We have just faced a year of freak weather conditions around the country with winter tornadic activity in the Deep South, floods in the Pacific Northwest and a number of
other weather anomalies that took down power lines, leaving home security systems futile.

Regarding the divergence problem for tree rings, is that an isolated incident or are there
other climate or
weather «
anomalies» like that from the early 1960's?
All projections I've seen (e.g., UW CIG) indicate this region will remain pleasantly habitable for people for longer than
other areas (think Texas, Oklahoma, Arizona) under the pressure of increasing numbers and extremes of
weather «
anomalies.»
Other types of natural
anomalies include solar variability and
weather patterns such as the El Niño southern oscillation.
Based on extensive Siberian snow cover during the fall, the researchers correctly forecasted cold
weather for much of the U.S., while most
other forecasters predicted warm
weather for the U.S.. For a comparison between predicted and observed temperature
anomalies, please see the following images: forecast temperature
anomaly Jan - Feb - Mar 2013 and observed temperature
anomaly Jan - Feb - Mar 2013, U.S. only.
In climate science, 30 years is the accepted trend period, partly I think for historical reasons, but the length of time also makes allowance for
anomalies arising from short - term fluctuations in
weather and
other events such as volcanoes.
Suppose «climate» is defined as the time and space scale (L) at which local «
weather»
anomalies (noisy departures from the expected climatic mean) sum up to cancel each
other out, thus yielding unambiguous deterministic responses to various external forcings.
Maybe this is OT, but I was wondering, along with the divergence problem for some tree rings, if there were
other «
anomalies» like it in climate or
weather in the early»60s.
A good question is why, likely because there is a warming accross the equator, not only at the equatorial Pacific, there is a drought in the Amazon,
other equatorial regions may also have temperature or
weather anomalies, I have not heard of them though.
The monthly average image is more accurate than the daily images because
weather anomalies and
other errors are less likely to affect it.
NOAA switched to a 1971 - 2000 baseline for their
anomaly calculations, for example — and there are really only two explanations — one is to artificially reduce the reported warming trend, and the
other is to provide a safer baseline for the
weather risk insurance industry.
