3 I. Overview of Meteorological and Hydrological Conditions during the Year Meteorological Assessment The meteorological conditions in Vietnam during 2007 have been very complicated with several extreme weather events occurred all over our country, especially in the Central part of Vietnam together with 2 tropical storms and 1 tropical depression that exerted their direct impacts on our territory. Hot and dry weather condition occurred with less severe magnitude as compared to From late March to the end of June, many extended hot and dry spells (more than 10 days) occurred successively. In general, the average temperature from May to October was around and higher than average over the whole country. The extreme weather phenomena such as whirlwinds, hails, severe thunderstorms, lightning occurred more frequently than in 2006, especially the hail storm occurred on November 2006 over North West mountainous areas of Vietnam. Until October of this year, 31 people were killed, 132 were injured and hundreds of houses were destroyed. The TS No. 2 (NONAME) made landfall on Ha Tinh Quang Binh area, not far from Ky Anh station, in the evening of 8 th August. Although it was a small TS but had a very complicated track and it caused very serious damage to the central part of Vietnam (in term of human life, houses, traffics, aquaculture and agriculture). Note that this system was not classified as TS by other regional advisory Centers except Vietnam. The TYP No. 5 (TYP. LEKIMA) made landfall on Ha Tinh Quang Binh area in the evening of 3 rd October. The effects of this tropical storm include the strong winds with the gale force 12, gusted over 12 (Beaufort scale) in the coastal areas of provinces from Thanh Hoa to Quang Binh, and a heavy rainfall spell in large areas of Central part of Vietnam. The Tropical Depression No. 6 was formed over the waters of south Central Vietnam on 29 th October. It moved fast and made landfall on Binh Dinh province in the early morning of 30 th October, bringing winds of force 7, gusted over 7 (Beaufort scale) in provinces from Quang Ngai to Binh Dinh. This tropical depression circulation caused heavy rainfall of mm for 2 days. 2. Hydrological Assessment During the period from 01 st November 2006 to 15 th November 2007 Viet Nam was affected by large floods in Da, Hoang Long Rivers in the North and most serious flood, inundation in most rivers in the Central. Flood in the lower Mekong River in the South were lower than the annual average level. a) In the North: During flood season of 2007, in most rivers such as Hong, Thai Binh rivers occurred many low flood but with the peaks nearly I-alert values. Especially, the large 3

4 floods in Da and Hoang Long Rivers occurred very lately were higher than the III-alert values and exceeding the historical flood. Due to heavy rainfall by TYP No5 (LEKIMA) in combination with rather strong activity of southeast wind, from 03 to 06 October 2007, most serious, severe and complicated flood, inundation occurred in Son La, Hoa Binh, Ninh Binh provinces. The food peak in Hoang Long river at Ben De (Ninh Binh province) was 5,17 m (1:00, 6 th October 2007), nearly the historical flood in 1985 (5,24m), exceeding the alarm level 3 by 1,17 m. At 12:00, 6 th October 2007, the flood had to divert to 12 communes of 2 districts of Ninh Binh province. In Da river, the inflow to Hoa Binh reservoir concentrated very quickly for only 12 hours from 2000 m 3 /s (at 16:00 of 4 th October) to m 3 /s (at 07:00 of the 5 th October) was biggest value in October during the recent 100 year period and the Hoa Binh reservoir had to open 6 spillway gates to downstream in 12 hours. b) In the Central: Flood was very serious with successive and very high peaks, rather high flood rising intensity, flood water was concentrated very quickly and all these circumstances led to serious prolonged inundation in 12 provinces from Thanh Hoa to Ninh Thuan and the Highland. Particularly, within only more than one month from 1 st October to 12 th November 2007 in most rivers in Thua Thien Hue, Quang Nam, Quang Ngai, Binh Dinh, Phu Yen provinces, occurred 6 extremely big, historical floods such as: From 1 to 5 October, from 14 to 17 October, October, October, 1-2 November and 3 5 November. The Flood, inundation No-1 in early August 2007 Due to the affect of TS No2, from 05 to 08 August 2007, in most of coastal provinces of Central Viet Nam from Thanh Hoa to Thua Thien Hue heavy rainfall in a large area, in some places, extremely heavy rainfall with very high intensity was recorded. The common total rainfall per spell varied from 600 to 800 mm; in some places, the value was higher 1000 mm, (Huong Khe: 1369mm, Tuyen Hoa: 1279mm, Dong Tam: 1042mm. Historical, flash floods seriously occurred in whole Thanh Hoa, Nghe An and Gia Lai provinces. It was the biggest flood during the recent year period: flood peak in Ngan Sau river at Chu Le was 16,13 m (6:00, 7 th August 2007), exceeding the historical flood in 1996 by 0,71m, exceeding the alarm level 3 by 3,13 m; at Hoa Duyet, the value was 11,65 m (13:00, 8 th August), exceeding the alarm level 3 by 1,65m; in Gianh river at Dong Tam was 18,34 m (21:00, 7 th August 2007), nearly equaled to the historical flood in 1993, exceeding the alarm level 3 by 2,34 m; at Mai Hoa, the value was 9,47 m (23:00, 7 th August), exceeding the alarm level 3 by 3,47m higher flood peak in 1963 by 0,64 m; in Krong Buk river at Krong Buk was 458,39 m (10:00, 8 th August 2007), exceeding the historical flood in 1978 by 1,13m, exceeding the alarm level 3 by 2,08m. In many other rivers in Central Viet Nam, big flood occurred with the peak exceeding the alarm level 3 Flood, inundation No-2 in early October 2007 Due to the affect of TYP No5 (LEKIMA) in combination with rather strong activity of southeast wind, from 03 to 06 October 2007, in Son La, Hoa Binh, Ninh Binh provinces of the North Viet Nam and in most of coastal provinces of Central Viet Nam occurred heavy rainfall in a large area. 4

