US Anomaly: Sep 25th, 2010

The last two weeks have been very similar.  Slightly warmer than average in the south and central portions of the country with slightly cooler than average temperatures in the northern part of the country. This week is just warmer than the week before.  As I have previously stated, as the fall progresses so will the amount of variation from the average.  This week this starts to show as significantly warmer weather developed from Ohio and south.

The cooler than average temperatures in the western part of the country that have been yearly trend are in for a huge reversal next week though as news of record breaking temperatures has been making the rounds.  This is going to get worse as a very strong La Nina is cooling the ocean off the coast of California down.  This causes warmer and drier weather from California and the regions east of it.  So the colder ocean is going to cause hot dry weather in southern US this winter, but will also cause cold wet weather in the northern parts of the country.  All of which is related to natural cycles of the ocean.  This will be an interesting fall.

Much like last week showed, 2009 was the opposite of 2010 for where the country was warm and where it was cool.  2007 was interesting as it showed some much cooler weather in the western states.

Be ready for big changes next week in the anomaly maps next week.  It will be interesting to see how the current warm AMO and the strong La Nina impact the fall and the winter across the country.

    Look at the fundamental assumption that the NCDC/NOAA has made here: The last thirty years of the last century is “normal.” I suppose that is defensible — the period is long enough to cover most of the short term cycles. But, there are plenty of longer-term cycles.

    But there is the second, implied assumption: All change is bad. If it wasn’t that way when you were born, then it’s wrong.

    The AMO is a good example of a long term cycle that has significant impact on the Earth’s annual temperature, but it has only been defined for 10 years.

    There is simply no information on the scale of the AMO. Every El Nino is different in strength and duration. If the AMO behaves in the same manner then we don’t know enough to predict anything.

    At best if the AMO is removed there has been 0.3C warming in the past 100 years. Our information is very limited. The claims about CO2 are absurd.

    I will have it looked at. Thanks for the info.
