Earth Day photos

By: Dr. Jeff Masters, 7:02 PM GMT on April 21, 2008

Tuesday, April 22, marks Earth Day. As has been my tradition, on Earth Day I share some of my favorite photos wunderground users have uploaded over the past year. The Earth's atmosphere is a fantastically beautiful and complicated creation, and I thank all of you who took the time to share the spectacular things you've seen with the rest of us!

I'll be back Wednesday to talk about the demise of this year's La Niña.

Small aurora that started right at sunset tonight. Stayed just a stream for most of an hour. Hopefully we will see more in the next few days. You can see more Northern Lights photos in my folder here and at my web site www.northpolegallery.com

Reader Comments

Moderate risk of severe weather for today...although we need to pay attention to how much energy this morning's storms take out of the atmosphere.

ATLANTIC OCEAN...
A DEEP LAYERED LOW IS OVER THE W ATLANTIC WITH A 1010 MB SURFACE
LOW NEAR 30N75W AND AN UPPER LEVEL CENTER NEAR 30N74W. A
SURFACE TROUGH EXTENDS SW TO THE CENTRAL BAHAMAS NEAR 24N75W.
SCATTERED SHOWERS ARE E OF THE SURFACE LOW FROM 28N-33N BETWEEN
72W-75W. ANOTHER 1011 MB LOW IS OVER THE W ATLANTIC NEAR
27N70W. A SURFACE TROUGH EXTENDS S TO HISPANIOLA NEAR 20N70W.
SCATTERED MODERATE CONVECTION IS NE OF THE LOW CENTER FROM
28N-30N BETWEEN 67W-69W. ANOTHER DEEP LAYERED LOW IS N OF THE
AREA OVER THE CENTRAL ATLANTIC WITH A 1007 MB LOW CENTERED NEAR
34N48W AND AN UPPER LEVEL CENTER NEAR 35N47W. A SURFACE TROUGH
EXTENDS SW FROM THE SURFACE LOW TO 24N53W WITH NO
PRECIPITATION. A 1023 MB HIGH IS OVER THE E ATLANTIC NEAR
31N27W. EXPECT THE TWO SURFACE LOWS OVER THE W ATLANTIC TO MOVE
SE OVER THE NEXT 24 HOURS WITH LIGHT CONVECTION. ALSO EXPECT
THE SURFACE TROUGH OVER THE CENTRAL ATLANTIC TO MOVE E WITH
SCATTERED SHOWERS.
C.A. It is just too early as far as conditions go for anything to develop in that low's current location. SSTs and atmosphere just aren't ready yet. If this were 05 or last season that may have been different story but conditions just aren't there yet. There isn't enough ocean warming to support even sub-tropical development yet. Note post 496 and how air temps in the Bahamas are 5-10 degrees lower than what would be expected to support tropical development. Same here on the FL east coast. Morning lows are still in the 60s along the coastal areas. When you start seeing lows of 78 or so along the beaches here, that is the time to really start watching. Until then, expect everything to remain "cold core" unless it is in western caribbean.

I did'nt say anything would develop, The possibility is however there. Though it is very slim. This season though indeeed is likely going to be alot more busy than 07-06....Conditions are setting up slowely but are setting up for a very active season, Agree?
Anyways, Folks i am off, Untill later.

(Yes, The name is going to be changed, As hurricane season is upon us.) Also i will have a blog update later, Check in about 6:00PM EST.
hi all!

whens the blog coming today?
No CaneAddict it will likely be a quieter hurricane season than 07. The SST's are too cool this time of year. Heck I'd be shivering cold if I was going for a swim north of 15N...

It still looks as if that low could get cut off. And, with the high to its n and nw, it looks as if it might make a slight move to the s or sw. And, in a few days, with the other front coming through, my guess is, that it'll still get swept up and out to sea. But, it does look a little interesting.

Good Afternoon Everyone.

Doesn't take long to warm things up does it StormW.
C'mon Dr M, longing for that next blog! LOL Should be interesting to see what he has to say about el nino/la nina.

That was one heck of a storm, man did it get its act together quick!
I missed the whole ENSO discussion in here yesterday. Was it anything different than what was on the ENSO report saying that neutral conditions are modeled in the heart of the season?
I think a lot of ppl forgot about Humberto in '07. Record setting storm.
StormW, heating up quick now with all the sunshine!
Looks like the lows are consolidating to one entity-seas are already up from 1' mush to 4' power chop in 6 hours. If this does develop, could see some minor beach erosion from sustained noth winds over 25knots.
Wow...what crap news.

That means another year without major cane activity.

What happened to global warming....BS is everywhere


I'm thinking that neutral years are more active, or are are more potentially active, than La Nina years themselves...
I agree flood the neutral seasons are more dangerous
WHAT ARE THEY SAYING IS IT GOING TO BE A VERY SLOW HURRICANE SEASON?

demise of this year's La Nia.

Wow...what crap news.

That means another year without major cane activity.

What happened to global warming....BS is everywhere.


We've heard from whirlwind before: any season that doesn't destroy a lot of roofs is a bad year for him (he's a roofer in So Fla).

So it appears like:

1. Quiet year = bad for him
2. Active year = good for him
3. Active year that destroys his house = karma

(Be careful what you ask for...)

Fortunately, I've got him blocked, so won't see his replies...

Wow, Where do you get this information? Are you totally discounting Dr. Grays predictions? As someone else mentioned within 10-12 days the TCHP can change remarkably, As can the water temps. Just because they are cool now doesent mean there going to stay this cool, The cold fronts that are still dipping down as far as South Florida is what is currently keeping SST's from warming up. As the fronts stop, SST's will rise quite rapidly.

No, Don't bother to take the comments from "whirlwind" into consideration. He is a troublemaker. Either way whether a neutral or "La nina" season it will be a very active season. If it becomes a neutral season that could mean more activity than expected, On average Neutral season produce the busier seasons.

And weaker A/B high


If i have this correct that means bad news for the East coast, As the high won't be able to kick much out to sea, correct?
I have a feeling the TCHP in the caribbean is going to jump up alot within the next few weeks...leading up to the start of the hurricane season, After viewing the loop StormW posted, Within one day from the 20th to the 21st the TCHP jumped up quite a bit.

Its not that simple....This can also add to TC'S turing away from the eastcoast depending on were it sets up.There are many factors involved in whats steers a tropical cyclone.
There are a lot of things indicating an active season,and higher risk for the east coast,but still way too early for absolutes,so many things can change between now and hurricane season.

Small favor, catadjuster, please stop yelling in here. As for the season, the forecast is for somewhat above average (depending on your point of view)
Floodman I am sorry wasn't trying to yell. but thanks for the info.
Sheri
CA: Thank you for the answer. I put whirlwind on ignore anyway.

Floodman has very sensitive ears
yesterday the gomex was 71 by me, today it's 75 SRQ,WFL
15NW with lots of gusts --maybe I am more aware of things since I am here all the time, but I just don't remember SO much wind.
No waves, worse NO rain --getting dry out east of I75. Everyone wants to re-seed their pastures, but we need rain
4/29 just heard about a cold front 4/29 that might bring some long board waves to the WFL coast? hummmmm
shoot I think I put everyone to sleep --back to the kitchen w/me
