The 2021 European Heat Wave in the Context of Past Major Heat Waves

open access: yesEarth and Space Science, 2022
The past two decades in Europe have been characterized by numerous major heat waves, with record‐breaking temperatures reported also during the summer of 2021. While most previous studies on heat waves were based on land‐only datasets (station or gridded)

Spatial and Temporal Characteristics of High-Temperature Heat Wave Disasters in Chongqing

open access: yesAtmosphere, 2022
In the background of global warming, heat wave disasters have become more frequent globally, and mountainous cities are more seriously affected by heat wave disasters due to the special features of topography and urban morphology. This paper analyzes the

Collapsing heat waves

open access: yesMathematical and Computer Modelling, 2007
In certain combustion models, an initial temperature profile will develop into a combustion wave that will travel at a specific wave speed. Other initial profiles do not develop into such waves, but die out to the ambient temperature. There exists a clear demarcation between those initial conditions that evolve into combustion waves and those that do ...

Wave heating of the solar atmosphere [PDF]

open access: yesPhilosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2015
Magnetic waves are a relevant component in the dynamics of the solar atmosphere. Their significance has increased because of their potential as a remote diagnostic tool and their presumed contribution to plasma heating processes. We discuss our current understanding of coronal heating by magnetic waves, based on recent observational evidence and ...
