Extreme weather 2 - Heatwave


A heat wave is a prolonged period of excessively hot weather, which may be accompanied by high humidity[1]. 
Heatwaves are caused by very hot humid days with very little almost no air movement helping cool things down. As we all know air moves and that’s why we get different temperatures, thus when the air isn’t moving the hot air on a hot day remains the same for several days causing a heat wave. In some places heat waves are a common phenomenon and are therefore not considering extreme weather, in other places (Europe’s extreme heatwave in 2003) heatwaves are classified deadly.
