It's happening more frequently bec of deforestation and over pollution.
# High pressure System :
Trapp warm air in an area occurs due to High pressure system and then heat wave occurs. This phenomena can persist for several days and for that extended period of warm weather.
# Urban Heat Island :
Urban are like Town's, city's are more warmer then rural or country side areas.bec of Structure of concrete and asphalt in urban areas.. and that's create heat wave in urban areas more intense.

# Economic Impact: Health risks, increase in energy use, reduce productivity, cost of dealing with heat wave is increasing significantly.
Long term solution for heat Waves :
# Green space : increase in trees in urban areas will helps to reduce heat wave effect and tree and vegetation will help to release moisture to air which will help to cool down surrounding areas.
# sustainable energy resources : solar power, wind turbine etc type of things will help to reduce greenhouse gas emissions and it will contribute to climate change to reduce heat wave frequency.
# public awareness system : In the era of internet educating the public about heat waves ,how to stay safe is very effective and helps to reduce illness and death from heat waves.
