Exploring the Influence of Equatorial Waves on a Record‐Breaking Extreme Precipitation Event in Central Sahel: Insights From Convection Permitting Simulations

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The floods of 01 September 2009 in Ouagadougou, Burkina Faso, were among the most severe in the Central Sahel's history, highlighting the region's persistent flood risk. This extreme precipitation event (EPE) was influenced by various atmospheric drivers, including Convectively Coupled Equatorial Waves (CCEWs).

Pan‐Regional Prolonged Droughts Linked to Consecutive La Niña Events

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract From 2020 to 2023, prolonged droughts affected Central‐West Asia, East Africa, and North America, causing widespread disruptions to regional hydroclimate and ecosystems. These droughts coincided with an unusually persistent cold state of the tropical Pacific associated with consecutive La Niña events.

Earth’s Outgoing Longwave Radiation Variability Prior to M ≥6.0 Earthquakes in the Taiwan Area During 2009–2019

Frontiers in Earth Science, 2020
This paper proposes an analysis method, using the National Oceanic and Atmospheric Administration satellite data, to trace variations in outgoing longwave radiation (OLR) for finding the precursors of earthquakes.

Anomalous Energy Fluxes and Feedback Parameter Over the Course of ENSO Events

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Internal variability may provide constraints on the global temperature response to forcing. Previous work showed that ENSO induces atmospheric stratification anomalies that lead to tropical low cloud anomalies not correlated with mean temperature. Here, we expand this argument. We discuss the physical processes leading to a canonical evolution

Tropical Controls on West Antarctic Ice Sheet Surface Mass Balance Interannual Variability in the Twentieth Century

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 11, 16 June 2026.
Abstract The West Antarctic Ice Sheet (WAIS) contains an ice volumetric equivalent of 5.3 m of global mean sea‐level rise. Understanding the climate mechanisms that influence WAIS surface mass balance (SMB) can help reduce uncertainties in sea‐level rise projections. Previous work has focused on trends related to temperature and the roles of well‐known

A Study of Diurnal Variation of OLR from the GOES Sounder

Journal of Atmospheric and Oceanic Technology, 2003
Abstract A multispectral outgoing longwave radiation (OLR) estimation technique is applied to GOES Sounder data to study the diurnal cycle of OLR. OLR data collected from several regional areas over the continental United States and adjacent oceans during July 1998 are analyzed to determine diurnal variations for clear-sky and all-sky conditions. It is

Current and Future Changes in Earth's Outgoing Infrared Spectrum

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Hyperspectral infrared satellite observations provide an information‐rich, global record of climate mean state and change without the structural uncertainties often present satellite retrievals and reanalyses. Current and planned hyperspectral satellite missions will continuously observe changes in Earth's outgoing infrared spectrum into the ...

Seasonal Characteristics of Mesoscale Convective Systems Over the Philippines

International Journal of Climatology, Volume 46, Issue 7, 15 June 2026.
This study examines how mesoscale convective systems (MCSs) over the Philippines are most frequent during boreal summer, while those in winter are longer‐lived and more intense due to cold surges and enhanced easterly moisture transport. Intraseasonal oscillations, such as the Madden‐Julian Oscillation (MJO) and the Boreal Summer Intraseasonal ...
