Estimating Extreme Heat Events in California
Summary
Studying how climate change affects us requires accurately identifying areas hit by extreme weather, like intense heat waves. Usually, researchers estimate these conditions using data from the nearest weather station, but this method can be inaccurate. A new approach has been developed that better tracks Extreme Heat Events by using a more detailed temperature measure. This improved method is much more precise, correctly identifying about one million more Californians affected by severe heat each day between 2017 and 2021, compared to the old way.
Highlights
Our proposed method uses spatial interpolation to accurately estimate EHE boundaries.
The conventional methods rely on absolute temperature and larger spatial scales.
Our method accounts for antecedent climate conditions and composite heat measure.
Our method significantly reduces misclassification of populations impacted by EHEs.
