Impacts of bias nonstationarity of climate model outputs on hydrological simulations
Hydrology Research, 2020 Bias correction methods are based on the assumption of bias stationarity of climate model outputs. However, this assumption may not be valid, because of the natural climate variability.

Flood Hazard Estimation under Nonstationarity Using the Particle Filter
Geosciences, 2020 The presence of the nonstationarity in flow datasets has challenged the flood hazard assessment. Nonstationary tools and evaluation metrics have been proposed to deal with the nonstationarity and guide the infrastructure design and mitigation measures ...

Global Changes in 20‐Year, 50‐Year, and 100‐Year River Floods
Geophysical Research Letters, 2021 Concepts like the 100‐year flood event can be misleading if they are not updated to reflect significant changes over time. Here, we model observed annual maximum daily streamflow using a nonstationary approach to provide the first global picture of ...

Integrating multi‐method surveys and recovery trajectories into occupancy models
Ecosphere, 2021 Conservation and management of animal populations requires knowledge of their occurrence and drivers that influence their distribution. Noninvasive survey methods and occupancy models to account for imperfect detection have become the standard tools for ...

Modeling Nonstationarity in Space and Time [PDF]
Biometrics, 2017 SummaryWe propose to model a spatio-temporal random field that has nonstationary covariance structure in both space and time domains by applying the concept of the dimension expansion method in Bornn et al. (2012). Simulations are conducted for both separable and nonseparable space-time covariance models, and the model is also illustrated with a ...

Nonstationarity of the link between the Tropics and the summer East Atlantic pattern
Atmospheric Science Letters, 2021 A 700‐year pre‐industrial control run with the MPI‐ESM‐LR model is used to investigate the link between the summer East Atlantic (SEA) pattern and the Pacific‐Caribbean rainfall dipole (PCD), a link that has previously been shown using ERA‐Interim ...
