Vegetation Carries the Signature of Recent Precipitation

by Valeriy Ivanov 3 October 202228 September 2022

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

by Valeriy Ivanov 21 July 202221 July 2022

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.

Lightning in Alaskan Tundra Ignites Most Fires

by Valeriy Ivanov 19 July 202211 August 2022

Cloud-to-ground lightning is found to be the most important controller of wildfire occurrence in the Artic tundra of Alaska from 2001 to 2019.

Not All Clays are Made Equal – and it Matters for Hydrology

by Valeriy Ivanov 10 February 20228 August 2022

Soil clay content is an important characteristic that affects many hydraulic and mechanical properties of soil; clay mineral type is important for their prediction.

Evolution is More Important than Environment for Water Uptake

by Valeriy Ivanov 8 February 20223 May 2022

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.

Stream Hydraulic Geometry 1.01

by Valeriy Ivanov 7 December 20201 December 2020

New research provides a theoretical explanation of channel cross section geometry dependence on flow rate that is commonly observed and described with power-laws.

Atmospheric Rivers Trigger Heavy Snowmelt in Western USA

by Valeriy Ivanov 13 December 20195 December 2019

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.

A Closure on Sea Level Rise Budget

by Valeriy Ivanov 27 November 201928 October 2021

Terrestrial water loss may explain the lack of previous budget closure in global mean sea level rise.

Machine Learning Improves Satellite Rainfall Estimates

by Valeriy Ivanov 31 October 201925 July 2022

A new deep learning approach bridges ground rain gauge and radar data with spaceborne radar observations of Tropical Rainfall Measuring Mission to improve precipitation estimation.
