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

Rolling DICE to advance knowledge of land–atmosphere interactions
The Diurnal land–atmosphere Coupling Experiment (DICE) examines land–atmosphere interactions. Findings show land‐surface models struggle with daytime evaporation without representing dead grass layers; coupling land and atmosphere models improves the accuracy of surface fluxes but compromises variables like temperature and humidity.

Spatial and temporal structure of the fog life cycle over Atlantic Canada and the Grand Banks
The relationship between fog occurrence and atmospheric and ocean surface conditions is explored from a 71‐year climatological analysis covering a broad range of spatial and temporal scales of marine fog over Atlantic Canada and the Grand Banks of Newfoundland, Canada. We find that the ocean surface plays a key role as a necessary boundary condition in

Analysis of the complex role of trees in street canyons using a large‐eddy simulation model
Our large‐eddy simulations with high spatial resolution (down to 1 m) show a significant improvement in thermal comfort in shaded areas beneath trees during the hottest part of the day and just after sunset. However, they also highlight a drawback: in narrower streets, PM10$$ {\mathrm{PM}}_{10} $$ concentrations more than doubled compared with areas ...

Air–sea–ice interactions in Isfjorden, Svalbard: An atmospheric perspective
Due to its location and complex topography, atmospheric conditions in the Isfjorden region in central Svalbard are highly variable in space and time. Using new high‐resolution atmospheric reanalysis data, we show that near‐surface wind channeling and cold air advection strongly impact the winter heat extraction from the fjord, comparable to the effect ...

The evolution of wind gusts is difficult to observe because gusts are short‐lived phenomena that can originate at higher altitudes. During the Field Experiment on Sub‐mesoscale Spatio‐Temporal Variability in Lindenberg (FESSTVaL), novel ground‐based remote‐sensing methodologies were applied to measure wind with Doppler lidars in order to provide the ...
