This is what meteorologist Geoff Masters had to say on August 10th 2014 on a five minute interview on ‘the real news’ on ow the Jet Stream Affects Weather Patterns.......
.....‘Yeah. I was talking about the jet stream, which is that upper-level river of air that tends to control our weather. And the reason it controls our weather is because it acts as the boundary between cold air to the polar side and then warmer subtropical air on the other side. And normally the jet stream flows straight, West to East over our latitudes, which means you don't have a big sort of variation in the weather patterns. But when that jet stream starts to take these big bows, these big excursions like a meandering river, that's when we tend to get really major extreme weather events.
‘In particular, this past winter over the Eastern U.S. and Midwest, this so-called polar vortex episode happened. And what that was: it was a big bulge in the jet stream. It went way far to the south, allowing cold air to spill out of Canada, down much farther south than usual. And on the converse side, over in California you have a compensating ridge, kind of a U-shaped bulge in the jet stream going far to the north, which allowed very warm air from Mexico in the south to bring California its warmest and driest winter on record. So when you get one of these major jet stream undulations, it tends to bring extreme weather of both kinds, both the hot extreme and the cold extreme, and wet and dry extremes.
‘And there's evidence that these sorts of unusual jet stream undulations are increasing in frequency. In fact, they've doubled over the past 11 years compared to the previous 22 years. So that's a big concern. And we don't even know what's causing this jet stream behavior, but it makes sense that something to do with climate change might be involved. When you put the level of heat and moisture into the atmosphere that we've done over the past few decades, something has to give. Weather patterns have to shift. And one of the culprits we're looking at right now is the fact that the sea ice in the Arctic is about a factor of 2 less than it was 40 years ago, and that could be affecting global weather patterns and the jet stream.’
So here we have an eminent concerned meteorologist, and all he talks about is CO2 and reducing the burning of fossil fuels, while studiously ignoring the fact that those same jet streams are being systematically abused in a way never tried before. Also, incidentally ignoring the obvious fact that there is enough heat at the equator to melt all the sea ice (and doubtless much more) if the atmosphere is churned up enough.
