Which distortion arises when a microwave transmission signal encounters atmospheric temperature gradients?

💡 Explanation

Multipath propagation interference occurs because temperature gradients cause differing refractive indices; therefore, signals arrive at the receiver via multiple paths, summing destructively, rather than a direct, single path which would minimize delay spread.
