Formulation and Implementation of a Dynamic Roughness Length for Improved Surface Wind Speeds in WRF

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract Accurate near‐surface winds from the Weather Research and Forecasting (WRF) model are essential for wind‐energy applications, yet persistent biases remain that depend on terrain, season, and land cover. This study develops and evaluates an observation‐informed, time‐varying aerodynamic roughness length for WRF. The roughness length is inferred

Evaluating Fire Indices for Fire Ignition and Spread Rate in the Western United States

Earth's Future, Volume 14, Issue 8, August 2026.
Abstract Wildfires are complex events that are challenging to model. Researchers and land managers often rely on fire indices as a proxy of fire risk in operational forecasts and future projections. However, in the scientific literature, the choice of which fire index to use is often arbitrary and not tied to specific fire behaviors. Here, we provide a

Cascading River‐Lake Hydrological Regulation Reshapes Carbon Budgets of Floodplain Lakes in the Yangtze River Basin

Earth's Future, Volume 14, Issue 8, August 2026.
Abstract The carbon budget of floodplain lakes is regulated by natural hydrological processes, yet the role of human interventions, including cascade river‐lake hydraulic projects, remains unclear. We evaluated the combined effects of the Three Gorges Dam (TGD) located on the Yangtze River and the proposed lake‐specific hydraulic projects (LHPs) on the

Reassessing Alpine Permafrost Thermal State by Accounting for Ground Ice

Earth's Future, Volume 14, Issue 8, August 2026.
Abstract Permafrost thermal state, representing the stored “cold energy” in the ground, is crucial for assessing permafrost changes. However, the conventional metric, mean annual ground temperature (MAGT), has inherent limitations because it overlooks the thermodynamic contribution of ground ice.

Agricultural Emissions of Reactive Nitrogen Gases From Constrained Simulations Using the Community Land Model

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 8, August 2026.
Abstract Reactive nitrogen (Nr) gases (NH3, N2O, and NO) emitted from agricultural fields constitute a substantial portion of the Nr flux from land to the atmosphere. Here, we coupled the Flows of Agricultural Nitrogen (FANv3) with a modified version of the Community Land Model (CLM5.1) to produce a model (CLM‐FANv3) that simulates the emissions of NH3,
