In a warming world, atmospheric water vapour content is expected to rise due to an increase in saturation water vapour pressure with air temperature.

Thus, if a parcel of air from the surface rises (because of wind flowing up the side of a mountain, for example), it undergoes an expansion, from higher to lower pressure.

First, a mass of air rises, causing it to expand (because of the lower atmospheric pressure).

«If there is low pressure below,» says Sausen, «then air is rising and pollution from planes flying near the top of the troposphere could still rise into the stratosphere.

Vapor pressure is the tendency of solid atoms or molecules on the substrate to vaporize and rise into the air.

The most obvious difficulty is that rising pressure puts the squeeze on the lungs and any other air spaces in the body.

And in fact this is self reinforcing (less sea ice, warmer water, rising air, lower pressure, enhanced storminess).

The Arizona heat is anything but kind to your car's tires, and when the temps start to rise, so does the air pressure in your tires, causing them to wear out faster.

A Catalina eddy is rarely prolonged: as the heat over the deserts causes air to rise, the resulting pressure gradient and increase in the normal onshore winds causes the vortex to dissipate.

Recycled and reproduced sounds overlapped and gave rise to pressure points in the air for visitors to pass through, creating a physical experience of sonic transitions that measures not time but units of space.

The big difference between the last intergalcial period and now is that now the air / ocean temp is rising year round forced inextricably by the relentless pressure of CO2.

Air expands and cools as it rises (to lower pressure) and does the opposite when it sinks (to higher pressure), which is why convection can not make the troposphere as warm as the surface.

The moist air rises until cooler temperatures and lesser pressure cause condensation.

As prices continue to rise and pressure to act on climate change becomes paramount, it is a good time for policy makers to ask if the trend towards air - conditioning indoor spaces is necessary, desirable or even possible.

The declining density gradient with height (caused by gravity) permits lighter, warmer air to rise further away from the surface than can colder, heavier air at the same upward pressure gradient force.

It follows that air rising and expanding into a region of lower pressure need do no work on the surrounding molecules because it simply expands into the additional space made available by the reducing density gradient.

In order to equalize the pressure difference between the the rising parcel and its new environment, air molecules inside the higher - pressure air parcel push out the sides of the parcel.

23 Weather Maps — Low Pressure Areas of low pressure indicate warm airPressure Areas of low pressure indicate warm airpressure indicate warm air rising.

NOWHERE do they talk about AIR PRESSURE, vertical air movement is once mentioned where they state that water vapour rises etc.; no explanation is given whether or not the barometric equation is used (it is, in the models; it assumes hydrostasis and we KNOW that the atmosphere is not hydrostatic!)

Beginning around 1 / 10th the air pressure of the Earth at sea level, Jupiter's atmospheric temperature rises and easily exceeds its predicted blackbody temperature of 110 Kelvin.

Low pressure systems develop under these conditions of rising warm air, which causes frontal systems to move, mixing cold and warm air masses.

Low - pressure systems, in which the air is rising, cooling and condensing moisture as clouds, generally bring unsettled and wet weather.

«Thus, rising air is said to cool or warm adiabatically when its temperature changes are due entirely to pressure changes.

, which enables there to be packets of air in convection which if hotter rise and so colder packets of air displace these (which as he says from meteorology are already knowns), and, as soon as pressure differences introduced ideal gas no longer applies.

15 Low Pressure Systems Winds blow into low pressure areas Warm, moist air will rise, causing cloud formation Weather is usually cloudy orPressure Systems Winds blow into low pressure areas Warm, moist air will rise, causing cloud formation Weather is usually cloudy orpressure areas Warm, moist air will rise, causing cloud formation Weather is usually cloudy or stormy.

Gases with extra heat input might well rise faster, and chinook winds speed up the heating of its air as it comes into greater pressure from the heights, but we are talking about the basic process here, to which all these relate, created by gravity.

Low pressure, high temperature air will always have the lowest density and rise to the top, and because air is a poor conductor of heat the air will stratify hot on top down to cooler on the bottom — an inverted lapse — until one gets to a turbulent zone that turns over diurnally.

The pressure will increase, reducing density of packets of air which will rise.

The point is that the formula for the DALR comes from the assumption that the air heats down low and rises, expanding adiabatically into the air above it (doing work against its increased pressure / density) and cooling as a consequence, a process that only «stops» when there is a uniform lapse between the warm bottom and the actively cooled top.

When the intensity of ultraviolet light from the sun increases, temperature rises in this ozone rich air and weakens the downdraft, lowers the surface pressure and with it the strength of the trade winds that blow across the ocean to the low pressure zones that form over the warm waters that accumulate in the west.

In a convective atmosphere air rising and falling is expanded and compressed by air pressure, this sets up a constant vertical temperature gradient.

As warm air rises this leads to the formation of depressions at sea level, or low air pressure weather systems.

There is a temperature gradient caused by atmospheric radiations — warm air rises, expands and cools in lower pressure at height — but this is just the lapse rate and doesn't create cooler temps at height.

Surface pressure differences from rising and falling air — interacting with the Coriolis force — creates surface wind fields.

Anastassia is entirely correct in that the rising air must be balanced by descending air creating high pressure in the descent arm.

Low pressure develops below rising air and high pressure below descending air.

(The air heated by condensation will continue to rise, but there can't be «vacuum» around the condensation, the colder air at that level will come in to replace any lighter hotter air rising, and colder is heavier so will sink which increases the pressure at the surface.)

Thus a parcel of air into which water vapour is injected will rise without any change in ambient temperature.The reduction of density from surface upwards is what initially reduces air pressure as measured from the surface.

But on the other hand, condensation heats the air parcel and hence causes faster molecular motion and a rise in pressure, which is neglected in the calculations of M&G.

At the surface, increased pressure from injecting water vapour into a parcel of air via evaporation causes the parcel to rise so that surface pressure below it falls.

So on condensation, under the still rising hotter lighter air carrying on doing its thing and perhaps adding new layers, there would be the accompanying volume and temperature decrease of that first previously rising lighter volume now heavier liquid water and added to by the adjacent volumes of heavier colder air flowing beneath the still rising lighter hotter and into the space now available on condensation of its neighbour, which all now being heavier will increase the pressure at the surface as they all sink together displacing the lighter.

ii) If pressure within an air parcel rises then the contents expand to occupy a larger space but that decreases density and weight which reduces pressure at the surface below.

What makes air rise from the surface when evaporation occurs is increased pressure horizontally which increases buoyancy of the less dense parcel by forcing it upward vertically for a reduction of pressure at the base of the column.

At the same time the changed pressure relationship between the vertical and horizontal planes will set up an air flow which serves to bring in new air low down to replace at the surface the air that has risen.

Thus condensation must result in an increase in surface pressure and if the rising column of fresh vapour rich air is continued then the descending column is displaced to an adjacent location as we see all the time in the real atmosphere.

The problem is that the dynamic effect of latent heat (and the associated pressure gradients) can not be calculated considering the rising air parcel alone.
