Official Workshop description
DYNAMIC WEATHER
Server-side weather that changes continuously, and stays physically correct.
Arma Reforger gives you four weather states, each with one fixed set of values. This mod replaces those values two times each second, so rain, fog, wind speed and wind direction move all the time and agree with each other: rain waits for the cloud deck, wind leads the front, fog needs calm, clear, cold air.
It drives the sky through the transition queue of the engine, thus the vanilla upcoming-weather panel still works and shows what the mod planned.
It is server-authoritative and puts itself into each mission at the start of the game mode. No mission, prefab or scenario changes. No client download, no addon conflict.
FOR THE PLAYERS
- Five moods in a graph: Clear, Cloudy, Overcast, Rainy and Thunderstorm. The weather keeps a direction and does not oscillate. A front can skip a step, and a storm can break out of a clear afternoon.
- No two storms are equal. Each state gives a range, and the mod rolls the range again at each change.
- Wind that has gusts, a daily cycle and a correct direction. It backs when the weather becomes worse, and it veers when the weather clears.
- Fog from three sources: the haze of heavy rain, radiation fog at night, and sea fog, which forms in daylight and in a wind and which the sun does not clear. An autumn morning can start in steam fog.
- Snow. Below a wet bulb temperature of 0 C the rainy mood asks for a snow sky. Of the vanilla worlds only Kolgujev is cold enough.
- A METAR report in the chat at each new weather period: the wind, the visibility, the precipitation, the cloud, the temperature and the trend.
- Seasons. The date of the scenario controls the temperature and the fog. A November night makes fog frequently, a July night almost never.
- Lightning and a gale in a thunderstorm.
THE CLIMATE OF THE WORLD
The mod reads the latitude and the longitude that the loaded world publishes, and it selects the climate of that place. It ships five of them:
- subpolar-oceanic - Kolgujev only. A cold island: 0 to 12 C, frost, snow, a near-permanent strong wind, storms of Beaufort 11, and skies of its own.
- north-atlantic - Everon and Arland. Open ocean: 8 to 18 C all year, an overcast sky in each season, winter gales of Beaufort 10, sea fog in spring and summer.
- western-europe - 47.5 to 53.5 N, 0.5 to 8.5 E. The maritime plain from the Paris basin to the Rhine: 3.0 C in January, 18.6 C in July, rain in each season and winter fog.
- eastern-europe - 50 to 57.5 N, 21 to 36 E. The continental plain from eastern Poland to western Russia: -5.5 C in January, 19.5 C in July, a dry cold winter and heat cells in summer.
- continental-temperate - any other world. The mod as it was before climates existed.
No vanilla world is in a European box. A terrain that states its own coordinates there gets that climate with no change to this mod, and the climate key can also name one.
A climate decides the temperature, the sea, the dew point, the wind and how probable each mood is in each season. It never decides what a mood IS. The boot log states the climate, the coordinates that selected it, and each key with no effect there.
FOR THE GAME MASTERS
- Game Master, Weather, Automate is the on/off switch. Off releases the rain, the fog, the wind and the lightning in less than one second, and the weather panel then operates normally.
- On again continues from the sky that you left. It does not go back to your storm.
- A state that you select while the automation is on becomes the new start point.
- Move the date or the time of day, and the season, the temperature, the daylight and the fog follow.
- A change of the time acceleration is safe at all times.
FOR THE SERVER ADMINS
The mod writes $profile:DynamicWeather/config.json at the first boot. Each key is optional, a bad file never stops the mod, and a change needs a server restart.
- baseDurationMinutes - the real minutes between the weather changes. 1 to 240, default 40. The setting you change most.
- climate, climateMeanC, climateAmplitudeC, seasonDayOfYearOverride - the climate to build on ("auto" reads the coordinates of the world), the mean temperature and the swing that override it, and a pinned season day.
- temperatureOverrideEnabled, seasonalPatternsEnabled, metarEnabled, metarDelaySeconds, rainVisibleMin, rainTestIntensity, steamFogSeedChance - the switches for the temperature, the seasonal selection and the chat report, the report delay, the rain gate, a rain test aid, and the chance of steam fog.
NOTE: the engine clamps each weather step to 20 game-minutes, which is 5 real minutes at 4x. The mod prints the arithmetic for your world at the start and warns you if your configuration is not possible.

TWO EUROPEAN CLIMATES
The climate table has two climates of the European continent. A world picks one
up on its own, with no key set and no change to this mod, when it publishes a
latitude and a longitude inside the box.
THE TWO CLIMATES
western-europe 47.5 to 53.5 N, 0.5 to 8.5 E
The West European plain from the Paris basin to the Rhine. Maritime: a
January day mean of 3.0 C and a July day mean of 18.6 C, rain in each
season, a light wind, and a narrow winter dew point spread that makes fog.
eastern-europe 50 to 57.5 N, 21 to 36 E
The East European plain from eastern Poland to western Russia.
Continental: a January day mean of -5.5 C and a July day mean of 19.5 C,
the widest day-to-night swing of the table, a dry cold winter, a summer of
heat cells, and few frontal storms.
WHAT A WORLD NEEDS TO PICK ONE UP
1. It publishes coordinates. The climate is keyed on the latitude and the
longitude of the weather manager of the world. A world that publishes
nothing answers 0.0 and 0.0, which is the Gulf of Guinea and is in no box.
2. The point is inside the box above.
3. The climate key is "auto", which is the default. A climate id in the
configuration overrules the coordinates.
The mod reads the pair one time, about three seconds after the world is up, and
never again in the session. The CLIMATE boot line states what it read and what
that selected:
CLIMATE boot | world 'Livonia' lat 52.100 lon 21.000 | resolved
'eastern-europe' (Dfb, Temperate continental / hemiboreal, Eastern Europe) |
source: coordinate box
"source: coordinate box" is the line that says a box selected the climate. A
server that wants one of the two on a world outside the box sets climate to
"western-europe" or "eastern-europe", and the same line then says
"source: config key 'climate'".
