Heat Wave started to claim more and more life each year, even in Europe and USA

prolonged period of excessively hot weather, which may be accompanied by high humidity

If humidity is high people sweat less and body temperature rises rapidly

Cause of Heat wave:High pressure in high altitude

(10,000-25000 ft). Cold air sink down and act dome, capping

atmosphere. And radiated heat get trapped inside dome causing

increasing temperature

Changes in Jet stream main cause of heat waves

Cold arctic air

Warm airjet

Jet streams form in high altitude when cold arctic air meets warm air

Jet streams are fast flowing air current (as fast as 200mph

Hot

Warm air

Ω wave in Jet stream means extreme weather

Ω wave in Jet stream pulled in air from Africa & caused heat wave in Europe in

2015

Ω wave in Jet stream pulled in air from Arctic & caused cold wave in USA in

2014-15

Arctic warming is making Jet

streams weaker and increasing

chances of Ω waves

So,Changes are here
