<p class="MsoNormal">This study examines the possibility that winter storms developing off the east coast of Asia may trigger storms developing off the east coast of North American and vice versa. We focus on one point off the northeastern coast of North America
and another off the northeastern coast of Asia where relative vorticity and height fluctuations are large. The starting point was identifying the 100 most prominent vorticity maxima at 500 hPa at each of these points during sixty 150-day cold seasons beginning
on 1 November of each year from 1958 to 2017. Global composites were computed across multiple pressure levels from these events, spanning 25 days before to 25 days after the time of a relative vorticity maximum. This allowed for observation of the disturbance
from 1000 hPa to 1 hPa. At the time of the vorticity maxima, the composite shows an untilted feature about 5° of latitude (560 km) in diameter extending from 1000 hPa to 100 hPa, decaying rapidly above that. Composites confirmed the existence of the wave pattern,
which travels eastward across the Atlantic with maintained strength after reaching a peak off the coast of Nova Scotia (at t = 0). It rapidly loses this strength and gains a notable southward component to its trajectory after reaching the European coastline
but still visibly treks eastward across Asia in its weakened state. Upon reaching the Pacific (at 9–10 days), it surges in relative vorticity strength again. This strength is likewise maintained across the North Pacific, until it similarly and significantly
weakens in strength and attains a southeastern trajectory upon contact with the North America, only to reemerge in a week’s time to repeat the pattern once again at 19–20 days, increasing and maintaining strength along the North Atlantic. Similar results are
repeated using height composites, with wave signal location, speed, and strength mirroring that of the relative vorticity composites. Case studies of individual events allow for the indexing and chronicling of the events life cycle.<o:p></o:p></p>
