Anthropogenic forcing has increased the risk of longer-traveling and slower-moving large contiguous heatwaves

Heatwaves are consecutive hot days with devastating impacts on human health and environment. These events may evolve across both space and time, characterizing a spatio-temporal contiguous propagation pattern that has not been fully understood. Here we track the spatiotemporally contiguous heatwaves in both reanalysis datasets and model simulations, and examine their moving patterns (i.e., moving distance, speed, and direction) in different continents and periods. Our findings provide important implications for the adaptation and mitigation of globally connected extreme heatwaves. The tracked contiguous heatwave events are saved as the PICKLE format. More detailed information related to the uploaded data and code can be found in “README.pdf”. If you have any questions when using the dataset and code of contiguous heatwaves, please feel free to contact Miss Sijia Wu via [e-mail], Dr. Ming Luo via [e-mail].
