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 katabatic winds, relay mechanism, types, named local winds and hazards from meteorology sources, describe the named winds, route severe wind warnings, and distinguish katabatic winds from anabatic upslope winds, foehn winds, gap winds and general prevailing winds.

A wind that blows down a slope under gravity as dense, cooler air drains downhill, ranging from gentle mountain and valley breezes to violent cold outbursts; forms include foehn-type warming winds and cold varieties, and the registry aliases name Japanese local downslope winds called oroshi, such as the Ibuki, Yatsugatake, Hira and Yamaji winds, the karakkaze dry winter wind, and the Bohemian Wind of Central Europe, which are named local winds. Extreme katabatic winds, as in Antarctica, can reach very high speeds and pose hazards, so weather warnings should be followed.

What it is for: Local downslope winds driven by gravity.

It can be explain mechanism; relay types; describe named local winds; route severe wind warnings.

Distinguishing features

Downslope flow

Gravity-driven

Local names

Can be extreme

What it looks like

Not a visible object; felt as downhill winds, sometimes with dust or drifting snow.

Physical character

Antarctic katabatic speeds: can exceed 300 km/h in places note - as reported

driver: gravity drainage of dense air note

registry parent: fall wind note

How it is recognised

Downslope gravity-driven wind

Ibuki oroshi, Yatsugatake oroshi, Hira oroshi, Bohemian Wind, karakkaze, Yamaji-kaze

Anabatic winds blow upslope; foehn winds are warm and dry lee winds; gap winds funnel through passes; prevailing winds are large-scale
