This numerical study focuses on the fire phenomenology associated with the presence of a composite-type aircraft immersed, at one particular location and orientation, within a large aviation-fuel fire in a moving fluid medium. An extension of the eddy dissipation concept is incorporated, allowing one to investigate the roles of the wind speed and its direction on the fire growth, heat flux dist...

Ground-based telescopes operate in a turbulent atmosphere that affects the optical path across the aperture by changing both the mirror positions (wind induced vibrations) and the air refraction index. Although the characteristics of the atmosphere are well understood in the inertial range, the validity of the homogeneous, isotropic field assumption is questionable inside the enclosure and in t...

Understanding howmoose (Alces alces (L., 1758)) are affected by temperature is critical for determiningwhy populations have recently declined at the southern extent of their North American range.Warm-season heat-stress thresholds of 14 and 20 °C are commonly used to study moose, but the variable response of free-ranging moose to temperatures above these thresholds suggests thatmoosemay bemore t...

Wind, wave and current interactions control the boundary fluxes, momentum and energy exchange between the atmosphere and the ocean, and within the water column. The wind wave effect on the circulation is investigated in a threedimensional time-dependant ocean circulation model. This POM (Princeton Ocean Model) based model is implemented with realistic coastlines in South China Sea and emphasize...

The flux footprint probability distribution (FPD) for the near-surface receptor over a series of sinusoidal hills is evaluated using a backward Lagrangian stochastic (LS) model. The wind and turbulence fields derived from large-eddy simulations under unstable conditions, in which the synoptic wind aligns with the surface-elevation-varying direction, are used to drive the LS model. The character...

[1] In this study, statistical evidence of a possible modulation of the equatorial stratospheric quasi‐biennial oscillation (QBO) by the solar wind dynamic pressure is provided. When solar wind dynamic pressure is high, the QBO at 30–70 hPa is found to be preferably more easterly during July–October. These lower stratospheric easterly anomalies are primarily linked to the high‐frequency compone...
