Surface winds in the Euro-Mediterranean area: the real resolution of numerical grids [PDF]

Annales Geophysicae, 2004
Surface wind is a variable of great importance in forcing marine waves and circulations, modulating surface fluxes, etc. Surface wind defined on numerical grids is currently used in forecast-analysis, as well as in climatology. Gridded fields, however,

Climatology and Trends of Sub‐Daily Precipitation Extremes in Croatia

International Journal of Climatology, EarlyView.
Sub‐daily extreme precipitation indices reveal pronounced spatial variability, with the highest intensities and frequencies across the Adriatic region and the highlands. Seasonal and diurnal patterns highlight distinct regional behaviour, including summer maxima over the continental interior and nocturnal or early‐morning peaks along the Adriatic coast.

Dampening of the Precipitation Response to Aerosol Pollution From Turbulence in Cumulus Clouds

Geophysical Research Letters
Using aircraft observations and a cloud model with particle‐based microphysics, it is shown that the enhancement of drop collision‐coalescence from turbulence in clouds not only leads to earlier onset of rain in warm cumulus clouds as past studies have ...

How Are Tornadic Supercell Soundings Significantly Different From Nearby Baseline Environments?

Geophysical Research Letters, 2023
This study explores how tornadic supercell soundings significantly differ from the same‐location and same‐hour baseline environment soundings, sampled from the days prior to or following the event. Permutation testing is used to identify whether sounding‐

Statistical Characteristics of Mesoscale Convective Systems Initiated over the Tibetan Plateau in Summer by Fengyun Satellite and Precipitation Estimates

Remote Sensing, 2021
In order to investigate the key characteristics of mesoscale convective systems (MCSs) initiated over the Tibetan Plateau (TP) in recent years and the main differences in circulation and environmental factors between different types of MCSs, an automatic

Surface and Tropospheric Climatic Trends in the Galápagos Archipelago Based on the Galápagos Archipelago Refined Analysis Dataset

International Journal of Climatology, EarlyView.
The Galápagos Archipelago's near‐surface climate is primarily influenced by interannual El Niño‐Southern Oscillation variability, with no statistical evidence for long‐term trends in air temperature, humidity, or precipitation. While tropospheric warming and increased atmospheric stability are observed, these trends are largely decoupled from near ...

Statistical Analysis of Mesovortices during the First Rainy Season in Guangdong, South China

Remote Sensing, 2023
Based on Doppler radar observation and reanalysis data, the statistical characteristics of mesovortices (MVs) during the first rainy season (April–June) in Guangdong, South China, from 2017 to 2019 are studied, including their spatiotemporal ...

Climatic Drivers of the Area Burned by Winter Wildfires in Northern Italy

International Journal of Climatology, EarlyView.
This study investigates winter wildfires occurring between November and April in northern Italy over the period 2008–2022. By integrating high‐resolution burned‐area data with gridded climatic indices derived from 150 weather stations, it identifies spatial and temporal wildfire patterns, highlights the most fire‐prone mountain areas through pixel ...
