6. Super Typhoon HAITANG (Feria/05w)    Print this Article
>> July 10-20, 2005

Haitang: contributed by China, is a Chinese flowering crabapple tree; also a Chinese flowering temple

A. Introduction & Storm Origins

Developing from a TUTT-induced disturbance deep within the subtropics, Haitang went on to become the Northwest Pacific basin's first super typhoon of the year, reaching a maximum intensity of 140 kts. Haitang made landfall on Taiwan as a weakening tropical cyclone but still came ashore as a major typhoon with a MSW of 105 kts. From there, it moved into China barely at typhoon intensity, the first tropical cyclone to affect the Asian mainland of 2005.

Super Typhoon Haitang originated from an area of deep convection that was located under the diffluent region of a TUTT cell approximately 760 nm east of Iwo Jima. It was first mentioned in JTWC's STWO at 1800 UTC 10 July when animated satellite imagery indicated a weak LLCC associated with the disturbance. Drifting slowly west through a light to moderate wind shear environment, the system developed rapidly and became the subject of a TCFA at 11/0300 UTC. The first warning became valid at 11/1200 UTC, placing the centre of Tropical Depression 05W approximately 600 nm east of Iwo Jima. It was upgraded to a tropical storm at 11/1800 UTC and named Haitang six hours later when JMA raised their MSW to 35 kts.

B. Track & Intensity History

Tropical Storm Haitang remained a weak system on 12 July as it drifted slowly towards the west-northwest at 5 to 8 kts. A HIGH centred south of Japan was the primary steering influence, guiding the tropical cyclone on a gentle, curving track across the Northwest Pacific. Tracking west-southwestward, Haitang strengthened into a 70-kt typhoon at 1800 UTC 13 July while located approximately 320 nm southeast of Iwo Jima. Turning towards the west, Haitang continued to steadily intensify on 14 July, its forward speed accelerating to around 19 kts. By the time the typhoon entered the Philippine AOR at 15/0600 UTC, the MSW had increased to 100 kts, and PAGASA assigned the name Feria. Strengthening continued on 15 July, and Haitang/Feria was upgraded to a super typhoon, the first of the year, while located approximately 405 nm south- southeast of Okinawa. The system reached its peak intensity of 140 kts at 16/1200 UTC while veering onto a west-northwesterly heading. At this time, water vapor imagery revealed a large, cloud-free eye and strong radial outflow. Haitang maintained an intensity of 140-kts for the rest of 16 July as it began to bear down on the island of Taiwan.

Super Typhoon Haitang began to weaken and was downgraded to a 125-kt typhoon at 0600 UTC 17 July approximately 255 nm southeast of Taipei, Taiwan. After changing onto a northwesterly course, Haitang's heading swung back to the west, and the typhoon made landfall near Hualein, located 85 nm south of Taipei, at 18/0000 UTC with a MSW of 105 kts. Once inland, the system rapidly became disorganized, and after almost stalling over the mountains of central Taiwan, Haitang slowly staggered the rest of the way across the island, re-emerging back over water as a 60-kt tropical storm at 18/1800 UTC. Moving west-northwestward, Haitang regained typhoon intensity (65-kts) at 19/0000 UTC over the Taiwan Strait. Turning north-northwestwards, the tropical cyclone rapidly deteriorated and made landfall near Fuzhou, China, as a weakening 40-kt tropical storm around 19/1200 UTC. At this time, both JTWC and JMA issued their final warnings.

NMCC's peak wind estimate was 130 kts (10 min avg), the highest of all the Asian agencies. Both JMA and PAGASA estimated a peak intensity of 105 kts; the lowest CP estimated by JMA was 915 mb. The highest MSW estimated by the CWB of Taiwan and HKO were 110 kts and 100 kts, respectively.

C. Damage & Casualties

At least twelve people were reported to have died as a result of Haitang. All of the deaths occurred on Taiwan; there were no reports of casualties in mainland China. Over one million people were evacuated from the Chinese provinces of Fujian and Zhejiang before the storm hit.

(NOTE: According to information from Huang Chunliang of Fuzhou City, there were 5 deaths attributed to Haitang on the Chinese mainland. See Section D-Part V below. Also, some of the damage figures in Chunliang's report differ from those given in the following two paragraphs, which were obtained from various international press sources.)

Haitang's torrential rains caused heavy flooding. In Cangnan County in Zhejiang Province, China, more than 300 people were trapped in their homes by floodwaters, which reached more than 3.3 feet (one metre), before being rescued. The county suffered power blackouts, cut water supplies, and power blackouts. The city of Wenzhou was also badly affected by the flooding. The Wenzhou Flood Control and Drought Relief Headquarters reported that 2,612 houses were destroyed and 16,700 hectares of crops were damaged. City officials said Haitang caused an economic loss of 2.16 billion yuan (261 million US dollars).

