Typhoon Olive (1978)
Typhoon Olive, known in the Philippines as Typhoon Atang, was a powerful tropical cyclone which affected the Philippines and Taiwan during April 1978. The second named storm and first typhoon of the 1978 Pacific typhoon season, Olive developed from a low-pressure area on April 15. One week later, it would peak as a minimal typhoon with 10-minute sustained winds of 90 mph. After it, it would steadily weaken, being last noted on April 26 Meteorological history In April 1978, the near-equatorial trough steadily tracked northwards, making cyclogenesis more likely to occur. 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 ''Tropical Depression 02W'' as the nascent system began coalescing. On April 18, the system entered the Philippine Area of Responsibility, resulting in the Philippine Atmospheric, Geophysical and Astro ...

1978 Pacific Typhoon Season
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.

Cyclogenesis
Cyclogenesis is the development or strengthening of Cyclonic rotation, cyclonic circulation in the atmosphere (a low-pressure area). Cyclogenesis is an umbrella term for at least three different processes, all of which result in the development of some sort of cyclone, and at any size from the microscale meteorology, microscale to the synoptic scale meteorology, synoptic scale. * Tropical cyclones form due to latent heat driven by significant thunderstorm activity, developing a warm core. * Extratropical cyclones form as waves along weather fronts before occluding later in their life cycle as cold core cyclones. * Mesocyclones form as warm core cyclones over land, and can lead to tornado formation. Waterspouts can also form from mesocyclones, but more often develop from environments of high instability and low vertical wind shear. The process in which an extratropical cyclone undergoes a rapid drop in atmospheric pressure (24 millibars or more) in a 24-hour period is referred to a ...

Joint Typhoon Warning Center
The Joint Typhoon Warning Center (JTWC) is a joint United States Navy – United States Air Force command in Pearl Harbor, Hawaii. The JTWC is responsible for the issuing of tropical cyclone warnings in the North-West Pacific Ocean, South Pacific Ocean, and Indian Ocean for all branches of the U.S. Department of Defense and other U.S. government agencies. Their warnings are intended primarily for the protection of U.S. military ships and aircraft, as well as military installations jointly operated with other countries around the world. Its U.S. Navy components are aligned with the Naval Meteorology and Oceanography Command. History The origins of the Joint Typhoon Warning Center (JTWC) can be traced back to June 1945, when the Fleet Weather Center/Typhoon Tracking Center was established on the island of Guam, after multiple typhoons, including Typhoon Cobra of December 1944 and Typhoon Connie in June 1945, had caused a significant loss of men and ships.

Philippine Area Of Responsibility
The Philippine Area of Responsibility (PAR) is an area in the Northwestern Pacific where PAGASA, the Philippines' national meteorological agency, monitors weather occurrences. Significant weather disturbances, specifically typhoons that enter or develop in the PAR, are given Philippine-specific names. Boundary The area is bounded by six points namely (clockwise): * * * * * * This area encompasses almost all of the land territory of the Philippines, except for the southernmost portions of the province of Tawi-Tawi, and some of the country's claimed islands in the Spratlys. The area also includes the main island of Palau, most of Taiwan, as well as portions of the Malaysian state of Sabah, the Japanese prefecture of Okinawa ( Miyakojima, Tarama, Ishigaki, Taketomi, Yonaguni) and a small patch of land in Brunei ( Brunei–Muara District). Function The establishing decree of PAGASA mandates the weather agency to monitor weather occurrences occurring within the PAR. ...

Leyte Gulf
Leyte Gulf, also known simply as the Leyte, is a gulf in the Eastern Visayan region in the Philippines. The bay is part of the Philippine Sea of the Pacific Ocean, and is bounded by two islands; Samar in the north and Leyte in the west. On the south of the bay is Mindanao Island, separated from Leyte by the Surigao Strait. Dinagat Island partly encloses the gulf to the southeast, and the small Homonhon Island and Suluan Island, sit astride the eastern entrance to the Gulf. It is approximately north-south, and east-west. Several municipalities are situated on the coast of the gulf: Balangiga, Giporlos, Guiuan, Lawaan, Mercedes, Quinapondan and Salcedo. There are also eleven marine reserves in the gulf region. Leyte Gulf was also the scene of the Battle of Leyte Gulf, which extends to Surigao Strait during the Battle of Surigao Strait, the largest naval battle of World War II and started the end of Japanese occupation in the Philippines.

Sea Surface Temperature
Sea surface temperature (or ocean surface temperature) is the ocean temperature, temperature of ocean water close to the surface. The exact meaning of ''surface'' varies in the literature and in practice. It is usually between and below the sea surface. Sea surface temperatures greatly modify air masses in the Atmosphere of Earth, Earth's atmosphere within a short distance of the shore. The thermohaline circulation has a major impact on average sea surface temperature throughout most of the world's oceans. Warm sea surface temperatures can develop and Tropical cyclogenesis, strengthen cyclones over the ocean. Tropical cyclones can also cause a cool wake. This is due to turbulent mixing of the upper of the ocean. Sea surface temperature changes during the day. This is like the air above it, but to a lesser degree. There is less variation in sea surface temperature on breezy days than on calm days. Coastal sea surface temperatures can cause offshore winds to generate upwelling ...

Sibuyan Island
Sibuyan is a crescent-shaped island, the second largest in an archipelago comprising Romblon Province, Philippines. Located in the namesake Sibuyan Sea, it has an area of and has a total population of 62,815, as of the 2020 census. The island has two prominent peaks, the highest is Mount Guiting-Guiting, with an elevation of , followed by Mount Nailog, which is high. The people speak the Sibuyanon dialect of Romblomanon, a Visayan language. Sibuyan has been dubbed by some local and international natural scientists as "the Galápagos of Asia", because it has remained in isolation from the rest of the world since its formation. Never in its geological history has it ever been connected with any part of the Philippine archipelago. Seismic forces pushed up a peak from the Earth's crust, forming a series of smaller peaks and slopes. The peak is Mount Guiting-Guiting (literally means "the saw-toothed mountain", in reference to its jagged ridge). Because of the steep slopes, m ...
