The phrase "air fluctuation" is correct and usable in written English.
It can be used in contexts related to physics, meteorology, or any discussion involving changes in air pressure or movement.
Example: "The study focused on the effects of air fluctuation on local weather patterns."
Alternatives: "air movement" or "air pressure variation".
Aqua's suite of instruments include devices that will measure cloud properties, the wetness of land surfaces, land and sea temperatures, humidity and temperature at different levels of the atmosphere, the properties of particles in the air, fluctuations in solar energy absorption and many other parameters.
Precursor methods include changes in strain rates, seismic wave speeds, and electrical conductivity; variations of radon concentrations in groundwater, soil, and air; fluctuations in groundwater levels; electromagnetic variations near and above the Earth's surface; and seismicity patterns.
This noise is primarily due to possible fluctuations from the plasma outside the RBC membrane and residual uncommon path vibrations and air fluctuations in the interferometer.
The water cap served to minimize the refractive index mismatch at the interfaces, to increase the signal-to-noise ratio by suppressing background noise arising from thermal gradients and air fluctuations, and to prevent direct contact between the probe and the sensing surface.
Due to guideway deflection and unavoidable air gap fluctuation, the car body as well as levitation frame is set to oscillation.
Since, the guideway profile has in general irregular and unavoidable air gap fluctuation in levitated vehicle, the guideway unevenness acts as an additional input as the relative movement of the suspension system is modified on account of these factors.
The use of geothermal energy and phase change materials (PCMs) in the construction systems are an opportunity that may attenuate indoor air temperature fluctuation as well as overheating risk.
However, the scale effects of air entrainment, fluctuation pressure and vortex structure call for further investigations in order to make the results of experiments serve as scientific references for practical engineering.
The results reveal that both the air gap fluctuation and the cabin CG (center of gravity) vertical acceleration are strongly affected by the vehicle speed and guideway irregularity, but only slightly affected by the vehicle mass.
Moreover, SMC based on the Kalman filter considerably reduces the air gap fluctuation and cabin CG vertical acceleration responses, and the efficiency of the adopted control methodology is demonstrated even at higher critical speed conditions.
