Summer Fire Means Winter Melt
Changing wildfire activity in California may impact seasonal hydrology by causing intense snowmelt during winter in areas where fires extend into higher elevation zones.

Streamflow Drought Intensification in the European Alps
A five-decade analysis of drought generation processes in the Alps shows their changing seasonality in high-elevation basins with increasingly frequent droughts caused by a lack of snowmelt water.

Vegetation Carries the Signature of Recent Precipitation
Vegetation response to precipitation is important for near-term weather predictability, and researchers show that such a response can occur within a few days and last up to two months.

A Unique Glimpse at Sediment Erosion and Deposition by Wind
The Lut Desert in Iran is an exceptional natural laboratory to study how wind moves sediment across the landscape. A new study quantifies erosional and depositional sediment fluxes of the desert.

Evolution is More Important than Environment for Water Uptake
Despite conventional assumptions, a new study shows that evolutionary proximity of species defines root water uptake strategies, not their position in landscape or ambient environment.

Atmospheric Rivers Trigger Heavy Snowmelt in Western USA
A rare atmospheric phenomenon that transports large quantities of water vapor into the coastal watersheds of the western USA is responsible for up to 10–20% of intense snowmelt events in the region.
