Hotter days mean more evaporation, worsening the impacts of droughts even when there isn't a significant decrease in precipitation.
Water levels are influenced by the amount of evaporation from decreased ice cover and warmer air temperatures, by evapotranspiration from warmer air temperatures, and by potential increases in inflow from more precipitation.
In some areas precipitation increases, in others it decreases, while evaporation can be expected to increase due to rising temperature.]
Just as an El Niño produces a hotter Equator in the Pacific Ocean and generates more atmospheric convection, so there might be a subnormal mode that decreases heat, convection, and evaporation.
And even if rainfall decreases only slightly from today's levels, evaporation typically increases as temperatures rise, so Namibia is likely to become even drier.9 As water becomes scarcer, the range and number of wildlife supported by Etosha and other national parks could decline.9
Even in areas where precipitation does not decrease, these increases in surface evaporation and loss of water from plants lead to more rapid drying of soils if the effects of higher temperatures are not offset by other changes (such as reduced wind speed or increased humidity).5 As soil dries out, a larger proportion of the incoming heat from the sun goes into heating the soil and adjacent air rather than evaporating its moisture, resulting in hotter summers under drier climatic conditions.6
While SRM is seen by many as the «safest» and cheapest of the geoengineering proposals to date, there are risks, including a decrease in precipitation and evaporation.
Evaporation increases with rising surface temperature, decreasing relative humidity, and increasing surface wind speed.
In the tropical Atlantic for example, the paper linked in the post (Wang 2005) describes how a decrease in evaporation causes SST to rise.
Drought is expected to increase in frequency and severity in the future as a result of climate change, mainly as a consequence of decreases in regional precipitation but also because of increasing evaporation driven by global warming1 — 3.
I conclude that the observed global aridity changes up to 2010 are consistent with model predictions, which suggest severe and widespread droughts in the next 30 — 90 years over many land areas resulting from either decreased precipitation and / or increased evaporation.
Although the Middle East is not currently rebounding from an ice age, the scientists say those ancient rebounds have things in common with the way the climate is changing today: Rainfall is decreasing and higher temperatures are causing more evaporation that is drying up the land.
At the local scale, high temperatures may lead to increased evaporation and decreased soil moisture, resulting in an «agricultural drought».

If evaporation contributes only a portion of the cooling of that 1 mm layer (some or even most being attributable to conduction and radiation) then more evaporation would still cause even more cooling of that layer and would still be a mechanism for maintaining or increasing the energy flow to the air rather than decreasing it.
With evaporation being the more powerful effect the rate of energy flow to the air above is likely to increase rather than decrease and the 1 mm deep layer descend and / or intensify despite a warming of the topmost few microns.
So if one increases the rate of downwelling IR (thereby increasing the evaporation rate) then the increase in upward energy flow caused by the fall in the temperature of that 1 mm layer will be greater than the decrease in upward energy flow that will result from any reduced temperature differential between the topmost Knudsen layer and the ocean bulk arising from the application of Fourier's Law.
