Circulation Conditions’ Effect on the Occurrence of Heat Waves in Western and Southwestern Europe
This article aims to describe the occurrence of heat waves in Western and Southwestern Europe in the period 1976–2015 and determining pressure patterns that cause a persistence of hot days. A hot day was defined as a day on which the daily maximum air temperature was higher than the 95th annual perc...
