Indeed it is, and can travel rather long distances.
Sudden short duration bursts of transmission coming through on the radio. Usually associated with high pressure air causing funneling of transmissions from a long way away.
Called "ducting" and sometimes the duration isn't so short! Classic example is trying to get London Volmet North on 126.6 MHz when approaching Berry Head from the south when it is blasted out by Santiago Volmet which is circa 400 n.m. away. Usually associated with high pressure/temperature inversion over the Bay of Biscay.
Radio Hams like this though so they can get extra long range on VHF!
