And in order to increase airflow into the side mounted radiators the turbulent air that exits from the wheel arches is directed into larger air - intakes ahead of the rear wheels, within the intakes the radiators, which are the same size as those in a 650S, have been tuned through four - degrees to increase efficiency.

Turbulent and disruptive air built up within the front wheel arches is accelerated out through the opening in the back of the front wheel arches.

This is the world's first draught - stop system that enables different comfort levels to be selected for two occupants, as the driver and passenger can individually pivot the units to the centre of the vehicle in a flash, thus taming turbulent air flow from the rear.

It's not just a warm - weather car, either, with heated seats and the airscarf warm - air vent integrated into the headrests of the seats, optional ventilated seats (maybe) and the option (yes, for sure) of a small, glass wind - stopper that slots between the rollover bars to stop turbulent air hitting people in the backs of their heads.

In place of exhaust pipes, there are rear vents that help to channel turbulent air from the rear wheel arches into the vehicle's wake, as well as a rear diffuser.

There's also Airguide, a new draught - stop system consisting of pivoting transparent plastic layers attached to the reverse of the roll - over bars — the driver or passenger can swing them to the centre of the vehicle in a flash to tame turbulent air flow.

Whether the installation represents the turbulent journey associated with cancer diagnosis or the infinite life of plastic garbage in our oceans, the installation's place suspended in the air serves as a symbolic reminder that pollution and cancer are issues hanging over all of our heads.

In Gallery II, a large, wall - based sculpture of colorful ceramic disks on rotating arms titled, THIS ONE GOES OUT ACROSS THE SEMAPHORE SPECTRUM, simultaneously takes form as a double solar system model or an antiquated signal device used to communicate turbulent atmospheric conditions to pilots in air or at seIn Gallery II, a large, wall - based sculpture of colorful ceramic disks on rotating arms titled, THIS ONE GOES OUT ACROSS THE SEMAPHORE SPECTRUM, simultaneously takes form as a double solar system model or an antiquated signal device used to communicate turbulent atmospheric conditions to pilots in air or at sein air or at sea.

It is conceivable that turbulent mixing of the air will produce small pockets of air with higher formation rates, in a same fashion as air with different impurities did in the experiments of Enghoff et al..

4) CO2 has a molecular weight of 12 + O2 = 44 so it 50 % heavier than air but that is not enough to cause it separate out, particularly in the turbulent conditions of the troposphere.

Professor Giles Harrison, who led an international research team including scientists from the University of Reading's Meteorology department, the Met Office and the European Centre for Medium Range Weather Forecasting, said: «The sky is often full of clues to weather changes, and asperitas provides distinctive visualisation of complex and turbulent air motions in the lower atmosphere.»

So while the general idea of turbulence in air is correct, your calculation underestimates the tendency for turbulent flow.

Using the Reynolds number above in your calculation, you can see that turbulent flow in air would happen (at a height of 1m above ground) at a velocity of 0.0315 m / s.

One of the most important factors in cloud dynamics, for example, is entrainment, which is when convecting clouds take environmental air and fold it into themselves as they are rising — a turbulent exchange of air between clouds and their environment.

Turbulent mixing of warm air downward likely more common in recent years due to roughness changes, urbanization, sensible heat flux from warm, dark, irrigated vegetation etc..

One would expect this bottom layer to be thin and the thermal lapse to be small — the air above this turbulent bottom would be nearly uniform in temperature in time.

Personally, I don't think the difference between turbulent and laminar flow is all that significant for this issue: In either case, you're going to be mixing air of one temperature («outside») with air of another («inside»).

But a source of great complexity in our spinning, turbulent, inhomogeneous air is the fact that it is largely heated from below, differentially by latitude, by surface properties, by cloud cover, and by time of day and time of year.

Weather in the boundary layer is quite similar to the rest of the troposphere, but it's generally windier (more «turbulent») and the air tends to have more water content.

They are calculated as daily turbulent air - sea fluxes over global oceans with a spatial resolution of 0.25 ° in longitude and latitude.

Variations in SST due to variations in heat transport by ocean currents or diffusion into the thermocline are neglected while contributions by changes in evaporation, turbulent transfer, and surface radiation are estimated as being proportional to the anomalous air - sea temperature difference.
