    looks like the big memorial day weekend rainstorm is now gone?

    This is very rare! all record highs and record lows from the same year on the same date! 2002 was such a warm winter and hot spring and hot summer, how did it get so cold so late? Was this the peak of the cold in May that year? Records:Highs:EWR: 99 (1996)NYC: 96 (1996)LGA: 97 (1996)JFK: 95 (1996)Lows:EWR: 41 (2002)NYC: 43 (2002)LGA: 44 (2002)JFK: 42 (2002)

    why cant we dump liquid helium into the oceans?

    wow thanks Don, these are absolutely amazing!

    FYI Since we are talking about plants and flowers, I just got this ultraviolet pass filter to see hidden markings on flowers. More details can be found on this page: http://www.virtualherbarium.org/GardenViews/BeesEyeView.html Bees Eye View Scott Zona, Ph.D., Former Palm Biologist http://www.virtualherbarium.org/images/BeesEyeView5.jpg For some time, biologists have known that bees perceive light differently than humans do. What we see as visible light is a small portion of the electromagnetic spectrum and consists of a mixture of different colored light. Color is determined by the light's wavelength, which ranges from violet (400 nm wavelength) to red (700 nm). We are unable to see other portions of the spectrum, such as ultraviolet or infrared. Bees, on the other hand, see a portion of the spectrum shifted toward shorter wavelengths. Their eyes perceive yellows, greens, blues and purples as we do, but they also perceive ultraviolet (UV) light (180-400 nm). Bees do not perceive the red portion of the visible spectrum. http://www.virtualherbarium.org/images/BeesEyeView1.jpg What we see What the bee sees Because their eyes are so different from ours, we can only approximate how bees see flowers. By using photographic equipment, we can visualize some components of bee vision that are normally invisible to us, namely the reflection or absorption of UV radiation. Plants contain chemicals that either reflect or absorb electromagnetic radiation, including UV, visible, and infrared (which we cannot see but we can feel as heat). Sunlight's UV radiation is absorbed, partially absorbed, or reflected by flowers and can be captured on black and white photographic film or with a digital camera, using special filters. In the resulting photograph, reflected UV appears white, and absorbed UV appears dark. Partially absorbed UV appears gray. The two photos shown here are of a locally common weed, Achmella pilosa, in the sunflower family (Asteraceae). The photo on the left was taken in sunlight without any special filter, using a Minolta DiMAGE 7Hi digital camera. The right-hand photo was subsequently taken with a Wratten 18AUV filter attached to the camera. Typical of the sunflower family, Achmella has the common daisy-type “flower” (inflorescence) that is actually a group of two different kinds of flowers. The outer “petals” are individual flowers, called ray flowers. The central eye is a cluster of small flowers called disk flowers. Together, these two kinds of flowers make up the inflorescence we commonly call daisies or sunflowers. Achmella pilosa exhibits a common phenomenon seen in many Asteraceae: the bull's eye pattern formed by UV-reflecting ray flowers and UV-absorbing disk flowers. The pattern helps bees locate and land on the flowers. Plants need bees to carry pollen from one flower to another, and UV patterns expedite the process.

    I didn't know it covered 250 acres and they have an Alice in Wonderland themed giant topiary going on there? I am partial to the giant March Hare topiary! Question-- why is it called New York Botanical Garden when it's in The Bronx? Why not call it The Bronx Botanical Garden? We have one in Brooklyn and it's called The Brooklyn Botanical Garden.

    last year on this very date it was 42 degrees lol
  9. LibertyBell
    wow it was 42 degrees here last year on this date? now thats cold!
  10. LibertyBell
    100/50 is MUCH better
  11. LibertyBell
    wow 2010 really rocked both spring and summer I want a weather modification device that just puts 2009-2011 on repeat forever. winter 2009-10, summer 2010, winter 2010-11 and summer 2011
  12. LibertyBell
    LMAO
  13. LibertyBell
    you have the perfect username lol
  14. LibertyBell
    No this is perfect! Lots of interesting things happen when the sun comes out. It should only be dark at night....
  15. LibertyBell
    its not just the EC either, check out Texas and the Gulf Coast and Houston, omg it's like Harvey all over again. All the flooding rains they've had down there, they've had the spring from HELL
  16. LibertyBell
    lmao thats funny-- I heard in the mountains you can get snow as late as May? and 100+ degree heat of course in the valleys in the summer? so you get all kinds of weather even if you have to travel a little to get it
  17. LibertyBell
    How is it we're going to have such nice weather next week with zero rain and wall to wall sun and then the pattern will revert back to this just in time for the long weekend?
  18. LibertyBell
    The high is located way too far to the north
  19. LibertyBell
    It's possible but you never know, we have had rainy cool summers before. I envision a humid summer but not very hot maybe a 90 degree day a couple of times a month between June and September with around 10-15 90 degree days in total this year. 15 may be pushing it lol. This is for NYC.

    and this is why we need to chop down the excessive growth in these forests where these fires are occurring. The environment simply isn't there to support the overgrowth and that's why we see these fires. We didn't get these kinds of fires in the 1990s when our springs and summers were much hotter and thats because there was no overgrowth from excessive rains. Consider it population control for trees....

    You like this climate you deserve it. My allergies have gotten much better since I've started spraying and killing every weed in sight.

    Last April and May were fine Chris, we didn't get the wildfire smoke until June. It might be time to start chopping down trees in Canada since more wildfires are now popping up there. There's really no other choice. This year it's western Canada that's burning. I'd much rather have sunny warm weather-- wildfires are a nuisance that can be taken care of by chopping down those trees.

    why does a -pna trough cause warmer weather in the winter and colder weather in spring?
  24. LibertyBell
    sunny and 70s is fine, no need for Ireland weather here

    This is why we're always playing catch up unfortunately. With all that being said, did the models correctly forecast all these marine heatwaves? I know sea level rise seems to be exceeding their expectations so far.
