EXPOSED
Routine forecast production — the modal task — is already the most automated frontier in science: numerical weather prediction plus ML models (GraphCast, AIFS, Pangu) now match or beat human short-range skill, and text/graphic forecast products auto-generate. What survives is the warning decision under ambiguity (issuing a tornado or flash-flood warning at 2 a.m. on conflicting radar signatures), on-air and emergency-manager communication where a named human carries the credibility, and research design in climate and space weather. There is no licensure moat; AMS/NWA certification is preferred, not legally required, so protection rests on accountability and audience trust rather than regulation.
Mixed — a routine tier and a judgment tier. Model output post-processing, gridded forecast editing, and the aviation/marine product cycle are already largely machine-generated, which drags this well below 14 — but the 9 rather than a 5 reflects convective warning decisions, mesoscale discussion writing during a severe outbreak, and satellite/radar instrument calibration and field-campaign design that still require a human reading conflicting data in real time.
Some physical or field component. Most of the work happens at a multi-monitor AWIPS or workstation setup indoors, but the 5 accounts for the minority who launch radiosondes, service ASOS and mesonet sites, deploy mobile radar or dropsonde aircraft during field campaigns, and stand up on a station roof or in a live truck during severe weather.
No licence, no signature requirement. Nothing in the National Weather Service Act or FAA weather-dissemination rules requires a licensed individual to sign a forecast; the AMS Certified Consulting Meteorologist and CBM credentials matter for forensic testimony and broadcast hiring but no statute bars an unlicensed person or a model from issuing the product, and government forecasters are additionally covered by sovereign immunity rather than personal exposure.
Some relationship component. Emergency managers and county officials act on warnings partly because they know the WFO forecaster by name from years of spotter training and conference calls, and broadcast meteorologists are hired for on-air credibility — but the 9 rather than 14 reflects that the majority of consumers of a TAF, a climate reanalysis, or a space-weather alert never learn who produced it.
Meaningful discretion. Deciding at 2 a.m. whether a rotating storm with a marginal velocity couplet warrants a tornado warning — knowing a false alarm erodes future compliance and a miss kills people — plus geomagnetic storm scale calls that ground airline polar routes and utility operators' switching decisions, is genuine unbounded high-stakes discretion; it sits at 13 rather than higher because warning criteria, watch collaboration procedures, and NWS directives constrain the decision space more than in fully open-ended fields.
