This means the warm air can not mix with colder air to cool it down.

The researchers found that on windy nights it wasn't possible to measure the cooling effects of the green spaces beyond their boundaries as there was too much turbulent mixing of the air; but on calm warm nights they estimate that a network of green spaces of around 3 - 5 hectares each situated 100 - 150 m apart would provide comprehensive cooling for a city with a climate and characteristics similar to London.

Zhou says the warming was caused primarily by vertical mixing of the air, rather than as a direct result of friction as air passes over the turbines» blades: the movement of the turbines is mixing the cooler ground - level air with warmer air higher up.

They say the turbines mix warmer air that sits at their apex with cooler air at ground level.

Tornadoes have hit every continent on the planet except Antarctica, but the vast majority of tornadoes hit in the United States — specifically in the south and southeast United States, or «tornado alley,» where cold air blowing east from the Rocky Mountains can mix to deadly effect with warm air blowing north from the Gulf of Mexico.

Here Becker et al. investigated the impact of convective organization on entrainment — a process in which warm, buoyant parcels of air become saturated with moisture; form cumulus clouds; and mix with cooler, drier parcels of air.

By contrast, when you breath in your nose, the air is warmed, moistened, conditioned and mixed with nitric oxide, which both kills bacteria and works as a vasodilator on the airways, arteries and capillaries.

The stable top of the marine layer, a result of the temperature inversion, prevents any dry, warm air from above the inversion from mixing with the stratus deck.

As we approached what is known as the Antarctic Boundary line where we crossed into Antarctic waters, the colder air and water currents from the south mixed with the warmer currents of the north causing a thick hazy fog.

Guest suites have a trendy design and contemporary styling with a mix of pale and warm toned interiors, drapes and fabrics of vibrant colour, attractive wall - hung art, smart furnishings cleverly spaced on cool tiled flooring and modern amenities to take care of your comfort; features include a private furnished balcony for most suites with sea or marina view, air - conditioning, a private bathroom with hair dryer and amenities, living room with TV (international channels) and DVD player on request, DVD library at reception, sofa bed / armchair, a bedroom (s) with twin beds, writing desk and chair, telephone, night curtain, a kitchenette with 2 - ring hob, microwave, fridge, coffee machine, kettle, toaster, plates & cutlery and table with 4 chairs, iron and board, and baby amenities.

Whilst flowing across the area between the two columns that cold air does not warm up by compression despite falling in height because it remains in contact with stratospheric air with which it can freely exchange energy by conduction and mixing.

The warmer air evaporates more moisture, but it does so across the entire ocean, and this moist air mixes continually with the air above it, so * all * the air is moister.

The article talks about how the warm ocean temperatures, when mixed with cold air from Canada, quickly create a very powerful storm.

It frequently breaks up during the winter, allowing warmer air from lower latitudes to mix with the Arctic air.

Lake - effect snow happens when moisture from warmer lake waters mixes with cold air coming from the north, causing more than 2 to 3 inches of snow an hour.

Reduced mixing with relatively warmer sub-surface waters effectively reduces the thermal mass exposed to the cold Antarctic air - slightly more ice forms.

The large area of warm water exposed thereby warms the air, warm air rises, interferes with trades, mixes with global circulation, and raises its temperature by half a degree.

Still air with either little vertical shear and relatively weak warming of the ground or with so much vertical shear that turbulence occurs and irreversibly physically mixes the air parcels faster than «reversible» adiabatic expansion can keep up favors the «isothermal» pole, although this too is almost never precisely observed.

In moving the heat from the bottom of the tube to the top is causing the lapse rate to become ** more stable ** — cool at the bottom with warm air above is an inversion which inhibits vertical mixing!!

In other words, UHI * is the value of the urban - heat - island effect if wind were not reducing it by replacing warmer air with colder; and NSTI * is the effect of the near - surface temperature inversion if the wind were not mixing up the air near the ground with the air a little higher up.

However, on windy days, I expect the UHI effect to be vitiated by mixing of air from outside the region of the city with the relatively warmed air; and I expect the windiness to reduce the stratification of the boundary layer («mix it up») and thus reduce the cooling effect of the NSTI.

This «counterflow» design will aid in mixing the warm air that tends to raise to the top of the chamber with the cooler air that will tend to settle on the bottom of the chamber.

The Nature study suggests that global warming will mix growing amounts of higher, drier air with ocean clouds over the course of the century, thinning out the clouds and reducing their cooling effect.

The warm air rises, stops the trade winds, mixes with prevailing westerlies, and thereby raises global air temperature.

They stay warm because the glass also prevents mixing with the surrounding air, but the air wouldn't be warm to begin with if it weren't for trapping infrared.»

You can have a long period of cold air at the surface with little turbulent mixing and little energy transfer, followed by a short period of a warm surface and lots of turbulence and energy transfer - ending with a time average of warm over cold, but a time average of upward energy transfer.

Furthermore, in the absence of such warming, ocean mixing would normally be expected to be constantly refreshing the water at the ocean's surface, the place where it meets with air and dissolves CO2.

I live downwind of topography which in interaction with the wind mixes warmer air aloft downwards at night, and my summer minimum temperatures are often 10F warmer than nearby locations.
