The red and blue vertical lines emphasize the months of maximum sensible heat flux and latent heat flux, respectively. (pnas.org)
An increase in the air temperature will throw the system out of balance, through increasing the downward infrared flux and the downward sensible heat flux. (geosci.uchicago.edu)
Radiative heating of the land surface in spring enhances sensible heat flux from the ground («Sensible»). (pnas.org)
