To measure the heat wave index, one of recommendation of the Intergovernmental Panel on Climate Change (IPCC) was to use the heat wave duration index (HWDI). This index has been defined as as the maximum period in each year of at least 5 consecutive days where the maximum temperature is at least 5°C warmer than the daily climatology.
Sep 5, 2024 · Drawing from these, and other, studies we can see a heat wave definition needs to include factors of: (1) intensity or magnitude: based on a tested index or temperature threshold, (2) duration: defining the persistent of an event to be a heat wave, (3) extent: geographic areas impacted and measures of exposure, and possibly (4) severity .
Nov 11, 2021 · The frequency and intensity of extreme events especially heat waves (HW) are growing all around the world which ultimately poses a serious threat to the health of individuals. To quantify the effects of extreme temperature, appropriate information, and the importance of HW and heat index (HI) are carefully discussed for different parts of the world. Varied definitions of the HW and HI formula ...

duration indexes based on two arbitrarily defined constants. The principal weakness of this approach is that it does not yield comparable results for different geographical locations. This paper remedies the current lack of a meteorologically based definition of heat and cold waves and offers a preliminary test ofits performance. Having ...

A Multiscalar Drought Index Sensitive to Global Warming: The Standardized Precipitation Evapotranspiration Index, J. Climate, 23, 1696–718. doi: 10.1175/2009JCLI2909.1 WMO 2012. Standardized Precipitation Index User Guide (7 bis, avenue de la Paix — P.O. Box 2300 — CH 1211 Geneva 2 — Switzerland).
Nov 7, 2019 · A significant heatwave of a duration of 1–2 weeks has affected parts of the United Kingdom in 10–20% of years. The heatwave definition is intended to provide a useful tool for communicating to the government, public and private sectors the forecasts of warm spells, hot spells and heatwaves.