5 The common total rainfall per spell varied from 350 to 400 mm; in some places, the value was higher 500 mm, (km46: 783mm, Hung Thi: 518mm, Bat Mot: 788mm. The heavy rainfall caused the most serious, severe and complicated flood, inundation: - Flood rising intensity was very high, particularly, in rivers of Nghe An, Thanh Hoa, Ninh Binh, Son La provinces. At Quy Chau hydrological station, it was recorded that the average flood rising intensity was 50cm/h, the maximum value was 1,1 m/h; at Cua Dat, the average: 60 cm/h, maximum: 1,50m/h. Speed of flood run-off was the highest. - The flood amplitude was very big in rivers. The average flood amplitude was 8-10m during 12-24h, the maximum value at Quy Chau station of Hieu River (Nghe An province) was 12 m; at Thach Thanh station of Buoi River (Thanh Hoa province) was 10,25 m; at Hoi Xuan station of Ma River (Thanh Hoa province) was 13 m. - Flood peaks in rivers were very high Historical flood occurred in some rivers (in the recent year period): Water level at flood peak in Buoi river measured at Thach Thanh was 14,25 m (at 01:00 of the 6 th October), higher the historical flood in 1985 by 0,26 m; in Ma river at Cam Thuy, the value was 21,87 m (at 20:00 of 6 th October) higher the historical flood in 1975 by 0,16 m; at Ly Nhan 13,24m (at 4:00 of 6 th October) higher the historical flood in 1973 by 0,41 m, at Giang 7,28m (at 4:00 of 6 th October) nearly the historical flood in 1983 (7,51m), exceeding alarm level 3 by 0,78 m; in Hieu River at Quy Chau was 80,19 m (4:00, 5 th October 2007), exceeding the historical flood in 1988 by 0,14m. This serious flood in Thanh Hoa province caused a break of the dyke in Buoi river and the secondary dam of Cua Dat reservoir in Ma river led very serious inundation in large area. In many other rivers in Central Viet Nam, big flood occurred with the peak exceeding the alarm level 3 by 0,17-0,75m such as Huong (Thua Thien Hue province), Thach Han (Quang Tri province), Kien Giang and Gianh (Quang Binh province) rivers. Flood, inundation No 3 in early November 2007 Due to the affect of TS N-6 (PEIPAH) in combination with rather strong activity of southeast wind, from 09 to 13 November 2007, in most of coastal provinces of Central Viet Nam from Thua Thien Hue to Binh Dinh, occurred heavy rainfall in a large area. The common total rainfall for 4 days varied from 500 to 700 mm; in some places, the value was higher 800 mm, such as Nam Dong: 1773mm, Thuong Nhat: 1248mm, A Luoi: 834mm. The heavy rainfall caused the most serious, severe and complicated flood, inundation: The peak floods were extremely big, nearly historical flood in some rivers The flood peak in Han River at Cam Le station (Quang Nam province) was 3,98 m (at 19:00 of the 12 th November), nearly the historical flood in 1999, exceeding the alarm level 3 by 2,28 m; in Vu Gia River at Ai Nghia station (Quang Nam province) was 10,36 m (at 08:00 of the 12 th November), higher the historical flood in 1999 by 0,09m, exceeding the alarm level 3 by 1,56 m; in Thu Bon River at Cau Lau station (Quang Nam province) was 5,39 m (at 11:00 of the 12 th November), higher the historical flood in 1999 by 0,16m, exceeding the alarm level 3 by 1,69m, at Hoi An station was 3,28 m (at 15:00 of the 12 th November), higher the historical flood in

