Climatic normal
The arithmetic average of a climate element computed over a long period, typically used as a baseline to compare current weather patterns.
Также говорят: long-term average, climatological standard, climate baseline
Climatic normals provide a critical benchmark for agricultural planning and risk management. By comparing real-time data against these averages, producers can decide when to initiate sowing or apply crop protection products based on expected temperature and precipitation trends.
A common mistake is treating the normal as a forecast rather than a historical average. Relying solely on these figures without checking near-term meteorological forecasts can lead to poor decision-making regarding irrigation scheduling or harvest timing during anomalous weather events.
