Exploration of the use of short‐wave infrared radiances in weather forecasts model Part II: Data assimilation and forecast impact assessment

Quarterly Journal of the Royal Meteorological Society, EarlyView.
The standalone non‐local thermodynamic equilibrium (NLTE) bias correction schemes, utilizing a look‐up‐table and a linear regression method developed in Part I and new quality control procedures for short‐wave infrared radiances (SWIR), were tested within a data assimilation framework.

Climatology of upper‐tropospheric turbulence: Capabilities and limitations of aircraft reports and ERA5 reanalysis diagnostics

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Based on turbulence diagnostics, airlines are willing to avoid up to 15% of the airspace in order to avoid a fraction of turbulence that takes up about 0.1% of the airspace. This study quantifies these three fractions using turbulence reports from commercial aircraft and ERA5 reanalysis diagnostics, revealing that the low and regionally variable ...

Seasonal hindcasts to assess the hazard of meteorological drought over Europe: A multimodel approach

Quarterly Journal of the Royal Meteorological Society, EarlyView.
An application of seasonal hindcasts is presented for assessing the hazard of meteorological drought at the regional scale across Europe. The realism of seasonal hindcasts from five contributors to the Copernicus Climate Change Service is assessed through a rigorous workflow.

Global-scale gravity wave analysis methodology for the ESA Earth Explorer 11 candidate CAIRT [PDF]

Atmospheric Measurement Techniques
In the past, satellite climatologies of gravity waves (GWs) have initiated progress in their representation in global models. However, these could not provide the phase speed and direction distributions needed for a better understanding of the ...

Windows of opportunity in subseasonal weather regime forecasting: A statistical–dynamical approach

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study explores how the atmospheric state at initialisation creates windows of opportunity for improving week 3 forecasts of weather regime activity. Greenland blocking activity increases following Madden–Julian Oscillation phases 7, 8, and 1 and weak stratospheric polar vortex states, revealing patterns exploitable by statistical models.

Impact of small‐scale gravity waves on tracer transport

Quarterly Journal of the Royal Meteorological Society, EarlyView.
We extend a gravity wave (GW) parametrization to calculate the tracer transport due to the GW–Stokes drift and next‐order effects, where the approach is validated by comparing coarse‐resolution simulations with parametrized GWs to high‐resolution, wave‐resolving reference simulations.

Assessing the impact of model biases on subseasonal forecast skill

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Relaxation experiments where the nudging was performed towards bias‐corrected integrations of the same model display significantly improved skill at weeks 3 and 4, particularly in the northern extratropics. This indicates that there is a large potential for improving dynamical subseasonal forecasting skill by improved treatment of model biases.

Stratospheric hydration and ice microphysics of a convective overshoot observed during the TPEx campaign over Sweden [PDF]

Atmospheric Chemistry and Physics
This study examines the cloud microphysical properties and trace gas signatures associated with a convective overshooting event observed during the TPEx (TropoPause composition gradients and mixing Experiment) campaign in June 2024 over Sweden.

A Nexus Analysis of Municipal Wastewater Treatment and Reuse for Agriculture and Sustainability: A Life Cycle Assessment

Sustainable Development, EarlyView.
ABSTRACT The sustainability of the wastewater treatment process relies on the capacity to maximize resource recovery while minimizing environmental impacts and cost. Treated wastewater reuse for agriculture has emerged as a potential solution to build resilience and sustainability.
