April 22 2024. How much moisture condenses at dew point? All that is in the air, or just what brings humidity below dew point?
I have two questions / suggestions for extra material.
1. I understand the diagram shows the percentage of water vapour that can be carried as a component of air at a given temperature. But what is it a percentage by? Percentage weight, percentage volume, percentage of moles, something else?
2. Are the physiological reasons known why a high dew point is held to be oppressive? Notinasnaid 15:51, 11 November 2005 (UTC)
will a change in air temperature cause the dew point temperature to change as well? —Preceding unsigned comment added by 216.6.155.118 ( talk) 02:22, 4 December 2009 (UTC)
Actually, the Melbourne FL dew point seems to be called more into question than the ones in the Midwest such as Appleton. So will this continue even with a more reliable source? B137 ( talk) 23:05, 29 July 2019 (UTC)

It looks like the 2003 Saudi Arabia dew point record has been recently broken. The dew point temperature was 97 degrees F which is 2 degrees higher than the record. https://twitter.com/US_Stormwatch/status/1691596872903979036 47.12.180.193 ( talk) 23:30, 18 August 2023 (UTC)
In the section on the Arden Buck equation I believe the wrong equation is being used to calculate dew point. The equation in the article is Td = c*γ/(b-γ), but I believe that is only valid for the three constant version. In the 1981 Buck paper he gives the equation for calculating dew point with the additional d constant as: Td = (d/2) * [b - γ - ((b - γ)2 - 4*c*γ/d)1/2]. I stumbled across this because I wrote some code to convert back and forth between RH and dew point, and I found I was getting different answers depending on which direction the calculation went. Switching to the second equation fixed this issue. Madeemay ( talk) 20:01, 29 March 2024 (UTC)
