Title:	Variability of the radiant heating rate at the border between water masses with different absorption properties - a theoretical prediction
Authors:	Matciak Maciej
Abstract:	The spatial distribution of the radiant heating rate (RHR) in an area of seawater absorption change was investigated by means of a theoretical model. It was found that a sufficiently high gradient of the absorption coefficient in a horizontal direction could contribute significantly to the water’s warming. When combined with an absorption increase in the vertical direction, it raised the local RHR value to about one and a half times its value in the adjacent area. Moreover, when solar energy propagated through the water of higher absorption and entered the area of lower absorption, the horizontal component of the absorption gradient resulted in a lowering of the RHR value. The highest obtained spatial differences between the radiant heating rate values was of the order of 10^-2 °C per hour under the conditions of a cloudless sky with the sun zenith angle at 45° and sea surface irradiance value of nearly 700 W m^-2.
