The increase in temperature after the linear decrease causes an "inversion layer". (http://www.engin.umich.edu/labs/EAST/me589/gallery/CCAQ_f04/mixing_height_inv.htm) explains it well....

"Mixing Height and Inversions
The mixing height is the height of vertical mixing of air and suspended particles above the ground. This height is determined by the observation of the atmospheric temperature profile. A parcel of air rising from the surface of the Earth will rise at a given rate (called the dry-adiabatic lapse rate). ...
