If relative humidity stays constant — and that's what we expect with climate change — and temperatures go up, that means the amount of moisture in the atmosphere is increasing non-linearly,» says Tom Matthews, a climatologist at Liverpool John Moores University in the UK, who led the research.
If the relative humidity is held fixed as the air is warmed, the implied increase in specific humidity of the air will further increase the downward infrared flux, though it might somewhat decrease the latent flux.
Yet,
if the relative humidity is approximately constant, then the C - C equation is quite central.
But
if relative humidity is actually falling (due to water vapour being displaced by CO2 as per Miskolczi) then water vapour may cause a negative feedback.
If relative humidity remains constant, CO2 induced warming would cause increasing specific humidity and a strong positive feedback.
The change in temperature with height of a parcel of air
if relative humidity is less than 100 % dT / dz = g / cp Units = ms ^ -2 J ^ -1 kgK = ms ^ -2 kg ^ -1 m ^ -1 s ^ 2m ^ -1 kgK = Km ^ -1 g = gravity 9.81 ms ^ -2 cp = 1004 Jkg ^ -1 K ^ -1
If relative humidity (RH) of the air were to remain constant as atmospheric temperature rose then the water vapor (q) amount in the atmosphere would accordingly rise.

Obviously, in an actual cloud, the
relative humidity is close to 100 %, but at a grid box scale of 100's of km, the mean
humidity — even
if there are quite a few clouds — will be substantially less.

I'm just a chemist who only understood half your post, but it seems obvious that
if you raise atmospheric temperatures faster than you raise oceanic temperatures,
relative humidity will fall.
The water vapor content of the atmosphere rises by about 50 percent
if atmospheric temperatures were to increase by 5C and
relative humidity remained constant.
Therefore,
if the absolute
humidity were to remain the same as one moves from the coasts to the continental interiors,
relative humidity would actually increase.
If the air maintains the same
relative humidity, you'd expect greater extremes of both droughts and floods.
A reduction in
relative humidity can occur even though water vapor pressure is increasing
if temperature is warming sufficiently.
If the top is at high altitude, it's cold also on the wet side and cold air is in absolute terms always dry, even when the
relative humidity is 100 %.
If» a warmer world will have an atmosphere with more water vapor,» why has atmospheric water vapor declined since satellite measurements began in 1983, and why has tropospheric
relative and specific
humidity declined since 1948?
If we were to wrap the floor joists completely with insulation we would warm up the wood thereby lowering the
relative humidity the wood «sees» thereby lowering the moisture content.
If you actually look at the data for the last few decades... there's evidence for rising specific
humidity in the upper troposphere, but we don't have enough data about
relative humidity to say either way.
One such feedback might exist
if, as assumed in some models,
relative humidity is constant, so increasing the temperature has the positive feedback of increasing the water vapor.
28 Estimated Strength of Water Vapor Feedback Earliest studies suggest that
if the absolute
humidity increases in proportion to the saturation vapor pressure (constant
relative humidity), this will give rise to a water vapor feedback that will double the sensitivity of climate compared to an assumption of fixed absolute
humidity.
If someone is still bothered by this, imagine that the
relative humidity over this patch of the ocean is 100 % and the wind is zero.
If this is a sign of neutral or even negative vapor feedback against increased temperature (and something's dampening the whole system since the climate is relatively stable), with present slight drop of temperatures the
relative humidity should go up again.
If I understand things correctly, the climate models predict
relative humidity in the upper troposphere to be close to 100 % at all times.
Still further, it is conceivable that a colder climate could increase evaporation
if wind speeds were to increase substantially, or this could also happen
if boundary layer
relative humidity were to decrease.
Convection takes parcels of air upwards — and
if this was the only process then the
relative humidity (above the boundary layer) would be at 100 %.
Even
if the temperature of the boundary layer were equal to the temperature of the glacier surface, sublimation could be sustained
if (as is typically the case) the
relative humidity of the boundary layer were less than 100 %.
Changes in
relative humidity don't tell you
if you're getting more or less water vapor.

relative humidity air into an attic, it will condense on any surface less the 48 degrees.
