Transcript of Why Heat Wave Occurs and Cause of Extreme Weather (Changes in Jet Strem)
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
