Tornadoes are generally defined as rotating columns of air characterized by small size, axisymmetry and short duration.
A binary diagram of the δ13C (CO2) versus 1/[CO2] for São Vicente, Brava, and Fogo data is explainable with two geochemical end-members: air, characterized by δ13C CO2) = −8.0‰ vs. VPDB and [CO2] = 400 ppm and biogenic CO2 (Figure 7).
Given the complex mixture of PM in ambient air, characterizing the biological mechanisms through which PM harms human health is challenging, especially because multiple mechanisms are likely to be operative across the range of health outcomes associated with exposure to PM.
Alongside, wet and warm air masses characterized by strong air-sea interaction from the surrounding oceans, possessing d-excess value of ∼10‰ also play a role.
Plein-air painters characterize much of the Impressionist genre.
Out of the 177 air toxics available through NATA, we examined the distribution, variability, and correlations of 37 air toxics characterized as having neurological, developmental or endocrine-disrupting effects by one of the previous studies [ 17– 19] or the US EPA [ 20].
Snakebite -- Flat tire caused by riding without sufficient air pressure; characterized by a double puncture.
Atmospheric turbulence, small-scale, irregular air motions characterized by winds that vary in speed and direction.
Structural changes as a result of heating (400 850 °C) of the nanocomposite coatings in air were characterized using micro-Raman spectroscopy.
A novel configuration of hydrogen burner utilizing crossflow injection of fuel jets into swirling combustion air is characterized empirically in this work.
