Kuumuste

Kuumuste is a term used in Estonian climatology and public discourse to describe episodes of unusually high temperatures that persist for multiple days. Derived from kuumus meaning heat, it is used to refer to heat waves and related extreme warmth in weather forecasts, climate reports, and public health advisories in the Baltic region.

Definition and scope: A kuumuste event typically combines a temperature threshold with duration and sometimes elevated nighttime temperatures. Definitions vary by region and institution; common criteria involve daily maximum temperatures exceeding a long-term threshold or percentile for two to three consecutive days, and may also consider heat index or nighttime lows.

Measurement and data: Identification relies on meteorological station data, regional climate datasets, and reanalysis products. National weather services issue alerts during kuumuste periods, and researchers study frequency, intensity, and trends using historical records.

Impacts and response: Kuumuste events pose health risks, particularly for the elderly, children, and outdoor workers; they increase energy demand and strain water resources; agriculture can suffer from heat stress. Policy responses include heat-health warning systems, urban cooling measures, public education, and climate-resilience planning.

Regional context: In Estonia and the Baltic region, kuumuste analysis is part of climate change impact assessment by institutions such as Ilmateenistus and universities, contributing to adaptation strategies.
