Arctic blast
Meaning
An Arctic blast describes the sudden, rapid influx of extremely cold air originating from the polar regions, causing a dramatic drop in temperatures.
Origin
The phrase "Arctic blast" isn't ancient, born in the age of poetic metaphor. Instead, it emerged as a stark, descriptive label in the era of modern meteorology and widespread weather reporting. As the scientific understanding of global air currents advanced, and media outlets sought vivid language to convey serious weather events, the term perfectly encapsulated the raw, undeniable reality of frigid air masses descending from the Arctic Circle. It paints a clear picture: a sudden, powerful "blast" of cold, originating from the Earth's frozen northern reaches, making it a staple in warnings and forecasts whenever polar air decided to pay a harsh visit to warmer latitudes.
Examples
- Residents braced for the Arctic blast, preparing for record low temperatures and heavy snowfall.
