A shrinkage of the thermal gradient’s range of temperature by 33ºC.<br />The average temperature of minus eighteen is maintained at the mid point at 5km altitude.<br />The surface temperature is reduced by 16.5ºC and the tropopause temperature is warmed by the same amount.<br />The presence of water vapour therefore reduces the gravitational dry lapse surface temperature of 31ºC to 14.5ºC and raises the tropopause dry lapse temperature from -67ºC to -50.5ºC.<br /><br />Water in all its forms is a moderator of extremes not an amplifier.<br />Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-4142988674703954802.post-80075839396137654302015-01-30T08:36:54.788-08:002015-01-30T08:36:54.788-08:00This supports my contention that radiative loss fr...This supports my contention that radiative loss from within an atmosphere to space causes the amount of energy taken back to the surface in adiabatic descent to be less than the energy taken up from the surface in adiabatic ascent.<br /><br />That reduction in energy returning to the surface then offsets any surface warming effect from GHGs for a zero net thermal effect from GHGs.<br /><br />An enhanced water cycle allows more radiation to space from water vapour and droplets within the atmosphere and thereby weakens convective overturning leading to less atmospheric turbulence rather than more.<br /><br /><br /><br /><br /><br /><br />Stephen Wildehttps://www.blogger.com/profile/07357171106480483956noreply@blogger.com
