Source apportionment and driving mechanisms of black carbon in a mountainous megacity: insights from urban–suburban observations in Chongqing, China [PDF]

Environmental Science: Atmospheres
Black carbon, a strongly light-absorbing aerosol from incomplete combustion, has raised global concern due to its substantial impacts on climate forcing, air quality degradation, and public health risks.

Stably stratified canopy flow in complex terrain [PDF]

Atmospheric Chemistry and Physics, 2015
Stably stratified canopy flow in complex terrain has been considered a difficult condition for measuring net ecosystem–atmosphere exchanges of carbon, water vapor, and energy.

Surface Wind Regionalization in Complex Terrain [PDF]

Journal of Applied Meteorology and Climatology, 2008
AbstractDaily wind variability in the Comunidad Foral de Navarra in northern Spain was studied using wind observations at 35 locations to derive subregions with homogeneous temporal variability. Two different methodologies based on principal component analysis were used to regionalize: 1) cluster analysis and 2) the rotation of the selected principal ...

A Dual-Branch Transformer with Adaptive Residual Correction for Improving High-Ozone Forecast Skill

Atmosphere
Near-surface ozone (O3) pollution is a growing environmental concern, particularly in the Beijing–Tianjin–Hebei (BTH) region, one of China’s most densely populated megacity clusters experiencing increasingly severe O3 episodes.

Comparative Analysis of Summer Deep Convection Systems over the Tibetan Plateau and Sichuan Basin

Atmosphere
Based on GPM satellite observations during June to September from 2014 to 2023, deep convective systems (DCSs) over the Tibetan Plateau and Sichuan Basin exhibited distinct spatiotemporal and structural characteristics.

Ensemble Kalman filter assimilation of near-surface observations over complex terrain: comparison with 3DVAR for short-range forecasts [PDF]

Tellus: Series A, Dynamic Meteorology and Oceanography, 2013
Surface observations are the main conventional observations for weather forecasts. However, in modern numerical weather prediction, the use of surface observations, especially those data over complex terrain, remains a unique challenge.

Remote influence of the Atlantic multidecadal oscillation on the autumn surface air temperature in Southwest China

Earth and Planetary Physics
Southwest China (SWC) is one of the major grain-producing areas in China, and the surface air temperature (SAT) during autumn has a substantial influence on grain production and planting.

Preliminary Assessment of Frozen Ground Thermal Degradation in the Yangtze–Yellow River Source Regions and Its Hydrological Associations with the Western Sichuan Basins

Atmosphere
The Tibetan Plateau sustains major Asian rivers through extensive cryospheric resources. However, hydrological associations of frozen ground degradation on downstream water availability remain insufficiently quantified.

Characterizing atmospheric stability in complex terrain [PDF]

Wind Energy Science
Characterizing atmospheric stability becomes challenging in heterogeneous, complex terrain. We use data from 47 meteorological towers associated with the Perdigão field campaign to recommend data-processing approaches and to assess the limitations of ...

Modelling surface climate over complex terrain for landscape ecology [PDF]

, 2000
Climate exerts a fundamental control on ecosystem function, species diversity and distribution. Topographic variability may influence surface climate, through processes operating at a landscape- scale.
