Question: Why is Typhoon dot known by another name in other parts of the world?

Context paragraphs:
Typhoon Babe (1977): Typhoon Babe, also known as the Okinoerabu Typhoon (沖永良部台風 , Okinoerabu Taifū ) , was regarded as "the worst typhoon to threaten Japan in 18 years."  Developing as a tropical depression on September 2, Babe initially tracked west-northwestward as it intensified.  On September 5, an abrupt shift in steering currents caused the system to turn north-northwestward.  Early on September 6, the system intensified into a typhoon.  Over the following two days, Babe quickly intensified, ultimately attaining its peak intensity early on September 8 with winds of 240 km/h (150 mph) and a barometric pressure of 905 mbar (hPa; 26.72 inHg).  Not long after reaching this strength, another shift in the steering patterns caused the typhoon to execute a prolonged counter-clockwise arc, causing it to track through the Ryukyu Islands southwest of Japan, as it interacted with a low pressure originating from the Korean Peninsula.  During this time, the system gradually weakened and eventually it made landfall near Shanghai, China on September 11 as a minimal typhoon before dissipating inland the following day.  Coincidentally, Typhoon Babe and Atlantic Hurricane Babe existed at the same time from September 3–9.

Typhoon Ike: Typhoon Ike, known in the Philippines as Typhoon Nitang, was the deadliest typhoon of the 1984 Pacific typhoon season and crossed the Philippines in September.  This tropical cyclone formed on August 27 in the Philippine Sea, and strengthened as it moved westward into the southern Philippines, becoming a typhoon on August 31.  Typhoon Ike caused extreme wind and flooding damage when it crossed the Philippines, resulting in 1492 fatalities, one of the Philippines' worst natural disaster in modern times, and its worst typhoon since Amy struck the archipelago in 1951.  A total of 200,000 to 480,000 were left homeless.  Emerging from the Philippines as a strong tropical storm, Ike restrengthened as it tracked northwest through the South China Sea across northeast Hainan Island.  Weakening back into a tropical storm, Ike moved inland into mainland China.  In Hong Kong, winds gusted to 49 kn at Tate's Cairn.  Extensive crop damage was experienced in southern China, with Ike becoming the most significant tropical cyclone to strike Guangxi since 1954.  The total damage was reportedly US$111 million (1984 dollars).  The name Ike was retired after this season.  Typhoon Ike was recorded with a 220 km/h gust and an estimated 185 km/h msw in Surigao on September 2 and is one of the intense tropical cyclones and devastating and deadliest to hit the Philippines.

Typhoon Gay (1992): Typhoon Gay, known in the Philippines as Typhoon Seniang, was the strongest and longest-lasting storm of the 1992 Pacific typhoon season.  It formed on November 14 near the International Date Line from a monsoon trough, which also spawned two other systems.  Typhoon Gay later moved through the Marshall Islands as an intensifying typhoon, and after passing through the country it reached its peak intensity over open waters.  The Joint Typhoon Warning Center (JTWC) estimated peak winds of 295 km/h (185 mph) and a minimum barometric pressure of 872 mb .  However, the Japan Meteorological Agency (JMA), which is the official warning center in the western Pacific, estimated winds of 205 km/h (125 mph), with a pressure of 900 mbar .  Gay weakened rapidly after peaking because of interaction with another typhoon, and it struck Guam with winds of 160 km/h (100 mph) on November 23.  The typhoon briefly re-intensified before weakening and becoming extratropical south of Japan on November 30.

Typhoon Shanshan (2006): Typhoon Shanshan, known in the Philippines as Typhoon Luis, was a strong typhoon that affected parts of East Asia in late September 2006.  The 13th named storm of the 2006 Pacific typhoon season, Typhoon Shanshan was also the seventh typhoon of the year operationally recognised by the Japan Meteorological Agency.  In post-operational analysis Shanshan became the eighth typhoon of the year when Typhoon Maria was added to the list.  The Joint Typhoon Warning Center considered Shanshan the 13th tropical storm and eighth typhoon of the season, a Category 4-equivalent typhoon in terms of 1-minute average wind speed.  The name "Shanshan" was submitted to the naming list by Hong Kong and is a girls' given name.

