Harvora™ model-card brief
Seasonal dryness outlook model card
This model card documents the method, evidence target and limitations for seasonal dryness outlook. No seasonal forecast-skill validation exists at this range, and none is claimed. The surface is historical context for planning conversations — irrigation readiness, water budgets — and says so wherever it appears.
Direct answer
What this supports
Seasonal dryness is a historical tilt on rainfall likelihood, explicitly a climatology read and never a forecast of a specific dry event.
Intended for New Zealand growers, technical partners, lenders and insurers.
Evidence and method
How the signal is formed
Regional rainfall history is conditioned on the ENSO state to produce a seasonal dryness tilt per representative region.
Evidence grade: ESTIMATE
Weather-benchmark measured today; every grower outcome logged in the product feeds the field benchmark it is measured against next.
Boundary
How to read this evidence
No seasonal forecast-skill validation exists at this range, and none is claimed. The surface is historical context for planning conversations — irrigation readiness, water budgets — and says so wherever it appears.
