Sound Meteorological reasons for US temperature fluctuations as the globe cools overall
The last year the US has been warm and it can be directly traced to the changes taking place in the Pacific as the cooling PDO deepens, resulting in a fall in global temps, but rapid responses up and down across the US based on the water in the tropical Pacific. The theory is simple. The cooling of the Pacific tropical waters overall forces a global reaction that leads to the start of the cool down, that will be shown In a chart below, but the US temp response is inverse to the temps in the central Pacific relative to the temps In the eastern Pacific . The physical reaction will be discussed below, and it will be made clear as to why simply looking at what is going on over 10% of the globe is pure agenda driven drivel that the AGW crowd , pushed by many in government and science in this country, can be revealed as ignorance to basic sound logic, common sense, and science
The key is that no matter what the water temp, it has to be warmer in the central Pacific than eastern Pacific. If you have a warm event going on ( the el nino) then the core of the warmth must be in the in the central Pacific. If a cold event ( la nina) then the only way the US is cold is if the water is colder near South America. If the core of the cold is back west, then it creates a pressure and temperature pattern across the globe that will force it to be warm in the US . The same type of thing happened in the mild la nina winters of the MID 1970s, before the reversal in the late 70s, something I believe could happen this winter!
in a cold regime, lets look mid 09 to mid 10 its warmer in the center

so you understand the physical reasons, it has to do with the overall global temp and the results of warming and cooling of this area of immense energy on the global pattern. Warm the water in the central pac and you create lower than normal pressures in this area and there has to be compensating rises in pressure over N America. This is greatest in the winter season. Why? because in the tropical pacific seasonal temp variaions are much less than in the temperate regions, so a slight pressure fall here because of warming will demand a bigger response to the positive where its cold, again remember the lesson of the cold morning vs the hot afternoon and how easy it is to get temps to bounce up and down when its very cold ( takes very little energy change) as opposed to when its hot. The same change in energy for 1 degree at 80 will produce more than a 15 degree change around 0.
Now look at the Pacific while the US has been warm over the last year
