Moisture inversions in the central Arctic: Product assessment and long‐wave radiative effect

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study evaluates the integrated water vapour and the vertical distribution of water vapour of state‐of‐the‐art reanalyses, weather forecast models, and ground‐ and space‐based remote‐sensing products in the central Arctic. A particular focus lies on the representation of humidity inversions and the quantification of the long‐wave radiative effect ...

Comparison of two numerical weather prediction models in simulating south foehn in the Alpine Rhine Valley

Quarterly Journal of the Royal Meteorological Society, EarlyView.
ICON outperforms COSMO in simulating a south foehn event in the Alpine Rhine Valley, with improved accuracy in temperature, wind speed, and foehn timing. This enhanced performance likely results from a more accurate representation of surface energy balance and gravity wave pattern on the lee side of the mountain.

The Albedo of Pervious Cement Concrete Linearly Decreases with Porosity

Advances in Materials Science and Engineering, 2015
Pervious pavements have been advocated as a potential countermeasure to the urban heat island effect. To understand if pervious pavements stay cooler than conventional pavements, the albedo of the pervious concrete must be understood. This study measured

Suivi spatio-temporel du couvert nival du Québec à l’aide des données NOAA-AVHRR [PDF]

, 2006
L’imagerie satellitaire dans le visible et l’infrarouge permet de cartographier le couvert nival à grande échelle, ce qui n’est pas facilement réalisable à partir des observations locales conventionnelles. Cependant, en raison de leur résolution spatiale

Assessing the role of urban blue space in summer outdoor thermal regulation in northwestern Europe: A hectometric Weather Research and Forecasting modelling on idealized urban landscape

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Using hectometric Weather Research and Forecasting simulations, we examine how urban blue spaces mitigate extreme summer heat in northwestern European cities through neighbourhood‐scale cooling mechanisms. Results show horizontal advection dominates cooling by mixing cooler air from waterbodies with warmer urban air, providing ∼50W·m−2$$ \sim 50\kern0 ...

Sensitivity of flower trade‐wind cloud organisation to mesoscale atmospheric heterogeneities

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Trade‐wind cloud organisation is insensitive to dynamical and thermal heterogeneities but very sensitive to humidity mesoscale heterogeneities, especially in the cloud layer, where they form moist patches, and not in the sub‐cloud layer. Clouds and rain develop in moist patches, then cold pools develop progressively, initiating mesoscale circulations ...

Parameter investigation for urban surface‐energy balance: A large‐eddy simulation study

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Large eddy simulation modelling is used to investigate the variation in surface‐energy balance (SEB) across an ensemble of morphometrically identical urban geometries. The geometries have the same plan‐area fraction, vegetated fraction, and frontal‐area index, but are unique in terms of building and green‐space layout.

Albedo distribution in Lutzow-Holm Bay and its neighborhood

Antarctic Record, 1997
A method has been developed for estimating the filtered narrow band surface albedo with NOAA/AVHRR data, and has been applied to analysis of the surface albedo distribution in Lutzow-Holm Bay and its neighborhood, Antarctica, in 1990.

Microphysics and interactions of aerosols and fog on the northwest Atlantic Ocean

Quarterly Journal of the Royal Meteorological Society, EarlyView.
In the Grand Banks, aerosol size distributions were bimodal, aerosol and fog droplet concentrations were low, and fogs were shorter (<12 hours). In contrast, near Sable Island, aerosol size distributions had a single broad mode that was likely influenced by continental emissions, corresponding with higher aerosol and droplet concentrations as well as ...
