Possible influences of spring Barents Sea ice shrinking on Chinese heat wave events
Abstract Heat waves have a catastrophic impact on ecosystems, economy, society and human health. Revealing the underlying physical drivers of heat waves is essential for improving extreme event forecasts and disaster prevention capabilities under climate change. Thus, this study provides an analysis...

In particular, the reduced sea ice coupled with NAO strengthens the anomalous eastward SAH and anomalous westward WPSH of their position and intensity especially in 2022 and provides favourable atmospheric circulation patterns for the occurrence of heat waves.
