What Causes a Heat Wave?
Heat waves usually form when the hot air is pushed downwards by the high-pressure system created in the atmosphere that traps the heat waves and results in an increase in the surface temperature. This high-pressure system retards rainfall and making already-hot air even hotter. As long as this high-pressure system stays, heat waves also exist.
Heat Wave
In the past few decades, industrialization and modernization have led to deforestation, increasing the surface temperature due to less rainfall and ozone layer depletion. During the summer season, many parts of the world, especially tropical regions faces, heat waves. Heat waves can be hazardous for humans as well as for animals as they can create a drought, and skin issues in humans, and lead to crop depletion as well.
