Heatwave
A heatwave is a prolonged period of excessively hot weather, which may be accompanied by high humidity. It typically occurs when a high-pressure system traps warm air in an area, leading to temperatures significantly above average for that region. Heatwaves can last for several days or even weeks, posing health risks, especially to vulnerable populations.
During a heatwave, the risk of heat-related illnesses, such as heat exhaustion and heatstroke, increases. It can also lead to drought conditions, affecting water supply and agriculture. Meteorologists use various criteria, including temperature thresholds, to define and monitor heatwaves, helping communities prepare and respond effectively.
