1.	The short term propagation effects caused by local weather changes are called as ______________(a) Seasonal(b) Temporal(c) Diurnal(d) Noise
Answer» The correct option is (c) Diurnal Explanation: The diurnal variations are short term propagation effects caused primarily by local weather changes and day/night transitions along the signal path. Variations in a refractive index of the atmosphere versus height from the ground contribute to the short term propagation errors.
