Topic	Key Facts
Event	Severe heatwave in Europe, temperatures exceeding 42°C (France).
Cause	Omega Block--a high-pressure system forming a stagnant Ω-shaped jet stream pattern.
Mechanism	- Jet stream loops and stalls, halting eastward movement. - High-pressure system compresses air, creating a heat dome. - Blocks rain, prolonging heat and causing droughts or floods elsewhere.
Impact of Climate Change	- Heatwaves now 2-4°C hotter due to global warming. - Arctic warming reduces temperature gradient, weakening jet stream and increasing blocking events.
Regions Affected	France, Spain, Italy, and other parts of Western Europe.
