Assessment of the half-century evolution of mechanisms controlling the heat exchange between high and midlatitudes in the annual cycle

Explosive cyclogenesis in the northeastern part of the Atlantic Ocean

“…It is known that the EAO action centers are shifted to the southeast relative to the NAO centers and, thus, the prevalence of the positive EAO phase can result in the cyclonic activity intensification in the eastern part of the North Atlantic and in the cyclone trajectory shift. The considerable shift of atmospheric action centers in the North Atlantic to the east in the beginning of 1997 is also noted in [2].…”
