Influence of biomass burning and anthropogenic emissions on ozone, carbon monoxide and black carbon at the Mt. Cimone GAW-WMO global station (Italy, 2165 m a.s.l.) [PDF]

Atmospheric Chemistry and Physics, 2013
This work investigates the variability of ozone (O₃), carbon monoxide (CO) and equivalent black carbon (BC) at the Italian Climate Observatory "O. Vittori" (ICO-OV), part of the Mt. Cimone global GAW-WMO station (Italy).

Moisture Sources and Synoptic‐Scale Controls on Wet Season Event Rainfall in Mexico City: Evidence From Stable Isotopes

Hydrological Processes, Volume 40, Issue 3, March 2026.
Precipitation stable isotopes, combined with backward air mass trajectories and synoptic meteorology analyses, revealed that rainfall in Mexico City is primarily originated from the Caribbean Sea, Gulf of Mexico and continental regions, modulated by troughs and tropical waves. Event‐scale rainfall showed strong variability in isotope compositions, with

A New Climatology of Continentality Based on Lagrangian Air Mass Travel Times From the Ocean

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Climate classifications such as the Köppen classification have a long tradition and wide fields of application. An important classification aspect is continentality, for which we present a new metric based on Lagrangian dispersion model calculations.

Investigating the Large-Scale Transport of a Volcanic Plume and the Impact on a Secondary Site

Atmosphere, 2020
Volcanic plumes can be transported across vast distances and can have an impact on solar ultraviolet radiation (UVR) reaching the surface due to the scattering and absorption caused by aerosols.

Optical, microphysical, mass and geometrical properties of aged volcanic particles observed over Athens, Greece, during the Eyjafjallajökull eruption in April 2010 through synergy of Raman lidar and sunphotometer measurements [PDF]

Atmospheric Chemistry and Physics, 2013
Vertical profiles of the optical (extinction and backscatter coefficients, lidar ratio and Ångström exponent), microphysical (mean effective radius, mean refractive index, mean number concentration) and geometrical properties as well as the mass ...

Mesoscale dynamics of cyclone Leslie (2018): A diagnostic analysis of a rare Iberian landfall

Quarterly Journal of the Royal Meteorological Society, Volume 152, Issue 775, January 2026 Part B.
This study presents a successful numerical simulation of cyclone Leslie (2018), using WRF‐ARW v4.5.1. Several mesoscale dynamics were identified indicative of the occurrence of sting jet and cold conveyor belt, which potentiated the record‐breaking winds in central Portugal.

Reduction of Residence Time of Air in the Arctic Since the 1980s

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract The Arctic has seen dramatic changes in recent decades. Here we use a simple metric, the Arctic residence time of air, that is, the time air spends uninterruptedly north of 70° ${}^{\circ}$N, to evaluate how these changes have affected the high‐latitude atmospheric circulation in the last 40 years.

Heavy Rainfalls Over the Western Java Region During the Cross‐Equatorial Northerly Surges in Mid‐February 2021

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 24, 28 December 2025.
Abstract The cross‐equatorial northerly surges (CENSs) often induce severe rainfalls in the Java region; however, the role of CENSs in the formation and moisture supply of these rainfalls remains unclear. To evaluate this, we analyzed the CENS‐related heavy rainfalls over the western Java region in mid‐February 2021 based on observations, ERA5 ...

Atmospheric Rivers Sustain and Reshape Hydrological Responses Across Chinese River Basins

Earth's Future, Volume 13, Issue 12, December 2025.
Abstract Atmospheric rivers (ARs) are key drivers of hydrological change, but their role in sustaining and reshaping hydrological responses in Chinese river basins remains insufficiently quantified. We detect ARs for 1950–2023 using integrated water vapor transport (IVT) dual percentile thresholds with morphological filtering for elongated, persistent ...
