Had it happened to someone else I might suggest a chance electrical anomaly and the law of large numbers as an explanation — with billions of people having billions of experiences every day, there's bound to be a handful of extremely unlikely events that stand out in their timing and meaning.

Most previous Antarctic ice core records have not included many of the elements and chemical species that we study, such as heavy metals and rare earth elements, that characterize the anomaly — so in many ways these other studies were blind to the Mt. Takahe event.»

Moreover, one of the findings of the research that identified the COMMD1 gene virtually eliminated genetic recombination (a cross-over event) as the cause of these anomalies, the obvious conclusion being that neither test was 100 % accurate and that a second gene was involved.

Doesn't using a «baseline for anomaly calculation» «equal to the time span being analyzed» decrease REAL extreme weather event probabilities much the same way as using a sliding baseline minimizes the slope of temperature increase?

In other words, you are picking on «high amplitude and persistent ridging» as the red herring (short term events) to distract from the probability analysis (regarding the long term anomaly trend attributable to increased RF).

I would be more than happy to see a tidal chart showing an estreme anomaly in sea level at thesame moment as with observed tidal ice events, but the charts I've seen show 100 cm tides even at the full moon.

Both also describe an outstanding event in the late 1960s early 1970s where a region of very low salinity was observed (known as «the Great Salinity Anomaly» — GSA).

The additional noise can be seen in the failure of global temperature anomalies to respond as one would expect to the lesser El Niño events of 2002/03, 2004/05, and 2006/07.

NINO3.4 SST anomalies are a commonly used proxy for the strength and frequency of El Niño and La Niña events, also known as ENSO.

Third, note how the sea surface temperature anomalies in the Western Pacific (and East Indian Ocean) continue to rise as the La Niña event strengthens.

Apparently you are having trouble understanding that this graph shows the monthly anomalies for a period that encompassed the 2015 - ’16 El Nino warming event and its denouement only, and it was used to demonstrate the speciousness of attributing cherry - picked warming anomalies to humans, and dismissing cherry - picked cooling anomalies as «natural variability.»

Though a physical mechanism for this teleconnection has been suggested (18), relevant climatic signals of the North Atlantic events in Asia (such as temperature and moisture anomalies) are very small (19) indicating that internal feedbacks in monsoon dynamics may have amplified the weak external forcing.

The NINO3.4 index is defined as the average of sea surface temperature (SST) anomalies over the region 5 ° N - 5 ° S and 170 ° -120 ° W. El Niño (a warm event) is considered to occur when the NINO3.4 index persistently exceeds +0.8 °C.

These authors may have used a technique that effectively removed linear long term trend in temperature from their data but they did show that short term (sub-decadal) fluctuations in temperature (as measured by the temperature anomaly) are mainly due to ENSO events.

Keep in mind, when climate studies such as Thompson et al (2009) and Trenberth et al (2002) attempt to account for El Niño and La Niña events in the global surface temperature record they scale an ENSO proxy, like NINO3.4 SST anomalies, and subtract it from the Global dataset, removing the major wiggles.

It is instructive to compare these numbers with those characteristic of a set of the years during 1979 — 2012 with no or only one major regional extreme event (in terms of land surface temperature and land precipitation anomalies) in the NH midlatitudes, from late April / early May to late September / early October, as reported yearly since 1993 in the World Meteorological Organization statements on the status of the global climate (see also ref.

Figure 2.2 shows the patterns of tropospheric temperature anomalies over the Western Hemisphere, as sensed by the MSU, during the northern winters (December through February) of 1982 — 83 and 1997 — 98, which both correspond to strong El Niño events in the tropical Pacific, and during the winter of 1988 — 89, which corresponds to a La Niña event.

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.