Haitang battered Taiwan with typhoon-force winds and torrential rains, wreaking havoc on the island. Haitang dumped more than 12 inches (305 mm) of rain across northern Taiwan, forcing airports, schools, government offices and financial markets to close. Transportation was badly affected with 90% of international flights cancelled and all domestic transport suspended. Strong winds disrupted power supplies with around 1.4 million households left without electricity. Around 1,500 people in northern Taiwan were evacuated from remote mountainous villages. The floodwaters washed away homes, roads, bridges, and decimated over 15,400 hectares of farmland, causing crop losses of nearly 30%. Haitang caused a total of T$2.97 billion (US$93 million) of damage to agriculture.

D. Huang Chunliang Report from China

{Part I} Landfalls

According to the CWB warnings, Severe Typhoon 0505 (HAITANG) made
landfall in Taiwan Island near Tungao, Ilan County, around 18/0650 UTC
with a MSW of 51 m/s (100 kts) and a CP of 925 hPa after making a
counter-clockwise loop offshore east of Hualien.  (The NMCC track also
described such a loop, despite the fact that the western part of the
loop was drawn overland near the coastline, i.e., NMCC stated that the
typhoon made its first landfall near Hualien around 18/0000 UTC with a
MSW of 55 m/s (110 kts) and a CP of 930 hPa before completing the 7-hr
loop around 18/0600 UTC and making a second landfall near Ilan around
18/0650 UTC with a MSW of 45 m/s (90 kts) and a CP of 940 hPa.)   The
typhoon then entered the waters of Taiwan Strait from Houlong, Miaoli
County, around 18/1400 UTC. 

According to the NMCC warnings, Typhoon 0505 (HAITANG) made landfall
near Huangqi Town, Lianjiang County, Fuzhou City, Fujian Province, 
around 19/0910 UTC with a MSW of 33 m/s (65 kts) and a CP of 975 hPa.

2. Rainfall Obs

During the 72-hr period ending at 20/0000 UTC, rains > 200 mm were
recorded in 9 counties/sub-cities of Fuzhou and Ningde Cities with
Zherong County reporting the highest amount of 665 mm.  (Guanyang, 
Ningde City, reported a 3-day total amounting to 780 mm----the 
highest of the hydrological stations during the same period.)

Extrema from Zherong County, Ningde City:

Daily rainfall: 472 mm [18/0000-19/0000Z] (a new record for the stn.)
6-hr rainfall: 158 mm [18/1800-19/0000Z]
3-hr rainfall: 130 mm [19/0000-19/0300Z]

3. Obs from Fuzhou City

The WMO station 58847 (Fuzhou) is only a few kilometers NE of my 
home. According to those reports from the station, we had 123 mm 
of rains within 24 hrs [18/0000-19/0000Z] before Haitang made 
landfall near Fuzhou's Lianjiang County as a minimal typhoon 
around 19/0910Z (per NMCC).  This was not too long before we 
received another very wet day, when the station reported 141 mm 
of rain [21/0000-22/0000Z], mainly recorded within 12 hrs [21/
1200-22/0000Z]  (It should be noted that 108 mm out of the total 
poured down within 6 hrs [21/1200-21/1800Z] from the periphery 
of the well-removed weakening depression.)   One of the urban 
stations even recorded rainfall amounting to 219 mm during the
same 12 hrs [21/1200-22/0000Z]!

As for the winds, the majority of the peak gusts were reported 
by stations in the city 24 hrs or so before landfall occurred 
when the still powerful typhoon was roaming over Taiwan Island.   
The urban area (WMO58847) reported 47 knots, while another two 
WMO stations, Changle (WMO58941) and Pingtan (WMO58944) both 
reported minimal typhoon force. Additionally, an insular station 
located on Pingtan Island recorded gusts topping 77 knots.

Nearly 9000 trees in the urban area of Fuzhou City were uprooted 
or partly damaged by Haitang's winds, though that occurred mainly 
on the 18th.  The day of landfall, the 19th, seemed much calmer
for my location. Actually, we even observed a decent rainbow on 
one occasion in the morning--very rare here during typhoons.  
(Interestingly, a press report indicated that another rainbow had 
been observed in Taipei City on the same day.)

{Part IV} Meteorological Obs from Zhejiang Province

reports indicated that Typhoon Haitang caused 12 deaths and left 
five people missing in Taiwan. Agricultural losses in the 
province were estimated to be at least NT$ 4.2 billion.
Preliminary statistics indicated that the typhoon caused 11.92
