2019–20 South Pacific Cyclone Season
The 2019–20 South Pacific cyclone season was a slightly above-average season in which tropical cyclones formed within the South Pacific Ocean to the east of 160°E. The season officially ran from November 1, 2019, to April 30, 2020, however a tropical cyclone could form at any time between July 1, 2019, and June 30, 2020, and would count towards the season total. The season began on November 22 with the formation of Tropical Cyclone Rita, which would later become a severe tropical cyclone. The season has been near-average in terms of activity, with 8 tropical cyclones and 4 severe tropical cyclones forming during the season. The season featured Cyclone Harold, the first Category 5 severe tropical cyclone in the basin since Cyclone Gita, and one of the strongest since Cyclone Winston. During the season, tropical cyclones are officially monitored by the Fiji Meteorological Service (FMS), Australian Bureau of Meteorology (BOM) and New Zealand's MetService.

Cyclone Harold
Severe Tropical Cyclone Harold was a very powerful tropical cyclone which caused widespread destruction in the Solomon Islands, Vanuatu, Fiji, and Tonga during April 2020. It was the first Tropical cyclone scales#Australia and Fiji, Category 5 tropical cyclone in 2020. The seventh named storm of the 2019–20 Australian region cyclone season, eighth named storm, and fourth severe tropical cyclone of the 2019–20 South Pacific cyclone season, Harold was first noted as a developing tropical low within a trough of low pressure during April 1, while it was located to the east of Papua New Guinea. Over the next day, the system moved south-eastwards over the Solomon Sea, before it was classified as a tropical cyclone and named Harold by the Australian Bureau of Meteorology. The system moved into the Fiji Meteorological Service, Fiji Meteorological Service's area of responsibility on April 2 and began to explosively intensify by April 3, reaching Category 4 status by April&nb ...

Severe Tropical Cyclone
Tropical cyclones are ranked on one of five tropical cyclone intensity scales, according to their maximum sustained winds and which tropical cyclone basins they are located in. Only a few classifications are used officially by the meteorological agencies monitoring the tropical cyclones, but other scales also exist, such as accumulated cyclone energy, the Power Dissipation Index, the Integrated Kinetic Energy Index, and the Hurricane Severity Index. Tropical cyclones that develop in the Northern Hemisphere are classified by the warning centres on one of three intensity scales. Tropical cyclones or subtropical cyclones that exist within the North Atlantic Ocean or the North-eastern Pacific Ocean are classified as either tropical depressions or tropical storms. Should a system intensify further and become a hurricane, then it will be classified on the Saffir–Simpson hurricane wind scale, and is based on the estimated maximum sustained winds over a 1-minute period.

International Dateline
The International Date Line (IDL) is the line extending between the South Pole, South and North Poles that is the boundary between one calendar day and the next. It passes through the Pacific Ocean, roughly following the 180th meridian, 180.0° line of longitude and deviating to pass around some territories and island groups. Crossing the date line eastbound decreases the date by one day, while crossing the date line westbound increases the date. The line is a Cartography, cartographic convention and is not defined by international law. This has made it difficult for cartographers to agree on its precise course and has allowed countries through whose waters it passes to move it at times for their convenience. Geography Circumnavigating the globe People traveling westward circumnavigation, around the world must set their clocks: *Back by one hour for every 15° of longitude crossed, and *Forward by 24 hours upon crossing the International Date Line.
