Preferred pathways of traveling extreme events in land precipitation and temperature

Extreme precipitation events and hot-weather events are usually examined at separate grids of a longitude-latitude map. A spatiotemporal perspective can provide additional insights, such as the spatial extent of extreme events and their potential traveling across the spatial domain over time. Here, we present the regular long-distance traveling patterns of these extreme events, highlighting the preferred spatial pathways through which the extreme precipitation events and hot-weather events tend to travel. Our in-depth analysis reveals that such long-distance traveling behaviors are influenced by midlatitude Rossby waves, and these preferred pathways can offer valuable information for early warning of downstream extreme events, potentially enhancing preparedness and response strategies.
