04-19-2022-1434 - US researchers called the low pressure system a “bomb cyclone” because it formed so rapidly, undergoing the delightfully termed “bombogenesis”.

What about the Arctic?

A similar weather pattern occurred last week in the Arctic. An intense low pressure system began forming off the north-east coast of the United States. An atmospheric river formed at its junction with an adjacent high pressure system.

This weather pattern funnelled warm air into the Arctic circle. Svalbard, in Norway, recorded a new maximum temperature of 3.9º C.
