Abstract Enhanced Southern Ocean ventilation in recent decades has been suggested to be a relevant modulator of the observed changes ocean heat and carbon uptake. This study focuses on midlatitude from 1960s 2010s. A global 1/4° configuration NEMO–Louvain-la-Neuve sea ice model, version 2 (LIM2), including inert tracer CFC-12 (a proxy ventilation) is forced with CORE, phase II (CORE-II), JRA-55...

Natural ventilation has played an important role for many low energy-building designs. It has been also noticed as a essential subject to persistently bring the fresh cool air from the outside into a building. This study carried out the computational fluid dynamics (CFD)-based simulations to examine the natural ventilation development of a work area in a public building. The simulated results c...

The purpose of this paper is to evaluate the effects of a building parameter, namely ceiling configuration, on indoor natural ventilation. The computational fluid dynamics (CFD) code Phoenics was used with the RNG k-ε turbulence model to study wind motion and ventilation flow rates inside the building. All the CFD boundary conditions were described. The simulation results were first validated b...

A study was realized to assess the effects of historical and projected future climates on hygrothermal performance cross-laminated timber wall assemblies in 12 Canadian cities belonging several climate regions zones for two cladding ventilation types. Water ingress assembly supposed be 1% wind-driven rain (WDR), airflow rate drainage cavity calculated using local data. The simulation results sh...

[1] We estimated the air‐sea gas transfer velocity for oxygen using 3 consecutive years (September 2003 to August 2006) of high‐quality oxygen measurements from profiling floats in the central Labrador Sea. Mixed layer oxygen concentrations exhibit strong seasonality characterized by biologically and thermally driven evasion during spring/ summer and invasion during fall/winter caused by coolin...

This paper presents the urban wind ventilation mapping from building frontal area index on the example of urbanised city, Hong Kong. The calculations of frontal area index for each uniform 100m grid cell are based on three dimensional building databases at eight different wind directions. The frontal area index were then correlated with land use classification map, and the results indicate that...

The sensitivity of tropical cyclone intensity to ventilation of cooler, drier air into the inner core is examined using an axisymmetric tropical cyclone model with parameterized ventilation. Sufficiently strong ventilation induces cooling of the upper-level warm core, a shift in the secondary circulation radially outward, and a decrease in the simulated intensity. Increasing the strength of the...
