  1. When the Arctic becomes ice free, can we expect Summer bombogenesis events?
  2. Don't disagree with the comments about Cruz, but the tasteless topic title cheapens the point.
  3. I don't think I accept the premise that surface temps and troposphere temps move in lockstep, implying that RATPAC is more accurate than UAH or RSS. I fully expect the troposphere to spike later in the year, as a lagged response to record SSTs/Nino conditions.
  4. Tropical convection being a large driver of that?
  5. Where do you come up with this stuff?
  6. I would have guessed larger Hadley Cells until I saw that graph.
  7. I can't remember if this was originally posted here or on another forum. If it was here, then here it is again. http://arxiv.org/pdf/0905.1812.pdf
  8. Or see here: http://spaceweather.com/glossary/sunspotnumber.html Counting sunspots is not as straightforward as it sounds. Suppose you looked at the Sun through a pair of (properly filtered) low power binoculars -- you might be able to see two or three large spots. An observer peering through a high-powered telescope might see 10 or 20. A powerful space-based observatory could see even more -- say, 50 to 100. Which is the correct sunspot number? There are two official sunspot numbers in common use. The first, the daily "Boulder Sunspot Number," is computed by the NOAA Space Environment Center using a formula devised by Rudolph Wolf in 1848: R=k (10g+s), where R is the sunspot number; g is the number of sunspot groups on the solar disk; s is the total number of individual spots in all the groups; and k is a variable scaling factor (usually <1) that accounts for observing conditions and the type of telescope (binoculars, space telescopes, etc.). Scientists combine data from lots of observatories -- each with its own k factor -- to arrive at a daily value. Above: International sunspot numbers from 1745 to the present. [more] The Boulder number (reported daily on SpaceWeather.com) is usually about 25% higher than the second official index, the "International Sunspot Number," published daily by the Solar Influences Data Center in Belgium. Both the Boulder and the International numbers are calculated from the same basic formula, but they incorporate data from different observatories.
  9. How much dampening are you talking about? Any ideas on what the CO2-Hadley Cell link would be?
  10. Now I'm even more confused.... It was just a few years ago that strong trades were blamed for the hiatus, as they transported surface heat down below. Now weaker winds are also causing the ocean to warm, via less mixing and evaporating. By the way, how long does it take heat to transport down 700 meters? It seems like the top 50 meters would be a much better way to measure how much heat the ocean is taking up. As long as I'm asking questions that no one will answer... Weren't the higher SST's supposed to be caused by broad Hadley cells and reduced cloud coverage? There are 3886 free drifting floats around the world. The oceans are 139 millions square miles. This gives us a float on average of every 35,000 square miles. Is there also satellite data to measure SST?
  11. There's a loose correlation there but I don't know what the mechanism would be. The change in TSI isn't enough to explain the pre-AGW, but there could be other causes.
