2023–2024 El Niño Event
The 2023–2024 El Niño was regarded as the fifth-most powerful El Niño–Southern Oscillation event in recorded history, resulting in widespread droughts, flooding and other natural disasters across the globe. The onset was declared on 4 July 2023 by the World Meteorological Organization (WMO) It was estimated that the most significant meteorological effects would occur between November 2023 and April 2024 and their characteristics would be determined depending on each territory on the planet, within which droughts, heavy rains, wildfires, heat waves, tropical cyclones, flooding and changes in wind patterns occurred. These events have already negatively affected the economic activities of agriculture and fishing, generating shortages and rising prices of food—especially rice, palm oil, sugar cane, soybeans and corn—and, therefore, an increase in food insecurity of the most vulnerable populations.

El Niño–Southern Oscillation
El Niño–Southern Oscillation (ENSO) is a global climate phenomenon that emerges from variation in winds and sea surface temperatures over the tropical Pacific Ocean. Those variations have an irregular pattern but do have some semblance of cycles. The occurrence of ENSO is not predictable. It affects the climate of much of the tropics and subtropics, and has links (Teleconnection, teleconnections) to higher-latitude regions of the world. The warming phase of the sea surface temperature is known as "El Niño" and the cooling phase as "La Niña". The Southern Oscillation is the accompanying atmospheric oscillation, which is coupled with the sea temperature change. El Niño is associated with higher than normal air sea level pressure over Indonesia, Australia and across the Indian Ocean to the Atlantic Ocean, Atlantic. La Niña has roughly the reverse pattern: high pressure over the central and eastern Pacific and lower pressure through much of the rest of the tropics and subtrop ...

International Date Line
The International Date Line (IDL) is the line extending between the South and North Poles that is the boundary between one calendar day and the next. It passes through the Pacific Ocean, roughly following the 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 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 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. People traveling eastward must set their clocks: *Forward by one hour for e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Accumulated Cyclone Energy
Accumulated cyclone energy (ACE) is a metric used to compare overall activity of tropical cyclones, utilizing the available records of windspeeds at six-hour intervals to synthesize storm duration and strength into a single index value. The ACE index may refer to a single storm or to groups of storms such as those within a particular month, a full season or combined seasons. It is calculated by summing the square of tropical cyclones' maximum sustained winds, as recorded every six hours, but only for windspeeds of at least tropical storm strength (≥ 34 kn; 63 km/h; 39 mph); the resulting figure is divided by 10,000 to place it on a more manageable scale. The calculation originated as the Hurricane Destruction Potential (HDP) index, which sums the squares of tropical cyclones' maximum sustained winds while at hurricane strength, at least 64 knots (≥ 119 km/h; 74 mph) at six-hour recorded intervals across an entire season. The HDP index was later modified ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2023 Pacific Hurricane Season
The 2023 Pacific hurricane season was an active and highly destructive Pacific hurricane season. In the Eastern Pacific basin (east of 140°W), 17 named storms formed; 10 of those became hurricanes, of which 8 strengthened into major hurricanesdouble the seasonal average. In the Central Pacific basin (between 140°W and the International Date Line), no tropical cyclones formed for the fourth consecutive season, though four entered into the basin from the east. Collectively, the season had an above-normal accumulated cyclone energy (ACE) value of approximately 168 units. This season saw the return of El Niño and its associated warmer sea surface temperatures in the basin, which fueled the rapid intensification of several powerful storms. It officially began on May 15, 2023 in the Eastern Pacific, and on June 1 in the Central; both ended on November 30. These dates, adopted by convention, historically describe the period in each year when most t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1933 Atlantic Hurricane Season
The 1933 Atlantic hurricane season is the most active Atlantic hurricane season on record in terms of accumulated cyclone energy (ACE), with a total of 259. It also set a record for Tropical cyclone naming, nameable tropical storms in a single season, 20, which stood until 2005 Atlantic hurricane season, 2005, when there were 28 storms. The season ran for six months of 1933, with Tropical cyclogenesis, tropical cyclone development occurring as early as May and as late as November. A system was active for all but 13 days from June 28 to October 7. Because technologies such as Earth observation satellites were not available until the 1960s, historical data on tropical cyclones from the early 20th century is often incomplete. Tropical cyclones that did not approach populated areas or shipping lanes, especially if they were relatively weak and of short duration, may have remained undetected. Compensating for the lack of comprehensive observation and the limited t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Palm Beach Post
''The Palm Beach Post'' is an American daily newspaper serving Palm Beach County in South Florida, and parts of the Treasure Coast. On March 18, 2018, in a deal worth US$42.35 million, ''The Palm Beach Post'' and '' The Palm Beach Daily News'' were purchased by New Yorkbased New Media Investment Group Inc., which has ever since owned and operated ''The Palm Beach Post'' and all circulations and associated digital media sources. History ''The Palm Beach Post'' began as ''The Palm Beach County'', a weekly newspaper established in 1910. On January 5, 1916, the weekly became a daily, morning publication known as ''The Palm Beach Post''. In 1934, the Palm Beach businessman Edward R. Bradley bought ''The Palm Beach Post'' and ''The Palm Beach Times'', which published daily in the afternoon. In 1947, both were purchased by the longtime resident John Holliday Perry Sr., who owned a Florida newspaper chain of six dailies and 15 weeklies. In 1948, Perry purchased both the ''Palm Beach ...

