A case study of boundary‐layer development downstream of a small, remote island

Quarterly Journal of the Royal Meteorological Society, EarlyView.
An empirical investigation into fog–island interactions near a remote North Atlantic island during July 2022 is carried out using land‐ and ship‐based observing systems. During the case study, surface winds steadily decreased (a) while strong diurnal forcing caused strong spatial gradients in surface temperatures across the observing region (b ...

Effects of Inflow Turbulence on Structural Deformation of Wind Turbine Blades [PDF]

arXiv, 2020
The present investigation provides the first field characterization of the influence of turbulent inflow on the blade structural response of a utility-scale wind turbine (2.5MW), using the unique facility available at the Eolos Wind Energy Research Station of the University of Minnesota.

Data assimilation errors due to incomplete accounting of balanced versus unbalanced moisture

Quarterly Journal of the Royal Meteorological Society, EarlyView.
We investigate data assimilation strategies with moisture and assess the impact of accounting for moisture's balanced and unbalanced components. To illustrate the main ideas, examples are presented using a simple model consisting of linear, moist, shallow‐water equations with stochastic forcing.

Two archetypes of tornadic quasi‐linear convective systems in the United Kingdom: Relevance of horizontal shearing instability to vortexgenesis and maintenance

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Two archetypes of tornadic quasi‐linear convective systems with and without horizontal shearing instability. Modeled surface precipitation rates (mm ·hr$$ \cdotp \mathrm{hr} $$ −1$$ {}^{-1} $$; colored) and absolute vorticity (contours every 3×10−3$$ 3\times 1{0}^{-3} $$ s−1$$ {}^{-1} $$; dashed when negative) after vortexgenesis from the model domain.

Investigating the association between meteorological factors and the transmission and fatality of COVID-19 in the US [PDF]

arXiv, 2020
A novel coronavirus disease (COVID-19) is sweeping the world and has taken away thousands of lives. As the current epicenter, the United States has the largest number of confirmed and death cases of COVID-19. Meteorological factors have been found associated with many respiratory diseases in the past studies.

Regional to large‐scale mechanisms controlling intraseasonal variability of low‐level clouds in Western Equatorial Africa

Quarterly Journal of the Royal Meteorological Society, EarlyView.
(a) Location map with the 26 stations as yellow squares superimposed on the topography in metres above sea level. Correlations between intraseasonal variability of the stratiform cloud cover over Western Equatorial Africa (WEAisv) and (b) observed low‐cloud fraction (LCF), (c) ERA5 LCF at the same location as stations with the same missing entries, (d)

Monitoring of a multi‐span prestressed concrete bridge using satellite interferometric data and comparison with on‐site sensor results

Structural Concrete, EarlyView.
Abstract Satellite‐based Synthetic Aperture Radar Interferometry (InSAR) represents a promising supplement to traditional Structural Health Monitoring (SHM) methods, offering a non‐invasive solution that eliminates the need for sensor installations and provides extensive spatial coverage.

A note on the use of the word 'likelihood' in statistics and meteorology [PDF]

arXiv, 2003
We highlight the different uses of the word 'likelihood' that have arisen in statistics and meteorology, and make the recommendation that one of these uses should be dropped to prevent confusion and misunderstanding.

Segmentation for radar images based on active contour [PDF]

arXiv, 2009
We exam various geometric active contour methods for radar image segmentation. Due to special properties of radar images, we propose our new model based on modified Chan-Vese functional. Our method is efficient in separating non-meteorological noises from meteorological images.

Detection and tracking of deformable moving structures, application to meteorology [PDF]

, 1999
L'objet de cette thèse est la détection et l'estimation du mouvement d'objets déformables. Ce travail a été appliqué à l'imagerie satellitaire. Nous nous sommes particulièrement intéressés aux images infrarouges météorologiques. Sur de telles images, les structures en mouvement sont les nuages.
