Climate
Climate is a descriptor used by the IISS to denote average planetary temperate ranges.
- It is not designated in the UWP, but it was semi-regulated by the time of the T5SS using trade codes.

Description / Specifications
Climate and weather are fantastically complicated things affected by dozens upon dozens of factors. With a few exceptions due to fantastically exotic conditions, most planets have a wide variety of climates, biomes, microclimates, ecological zones, and environments. The single-biome world is, for the most part, a very rare fantasy.
- Climatological trade codes represent an equatorial mean climate band average reading.
T5SS Climate Categories Table
The descriptors are as follows:
Climate: | Temperature Range:
(Degrees Celsius) |
T5SS TC: | Orbit: | Lifeforms: | Remarks: |
---|---|---|---|---|---|
Vacuum (none) | Extreme: Almost always cold or frozen. | Va (vacuum)
As (asteroid or planetoid) |
Any | Unconventional Life or Exotic Life
(extremophile) |
Impossible: Habitation is almost always impossible without extensive technology.
|
Frozen (frigid) | Below -30 | Fr (frozen)
Ic (iceworld) |
HZ +2 | Conventional Life (cryomorph) | Nigh Impossible: Habitation is near impossible without technology. |
Very Cold | -30 to -20 | Vc (very cold)
Ic (iceworld) |
HZ +1 | Conventional Life (hypercryophile) | Not Hospitable: Habitation is very difficult. |
Cold | -20 to -5 | Co (cold)
Ic (iceworld) |
HZ +1 | Conventional Life (cryophile or psychrophile) | Unhospitable: Habitation is difficult. |
Chilly | -5 to 5 | Ch (chilly) | (HZ plus) | Conventional Life (normative: mesophile) | Semi-Hospitable: Still marginally habitable.
|
Cool | 5 to 15 | Tu (tundra) (Terra-norm)
Nrm- (cool normal) |
(HZ plus) | Conventional Life (normative: mesophile) | Hospitable: Still habitable.
|
Normal (optimal) | 15 to 25 | Tp (temperate)
Ga (garden or gaia) (Terra-prime) Nrm (normal) (Terra-norm) |
HZ | Conventional Life (normative: mesophile) | Very Hospitable: Very conducive to life. Almost every Garden World or Terra-prime world possess this ideal climate.
|
Warm | 25 to 40 | Wa (warm) (Terra-norm)
Nrm+ (warm normal) |
(HZ neg) | Conventional Life (normative: mesophile) | Hospitable: Still habitable.
|
Tropical | 40 to 50 | Tr (tropical) | (HZ neg) | Conventional Life (normative: mesophile) | Semi-Hospitable: Still marginally habitable. |
Hot | 50 to 60
(122 to 240 F) |
Ho (hot) | HZ -1 | Conventional Life (thermophile) | Unhospitable: Habitation is difficult. |
Very Hot | 60 to 70 | Vh (very hot) | HZ -1 | Conventional Life (hyperthermophile) | Not Hospitable: Habitation is very difficult. |
Inferno (torrid) | 70+ | If (infernal) | HZ -2 | Conventional Life (thermomorph) | Nigh Impossible: Habitation is near impossible without technology.
|
Variable (chimeric) | Extreme: Variable | Lk (locked: satellite or moon)
Tz (twilight zone: mainworld) |
Starward or Any | Unconventional Life or Exotic Life
(extremophile) |
Impossible: Habitation is almost always impossible without extensive technology.
