Sentences with phrase «replaces warmer air»

land breeze — cool air above land during night is pulled out to replace warmer air rising over water.

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.

This is the boundary between warm air and cold air and is indicative of cold air replacing warm air at a point on the Earth's surface

Whereas today most British Columbians burn natural gas to heat their homes, 15 years from now many of those furnaces will be replaced by high - efficiency heat pumps — electric units that transfer heat from outside your home to warm the air indoors, and work even when it's much cooler outside.

Once you take it out of the bowl the water inside the glass is replaced by air, which then is warmed, too.

Now, more and more often, the jet stream seems to weaken and allow cold Arctic air to flow south, with warm air flowing north to replace it.

The W140 cost 25 % more than the W126 that it replaced and featured double - pane window glazing, self - closing boot lid and doors, electric windows with a jam - protection feature (lowering when encountering an obstruction), rear - parking markers in the US (which appeared on the rear wings when in reverse), and a heating system which emitted warm air while residual energy was available after the engine was turned off.

If your car's AC stops being able to blow warm air and you find coolant leaks, you may need to replace the connector hose heater control valve.

Two identical parcels of air in terms of # molecules, one rises and expands on cools the other to replace the former drops and compresses and warms.

cold front — when cold air moves towards, and replaces, warmer air.

This warm air rises from the cookie to be replaced by cool air.

By contrast, there is quite a lot of data now telling us that CO2 is not a climate driver: We did the experiment of adding a large slug of CO2 to the air and the temperature stopped rising in 1997, the stratosphere stopped cooling in 1995 and the oceans showed no warming down to 700m when we replaced guesswork with accurate measurement in 2003.

The warm air raises up because it is lighter and cool air replaces it.

Air on the real Earth is always moving up, down and sideways as warmer air seeks cooler venues and cooler air circulates back to replace it and be warmed in tuAir on the real Earth is always moving up, down and sideways as warmer air seeks cooler venues and cooler air circulates back to replace it and be warmed in tuair seeks cooler venues and cooler air circulates back to replace it and be warmed in tuair circulates back to replace it and be warmed in turn.

In contrast, opening windows and allowing for wind - driven cross-ventilation can rapidly remove a lot of warm indoor air and replace it with cooler outside air.

The same happens with convection when conditional instability is considered because moist air releases latent heat and effectively becomes warmer than the dry air it replaces it higher levels.

This unusual flow pattern allowed cold air to spill southwards and be replaced by warm air moving poleward.»

HFCs are synthetic chemicals, primarily used in refrigeration, air conditioning and foam blowing, which were commercialized to replace the high - global warming potential zone - depleting chemicals phased out by the Montreal Protocol over the past 25 years.

HFCs are chemicals primarily used in refrigeration, air conditioning, and foam blowing, which were introduced to replace the ozone depleting chemicals phased - out by the Montreal Protocol, despite the fact that HFCs are extremely harmful to the climate with global warming potentials hundreds and thousands of times higher than carbon dioxide (CO2).

We found that electric heat pumps generally use less energy in warm states and have moderately positive economics in these states if a heat pump can replace both the furnace and a central air conditioner.

This rising air is replaced by more warm, humid air from the ocean below.

The principle of the system is to move heavy cold air to prevent stratification, and allow the warmer inversion layer air to replace the colder air near the ground.

I think that pointing to ocean heat content is the best response that can be made to anyone who thinks warming has stalled — surface air temperatures are not the definitive measure of climate change and I'd like to see the habit of treating it like it is replaced by reference to more fundamental measures of change like heat content of oceans (plus land, ice and atmosphere).

If we are going to effectively reduce air pollution and address global warming, we need to shut down the oldest, dirtiest coal plants — and not build new ones to replace them.

While the DA was replaced by low sea level pressure (SLP) over the Arctic Ocean in July, high pressure returned over the Beaufort Sea in August coupled with low pressure over Siberia, helping to compress ice towards the pole and bring warm air into the Arctic.

In July, the Arctic Dipole Anomaly (DA) pattern that was dominant in June (which promotes clear skies, warm air temperatures, and winds that push ice away from coastal areas and encourages melt) was replaced by low sea level pressure (SLP) over the Arctic Ocean, leading to ice divergence (ice extent «spreading out») and cooler temperatures.

With a greater focus on carbon dioxide emissions and global warming, federal and state governments have provided incentives for individuals to upgrade and replace existing heating, ventilation and air conditioning (HVAC) systems with newer, energy - efficient units.
