~ ENSO plays weather maker along with dwindling sea ice extent
~ Extra 2015-16 snowfall a major role in twisting jet stream
~ 2016 warmest consecutive year in history known since beginning of March, but not official till January 2017
~ 2008 Big Blue repeat, cloud seeding theory confirmed yet again.
The sun is of course a giant thermometer, not only a source of energy. Notice apparent lack of sunspots didn't cool anything though.
Arctic deflated sun as seen through many atmospheres. The sun and Earth atmosphere are telling how hot it is anywhere on our planet. The same sun taken in the tropics at the same altitude would look a whole lot rounder.
Rare near dead center lone sunspot is the signature event of this spring. Can you tell which suns as posted above were upright?
NOAA essentially confirmed the large warming of the stratosphere which was seen as unbelievable sun disk expansions, especially with sun shots captured at higher elevations. The latest bit of cooling was equally caught recently with the sun returning to more normal vertical diameters.
The upper troposphere and stratosphere accounts to about 40% of sun disk refraction.
Arctic General circulation projections:
2CTNP left with the largest wobbling like a top over the Canadian Arctic Archipelago. The Jet stream more or less similar to spring fading away along where the coldest land of sea surfaces are.
Consider 3 large geophysical events, very strong El-Nino quickly replaced by La-Nina, the apparent vanishing clouds and a much warmed cloudy winter preceding a cloudless spring. Top this with a huge chunk of sea ice melted once again and 2016 should be remembered as a wonderful hot summer where most people live, especially for those appreciating heat waves, but a disaster where the climatic systems are particularly vulnerable. The weather weirdness factor will thus increase in ways not so kind to all. WD April 24 2016
