Lämpöaallost

Lämpöaallost, also known as a heatwave, is a prolonged period of abnormally hot weather. Typically, it is defined by temperatures that are significantly higher than the average for a particular region and season, often accompanied by high humidity. The duration of a heatwave can vary, lasting from a few days to several weeks.

Heatwaves can have significant impacts on both human health and the environment. For humans, prolonged exposure to extreme heat can lead to heat-related illnesses such as heat exhaustion and heatstroke, which can be life-threatening. Vulnerable populations, including the elderly, young children, and individuals with pre-existing health conditions, are particularly at risk.

Environmentally, heatwaves can exacerbate drought conditions, increase the risk of wildfires, and negatively affect agricultural yields. Water resources can become strained due to increased evaporation and demand for irrigation and cooling. Ecosystems can also suffer, with potential impacts on plant and animal life.

The frequency and intensity of heatwaves are projected to increase in many parts of the world due to climate change. Understanding and preparing for heatwaves is crucial for mitigating their adverse effects. This includes public health measures, urban planning strategies to reduce heat island effects, and water management adaptations.
