    Exploring Shadow Bands

    These mysterious bands of shadow race across the landscape in the seconds before totality. Scientists still don’t fully understand what they are. You can study them yourselves by taking measurements and photographs and come up with your own hypothesis.

    Shadow bands are thin wavy lines of alternating light and dark that can be seen moving and undulating in parallel on plain-coloured surfaces immediately before and after a total solar eclipse. Shadow bands have been noted throughout history.

    In the 9th century CE, shadow bands during a total solar eclipse are described for the first time-in the Völuspá, part of the old Icelandic poetic edda. Hermann Goldschmidt of Germany notes shadow bands in 1820 visible just before and after totality at some eclipses. George B. Airy, the English astronomer royal, saw his first total eclipse of the sun in 1842. He recalled shadow bands as one of the highlights: "As the totality approached, a strange fluctuation of light was seen upon the walls and the ground, so striking that in some places children ran after it and tried to catch it with their hands"

     

     

  2. Wow, that's amazing!  I wanted to ask a question of those who have seen a total solar eclipse.  Something I read about in The Farmers Almanac that stated that you have to see this in person, it can't be photographed.  They mentioned that during totality the air shimmers the way water does when you look down into a swimming pool on a sunny day.  Is this true?  And why can't this effect be photographed?  And can you see stars during the day time during totality?  And the wind picks up, animals/birds go silent, and there is a noticeable drop in temperature.

    That's good advice for most but even though this will hopefully be my first TSE, photography will be a big part of the day for me. I work as a photographer so I'm intimately familiar with my camera gear and can operate it in the dark or under pressure, etc. I plan to have three cameras set up – one mounted to a telescope for close-up views, one with a 300mm telephoto lens for imaging the outer corona, and one with a wide-angle lens to capture the scenery at totality (this one might get axed depending on my viewing site. Hotel parking lot? meh.) With semi-automation and remote shutter releases, it'll be doable. I'm positive that not every shot will be a success... my biggest goal is merely to learn as many lessons as possible so I'm better prepared for future eclipses.

    You can automate the cameras on tripods and let them do all the work while you view it :) I assume you have solar filters on your lenses and such?

    Don't forget we have another total solar eclipse coming up in April 2024 in Buffalo/Erie!

    And we have the Perseid meteor shower the week before the eclipse too!

    310 hours away

    ECM/GFS continue to show back/forth pattern and 7/3-7/5 warm-ish as trough is lifting out and flow goes WSW.

    I wonder when we'll get that big pulse of heat that is happening in the Desert SW right now.  That was in the Near East at the end of May so if it continues eastward we should have near record temps sometime in the middle of July.

    Sure. It's interesting how we are seeing the winter and summer patterns reversed. Notice how December has had the most top 10 record record warmth to start the winter while January showed the least. This is flipped in the summer with June having the least top 10 warmth with July the most.

    October is also a cooler standout compared to the rest of the year in terms of top ten warmth. It may be why we were still able to set a new October monthly snowfall record in 2011 beating 1925, 1952, and 1876.

    I was really surprised by that, as we had no record of accumulating October snowfall going back for many decades.  I wonder if that means that one day we'll actually have a May accumulating snowfall?

    PS how did you like the warm finish to April?  We actually tied the high on 4/16 on 4/29, as it reached 85 here on both days.

  6. During the full forecast Jeff Smith elaborated and said he doesn't expect ANY mixing across western Long Island or any area he has under his 12 inch band, but he expects amounts to be lower across Western Long Island and NYC because of lower ratios and a possible dry slot.  He said temps will not get above 32 from Islip and points west.  He said 12-15 inches for NYC and Western Long Island and up to 24" to the NW
     

     

  7. Lee Goldberg was just on ABC, and even though he mentioned the new GFS he said he favors the Euro and mentioned a few reasons why.  Of course he also said "gut." lol

    He did say that although he favors an offshore track that the storm could still mix right along the coast.  But he favors historic totals for the city because of the set up and the pattern as well as the more reliable and accurate Euro and its resolution.

    Yeah, I mean it depends when you watch as well.  During certain time slots, especially during the winter and severe season, they bring on more experts etc. and show more analysis.

    Yeah, I like their storm coverage much better and WUTV is really nice, except ever since they bought WU they hiked up the prices for third party API by like 4x, so people who want to use the data from the site and save it onto a spreadsheet or use the data on their own site now have to pay a lot more.  Which is disturbing since the data is provided by the NWS for free.

    Yeah, they do stuff like that sometimes lol.  Personally, I think that TWC tries to gear the content more towards the average watcher.  If they went into great detail, (and I wish they would more often), a lot of people would probably tune out since they just want quick weather updates.  I still like watching, don't get me wrong, and there is definitely lots of great analysis from some mets there.  Dave Schwartz was one of my favorites.

    What I don't understand is why doesn't the NWS take a stand for a change and call this kind of stuff unprofessional? I liked it when DirecTV took them off the air for their ridiculous primetime programming.
