Understanding Winter Extremes: From Temperature Inversions to Historic Cold Records

How do high-pressure systems and temperature inversions conspire to bring bone-chilling temperatures and persistent fog? Join us as we unravel these meteorological mysteries with Lewis Ferris from MetService. We explore how certain regions, like the basins and valleys of Central Otago, are particularly susceptible to these frigid phenomena, and why viticulture and horticulture practitioners must be keenly aware of their local topography. Lewis also sheds light on the chilling effects of temperature inversions, which trap cold air and cloud cover, creating an environment ripe for frost and lingering fog. Hear about the historic cold records in places like Ophir and Ranfurly, and learn how snow can amplify the freeze, plunging temperatures into the double-digit negatives.
