Municipality and Pursat. The report indicates that the floods affected 21,334 families and around 9,900 ha of rice field. IFRC's situation report dated 9 November stated that 3,561 houses are damaged/destroyed. So far, there has been no report of casualties. Flood Aug 2000 The second floods has caused serious damages on provinces in the North, the East and the South, especially in Takeo Province. Three provinces along Mekong River (Stung Treng, Kratie and Kompong Cham) and Municipality of Phnom Penh have declared the state of emergency. 121,000 families have been affected, more than 170 people were killed, and some $10 million in rice crops has been destroyed. Immediate needs include food, shelter, and the repair or replacement of homes, household items, and sanitation facilities as water levels in the Delta continue to fall.

    Typhoon Initialization in a Mesoscale Model — Combination of the Bogused Vortex and the Dropwindsonde Data in DOTSTAR Kun-Hsuan Chou and Chun-Chieh Wu Department of Atmospheric Sciences, National Taiwan University, Taipei, Taiwan Submitted to Monthly Weather Review (Revised on April 23, 2007) ___________________ Corresponding author address: Dr. Chun-Chieh Wu, Department of Atmospheric Sciences, National Taiwan University, No. 1, Sec. 4, Roosevelt Rd., Taipei 106, Taiwan. ([email protected]) Abstract Issues on the initialization and simulation of tropical cyclones by integrating both the dropwindsonde data and the bogused vortex into a mesoscale model have been studied. A method is proposed to combine the dropwindsonde data with the bogused vortex for the tropical cyclone initialization and to improve the track and intensity prediction. Clear positive impact of this proposed method on both the tropical cyclone track and intensity forecasts in a mesoscale model is demonstrated in three cases of typhoons, Meari (2004), Conson (2004) and Megi (2004). The effectiveness of the proposed method in improving the track and intensity forecasts are also demonstrated in the evaluation of all 10 cases of DOTSTAR (Dropwindsonde Observations for Typhoon Surveillance near the Taiwan Region) missions in 2004. This method provides a useful and practical means to improve the operational tropical cyclones prediction with the dropwindsonde observations. 1 1 Introduction Over the past 30 years, persistent and steady progress on the track forecasts of tropical cyclone (TC) have been well demonstrated through the improvement of the numerical models, the data assimilation and bogusing systems, the targeted observations, and the satellite and dropwindsonde data available to the forecast systems (Wu et al.

  • Annual Weather Review 2010 ______
    Annual Weather Review 2010 ____________________________________________________________________________ Review of Weather Conditions in 2010 Northeast Monsoon Season (Jan – March) 2010 started off with a mild Northeast Monsoon, with rainfall well below average for the first two months of the year. Not only was the 2009/2010 Northeast Monsoon unusual in not bringing the monsoon surges typical of the rainy season1, the period also saw the occurrence of Sumatra squalls on three almost consecutive days on 4, 6 and 7 January 2010. Sumatra squalls are associated with deep southwesterly winds and are uncommon during the Northeast Monsoon, during which the prevailing winds are predominantly from the opposite direction. The dry phase2 of the Northeast Monsoon set in during late January 2010 and extended to March 2010. The dry conditions usually experienced during this period are due to the strong cross equatorial flow induced by the migration of the monsoon rain belt far south of the equator away from Singapore. The absence of sufficient moisture coupled with the presence of strong divergent wind flow at the 700-850 hPa levels, impeded convective activity and suppressed rainfall during this period. In February 2010, the coincident passage of a dry phase of the Madden Julian Oscillation (MJO) and a moderate El-Niño over the maritime continent further exacerbated the dry conditions over Singapore and the surrounding region. As a result, February 2010 was the driest February for Singapore since rainfall records began in 1869, with only 6.3 mm of rainfall recorded at the climate station. Moreover, the dry phase of the Northeast Monsoon in 2010 had only 5 rain days and registered a total rainfall of merely 9.8 mm.

  • Reprint 1073 Application of Dvorak Technique During the Weakening
    Reprint 1073 Application of Dvorak Technique during the Weakening Stage of Tropical Cyclones C.T. Shum & S.T. Chan The 6th China-Korea Joint Workshop on Tropical Cyclones Shanghai, China 26-28 May 2013 APPLICATION OF DVORAK TECHNIQUE DURING THE WEAKENING STAGE OF TROPICAL CYCLONES C.T. SHUM and S.T. CHAN Hong Kong Observatory, Hong Kong, China Abstract The Dvorak technique has been widely used by operational warning centres in different parts of the world as a major analysis tool to determine the intensity of tropical cyclone (TC). However, there exist noticeable differences in the application of the technique among different warning centres. In particular, the weakening rules in the technique that governs the determination of TC intensity during the TC weakening stage constitute one such difference and are the subject of review in this paper. Three options to modify the weakening rules are introduced and evaluated based on verification against the best-track datasets from various centres. Keywords: Dvorak technique, tropical cyclones, weakening rules. 1. Introduction Based on the infrared imageries from geostationary satellites, the Enhanced Infrared (EIR) Dvorak technique (Dvorak, 1984) has long been used in the Hong Kong Observatory (HKO) as one of the references for estimating the intensity of tropical cyclones (TCs). Once a potential TC is suspected to be forming within the area 0o-36oN, 100o-140oE, Dvorak analysis will be performed at 6-hourly intervals. For TCs within the HKO area of responsibility (i.e. 10o-30oN, 105o-125oE), additional analysis will be performed at 3-hourly intervals. While Dvorak analysis serves as one of the important references in determining the maximum sustained surface wind speed (MSW) of the TC, surface wind reports, Doppler wind observations from weather radars, reconnaissance aircraft reports when available, wind scatterometer data and other objective analysis data, e.g.
