heat advection

Atmospheric advection of heat or cold: The formation of the false spring phenomenon in the spawning migrations of anuran amphibians (Amphibia, Anura) in Europe

The spawning migrations of four widespread species of anuran amphibians in European fauna (Pelobates vespertinus, Bombina bombina, Pelophylax ridibundus, and Rana dalmatina) were analyzed. In the years with an abnormally early start of the spawning migrations of the anuran amphibians and their passage through a false spring, powerful anticyclones over Central Asia, Trans-Urals or Western Siberia blocked the west–east atmospheric transfer.
