Three tropical cyclones formed in March (most active since 1967,) one in May, three in June, four in July, five in August, six in September, four in October, one in November, and one in December.
Sixteen tropical cyclones made landfall, with eight moving through the Philippines, four striking China, three impacting Vietnam, and three crossing Japan.
Nelson formed soon after Mamie, becoming the first typhoon of the season which subsequently moved westward through the southern Philippines before dissipating shy of Vietnam in late March.
Tess became the first tropical cyclone of the season to form in the South China Sea during late June, weakening before reaching Taiwan in early July.
The Japanese Meteorological Agency states that Val was a continuation of Tess, which moved east-northeast from Taiwan to the south of Japan in early July.
Winona moved west-northwest through the northern Philippines across Hainan Island into southern China before dissipating in mid July.
Faye wandered aimlessly between the central Philippines and Taiwan during late August and early September, steered partially by Gordon to its east-northeast.
Roger was the last tropical cyclone of the season, and it moved northward along the northeast side of the Philippines in mid December before dissipating southeast of Taiwan.
Midday on March 24, Mamie made landfall in Nha Trang[5] and subsequently weakened rapidly inland over mountainous terrain.
[8] The Philippine province of Surigao del Sur bore the brunt of the tropical storm,[9] and 117 people died throughout the country,[10] while eight others were injured.
Moving northwest due to significant cyclogenesis offshore Japan, a circulation center developed within this convective cluster over the next few days.
[21] Typhoon Pat became the lone tropical cyclone in the western Pacific basin during the two-month interval between Odessa's dissipation and the formation of Ruby.
Moving westward until the afternoon of May 18, Pat abruptly changed course to the north through a break in the subtropical ridge parallel and close to the Philippines.
[26] The Japanese Meteorological Agency states that Val was a continuation of Tess, which moved east-northeast from Taiwan to the south of Japan in early July.
Observations from Yap late on July 12 verified the existence of a developing low-level center, and it was upgraded to a tropical depression at this time.
Cooler water temperatures and vertical wind shear weakened Cecil as it continued northward, and as a 35 knots (65 km/h) tropical storm, it hit North Korea on August 14.
[1] Recurving to the northeast, Faye continued weakening due to vertical wind shear from Ellis, with dissipation as a tropical cyclone occurring on the afternoon of August 27.
Weakening began anew due to outflow from Typhoon Gordon, and the system became a tropical storm once more on the early morning of August 30.
Weakening back into a tropical storm due to land interaction with Hai-nan and mainland China, the system made landfall about 205 kilometres (127 mi) northeast of Hanoi, then rapidly dissipated as it moved inland.
[50] Moreover, the storm also uprooted trees, downed power and telephone lines, triggered landslides and forced the cancellation of several domestic airline flights on Thursday.
On September 9, Judy appears to have ingested dry air from a nearly tropical upper tropospheric cyclone, as its central eye feature expanded significantly.
When the 70 knots (130 km/h) Typhoon Judy hit southeastern Japan on September 12, its torrential rains left 25 dead and causing moderate damage.
Ken made landfall upon Shikoku early on September 25, and moved onward into the Sea of Japan where it evolved into an extratropical cyclone.
The fourth typhoon of the season to strike Japan, Ken brought winds as high as 114 knots (211 km/h) and rainfall of 221 millimetres (8.7 in) within a six-hour period to Shikoku.
[1] Forming in proximity to the tropical upper tropospheric trough (TUTT), its initial disturbance was first spotted as a weak band of convection near the International Date Line in the subtropics on September 13.
In fact, Ken's outflow kept the thunderstorm activity significantly removed from the depression's low level center for its entire existence.
The cyclone could not develop into a deep system due to the persistent wind shear as it began to round the western periphery of the subtropical ridge.
Weakening back into a tropical depression, Owen eventually dissipated in the warm sector of an approaching extratropical cyclone late on October 27 after tracking over 6,600 kilometres (4,100 mi).
Upper-level outflow from Pamela was leading to moderate to strong vertical wind shear over the disturbance, explaining its slow development.
This table will list all the storms that developed in the northwestern Pacific Ocean west of the International Date Line and north of the equator during 1982.
