Linking weather variability and climatic pressure dipole in the Antarctic region of Amundsen – Bellingshausen – Weddell Seas

Український антарктичний журнал
The climatic pressure dipole, formed by the Amundsen Sea Low (ASL) and the high-pressure area east of the Antarctic Peninsula (AP), is a major contributor to weather variability in West Antarctica and the peninsula region.

Dry–Hot Compound Events Driving the 2024 Pantanal Wildfires

International Journal of Climatology, EarlyView.
Extreme wildfires in the Pantanal in 2024 were driven by a cascade of heatwaves, rainfall deficits and the absence of the annual flood pulse. These conditions dried soils and rivers, enhanced fuel accumulation and enabled early and intense fire outbreaks.

Spatiotemporal Changes in Precipitation Concentration in the Atlantic‐European Region

International Journal of Climatology, EarlyView.
This study analyses changes in precipitation concentration using ERA5 and E‐OBS datasets. Gini index as a measure of precipitation concentration revealed a gradual expansion of areas with increasing unevenness in precipitation distribution across the Atlantic‐European region since 1961.

Sampling Biases in Daily Average Temperatures From Greenland Climate Records

International Journal of Climatology, EarlyView.
Biases are introduced in the calculation of daily average temperatures due to uneven sampling times for the investigated weather station network in Greenland. The figure shows the network, an example of a daily temperature cycle with daily averages based on all or only two observations and an overview of how the number of observations per day changes ...

Large Proportions of Surface Ozone and Premature Mortality Due to a Stratospheric Intrusion Event in North China

International Journal of Climatology, EarlyView.
This study, by examining a typical stratospheric intrusion event that occurred in North China from 30 to 31 July 2021, found that the event led to a sharp increase in near‐surface ozone concentrations by 23 ppbv within 36 h, accounting for 40% of the total observed ozone levels, with localised peaks exceeding 30 ppbv.

Spatiotemporal Droughts Propagation and Direct Driving Variables Under Climate Change Projections: A Case Study of Tunisia

International Journal of Climatology, EarlyView.
Drought spatiotemporal propagation and direct driving variables are assessed at multiple time steps with high spatial resolution using various drought indices (SPI, SPEI and SPDI) and entropy based mutual information under an ensemble of climate change projections over Tunisia. ABSTRACT Projecting drought occurrence and spatiotemporal propagation under

Sunshine Duration in Brazil From Meteosat (1983–2020): Climatology, Variability and Long‐Term Trends

International Journal of Climatology, EarlyView.
Using nearly four decades of Meteosat satellite data (1983–2020), this study presents a country‐wide climatology of sunshine duration (SDU) in Brazil. The results reveal marked regional contrasts, dominant modes of variability, and significant long‐term trends, providing new information on the most relevant meteorological systems that influence SDU and

Connecting Large‐Scale Atmospheric and Land Surface Patterns to New England Riverine Peak Flow Events

Geophysical Research Letters
Riverine flooding in the New England region of the United States of America is devastating, arises from multiple processes during any season, and lacks ties to common climate indices.
