Evaluating the Performance of Uni‐ and Multivariate Bias Correction Techniques: Challenges in Preserving Temporal and Dependence Structures

Water Resources Research, Volume 62, Issue 2, February 2026.
Abstract Global Climate Models (GCMs) are essential for simulating past and future climates but suffer from systematic biases and coarse resolution, limiting direct applications. Bias correction (BC) and downscaling, using dynamical or statistical methods, address these issues. Quantile mapping (QM)‐based BC is widely used, yet it distorts dependencies,

Changes in Atmospheric Convection Over the Indo‐Pacific Warm Pool and Coupled IOD and ENSO Patterns During the Last Glacial Maximum

Geophysical Research Letters
This study investigates how the convection over the Indo‐Pacific Warm Pool responds to the Last Glacial Maximum conditions. Paleoproductivity records that can indicate seasonal wind dynamics are combined with modeling data.

Normalizing the causality between time series

, 2015
Recently, a rigorous yet concise formula has been derived to evaluate the information flow, and hence the causality in a quantitative sense, between time series. To assess the importance of a resulting causality, it needs to be normalized.

The effect of doubled CO2 and model basic state biases on the monsoon-ENSO system. II: Changing ENSO regimes [PDF]

, 2007
Integrations of a fully-coupled climate model with and without flux adjustments in the equatorial oceans are performed under 2×CO2 conditions to explore in more detail the impact of increased greenhouse gas forcing on the monsoon-ENSO system.

Decadal‐Scale In Situ Scanning of a Stalagmite From Southwest China Reveals Blake Geomagnetic Excursion Structure

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract We present a decadal‐scale paleomagnetic analysis of a stalagmite collected from Shuixi Cave, southwest China, spanning 89−123 ka. Our findings include: (a) Magnetite is the dominant magnetic mineral, and paleomagnetic directions can be obtained via demagnetization; (b) Magnetic scanning at 0.1‐mm resolution captures key magnetic features ...

Variation of Wyrtki Jets Influenced by Indo-Pacific Ocean–Atmosphere Interactions

Journal of Marine Science and Engineering
As important components of the equatorial current system in the Indian Ocean, Wyrtki jets (WJs) play a significant role in distributing heat and matter in the East and West Indian Oceans.

Indian Ocean Dipole and El Niño/Southern Oscillation impacts on regional chlorophyll anomalies in the Indian Ocean [PDF]

Biogeosciences, 2013
Abstract. The Indian Ocean Dipole (IOD) and the El Niño/Southern Oscillation (ENSO) are independent climate modes, which frequently co-occur, driving significant interannual changes within the Indian Ocean. We use a four-decade hindcast from a coupled biophysical ocean general circulation model, to disentangle patterns of chlorophyll anomalies driven ...

Influences of Meridional SST Gradient Biases on Subsurface Temperature in the Tropical Indian Ocean: Roles of SMOC and ITF

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract The tropical Indian Ocean (IO) exhibits persistent biases in sea surface temperature (SST) climatology across Coupled Model Intercomparison Project Phase 6 (CMIP6) models, particularly during boreal winter. These biases manifest as a meridional dipole with warm SSTs in northern tropics and cool SSTs in south.

Climate Change Alters Teleconnections

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Internal modes of climate variability, such as El Niño and the North Atlantic Oscillation (NAO), can have strong influences upon distant weather patterns, effects that are referred to as “teleconnections.” The extent to which anthropogenic climate change has and will continue to affect these teleconnections, however, remains uncertain.

Contributions of Indonesian Throughflow to eastern Indian Ocean surface variability during ENSO events

Atmospheric Science Letters, 2020
The contribution of ocean transport to the transition between the Indian Ocean Dipole mode (IOD) and the Indian Ocean Basin mode (IOB) during El Niño–Southern Oscillation (ENSO) years is investigated using reanalysis products. Composite analysis suggests
