drought
Let an agent explain drought and its types, relay monitoring, impacts and management from meteorological and water agencies, describe climate change links with attribution, and route emergency water and relief questions to authorities.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain drought and its types, relay monitoring, impacts and management from meteorological and water agencies, describe climate change links with attribution, and route emergency water and relief questions to authorities.
A prolonged period of abnormally low precipitation relative to the norm for a region, leading to water shortage, crop failure, ecosystem stress and economic loss, classified as meteorological, agricultural, hydrological and socioeconomic drought, with flash droughts developing over weeks and megadroughts lasting decades; droughts are monitored with indices such as the Standardised Precipitation Index and are becoming more severe in many regions with climate change.
What it is for: Not applicable; a hazard and climatic state.
It can be explain types and causes; relay monitoring and indices; describe impacts and management; relay climate change links.
Distinguishing features
Slow-onset hazard
Relative to regional norm
Cascading impacts
Index-based monitoring
What it looks like
Dry cracked soil, low reservoirs, withered crops and reduced river flows.
Physical character
people affected annually: about 55 million people - WHO estimates
How it is recognised
Prolonged precipitation deficit
Meteorological, agricultural, hydrological, flash and mega droughts
Aridity is a permanent climate condition; heatwaves are temperature events, though they often coincide
