CaMa‐PyTorch (v1.0): A New Catchment‐Based Macro‐Scale Floodplain Model Written in PyTorch
Earth and Space Science, Volume 13, Issue 11, November 2026.Abstract Accurate simulation of river discharge underpins hydrological research, climate‐impact assessment, and flood forecasting. CaMa‐Flood, a widely used global river‐routing model, applies physically based principles to represent water transport through river networks.

More Frequent, Faster, and Seasonally Reorganized Drought‐to‐Pluvial Transitions in U.S. Cities
Earth's Future, Volume 14, Issue 11, November 2026.Abstract Hydroclimatic variability is projected to intensify under continued warming, yet the evolving likelihood, rapidness, and seasonal timing of drought‐to‐pluvial transitions remain poorly quantified. Here, we develop a probabilistic framework that integrates a severity‐resolved Markov formulation to estimate conditional drought‐to‐pluvial ...

Dynamic Hydroclimate Fuels Cryptic Sulfur Cycling and Iron and Carbon Impacts in Wetlands
Water Resources Research, Volume 62, Issue 11, November 2026.Abstract Wetland water quality plays a vital role in controlling emissions of methane, a strong greenhouse gas, and it is regulated by the sequestration of nutrients and toxic metals on iron‐rich soils. However, the stability of these functions under shifting precipitation and temperature regimes remains unknown, because of complex and unconstrained ...

An Empirical Simplification of the Temperature Penman-Monteith Model for the Tropics
Journal of Agricultural Science, 2010 Une équation empirique simple (EPM) est présentée pour raccourcir considérablement les étapes de calcul nécessaires pour estimer l'évapotranspiration de l'herbe de référence (ETo) sous les tropiques à l'aide de l'équation de Penman-Monteith (TPM) de la FAO-56 lorsque les seules données météorologiques disponibles sont celles de la température ...

A Demonstrated Workflow to Efficiently Identify Better Performing Process‐Based Model Configurations
Water Resources Research, Volume 62, Issue 11, November 2026.Abstract There are often competing options for process representation when designing process‐based hydrologic models. Comparing candidate model configurations during model development can be computationally expensive and existing methods for evaluating prior‐data conflict often cannot distinguish between multiple models with low prior‐data conflict ...

Penman-Monteith与Penman修正式计算塔里木盆地参考作物潜在腾发量比较
, 2005 利用1989～1996年阿克苏水平衡试验站的气象资料,对Penman-Monteith公式和Penman修正式计算的参考作物潜在腾发量进行了比较。Penman修正式计算的参考作物潜在腾发量年值略大于Penman-Monteith公式计算的年值,绝对偏差为42～128mm,相对偏差为3.3～9.8%,且年际间变化不大。各月的参考作物潜在腾发量变化较大,绝对偏差可正可负,1、2、12月小于0,3～10月大于0,相对误差1、12月较大,2、11月较小,其它月份变化不大 ...
