Assessing Climate Change Impacts on the March 2024 Compound Floods and Saharan Dust Outbreak in Europe

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 12, 28 June 2025.
Abstract This study investigates whether and how climate change affected the compound extreme weather event that caused simultaneous floods in Portugal and an African dust outbreak across the Mediterranean region at the end of March 2024. The event was mainly driven by a large low pressure system located near Western Europe.

Global relevance of atmospheric and land surface drivers for hot temperature extremes [PDF]

Earth System Dynamics
Hot temperature extremes have severe impacts on society and ecosystems. These extremes are driven by both atmospheric and land surface processes, such as advection or reduced evaporative cooling.

Impact of Smoke Aerosol Loading on Lightning Characteristics of Pyrocumulonimbus Compared With Other High‐Based Thunderstorms

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 12, 28 June 2025.
Abstract Pyrocumulonimbus (pyroCb) is a form of deep convection that is generated by the heating from large wildfires and specific meteorology known for producing lightning. We study the lightning characteristics of five pyroCb events in British Columbia, Canada, from June 29 to July 1 of 2021, and compare them to other clean and smoke‐filled high ...

An Integrated Analysis of Ozone and Carbon Monoxide Over the Western Pacific Using Satellite and Aircraft Measurements During the ACCLIP Summer Campaign 2022

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 12, 28 June 2025.
Abstract The western Pacific exhibited a complex interplay of monsoonal dynamics and transport during the Asian Summer Monsoon Chemical & Climate Impact Project (ACCLIP) airborne field campaign in summer 2022. We analyze in situ observations of ozone (O3) and carbon monoxide (CO) from 29 research flights—profiling over South Korea and cruising over the

The Role of Tropical Cyclone Seeds on Modulating the Seasonal Cycle of Tropical Cyclone Frequency in the North Indian Ocean

Geophysical Research Letters, Volume 52, Issue 12, 28 June 2025.
Abstract This study investigates the seasonal cycle of tropical cyclones (TCs) in the North Indian Ocean (NIO) using a multi‐stage framework of tropical cyclogenesis that considers the TC seeds and TCs separately. We find that the May–June (MJ) pre‐monsoon season features fewer TC seeds (∼23) with high survival rates (SR, ∼2.8%), while the post‐monsoon

The applicability of the T/S method to geopotential anomaly computations in the Northeast Atlantic [PDF]

, 1983
Methods are tested for computing geopotential anomalies from temperature data in the subtropical Northeast Atlantic. Mean temperature-salinity, salinity-depth and density-depth relationships are determined for 3 x 3° squares, using hydrographie data ...
