The atmosphere seemed even heavier when the biting north wind dropped.

Resuscitator (oxygen, pump, ventilator)

Buildings are colonized by airborne microbes that enter through windows and through mechanical ventilation systems.

The meteorological rockets observe temperature, atmospheric pressure, wind etc. at altitudes of between 30 and 60 kilometres.

It forces air through a Venturi force if there's no wind.

Thank the Lord. Without wind the air would be fetid.

Space communications, broadcasting and meteorology

A little air will do you good.

So, the wings pump up air in lemonade bottles, which are on top of that.

I reckon it needs a little airing around here.

Again, you can do that outside and just let it dry in the air.

Mechanical engineers design air handling units to make sure that people are comfortable, that the air flow and temperature is just right.

Therefore, it is the space regime and not the air regime of the State through whose airspace the aerospace object passes incidentally which applies to aerospace objects.

If you look at the x axis of this graph, you'll see that what we commonly want to do which is keeping the outdoors out we accomplished that with mechanical ventilation.

And then about two days later, the wind started to change a little bit, and you could sense that the air was not healthy.

6) air traffic control and those services providing air traffic control services with meteorological information

It's two fans, one which he could turn from outside after he got the vacuum established, and he discovered that if he pulled all the air out of it, the one fan would no longer turn the other one, right?

Climate change and air pollution are also linked through chemical and physical processes in the atmosphere.

(g) Space weather forecasting through solar observations.

So that hole actually makes the air come out and go in.

As the wind comes up, it has to go over the cliff, so as you walk through the air, it goes around your body, some has to go over you.

We pump air under it so the pressure... will force the water back out through the fracture... or at least keep us floating.

Wind slight and fair. Sky obscure....

Mist means liquid droplets of a substance or mixture suspended in a gas (usually air)

travelling through outer space and of using its aerodynamic properties to remain

The direct consequence of this solar storm is that the US military has seen space weather as a combat concern and has built a stronger space weather forecast system.

so that the party style, political style, and the social style can conduct major changes.

Health and environmental impacts generally encompass air pollution ranging from indoor air pollution to that occurring at the local and regional levels, climate change, ecosystem degradation, water pollution and radiation hazards.

In any case, in this regard, it would be more useful to formulate provisions on the innocent passage of a space object over national airspace.

It's a waterborne disease, not something that's in the air.

Air pollution atmosphere

Dust means solid particles of a substance or mixture suspended in a gas (usually air)

As was subsequently learned, Iraq produced bacterial biological warfare agents at Al Hakam with a moderate risk of airborne contamination due to the generation of aerosols.

Mist liquid droplets of a substance or mixture suspended in a gas (usually air)

I've assumed that she lives in an average household with average air pollutant levels.

The packaging shall be adequately ventilated to prevent the creation of flammable atmosphere and the build up of pressure.

In the case of Earth to orbit objects flying through the airspace of foreign States, the two principles of freedom to utilize space and sovereignty of States over their own airspace had to be reconciled.

Existing rules and regulations should be unified to make the flight of an aerospace object possible while it is in the airspace of another State.

Hot air rises, and air is drawn in off the sea to replace it.

Not only that, because you have this convection, you have this rising of the air where it's hot, air is drawn in.
