Heat Wave - English Definition & Meaning

Definition

A heat wave is a prolonged period of excessively hot weather, which may be accompanied by high humidity. ☀️🥵 It typically lasts for several days and can pose significant health risks. Heat waves are caused by stagnant high-pressure weather systems that trap warm air. These events are becoming more frequent and intense due to climate change. It's crucial to stay hydrated and seek cooler environments during a heat wave. Think of it as nature turning up the thermostat way too high for too long!

Etymology

The combination of 'heat' (thermal energy) and 'wave' (referring to a surge or extended period) effectively conveys the idea of a sustained hot spell. Its usage has become more common as climate change intensifies heat waves worldwide.
