Why was it cold in the UK, but not across the world?

January was quite cold in the United Kingdom. But in the world in January was warmer than usual. Why?
Provisional figures from the Meteorological Office of the United Kingdom planned to propose that in January was the eighth coldest in history, the worst record since 1987.
And yet, says the researcher meets Minister David Parker, many areas, including much of South America, Africa, Asia and Canada, had a enero warmer than usual.
Everything is a question of different models, the influence on climate. In the case of the United Kingdom, the culprit is the wind.
It just depends on how the wind blows, especially in the first half of the month, says Parker.
The wind from the north and northeast, has a cold zone, which covers Europe and much of Siberia, created in comparison to normal. Prevailing winds in the UK, are warmer in the winter in the south and southwest, and a change of direction is often to blame for bad winter. In 1963, the wind is almost always from the north, says Parker.
Dr. John Methven, University of Reading, Department of Meteorology said storms in the jet stream – the rapid movement of air in the atmosphere – are for a cold start in January guilt populated areas of the northern hemisphere.
There was a canal in western Europe, China and the east coast of North America.
The undulating jet stream in the north and south. [This year], the jet stream was further south than usual. We are in the polar air mass. This negative Arctic Oscillation is a short-term phenomenon, says Gavin Schmidt, a Scientists at the Goddard Institute for Space Studies. It can happen 10 days and then, but the current weather, which lasted from the United Kingdom in mid-December to mid January.
Heat, which is the rest of the world is less an effect in the short term. Weather experts are looking for temperature anomalies. For example, in January 2010 it was warmer than average in January between 1960-1990?
It was noted that 2009 was the second warmest ever globally and hottest ever recorded in the southern hemisphere. Overall, the average global temperature by 0.8 C (1.5F) increase since 1880 [according to NASA GISS], but the temperature anomalies for various regions and eras can be much larger, much hotter and colder.
It is conceivable, in January will be very hot, says Schmidt. The reason why the hot summer is mainly due to El Nino in the Pacific, moving about three or four months.
