List of cyclones in LEAOR

Overview

Storms that entered the Liverpool England Area of Responsibility for tropical cyclones were named alphabetically, with no yearly lists, by the Met Service. Names were used in sucession, meaning if the names on a list run out, the next list would be used to name further storms. If the last storm for a season was "Jova", "Kevin" would be the next name used. There were 60 names in all; when the 60th named storm had formed, the Greek alphabet would have been used to name storms in the order: Alpha, Beta, Gamma, Delta, Theta, Lambda, Pi and Omega, afterwhich the first name on the list of 60 would be used. Particularly devastating storms had their names struck off the list by the Liverpool England Met Service, and replaced. Names alternated from male to female for the first 42 names, afterwhich they had no set order.

With the latest expansion of the Area of Responsibility, the naming scheme was been altered. While the old 60 names will remain in use, the Meteorological Service Hurricane Prediction Centre requested nations within the new AoR to submit one local name to the naming scheme. The new names run alphabetically in the order of the submitting nation, followed by the old 60, they would repeat, with Greek letters being eliminated.

Officially, hurricane season runs from March 1 to November 1 annually, and from February 14 to December 14 in some areas, although these dates just convetionally delimit the period when most systems are expected to form. Storms can form outside the official season boundaries, however.

Before a depression is recognised, it is usually tagged an "INVEST" storm - an area of low pressure with the potential to strengthen into a cyclone. INVESTs are tracked by the MSHPC's satellite bureau in Kompa Ru, with advisories on potential systems every 12 hours (INVEST tracker).

Unofficial LLIWO TCWC list

In March 2145, the MSHPC appointed the Lox Land Island Weather Observatory as a tropical cyclone warning centre for all cyclones within a 400-km radius of the island, and allowed it to warn on systems and name them as it saw fit, as long as the names did not clash with the official name list. The chosen names were from the Greek and Phoenician alphabets. This list will repeat from "Alpha" as soon as "Daleth" is used. Names are used sequentially. If there are more than 10 storms warned on by the TCWC, the storms would be named backwards, i.e. Storm #11 would be named "Ahpla", storm #12 "Ateb", storm #13 "Ammag", et cetera.

List of storms in new AOR

Below, YYNN designation refers to the year, and the Xth storm of it. Storms are also designated AARR.NAME where AA is the storm number and RR is the section (northeast, northwest, southeast, southwest) of the region it formed in.

• /2139new
• 2140 Heartland cyclone season
• No official storms formed between 2141 and 2144 inclusive, although the MSHPC was in limbo, and storms were reported.

Accumulated Cyclone Energy

ACE is calculated for the whole AOR beginning 2139. However, only the windspeeds from full advisories (intermediate advisories do not count) are taken into account, be they four or 24 hours apart. Winds while any system is outside the AOR do not count. Only winds at above tropical depression strength (35 kt) count. Unit for ACE is 10⁴kt².

Post-storm reports

After every storm, the Met Service Hurricane Prediction Centre reviews their advisories for each storm, summarising them in post-storm reports. Storms may be classified at a higher or lower category, have their maximum winds (and thus ACE value) adjusted, or have landfalls cleared up. Article: AOR Post-storm reports.
