Sentences with phrase «air pressure waves»

Standing air pressure waves at the mouth of each runner were essentially in phase, while prior manifolds had waves out of phase at low speed, resulting in rumbling noises.

Not exact matches

In hot, thin air, pressure waves move faster.

Kohyama was studying atmospheric waves when he noticed a slight oscillation in the air pressure.

As the shock wave propagates downward, it flows through the moist air and forms a Wilson cloud in the low - pressure trough, underneath the fireball.

In the middle ear, pressure oscillations in the air are transferred via the tympanic membrane (eardrum) and one or three small bones (ossicles) to fluid movements in the inner ear, where the conversion of sound waves to nerve signals takes place.

This membrane translates larger movements from air - pressure waves to smaller, more powerful motions in another structure called the cuticle plate.

Pressure waves generated by explosions or weapon noise, for instance, can rupture air - filled organs, such as lungs.

The NOAA team has set up several arrays of sensors, spaced hundreds of miles apart, that register slight variations in air pressure — a sign of a lengthy sound wave passing by.

During an explosion, instead of cracking with the shock wave's pressure as a harder material might, the air - filled walls move with it.

This is mainly due to indirect determination of the blood pressure from the oscillometric air - pressure wave measurements taken by automatic devices.

High pressure tends to cause sinking air and suppress precipitation, which can allow a heat wave to develop and intensify over land areas.

The scientists hypothesized that the fish's air - filled lungs might be responsible, because the air inside them buzzes and rattles in response to a propagating pressure wave.

He says that any animal with air - filled lungs that vibrate in response to pressure waves «will hear pressure in water whether it wants to or not.»

As the upstroke happens the pressure in the cylinder is now low because the escaping exhaust gases cause a small pressure wave of escaping gas that now opens the reed value and draws in new fuel / air mixture.

It also gets a 3 - zone air - con, touchscreen infotainment system with 8 speakers, aux - in / USB / Bluetooth connectivity, massage function for driver seat, «Easy open» boot lid opener (wave your leg under the bumper), tyre pressure monitoring system, and hands - free parking.

The making of these devastatingly powerful storms is caused by a low pressure air system moving northbound into the Gulf of Alaska while in the zone between, the northern arctic air and subtropical air combine to create a frontal wave as the system begins to move in a south eastward direction toward Vancouver Island.

As the waves recede, the pressure inside the column drops, drawing a stream of air through the same upper opening and providing another impetus for spinning the turbine.

Extratropical cyclones have three stages of expansion: the developing stage, in which an undulating wave develops along the front; the mature stage, in which sinking cold air sweeps equatorward west of the surface low - pressure centre and ascending warm air moves poleward east of the cyclone; and the occluded stage, in which the warm air is entrained within and moved above the polar air and becomes separated from the source region of the tropical air.

Other onboard instruments will record air and sea surface temperature, barometric pressure, relative humidity, wave height and period, and water conductivity.

A tiny wave in circulation / air pressure forms off of the coast of Africa somewhere.

This is only briefly before the air expands due to latent heating to equalize the pressure (Pielke commented on these fast adjustment processes due to sound waves).

The drag - deceleration of the droplet will send out a pressure wave into the air, which when it contacted the surface would constitute the raised surface pressure — the circle of contact would define the pressure footprint.

As the particles pass through a laser beam, the absorbed energy heats the particles and in turn the surrounding air, which sets off a pressure wave that can be detected by a microphone.

«This feeds back to decrease wave height, which reduces movement of air toward the center of the hurricane, increasing the central pressure, which in turn slows the winds of the entire hurricane and dissipates it faster.»

Blocking also leads to extremes developing in air masses, such as cloudless heat waves in the summer and cold clear - skied high pressure centers in winter.

The heat wave was due primarily to a natural phenomenon called an atmospheric «blocking pattern», in which a strong high pressure system developed and remained stationary over western Russian, keeping summer storms and cool air from sweeping through the region and leading to the extreme hot and dry conditions.

It uses small speaker - like ultrasound wave emitters to give the sensation of pressure and texture when you're just waving your hands in the open air.
