Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.Abstract Dry‐wet whiplash events profoundly impact society and the environment, yet their attribution remain poorly understood. This study reveals that the unprecedented interannual wet‐to‐dry transition (return period: 979.2 years) in South China's 1962–1963 pre‐flood season is co‐driven by internal variability and volcanic forcing.

A Method of Moments Estimator of Tail Dependence in Elliptical Copula Models
An elliptical copula model is a distribution function whose copula is that of an elliptical distri- bution. The tail dependence function in such a bivariate model has a parametric representation with two parameters: a tail parameter and a correlation ...

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 11, 16 June 2026.Abstract Socioeconomic drought, which occurs when water demand exceeds available supply and often leads to water withdrawal restrictions, affects water resource management. However, the relationship between large‐scale moisture circulation and the occurrence of socioeconomic drought has not been well understood. In this study, we focused on the Yoshino

Atmospheric Science Letters, Volume 27, Issue 6, June 2026.This study investigates the multiscale evolution of forecast distributions using 1000‐member global circulation model ensembles. Initially different distributions converge to the same time‐varying equilibrium distribution, and the equilibration time scale noticeably exceeds the variance saturation time. Prior to equilibration, the forecast distribution

Causal Effect Estimation With TMLE: Handling Missing Data and Near Violations of Positivity
Biometrical Journal, Volume 68, Issue 3, June 2026.ABSTRACT We evaluate the performance of targeted maximum likelihood estimation (TMLE) for estimating the average treatment effect in missing data scenarios under varying levels of positivity violations. We employ model‐ and design‐based simulations, with the latter using undersmoothed highly adaptive lasso on the “WASH Benefits Bangladesh” data set to ...

Biometrical Journal, Volume 68, Issue 3, June 2026.ABSTRACT In this paper, we present novel methodologies that incorporate auxiliary variables for multiple hypotheses testing related to the main point of interest while effectively controlling the false discovery rate. When dealing with multiple tests concerning the primary variable of interest, researchers can use auxiliary variables to set ...

Copula Estimation for GARCH(1, 1) Processes
The possibility of identifying nonlinear time series using nonparametric estimates of the conditional mean and conditional variance were studied in many papers.
