EFFECTS OF LAND COVER, WATER REDISTRIBUTION, AND TEMPERATURE ON ECOSYSTEM PROCESSES IN THE SOUTH PLATTE BASIN [PDF]

, 1998
Over one‐third of the land area in the South Platte Basin of Colorado, Nebraska, and Wyoming, has been converted to croplands. Irrigated cropland now comprises 8% of the basin, while dry croplands make up 31%.

Internal Lee Waves Control Deep Ocean Turbulent Mixing in the Antarctic Circumpolar Current at 50°E

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Full‐depth (Surface‐to‐bottom) turbulent kinetic energy dissipation (TKED) observed with fast‐response thermistors across the Antarctic Circumpolar Current (ACC) at 50° $\mathit{{}^{\circ}}$E is compared with the energy flux of bottom‐generated internal waves estimated with high‐resolution multibeam bathymetry.

Recent progress in atmospheric modeling over the Andes – part I: review of atmospheric processes

Frontiers in Earth Science
The Andes is the longest mountain range in the world, stretching from tropical South America to austral Patagonia (12°N-55°S). Along with the climate differences associated with latitude, the Andean region also features contrasting slopes and elevations,

Orography-Induced Gravity Wave Drag Parameterization in the Global WRF: Implementation and Sensitivity to Shortwave Radiation Schemes

Advances in Meteorology, 2010
This paper describes the implementation of the orographic gravity wave drag (GWDO) processes induced by subgrid-scale orography in the global version of the Weather Research and Forecasting (WRF) model. The sensitivity of the model simulated climatology

Investigations of severe/tornadic thunderstorm development and evolution based on satellite and AVE/SESAME/VAS data [PDF]

The use of rapid scan satellite imagery to investigate the local environment of severe thunderstorms is discussed. Mesoscale cloud tracking and vertical wind shear as it affects thunderstorm relative flow are mentioned. The role of pre-existing low level

Contribution of Unconventional Mesoscale Eddies to Surface Poleward Heat Flux in the Southern Ocean Over the Past Three Decades

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Mesoscale eddies play a key role in transporting heat poleward across the Antarctic Circumpolar Current (ACC). In addition to conventional eddies (warm‐core anticyclones and cold‐core cyclones), recent studies have detected a significant number of unconventional eddies at the surface (cold‐core anticyclones and warm‐core cyclones).

Upper‐Level Turbulence in the North American and Asian Summer Monsoon Regions Sampled in Recent Aircraft Campaigns

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Small‐scale turbulence above 10 km is investigated using observations from two recent airborne field campaigns: the Asian Summer Monsoon Chemical & Climate Impact Project (ACCLIP) and the Dynamics and Chemistry of the Summer Stratosphere (DCOTSS). Turbulence is enhanced by factors of 2–24 inside clouds, within 100 km of active deep convection,

Measuring Clear‐Air Vertical Motions From Space

AGU Advances
Measuring vertical velocity in the atmosphere has long been a challenge due to its small magnitude. Taking advantage of the modulation of free tropospheric relative humidity by vertical motions, we derive analytical relationships that allow us to ...

Modelling representation errors of atmospheric CO₂ mixing ratios at a regional scale [PDF]

Atmospheric Chemistry and Physics, 2008
Inverse modelling of carbon sources and sinks requires an accurate quality estimate of the modelling framework to obtain a realistic estimate of the inferred fluxes and their uncertainties.

The application of satellite data to study the effects of latent heat release on cyclones [PDF]

, 1984
Generalized energetics were studied for nonlinear inviscid symmetric instability (SI). It was found that the linear theory fails to predict the stability in certain cases where the basic state is transitional between stability and instability.
