Seasonal Modulation of ENSO Teleconnections to Horn of Africa Rainfall

open access: yesGeophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract Rainfall over the Horn of Africa (HoA) exhibits pronounced interannual variability linked to the El Niño‐Southern Oscillation (ENSO). However, the seasonal evolution of ENSO‐driven rainfall anomalies is not adequately explained by the ENSO, particularly the Niño3.4 index.

Drivers of 2024 Record Low Sea Ice in Eastern Hudson Bay: A Satellite Era Perspective

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 21, 16 November 2026.
Abstract By late May 2024, Hudson Bay (HB) reached record‐low sea ice extent (SIE) and sea ice concentration (SIC), which has been attributed to the persistent easterly winds in May 2024. This study further investigates the role of easterly winds as well as broader contributing factors.

Kernel detrended fluctuation analysis: A nonlinear, multivariate method for detecting long-range persistence

open access: yes
We introduce Kernel Detrended Fluctuation Analysis (kDFA), a multivariate, nonlinear generalization of detrended fluctuation analysis for quantifying long-range persistence in complex systems.

Evaluation of ERA5 Reanalysis Precipitation Over the Democratic People's Republic of Korea

open access: yesAtmospheric Science Letters, Volume 27, Issue 11, November 2026.
This study comprehensively validates ERA5 reanalysis precipitation against 39 ground‐based stations in the DPRK over 40 years (1981–2020). Key findings reveal: (1) ERA5 shows moderate annual skill (CC = 0.77) with systematic intensity‐dependent biases—overestimating light winter precipitation (false alarms) and smoothing extreme summer monsoon events; (

Minimizing the Effect of Sinusoidal Trends in Detrended Fluctuation Analysis

open access: yes, 2004
The detrended fluctuation analysis (DFA) [Peng et al., 1994] and its extensions (MF-DFA) [Kantelhardt et al., 2002] have been used extensively to determine possible long-range correlations in self-affine signals.

Ecosystem Health Assessment of Hulun Lake Using an eDNA Metabarcoding‐Based Phytoplankton Index of Biotic Integrity

open access: yesEcology and Evolution, Volume 16, Issue 11, November 2026.
Using environmental DNA metabarcoding data from 13 sampling sites, we assessed spatial variation in phytoplankton diversity, community composition, and biotic integrity across Hulun Lake. Phytoplankton diversity was higher in the northern and southern regions, whereas P‐IBI values indicated better ecological conditions in the central and northern ...

Correlation Properties of Heart Rate Variability for Exercise Intensity Monitoring and Prescription During Constant‐Load Cycling: A Comparison With Traditional Physiological Variables

open access: yesEuropean Journal of Sport Science, Volume 26, Issue 11, November 2026.
ABSTRACT This study investigated the applicability of the short‐term scaling exponent alpha 1 of detrended fluctuation analysis (DFA‐a1) as a marker of internal load during constant‐load cycling. The aim was to explore DFA‐a1 dynamics across the moderate, heavy, and severe intensity domains and assess its utility for both monitoring and prescribing ...
