The key ingredients for a storm to undergo bombogenesis are an unstable atmosphere, temperature differences and high-speed winds in the upper atmosphere.
It’s hard to get accurate measurements, but a nationwide network of more than 8,000 volunteers with rulers and specific standards reports after every storm.
The winter solstice is past, but bundle up – January is when winter really arrives in many parts of the Northern Hemisphere.
