It's official: The weather has been a bit weird this winter. The nation's climate agency says so -- and, in part, explains why.
There is method to the meteorological madness.
And it has served to spread the weirdness around the world, from the American West all the way to Russia, a climate expert from the National Oceanic and Atmospheric Administration said.
The drought parching California; those two snowpocalypses in the South; the unrelenting New England snow; the sopping soaking of the UK; short sleeves on Sochi's snow-hungry slopes.
One single weather event has a hand in all of them, said NOAA environmentalist Bill Lapenta.
"They are associated with that long-wave pattern, so they are connected in that sense," he said.
That "long-wave pattern" is like a whip that got swung in California and has cracked in all the other places.
A big, sturdy ridge of high pressure air has blustered rain clouds away from California, and at the same time, it has pushed the jet-stream way up into Canada.
What goes up...
In reaction to that, the jet-stream has swung back deeper into the South than usual, carrying Canadian cold with it.
Voila. Snow and ice from Louisiana to the Carolinas.
Then it has whipped back up, helping big storms dump snow over the Northeast.
From there, the same jet-stream has crossed the Atlantic and brought weather that flooded Great Britain in the wettest January there in two and a half centuries.
Down the road a bit, at the Winter Olympics, it's practically springtime in Sochi, and it's that same jet-stream dragging in warmth that's boosting temperatures well above freezing.
But it gets even worse.
The jet-stream is moving slower than in past years, which means that all that ugly weather is hovering over places for longer periods, plaguing them with more of its nastiness than usual.
It has weather-beaten people in many parts of the world groaning the same moan: "I've never seen weather like this before."
Are they exaggerating? Maybe not.
Let's have a look at the season's weather, starting with the whip's handle -- in California -- and follow the jet-stream's lash from there.
The dryness in California is making its mark in the history books.
The state grows more than the lion's share of the tomatoes used in U.S. processed foods, farmer Mark Borba brags. This year? Zero, he said.
For the first time in its history, the California Water Project - a system of canals and reservoirs that provide water to two thirds of the people in the state's Central Valley -- set its allocation for all of them to zero.
This pertains to people in the country and in cities alike.
Borba blames it in part on bureaucratic tangles between state and local authorities who decide over the water's release.
But that doesn't negate the fact that there is a water shortage.
His farm gets its water from reservoirs 500 miles to his north. This year, they are running on bare minimum.
Further down the jet-stream, there's been precipitation to spare.
If you haven't been living under a rock, you've heard about or felt the winter ills that have walloped the nation's Southeast.
About two weeks ago, less than 3 inches of snow turned the region's largest city into a gridlocked parking lot, where thousands of motorists sat for as much as 20 hours in their cars, while lows dipped into the teens.
Not being able to deal with snow is no surprise for a region that usually gets iced over every 10 years or so -- although the last such shellacking came three years ago.
Then this week, a second winter storm polished a path of white from Alabama all the way up to Maine.
Not that the Northeast is not used to snow. After all, it's winter, and it's normal there. But the frequency of heavy snows has had leaders in the region huffing for a break.
New York City Mayor Bill de Blasio greeted reporters covering the storm with the line: "Welcome to winter storm six of the last six weeks."
And as New Jersey Gov. Chris Christie said before the worst of the storm hit: "This has just been a brutal winter where it never really has gotten warmer. And so the natural melting away of snow and ice is not happening."
Exaggeration or winter storm exhaustion?
It may have been a long-planned vacation, but after the last storm passed, Christie took off with his family for the warmer latitudes of Puerto Rico.
A previous recent snow-thumping wrecked much of his inauguration celebration -- along with that bridge scandal.
Add to that increased frequency of snowfall a quick CNN weather factoid: Over the last week, the continental United States has had snow on the ground in 49 of 50 states.
