Abstract. Assessing the role of physical processes in stratosphere under climate change has been one hottest topics over past few decades. However, due to limitations detection techniques, stratospheric disturbance information from situ observations is still relatively scarce.

Abstract Extreme events have become more frequent in the Northern Hemisphere mid‐latitudes recent decades, hugely impacting ecosystem and society. The quasi‐resonance amplification (QRA) of planetary waves is considered one dynamic mechanisms leading to extreme weather. However, specific impact resonant caused by QRA on surface heat extremes still an open issue. Here we show that closely related double jets, accompanied enhancement atmospheric blocking weakening wave escaping into...
