---@field wind ac.WindParams
---@field transition number @From 0 to 1 (if you’re doing linear transition, better to apply `math.smoothstep()` function to this value).
---@field humidity number @From 0 to 1, 1 for 100% humidity.
---@field pressure number @Pressure In pascals.
---@field variableA number @Custom value for extra data to exchange between controller and implementation (please remember that controller can be swapped with a different one).
---@field variableB number @Custom value for extra data to exchange between controller and implementation (please remember that controller can be swapped with a different one).
---@field variableC number @Custom value for extra data to exchange between controller and implementation (please remember that controller can be swapped with a different one).
---@field rainIntensity number @From 0 to 1, 0.5 for a good heavy-ish rain, everything above is for more absurd thunderstorms.
---@field rainWetness number @From 0 to 1, quickly goes to 1 as rain starts pouring, quickly goes to 0 when rain stops.
---@field rainWater number @Amount of puddles, should slowly move towards rainIntensity value.
