Potential for seasonal flood forecasting in West Africa using climate indexes

Journal of Flood Risk Management
Floods are among the most devastating natural disasters and are expected to become more severe with changing climate and population growth. Flood forecasting is one of the key components of flood risk reduction.

Upper Tropospheric Water Vapor Transport from Indian to Sahelian Regions

Atmosphere, 2018
We present a study of upper tropospheric westward transport of air masses coming from the Indian monsoon zone over the period 1998–2008. The objective is to characterize upper tropospheric transport of water vapor from the Indian to Sahelian ...

Influence of Teleconnections on the Precipitation

, 2021
Precipitation plays vital role in the economy of agricultural country like Pakistan. Baluchistan being the largest province of Pakistan in term of land is facing reoccurring droughts as well as flashflood due unprecedent torrential precipitation pattern.

Alaskan Ridge Blocking and Associated Winter Cold Conditions Over North America

International Journal of Climatology, Volume 46, Issue 8, 30 June 2026.
Multi‐decadal (1979–2023) analysis reveals that wintertime reductions in the meridional gradient of potential vorticity (PVy) over the Bering Sea are recurrent but episodic features of North Pacific circulation. These suppressed PVy states consistently co‐occur with amplified Alaskan ridging, weakened mid‐tropospheric westerlies and a downstream warm ...

Non‐Stationary Dry‐Spell Hazard Probabilities for Spain

International Journal of Climatology, Volume 46, Issue 8, 30 June 2026.
This study assesses long‐term changes in dry‐spell hazard probabilities across Spain (1961–2024) using a novel non‐stationary extreme value framework applied to daily precipitation records from a dense observational network. Results show that dry‐spell duration and associated return levels are dominantly stationary, with non‐stationary models providing

Eastern Pacific Corals Track Robust ENSO Variability and Stronger La Niña Events 4,000 Years Before Present

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The interannual El Niño‐Southern Oscillation (ENSO) triggers extreme climate events worldwide. Geochemical proxies in coral skeletons from the eastern equatorial Pacific (EP) track ENSO conditions, constraining its long‐term variance and response to forcing.

Correcting Underestimated Internal Variability Fails to Reconcile Models With Observed Pacific SST Gradient Strengthening

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The equatorial Pacific zonal sea surface temperature (SST) gradient has strengthened since 1980, yet fewer than 1% of CMIP6 simulations reproduce this trend. We test whether underestimated internal variability explains this mismatch. Extreme El Niño events enhance interdecadal variability of the gradient, but CMIP6 models simulate them too ...

Effect of teleconnection patterns on cloudiness in winter in Poland

The subject of the study was the effect of teleconnection patterns on cloudiness in Poland in the period 1990–2020. The analysis was conducted based on daily cloudiness values from 34 measurement stations of Institute of Meteorology and Water Management -

Reduced Distinctiveness of Extreme El Niño Teleconnections in Warmer Climates

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract In today's climate, extreme El Niño events (e.g., 1982–1983, 1997–1998) generate stronger and eastward‐shifted teleconnections relative to moderate El Niño and La Niña events, leading to distinct North American impacts such as enhanced rainfall over California and warming over northeastern North America.
