Provision of pest alerts is associated with better farm performance in Africa
Pest Management Science, EarlyView.Provision of pest alerts on invasive crop pest control in Africa was linked with a higher likelihood of adopting integrated pest management practices, as well as an improvement in crop yield and income. The results suggest that pest alerts are crucial in sustainable pest management strategies against invasive pests. Abstract BACKGROUND Crop pests cause

Quarterly Journal of the Royal Meteorological Society, EarlyView.Using micrometeorological measurements in Brazil at the Amazon Tall Tower Observatory, the scalewise impact of thermal stratification on turbulent momentum fluxes is explored in the roughness sublayer and the atmospheric surface layer. A scalewise co‐spectral budget model developed here revealed that the turbulent momentum co‐spectrum Fwu(kx)$$ {F}_{wu}

Quarterly Journal of the Royal Meteorological Society, EarlyView.This study presents a novel, consistent coupling of two‐moment microphysics (i.e., ice mass mixing ratio and number) with bulk ice optical properties, providing improved accuracy in radiative transfer simulations. The parametrisations, based on the mass‐equivalent spherical radius, avoid uncertainties associated with the effective radius by directly ...

Evaluation of video evidence of possible ball lightning
Quarterly Journal of the Royal Meteorological Society, EarlyView.We analyze images of possible ball lightning that appeared less than 10 m from a video camera. The objects' velocity and estimated brightness all agree with typical eyewitness accounts of ball lightning. Though there is an alternative explanation that the objects were sparks from a power‐line arc, we describe analytical techniques that assist in ...

Quarterly Journal of the Royal Meteorological Society, EarlyView.In this paper, we compare atmospheric water vapour data acquired with lidars during the WaLiNeAs programme with data from the ECMWF ERA5 reanalysis. The WaLiNeAs field measurement campaigns took place in autumn/winter 2022/2023 over the French Mediterranean basin and in summer 2023 near Toulouse.

Weather features drive free‐tropospheric baroclinicity variability in the North Atlantic storm track
Quarterly Journal of the Royal Meteorological Society, EarlyView.We show that synoptic weather features, such as extratropical cyclones, fronts, and atmospheric rivers, contribute to more than half of the total variability of free‐tropospheric baroclinicity in the North Atlantic storm track, despite their limited spatial and temporal extent.

Truncation error analysis for the piecewise parabolic method
Quarterly Journal of the Royal Meteorological Society, EarlyView.This work provides a theoretical error analysis of the well‐established piecewise parabolic method for unforced linear advection problems with non‐constant velocity. Numerical results confirm that merely first‐order accuracy is obtained for deformational flows.

Quarterly Journal of the Royal Meteorological Society, EarlyView.The warm advection associated with a nocturnal jet and high initial temperature profile at 0000 h local standard time turn warm days (WDs) to hot days (HDs). HDs and heatwaves (HWs) have similar physical processes. The slower‐moving upper‐level anticyclone gives HWs their longevity.

On the β$$ \beta $$‐effect in the baroclinic instability of a continuously stratified atmosphere
Quarterly Journal of the Royal Meteorological Society, EarlyView.We solve the quasi‐geostrophic equation numerically to analyze baroclinic instability in a continuously stratified atmosphere. On the β$$ \beta $$‐plane, deviations from classical models alter instability growth rates and modal structures, leading to the emergence of unstable lobes and a stable region at very large wavelengths.
