five seasons=1975, 1976, 1977, 1978, 1979The 1977 Pacific typhoon season has no official bounds; it ran year-round in1977 , but mosttropical cyclones tend to form in the northwesternPacific Ocean between June and December. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwesternPacific Ocean .The scope of this article is limited to the Pacific Ocean, north of the equator and west of the
international date line . Storms that form east of the date line and north of the equator are called hurricanes; see1977 Pacific hurricane season . Tropical Storms formed in the entire west pacific basin were assigned a name by theJoint Typhoon Warning Center . Tropical depressions in this basin have the "W" suffix added to their number. Tropical depressions that enter or form in the Philippine area of responsibility are assigned a name by thePhilippine Atmospheric, Geophysical and Astronomical Services Administration or PAGASA. This can often result in the same storm having two names.torms
21 tropical depressions formed this year in the Western Pacific, of which 19 became tropical storms. 11 storms reached typhoon intensity, of which 1 reached super typhoon strength. [https://metocph.nmci.navy.mil/jtwc/atcr/1977atcr/pdf/1977.html 1977 ATCR TABLE OF CONTENTS ] ]

Dissipated=July 26
1-min winds=85
Pressure=957A tropical disturbance east of thePhilippines organized into a tropical depression onJuly 21 . It moved to the northwest, strengthening into a tropical storm later that day and into a typhoon on the 22nd. After passing northern Luzon Thelma turned to the north, where it reached a peak intensity of 95 mph winds. The typhoon hit southernTaiwan on the 25th, crossed the island, and dissipated over southeasternChina on the 26th. Though not a particularly strong storm, Thelma brought strong wind gusts and heavy rain, claiming more than 30 lives and bringing damage and destruction not seen to the island for over 80 years.Typhoon Vera

Pressure=926Just 6 days after Thelma hit Taiwan, another typhoon was brewing to its east. Typhoon Vera, which developed onJuly 28 , hit eastern Taiwan on the 31st as a 130 mph typhoon. It continued westward, and dissipated over southeastern China. The storm caused 25 additional fatalities to the island, with vast amounts of crop and property damage occurring.Tropical Storm Wanda

Formed=September 1
Dissipated=September 11
1-min winds=130
Pressure=906OnSeptember 2 , Tropical Depression 10 developed well east of the Philippines. Later that day, it reached tropical storm status, and Babe continued to the west, threatening the central Philippines. A break in the subtropical ridge forced Babe northward, where favorable conditions aloft allowed Babe to rapidly intensify, first to a typhoon on the 6th, then to a super typhoon on the 8th. With a northwest movement, the typhoon-flogged Taiwan was again threatened, but Babe turned to the northeast, hitting Okinoerabu Island,Kagoshima . NowJapan was threatened, and full precautions were put in place. Like most of its lifetime, though, Babe changed course, and turned to the northwest in response to the building of the ridge to Babe's northeast. There, unfavorable conditions weakened Babe to a minimal typhoon as it hit nearShanghai, China on the 10th. Babe caused 16 casualties, mostly from shipping, and minor to moderate damage on its path. Those statistics would have been higher if it continued in any one direction of its lifetime.Tropical Storm Carla

Basin=WPac
Formed=September 13
Dissipated=September 23
1-min winds=75
Pressure=964The monsoon trough spawned a tropical storm onSeptember 14 northeast of the northern Philippines. The previous typhoon brought the trough more northward, hence the unusually high latitude for a monsoon storm. Strong high pressure to Dinah's northwest forced the storm to the southwest, where it crossed northern Luzon on the 15th and 16th. Weak steering currents in the South China Sea allowed Dinah to drift, first then to the northeast then back to the west-southwest. Generally favorable conditions allowed Dinah to reach typhoon strength on the 19th, but a developing tropical storm to its northeast caused it to weaken. The building of the subtropical ridge forced Dinah to the southwest, where it hit southernVietnam on the 23rd as a tropical depression. The remnants turned northward, crossed the Gulf of Tonkin, and dissipated over China on the 27th. Dinah brought heavy rain and flooding to Luzon, causing 15 deaths and moderate damage.Tropical Storm Emma
