Dissipating on May 18, and due to the strong pull of the outflow of Typhoon Nida at peak intensity, the remnants of 05W rapidly moved and was located about east of Philippines and was absorbed by a trough on May 20.

[14] By 0600 UTC on August 6, the eye was no longer visible on satellite imagery and several hours later deep convection rapidly diminished, leading to both agencies downgrading the typhoon to a tropical storm.

[15] Later on August 6, the weakening trend briefly halted as outflow significantly improved due to an area of low pressure north of Meranti.

On August 5, the JTWC began monitoring a persistent area of convection to the north-northwest of Guam;[18] accompanied by a low-pressure system, the disturbance developed into a tropical depression the following day.

A reverse-oriented monsoon trough extended from the Philippine Sea northeastward for hundreds of miles spawned a disturbed area around 22N/150E late on August 8.

After fluctuating between 100 kn/115 mph and super typhoon status for several days, Chaba weakened as it turned to the north, and hit the southwestern Japanese island of Honshū.

On the 23rd, Typhoon Aere was downgraded to a tropical storm briefly due to vertical wind shear while located 200 miles south of Naha, Okinawa.

Thirty-four people were killed in Taiwan as a result of the storm, and fifteen died as a mudslide buried a remote mountain village in the north of the island.

[22] On August 24, an area of convection with a possible weak low-level circulation center developed approximately 1,125 km (699 mi) east-southeast of Guam, and was moving slowly towards the west-northwest.

[23] By later that day, the center had become fully exposed with the deep convection being displaced westward over Guam, due to strong outflow from Typhoon Chaba to its north.

[19] Light wind shear and favorable diffluence allowed the system to strengthen, prompting the JTWC to issue their first advisory on Tropical Depression 22W the next day.

[25] By the morning of August 28, both agencies had upgraded the system to a tropical storm, with the JMA assigning it the name Songda, a branch of the Red River in northern Vietnam.

Early on September 5, Songda brushed the northern coast of Okinawa Island, where a barometric pressure of 925 mbar (hPa; 27.32 inHg) was recorded.

[18] The remnants of Songda were monitored by the JMA until late on September 10, at which time they crossed the International Date Line near the Aleutian Islands.

[19] Throughout Songda's track, several islands were affected; Enewetak Atoll recorded tropical storm-force winds with gusts up to 120 km/h (75 mph) during the storm's passage.

Later that day, the newly formed tropical depression saw its thunderstorms track across Taiwan, leaving the circulation center behind east of the mountainous isle as it took on a subtropical appearance.

Haima soon become a completely sheared system due to interaction with the upper-level winds over a frontal zone located to its west, and was declared dissipated the next day.

The storm damaged 78 square kilometres of farmland in Zhejiang Province, China, where direct economic losses were estimated to have been over 53 million yuan.

Torrential rains (Sep 7–10), including those in the monsoonal flow around the pre-Haima depression had caused 54.6 million yuan of direct economic losses in Pingtan County and Changle City.

After crossing the Philippine Archipelago, the depression began to slowly weaken but limped across the South China Sea to near the central Vietnamese coastline before dissipating on the 18th where it dropped moderate to heavy rainfall.

Typhoon Meari made landfall over the southern tip of Kyūshū around midday local time with maximum sustained winds of 70 kn/80 mph.

The worst affected areas were the prefectures of Mie and Ehime in Japan where torrential rains caused widespread flooding and mudslides destroyed several homes.

Recurving northeast at a high rate of translation, Ma-on made landfall on the Izu Peninsula, Japan, late on the 9th with maximum sustained winds of 105 kn/120 mph as a Category 3 typhoon.

By October 21, the cyclone weakened into a tropical storm 130 nmi west of Tokyo, and later that day, the system completed the transition to a nontropical low.

Turning to a northerly track, Typhoon Nock-ten passed closest to Taipei during the afternoon of October 25, lying just off the northeastern tip of Taiwan by evening.

Now moving west-southwest, early on the 22nd Muifa re-strengthened into a 90-kn/105 mph typhoon 440 miles east of Ho Chi Minh City, Vietnam.

According to news reports in the Philippines, 1,404 people were killed or left missing[30] during the passage of Tropical Depression Winnie, primarily due to massive flashfloods and landslides in Quezon and Aurora provinces triggered by the attendant heavy rains.

Turning northwestward Typhoon Nanmadol took roughly six hours to cross the island of Luzon, and by early on December 3 had re-emerged back over water.

The remnants of Super Typhoon Nanmadol continued to rapidly move to the east-northeast and northeast and ultimately merged with another low-pressure area, forming a powerful extratropical cyclone which brought strong winds and led to unseasonably warm temperatures to Japan.

Because Muifa, Merbok, Winnie, and Nanmadol all occurred within a space of two weeks, the exact number of casualties and total cost of damages is difficult to determine.
