The 1978 Pacific typhoon season was a very active season that produced 31 tropical storms, 16 typhoons and one intense typhoon. It ran year-round in 1978, but most tropical cyclones tend to form in the northwestern Pacific Ocean between June and December. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean.

The scope of this article is limited to the Pacific Ocean, north of the equator and west of the International Date Line. Tropical storms that formed in the basin were assigned a name by the Joint Typhoon Warning Center while systems that were active in the Philippine area of responsibility were assigned a name by the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA). This often results in the same storm having two names.

Seasonal summary

33 tropical depressions formed this year in the Western Pacific, of which 29 became tropical storms. 15 storms reached typhoon intensity, of which 1 reached super typhoon strength. Many of the storms either remained at sea or failed to do any damage.

Systems

Severe Tropical Storm Nadine

Severe tropical storm (JMA)
Tropical storm (SSHWS)
Duration	January 6 – January 13
Peak intensity	100 km/h (65 mph) (10-min); 970 hPa (mbar)

Nadine stayed at sea and was the first severe tropical storm of the season. It lived at least 1 week.

Typhoon Olive (Atang)

Typhoon (JMA)
Category 2 typhoon (SSHWS)
Duration	April 15 – April 26
Peak intensity	150 km/h (90 mph) (10-min); 955 hPa (mbar)

On 12:00 UTC on April 11, the Joint Typhoon Warning Center (JTWC) began to monitor a surface circulation which had formed within the trough. Five days later, the JTWC issued their first warning on the system as it began coalescing. On April 18, the system entered the Philippine Area of Responsibility, resulting in PAGASA naming the system Atang. Later that day, the system intensified into a tropical storm, resulting in it being named Olive.

Olive would steadily intensify after it entered the South China Sea on April 20, being in an environment with good outflow aloft and warm Sea surface temperatures, resulting in it intensifying into a typhoon on April 22. Olive would recurve due to a break in the subtropical ridge, peaking with sustained winds of 100 mph (160 km/h) the next day. It accelerated to the east-northeast, steadily weakening due to intruding cool and dry air, resulting in the system becoming extratropical early on April 26.

As Olive passed the Philippines, it would affect nearly 370,000 people in the nation, leaving 3,500 homeless. The MV Leyte, a lengthened ship of the Compania Maritima was caught in it, being wrecked in the southwestern portion of Sibuyan Island as she was on a Manila-Cebu voyage. The Hong Kong Observatory would hoist its Stand-By Signal No. 1 for Hong Kong on April 24 as Oliver was at its closest to the island.

Increased convective activity in the monsoon trough was first noticed on satellite data on November 14 about 690 mi (1,110 km) southeast of Truk. On November 16, the disturbance was upgraded to Tropical Depression 33. Based on an improved satellite signature, TD 33 was upgraded to Tropical Storm Viola at 1200 UTC November 17. Viola continued to intensify as the storm moved on a northwestward track. Late on November 19 reconnaissance aircraft confirmed that Viola's surface pressure had fallen to 977 mb; and, that an eye was beginning to form. Early on November 20, Viola was upgraded to a typhoon. Viola then started to rapidly intensify and reached peak intensity on November 21 with winds of 145 mph (233 km/h). Viola recurved away from Luzon on November 22. By the next day, the storm had already weakened to a category 1 and further weakened to a tropical storm. Viola dissipated on November 24.

On the 29th, Winnie reached its peak intensity as severe tropical storm with (10-min) winds of 65 mph (105 km/h). Winnie became extratropical early on November 30.

Tropical Depression Garding

Tropical depression (JMA)
Duration	December 13 – December 19
Peak intensity	55 km/h (35 mph) (10-min); 1004 hPa (mbar)

The last system of the season, Tropical Depression 63W (Garding) was named by PAGASA.

Storm names

During the season 28 named tropical cyclones developed in the Western Pacific and were named by the Joint Typhoon Warning Center, when it was determined that they had become tropical storms. These names were contributed to a revised list from late 1950. However the JTWC changed their naming scheme by the next year, now including both female and male names.

One name, Susan, developed over the Central Pacific and was named from this list. The storm never became a part of the West Pacific basin.

Philippines

The Philippine Atmospheric, Geophysical and Astronomical Services Administration uses its own naming scheme for tropical cyclones in their area of responsibility. PAGASA assigns names to tropical depressions that form within their area of responsibility and any tropical cyclone that might move into their area of responsibility. Should the list of names for a given year prove to be insufficient, names are taken from an auxiliary list, the first 6 of which are published each year before the season starts. Names not retired from this list will be used again in the 1982 season. This is the same list used for the 1974 season. PAGASA uses its own naming scheme that starts in the Filipino alphabet, with names of Filipino female names ending with "ng" (A, B, K, D, etc.). Names that were not assigned/going to use are marked in gray.

Retirement

Due to extreme damages and death toll caused by Typhoon Rita (Kading), PAGASA retired the name Kading in its auxiliary list. The name replaced was Katring.

Season effects

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 1978. It will include their intensity, duration, name, areas affected, deaths, missing persons (in parentheses), and damage totals. Classification and intensity values will be based on estimations conducted by the JMA. All damage figures will be in 1978 USD. Damages and deaths from a storm will include when the storm was a precursor wave or an extratropical low.
