Long-term climatology of air mass transport through the Tropical Tropopause Layer (TTL) during NH winter [PDF]

, 2007
A long-term climatology of air mass transport through the tropical tropopause layer (TTL) is presented, covering the period from 1962–2005. The transport through the TTL is calculated with a Lagrangian approach using radiative heating rates as vertical ...

El Niño Events Enhance Melting of Sea Ice in the West of Greenland

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Using reanalysis data sets and numerical simulations, this study investigates the linkage between El Niño events and spring Arctic sea ice melt rate (AMR) in the west of Greenland. The results indicate that the accelerated spring AMR often corresponds to the previous winter's El Niño–like sea surface temperature anomalies.

On CMIP6 Model Consensus for the Climate Response in Eurasian Winter to Historical Volcanic Eruptions

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract This study provides a comprehensive analysis of the climate response in Northern Hemisphere (NH) winter to major volcanic eruptions of the past, using multi‐member ensembles of historical experiments of 15 models from the Coupled Model Intercomparison Project Phase 6 (CMIP6) and three reanalysis data sets.

Modulation of winter precipitation associated with tropical cyclone of the western North Pacific by the stratospheric Quasi-Biennial oscillation

Environmental Research Letters, 2021
Tropical cyclone precipitation (TCP) has increasing impacts on many coastal regions under global warming. Causes of TCP variation have been principally explored in the troposphere.

Statistical evidence links exceptional 1995 Atlantic hurricane season to record sea warming [PDF]

, 2004
Tropical cyclones rank above earthquakes as the major geophysical cause of loss of life and property (Bryant, 1991; Houghton, 1994). In the United States alone, the damage bill from mainland landfalling hurricanes over the last 50 years averages $2.0 ...

A Novel Methodology for Probing the Observed Influence of the QBO on Tropical Tropospheric Climate

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.
Abstract The stratospheric Quasi‐Biennial Oscillation (QBO) is characterized by descending bands of wind and temperature anomalies in the tropical stratosphere with a mean period of ∼28 months. Numerous studies have argued that the QBO has a significant impact on tropical tropospheric climate.

Seasonal Predictions and Their Applications in the Mediterranean Region: Part I—Sources of Predictability and Prediction Skill

International Journal of Climatology, Volume 46, Issue 5, April 2026.
The ability to predict climate fluctuations at seasonal timescales offers significant socio‐economic benefits. However, limited understanding of predictability mechanisms and model errors hinders forecast quality. Recent research has improved forecasting systems and data quality.

Windows of opportunity in subseasonal weather regime forecasting: A statistical–dynamical approach

Quarterly Journal of the Royal Meteorological Society, Volume 152, Issue 776, April 2026 Part A.
This study explores how the atmospheric state at initialisation creates windows of opportunity for improving week 3 forecasts of weather regime activity. Greenland blocking activity increases following Madden–Julian Oscillation phases 7, 8, and 1 and weak stratospheric polar vortex states, revealing patterns exploitable by statistical models.

Forecast verification using information and noise

Quarterly Journal of the Royal Meteorological Society, Volume 152, Issue 776, April 2026 Part A.
Verification of weather forecasts is usually expressed in terms of total error metrics. This is useful for end users of the forecasts but does not allow evaluation of the intrinsic information content of the forecasts. To overcome this limitation, we propose a new total error decomposition into information and noise error measures, connect it to ...
