Tropical cyclone naming

Kalassak: /* South Uqe */ idk lmao

this page will have all the temporary and then eventually official lists of pavalan cyclone basins

== North Uqe ==

The RSMC for this region is the Soleani Cyclone Center in Saelunavvk, Solea. Names are contributed by language family of origin and alternate through the four language families on the Amalthean continent: North Amalthean, Auspik, Serkr-Auspik, and Serkr-Mpáɲara.

quite possibly this region goes to 160W or something

make list of meanings and countries/regions of origin

== Egun & Hac Lake ==

this place needs a name and might be multiple basins (split ganuo and hac areas up? maybe even the shallow sea has its own warning center?)

of all the large tropical lakes the Hac Sea is probably the most promising for cyclogenesis

list: Egosa, Tu'ue, Kea, Suka', A'nis, E'po, Penpa, Sekasa, Hoti, Jrišúnú

list: Turisoa, Aiosa, Ganae, Kalok, Pano'a, Ige'i, I'egeok, Ego, Tukeja', Pňíǧó 

== Central Rift ==

there's water here

cyclones may or may not form here (probably not)

it has no temporary list

== North Forbidden ==

pretty typical basin

is this considered the Northeast Uqe?

this is kind of a fun one that i'm interested to see how it turns out but probably will be highly influenced by sst climatology

== South Uqe ==

what is the region of cyclone formation here? does it go all the way to ivinis? is this area actually pretty dead in general? who knows. it acted very south pacific-like in the wrf simulation but that had earth SSTs

temporary list (probably auspik-ish), probably should have some unuvi-originating names, tana or kahákpi or w/e, auspik colonizer names. perhaps have this list alphabetical... but in what alphabet? alternatively make this one with names contributed by nations

tentatively east of 120E (all the way to ivinis)

== Intertibetia ==

there's a shallow but large lake here, that means it's gonna be hot but its energy easily used up, cyclones might still be able to form here under the right conditions

there's also a rift and ocean south of 30S, so maybe there is some subtropical activity in that area. maybe not because that's all cold polar water, maybe yes cause there's no antarctica in shem

another tropical lake/sea, it's kinda far south but also the hadley cell probably covers it pretty well, it's unfortunately oriented meridionally though so cyclones will be short-lived if at all (since disturbances will only be over water for a short time). could fuel subtropical systems in the southern part

Tropical cyclone scales

2026-10-06T04:16:13Z

Kalassak:

== Preliminary Pavala scale ==

The preliminary Pavala scale is the scale that Kalassak will use to assess the intensity of cyclones in basins without defined cyclone scales. It is based on the Saffir-Simpson hurricane wind speed scale, but the number of categories is adjusted to match the vast majority of [https://en.wikipedia.org/wiki/Tropical_cyclone_scales cyclone scales on Earth]. The changes are as follows:

* Tropical storm is split into two categories at 48 kts (based on JMA scale)
* Categories 1 and 2 are merged into one category with no changes to bounds (every other scale has 3 hurricane-force categories)
* Categories 3 and 4 are merged into one category with no changes to bounds (every other scale has 3 hurricane-force categories)

== North and South Uqe ==

Wind speeds in the North and South Uqe basins are given in kezpíga per úko, rounded to the nearest dozen (the Amalthean number system uses base 12). Conversions to knots are rounded to 5. Measurements are 1-<soleani minute>/144 úko (or approx. 10-minute) averages. add auspik/international units

In the South Uqe, the RSMC is <probably auspik, but it might be north amalthean>, so while the category bounds are the same, their names are different.

information on cyclones in the #mpasvala2026 Earth test simulations

Storms in the simulations are labeled with an alphanumeric identifier composed of a single letter based on the octant of the sphere in which they first develop and an incrementing number for each successive cyclone formation. Each octant will correspond to a letter from A through H, with A for cyclones developing north of the equator between 90°E and 180°, B for cyclones developing north of the equator between 0° and 90°E, and so on, in counterclockwise order such that alphabetical order progresses from east to west in the northern hemisphere and west to east in the southern hemisphere (H designations south of the equator between 90°E and 180°). For example, the first cyclone to develop east of 90°E in the northern hemisphere (roughly corresponding to the West Pacific) will be assigned the identifier A1. Names will be assigned to storms achieving tropical storm status (winds >= 34 kt) based on the next name in the list the storm would have been given based on the simulation start date of August 2, 2024 — ''Carlotta'' in the East Pacific, ''Debby'' in the North Atlantic, ''Asna'' in the North Indian, ''Maria'' in the West Pacific, ''Pita'' in the South Pacific, ''Robyn'' in the Australian region, ''Ancha'' in the Southwest Indian, and ''Biguá'' in the South Atlantic.

information on cyclones in the #mpasvala2026 Earth test simulations

Storms in the simulations are labeled with an alphanumeric identifier composed of a single letter based on the octant of the sphere in which they first develop and an incrementing number for each successive cyclone formation. Each octant will correspond to a letter from A through H, with A for cyclones developing north of the equator between 90°E and 180°, B for cyclones developing north of the equator between 0° and 90°E, and so on, in counterclockwise order such that alphabetical order progresses from east to west in the northern hemisphere and west to east in the southern hemisphere (H designations south of the equator between 90°E and 180°). For example, the first cyclone to develop east of 90°E in the northern hemisphere (roughly corresponding to the West Pacific) will be assigned the identifier A1. Names will be assigned to storms achieving tropical storm status (winds >= 34 kt) based on the next name in the list the storm would have been given based on the simulation start date of August 2, 2024 — ''Carlotta'' in the East Pacific, ''Debby'' in the North Atlantic, ''Asna'' in the North Indian, ''Maria'' in the West Pacific, ''Pita'' in the South Pacific, ''Robyn'' in the Australian region, ''Ancha'' in the Southwest Indian, and ''Biguá'' in the South Atlantic.

== August run, 48 km uniform ==
from the May/June 2026 MPAS Earth simulation for August 2, 2024 through September 2

Five tropical cyclones developed in the West Pacific, though none reached typhoon strength. A single hurricane developed in the North Atlantic from a precursor present at model initialization.
