Air “Bombs”: Gnarly Weather

June 27, 2014

Gnarly Sky Telegraphs Meteorological Air “Bombs.”

Posted this on Tumblr. Sharing here, too. Hey, WordPress, Yahoo is easier:

Mammatus Virga Colorado T-Storm

Gnarly Virga – Mammatus under T-Storm: Windy Downbursts

Gnarly sky under a T-storm.

Rain evaporating in dry air on the way down.

Dramatic, ragged cloud structures.

Potentially dangerous.

Violent wind “air bombs,” gusty downbursts up to 60mph or more possible.

Another view:

“Inverted” view Virga – Mammatus Wind Downburst

Same pic using photoshop feature “inverted.”

No rain.

But evaporating rain on the way down rocked my house, like an air bomb.

Airplane travel impacted into Denver International Airport, where a Severe Weather Warning was issued by the National Weather Service.

Air “bombs” – downbursts – are both gnarly and dangerous.

A sight to see.

And feel.

Blown away.

So, now: seeing is knowing.

Earth’s Great Nor’easter

March 26, 2014

LIVE: Spring Blizzard Cuts Power to Thousands in New England

The Great Red Spot is signature Jupiter.

Jupiter’s giant storm could hold two to three earth-sized planets.

On earth?

We’ve got something, too:

A giant Nor’easter.

Could be the largest storm on earth, as I type this.

Watch this amazing timelapse.

A closer look:

Nor'Easter March 2014

Intense wind field. Nor’easter. 26 March 2014

Blizzard conditions and power outages reported.

Waves exceeded 10 feet.

Wind gusted up to 80 miles an hour, too.

Further evidence of my musing, “Is spring broken?”

Storm had @JimCantore written all over it.

Even other meteorologists called his name:

Meteorologist Cantore answered the bell.

He’s in there, trust me. Scraping snow off the pole:

Here’s his “live” encounter.

Can you imagine if this Nor’easter made landfall?

Its main “punch” remained out to sea.

So, unless George Clooney and the Andrea Gail make a comeback, this is not “The Perfect Storm.”

It’s vast, however.

Easily visible from space.

Probably from Jupiter, with binoculars or a small telescope.

Jupiter’s Great Red Spot is hundreds of years old.

Earth’s Nor’easter will likely “tire” in days.

The result: it’s news, but more weather and science news.

Some amazing science in-progress.

Impossible to pass up.

The visuals, alone.

One day, perhaps, an astronaut’s “live” coverage of The Great Red spot?

Until then, enjoying a great Nor’easter.

From the safety of satellite technology.

Is Spring Broken?

March 18, 2014

On Calendars, Spring Arrives Thursday

Thursday, the start of spring, is the Vernal Equinox:

Days and nights are approximately equal.

America’s weather will be far from balanced, however, per NOAA:

Cold Weather Spring

More cold weather next week. Source: NWS/NOAA

More than half the nation may shiver in below-average temperatures next week.

Weather that is far from spring-like:

Much-needed precipitation is forecast for northern California.

But not the drought-hit central and southern parts of the state.

A lot of key American crops will remain impacted.

Expect higher prices at grocery stores, according to The Wall Street Journal.

Spawning salmon trying to travel dry waterways are affected, too.

As is West Coast recreational and sports salmon fishing.

Look, winter’s already been too long for many.

Social media is full of “fed up”:

For many, Thursday will be spring on a calendar, only.

In real life, all bundled up, you may be thinking one thing.

Spring has a reputation problem.

Spring is broken.

“It’s spring fever. That is what the name of it is. And when you’ve got it, you want—oh, you don’t quite know what it is you do want, but it just fairly makes your heart ache, you want it so!”

What Was Over Atlanta?

February 25, 2014

Cool Clouds Over Atlanta

Meteorologist @JenCarfagno of The Weather Channel said “undulatus asperatus” clouds put on the display that lit up social media:

“Undulatus asperatus translates to ‘roughened waves’ – Looks like an angry sea, doesn’t it?” 

Science writer and meteorologist Anthony Sagliani of Accuweather said a gravity wave packet created the awesome cloud structure:

Here’s another view from Jeremy Campbell of 11Alive.com:

Per Wikipedia:

“Undulatus asperatus (or alternately, asperatus) is a cloud formation, proposed in 2009 as a separate cloud classification by the founder of the Cloud Appreciation Society. If successful it will be the first cloud formation added since cirrus intortus in 1951 to the International Cloud Atlas of the World Meteorological Organization.”

Got my vote.

Neat science.

Cool clouds.
