What it is Filled

Water falling in drops from vapour condensed in the atmosphere; intensity ranges from light rain to downpours and cloudbursts.

Why it exists Filled

Let an agent handle rain by amount, intensity, forecast and impacts, with official warnings first for heavy rain.

Distinguishing features Filled

  • Liquid precipitation
  • Measured in mm
  • Intensity drives flood risk
  • Drizzle has smaller drops

What robots and AI may and may not do Filled

Must not

  • Present its own rain estimate as an official warning.
  • Send people or vehicles through flooded roads or fords.
  • Operate drains or gates contrary to applicable flood management rules or instructions from the responsible authority.

Only with a human decision

  • Issuing or advising action on a flood warning requires human judgment.

May

  • Measure and report rainfall from calibrated gauges or radar.
  • Relay official flood and heavy-rain warnings to people affected.

Moral aspects Filled

  • Heavy rain and floods hit poorer and low-lying communities hardest.

Who is affected

  • People in flood-prone areas
  • Farmers and growers

Owners Filled

Steward

Nobody owns rain; national weather services keep the authoritative records.

Master systems

  • National meteorological rainfall archives

What else AI and robots need to interact with it Filled

Identity and identifiers required Filled

  • Vercy registry: vr.tr.rain
  • Open English WordNet: oewn-11521799-n

Direct properties required Filled

  • heavy rain rate: over about 7.6 mm/h - common threshold
  • drop diameter: 0.5-5 mm

Recognition required Filled

  • Rain gauge readings in mm
  • Intensity: light, moderate, heavy
  • Waterspouts are a different phenomenon
  • Falling drops, wet surfaces, puddles and grey skies.

Capabilities and actions required Filled

  • forecast and measure it
  • harvest rainwater
  • prepare for heavy rain
  • manage drainage

Hazards and failure modes required Filled

  • Flash floods
  • Driving on flooded roads
  • Landslides after intense rain

Standards and interfaces required Filled

  • WMO observation standards
  • National weather warning systems

Context of use required Filled

  • Rain supplies fresh water to land, rivers and crops; heavy rain is a hazard.
  • drizzle
  • showers
  • steady rain
  • downpours and cloudbursts
  • freezing rain
