Estimating Wind‐Power Capacity Time Series From Production Data Using a Power Curve Model and Quadratic Optimization

Wind Energy, Volume 29, Issue 8, August 2026.
ABSTRACT Accurate, time‐resolved installed capacity data are crucial for forecasting and analysing wind‐power production. The time series of installed capacity is often only approximately known in regions with rapid wind power development. Public wind power databases may only be updated yearly and installation dates may not be differentiated within ...

Ecohydrologic Processes Modify Urban Rainfall Intensification in Land‐Atmosphere Simulations

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Ecohydrologic processes influence urban water and energy cycles including convective rainfall. Coupled land‐atmosphere models, however, lack fine‐scale representation of urban ecohydrology processes. This study integrates these processes into ensemble land‐atmosphere simulations to assess changes in convective rainfall in Milwaukee, Wisconsin.

Moist orographic gravity wave drag parameterization reduces the bias of summer rainfall over the Tibetan Plateau

npj Climate and Atmospheric Science
Summer precipitation over the Tibetan Plateau (TP) significantly affects the regional and global climate. In this paper, the orographic gravity wave drag (OGWD) parameterization is revised by incorporating the moisture effect of saturated air into the ...

Double‐ITCZ Bias Reduces Southern Hemisphere Influence on Tropics via Oceanic Pathways

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Many coupled climate models exhibit an Intertropical Convergence Zone (ITCZ) south of the Equator in the annual‐mean tropical Pacific that is more pronounced than observed. This bias impacts winds, wind‐driven ocean circulation, including the meridional subtropical cells, and the zonal distribution of waters supplying the equatorial ...

Mesoscale Verification Using Meteorological Composites

Monthly Weather Review, 2004
Abstract Mesoscale models are often used to explicitly predict discrete, highly structured phenomena. Information regarding the ability of the model to predict events as coherent entities is thus a useful statement of performance. Observational constraints are a significant problem, though, as the shape, size, and intensity of any given event are often

Low Cross‐Product Agreement in Global Coastal Marine Heatwaves (1982–2023) and Implications for Trend Attribution

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Coastal marine heatwaves (MHWs) derived from satellite and blended sea surface temperature (SST) products often disagree, but the magnitude and drivers of this uncertainty remain poorly quantified. Using four daily SST products from 1982 to 2023, we quantify agreement at 9,946 global coastal points using two inter‐product intersection‐over ...

Observations of Offshore Low‐Level Jets Off the U.S. East Coast Reveal Systematic Biases in ERA5 and HRRR

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Low‐level jets (LLJs)—wind speed maxima typically occurring a few hundred meters above the surface—are common off the U.S. East Coast and influence many atmospheric processes with societal importance, including cloud formation, aviation safety, and search‐and‐rescue.

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.

An Atmosphere–Land–Ocean Coupled Global NWP System: Performance Evaluation for Potential Operational Use

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract This study assesses the influence of ocean–atmosphere coupling on short‐ and medium‐range forecasts of the July 2024 Indian summer monsoon using the newly configured coupled NCMRWF Unified Model (C‐NCUM). Forecasts are evaluated against the operational atmosphere–land model (NCUM) using GPM rainfall, OSTIA SSTs, and reanalysis‐derived moisture

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 ...