Typhoon Dot (1985): Typhoon Dot, known in the Philippines as Typhoon Saling, was the strongest storm of the 1985 season.  Dot originated from a small area of thunderstorm activity in early to mid October.  The system was first classified on October 11, and steadily intensified over the next few days.  Dot attained typhoon strength on October 15, and subsequently entered a period of explosive deepening, which was not anticipated by forecasters.  The next day the intensification rate slowed, but that evening, Dot attained its maximum intensify.  A steady weakening trend began on October 17, though the system maintained typhoon intensity through the passage of the Philippines.  After entering the South China Sea late on October 18, Dot briefly re-intensified, only to weaken as it approached Vietnam.  On October 21, Dot struck Vietnam while still a typhoon, but dissipated the next day over the high terrain of the nation.

1985 Pacific typhoon season: The 1985 Pacific typhoon season has no official bounds; it ran year-round in 1985, but most tropical cyclones tend to form in the northwestern Pacific Ocean between May and November.  These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean.  Tropical Storms formed in the entire west pacific basin were assigned a name by the Joint Typhoon Warning Center.  Tropical depressions that enter or form in the Philippine area of responsibility are assigned a name by the Philippine Atmospheric, Geophysical and Astronomical Services Administration or PAGASA.  This can often result in the same storm having two names.

Typhoon Nuri (2008): Typhoon Nuri, known in the Philippines as Typhoon Karen, was the 12th named storm and the seventh typhoon that was recognised by the Japan Meteorological Agency.  The Joint Typhoon Warning Center recognised it as the 13th tropical depression, the 12th tropical storm and the 8th typhoon of the 2008 Pacific typhoon season.  The name Nuri was submitted to the World Meteorological Organisation's Typhoon Committee by Malaysia in 2003 after the name Rusa was retired in 2002.  The name Nuri is Malay for a blue crowned parroquet, a type of parrot.  The name Karen was assigned by PAGASA to a tropical depression for the second time, the other time being in 2004 to Typhoon Rananim.

Typhoon Omar: Typhoon Omar of 1992, known in the Philippines as Typhoon Lusing, was the strongest and costliest typhoon to strike Guam since Typhoon Pamela in 1976.  The cyclone formed on August 23 from the monsoon trough across the western Pacific Ocean.  Moving westward, Omar slowly intensified into a tropical storm, although another tropical cyclone nearby initially impeded further strengthening.  After the two storms became more distant, Omar quickly strengthened into a powerful typhoon.  On August 28, it made landfall on Guam with winds of 195 km/h (120 mph).  The typhoon reached its peak intensity the next day, with estimated 1‑minute winds of 240 km/h (150 mph), making it a "super typhoon" according to the Joint Typhoon Warning Center (JTWC).  Omar weakened significantly before striking eastern Taiwan on September 4, proceeding into eastern China the next day and dissipating on September 9.

Typhoon Dot (1989): Typhoon Dot, known in the Philippines as Typhoon Kuring, was one of several tropical cyclones to impact southern China and northern Vietnam during the 1989 Pacific typhoon season.  Originating from a tropical disturbance near Palau on June 4, Dot tracked west-northwestward towards the Philippines.  Crossing the country on June 6, the system moved over the South China Sea and attained typhoon status.  Late on June 8, Dot reached its peak intensity with winds estimated at 185 km/h (115 mph).  The system weakened slightly the next day before making landfall in Hainan Island.  A weakened storm then entered the Gulf of Tonkin before striking northern Vietnam and dissipating on June 12.

Typhoon Saomai: Typhoon Saomai, known in the Philippines as Typhoon Juan, was considered the most powerful typhoon on record to strike the east coast of the People's Republic of China.  It was the eighth tropical storm, fifth typhoon, and third super typhoon of the 2006 Pacific typhoon season recognized by the Joint Typhoon Warning Center.  According to the Japan Meteorological Agency, Saomai was the seventh tropical storm and fifth typhoon of the season.  The name "Saomai" was submitted by Vietnam, and is from the Vietnamese word for "morning star" ("sao Mai"), a reference to the planet Venus.
