As the waves strike objects in the atmosphere, the energy is scattered in all directions, with some of the energy reflected directly back to the radar. The larger the object, the greater the amount of energy that is returned to the radar.

WebTEMPER is a two-dimensional (2-D) propagation model and thus cannot model effects such as terrain-influenced out-of-plane scattering, diffraction, and depolarization. With those limitations in mind, TEMPER can still provide useful “first-order” terrain effects for wide-area situations by combining the 2-D results for multiple bearings.