2023 Atlantic Hurricane Season
The 2023 Atlantic hurricane season was the fourth-most active Atlantic hurricane season on record with 20 tropical cyclone naming, named storms forming, tied with 1933 Atlantic hurricane season, 1933. Among them, 7 became hurricanes, with 3 reaching major hurricane strength. The season also had an abovenormal accumulated cyclone energy (ACE) rating of 139, despite the presence of the 2023–24 El Niño event, which typically results in less activity, and had the most storms for an El Niño year on record, largely due to record-warm sea surface temperatures across the Atlantic. The season officially began on June 1 and ended on November 30. These dates, adopted by convention, historically describe the period in each year when most tropical cyclogenesis occurs in the Atlantic. However, the formation of Subtropical cyclone, subtropical or tropical cyclones is possible at any time of the year, as demonstrated by the formation of a subtropical storm ...

1997–98 El Niño Event
The 1997–1998 El Niño was regarded as one of the most powerful El Niño–Southern Oscillation events in recorded history, resulting in widespread droughts, flooding and other natural disasters across the globe. It caused an estimated 16% of the world's reef systems to die, and temporarily warmed air temperature by compared to the usual increase of associated with El Niño events. The costs of the event were considerable, leading to global economic losses of US$5.7 trillion within five years. It led to a severe outbreak of Rift Valley fever after extreme rainfall in north-eastern Kenya and southern Somalia. It also led to record rainfalls in California during the water season of 1997–98, one of Indonesia's worst droughts on record, and contributed to the worst tornado outbreak in the history of the state of Florida. 1998 ultimately became the warmest year in recorded history (up until then).

1982–83 El Niño Event
The 1982–1983 El Niño event was one of the strongest El Niño events since records were kept. It led to droughts in Indonesia and Australia, widespread flooding across the southern United States, lack of snow in the northern United States, and an anomalously warm winter across much of the mid-latitude regions of North America and Eurasia. The estimated global economic impact was over US$8 billion, though more recent work has upward revised this number to be $4.1 trillion. This El Niño event also led to an abnormal number of hurricanes in the Pacific Ocean during this time span; the strongest hurricane up to 1983 hit Hawaii during the event. Meteorological progression Due to a variety of reasons, ranging from the lack of knowledge among the general public regarding El Niño events to the fact that a volcanic eruption in Mexico from El Chichón distracted many scientists from noticing the telltale signs, this event escaped the notice of the scientific world until 1983.

Pre-industrial Society
Pre-industrial society refers to social attributes and forms of political and cultural organization that were prevalent before the advent of the Industrial Revolution, which occurred from 1750 to 1850. ''Pre-industrial'' refers to a time before there were machines and tools to help perform tasks ''en masse''. Pre-industrial civilization dates back to centuries ago, but the main era known as the pre-industrial society occurred right before the industrial society. Pre-Industrial societies vary from region to region depending on the culture of a given area or history of social and political life. Europe was known for its feudal system and the Italian Renaissance. The term "pre-industrial" is also used as a benchmark for environmental conditions before the development of industrial society: for example, the Paris Agreement, adopted in Paris on 12 December, 2015 and in force from 4 November, 2016, "aims to limit global warming to well below 2, preferably to 1.5 degrees celsius, ...