6 by 0,07m, exceeding the alarm level 3 by 1,58m; in Auyn River at PMoRe station (Gia Lai province) was 678,03 m (at 22:00 of the 10 th November), higher the historical flood in 1984 by 1,31m. The flood peak was higher than III-alert value in many rivers of 10 provinces, such as Thach Han River at Quang Tri station (Quang Nam province) (0,6m), Bo River at Phu Oc station (Thua Thien Hue province) (0,33), Ve river at Ve station (Quang Ngaii province) (0,99m), Lai Giang River at Bong Son station and Kon river at Thach Hoa station (Binh Dinh province), Ba River at Cung Son station and Da Rang river at Phu Lam (Phu Yen province), Cai Nha Trang River at Dong Trang station (Khanh Hoa province), Cai Phan Rang River at Tan My and Phan Rang stations (Ninh Thuan province), DacBla River at Kon Tumi station (Kon Tum Nam province),... c) In the South: In the lower Mekong River, the flood occurred more lately than 1 month compared with the annual average at Tan Chau and Chau Doc stations. The flood lasts from the end of July to 31 st October. Flood peaks occurred in 24 October 2007 and were lower the alarm level 3 by 0,12 m. Table 1.

10 Socio-economic Assessment Heavy rains and tropical storms followed by floods and flash floods caused major damage during summer The government has made every efforts and taken necessary measures for the prevention and mitigation of natural disaster. Due to TS No. 2 (NONAME), historical floods on Gianh and Krong Buk rivers was set and exceeded 0.64m and 1.13m the previous one on 1993 and 1978 respectively; 77 people were reported dead, 123 injured, 6 missing people; houses were collapsed and damaged; 51 ships were sank; ha of rice field were flooded. Due to TYP No. 5 (LEKIMA), the floods on some rivers in north Central Vietnam (Buoi and Ma rivers ). As a result, 88 people died, 180 injured and 8 missing people; houses were collapsed and damaged; 46 ships were sank; ha of rice fields were flooded. Although Tropical Depression No. 6 was formed and developed in a short time but its circulation caused heavy rains and floods in many rivers along the south of Central Vietnam. As a result of that, 07 people died, 01 missing and 92 injured people; 886 houses were damaged; 9416 ha of rice were flooded and damaged. 10

Hardware and Software Progress a.1 Observation network: NIL a.2 Technical advancement Visible and other imageries from MTSAT (JMA) were used in operational forecasting. Microwave imagery from the US Naval Research Laboratory website was used to support forecasters in locating the TC intensity and position a.3 Data exchange: NIL a.4 Numerical Weather Prediction The High Resolution Model (HRM) is operationally running with the increased horizontal resolution of 14km x 14km with the initial and boundary conditions interpolated from the DWD s global model GME. From 24 October, 2007, the multi-layer soil model comprises seven active layers for the heat (energy) and six for the soil moisture (water) budget has been used in GME. a.5 The use of ensemble products Multi-model ensemble and consensus forecasts of tropical cyclone tracks are used during the course of producing tropical cyclone warnings. The picture below illustrates probability forecast 24h and 48h conducted from forecasts system of kilo-members ensemble based on WBAR model. (a) (b) Fig 4: Example of accumulated probability forecast 24h and 48h conducted from forecasts system of kilo-members ensemble based on WBAR model 11

12 b. Implication to Operational Progress The outputs of the higher resolution version of HRM model, especially its rainfall forecasts (for the cases when typhoons affect our coastal areas) showed a good guidance in indicating the regions of heavy rainfall. It is especially true for the central part of Vietnam where high mountains are very close to the sea, and thus, the detailed topography of the model are helpful in representing the precipitating effects of the tropical cyclone circulation. The picture below demonstrates the accumulated 72h rainfall forecast from HRM model with the new seven layer soil model of GME. Fig 5: Accumulated precipitation (72h) from 00UTC 9 to 12 November 2007, observation (left) and forecasted from HRM model (right) With the intensive utilization of numerical guidance and multi-model consensus forecasts from different NWP models as well as subjective TC advisories, operational predictions and warnings of TC tracks performed quite well.
