Weather whiplash: Trends in rapid temperature changes in a warming climate
Abstract Both research and media attention has shown an increasing interest in rapidly changing weather, colloquially termed “weather whiplash” events. This research examines the spatial and seasonal variability of trends in seasonally standardized short‐term temperature ranges across the globe. Tre...

Trends are calculated for three different “range windows”: 7‐day ranges, 1‐day departure, and diurnal (24‐hr) temperature ranges. Results show that globally, over the 70‐year period of record 7‐ and 1‐day ranges are increasing substantially in all seasons, while diurnal trends are only changing (decreasing) significantly in boreal autumn.

Significant decreases in these ranges are noted mostly at the Arctic Ocean confluence with the Pacific and Atlantic Oceans, especially in the Greenland, Iceland, and Norwegian Seas, and more recently, in northeastern Canada. Oceanic trends appear driven by changes in wind speeds, especially in the Southern Hemisphere where increasing open‐ocean winds are nearly ubiquitous. Trends in temperature variability over land are largely inverse of the long‐term changes in cloud cover.

Abstract Both research and media attention has shown an increasing interest in rapidly changing weather, colloquially termed “weather whiplash” events.
