The Australian and regional seasonal and
annual anomalies are calculated as arithmetic averages of their respective monthly average anomaly.
Pass over the data set and assemble average
annual anomalies in each cell of a 5 × 5 degree grid of latitude and longitude.
Your annual anomalies agree closely with mine, so we seem to be working from the same data and the difference seems to be one of methodology.
This is partly explained by using
annual anomalies in your analysis.
The respective mean

That gullibility probably has a lot to do with regional short - term temperature fluctuations, which are an order of magnitude larger than global average
annual anomalies.

annual anomalies (°C) in the region of Atlantic hurricane formation, relative to the 1961 to 1990 mean.
Also, for your discussions, you'll probably need to download the data and create comparative graphs between geographic areas and graphs of
annual anomalies.
Individual
annual anomalies have the disadvantage that they are of little statistical significance, and yet they are the stuff of headlines, as we have seen.
OK, I have to admit I've lost patience with the back and forth about
annual anomalies.
Nest surveys are positive (blue) and negative (red)
annual anomalies plotted against the survey year on the bottom x axis.
The annual anomaly is the average of two successive numbers in the sequence.
by the way, the largest
annual anomaly (negative) occurred 1979 - 1980 and took place in the SH, with -3 million square km lost compared to the NH loss of -2 million square km last year.
The positive slope of anomalys show that the rate of warming is accelerating, not that warming is occuring, warming is proven to be occuring by
all Annual anomalys simply being positive for the last twenty years.
Second, the chart uses
annual anomaly when monthly is available.
It is easy to see from
the annual anomaly values (not the five - year mean smooth line) that the record exhibits «regimes» of changing trends: -LSB-...] From about 1976 to about 1998 it is strongly positive.
My guess is that
the annual anomaly for 2016 will be 0.93 °C, 0.07 °C higher than 2015.
The annual anomaly of the global average surface temperature in 2014 (i.e. the average of the near - surface air temperature over land and the SST) was +0.27 °C above the 1981 - 2010 average (+0.63 °C above the 20th century average), and was the warmest since 1891.
My updated guess for the 2016
annual anomaly is now 0.96 °C, a big jump from 2015's 0.87 °C.
I created cumulative anomaly plot; adding
annual anomaly from 1981 to 2010, of both BEST and GHCN v2 and then looked at the difference.
When you say you «remove the average monthly anomalies» the only average monthly anomalies that make sense to me would those used to calculate
an annual anomaly.
To fill in these areas requires NOAA to reach out maybe 1250 km or more (in other words using Atlanta to estimate a monthly or
annual anomaly in Chicago).
One final point about this code: it performs a further step which isn't in the above description, computing a «smoothed» global
annual anomaly — a simple moving average over several consecutive years.
Using the linear regression line allows us to predict
an annual anomaly of 1.08 °C.
It could have a linear
annual anomaly trend.

Next week we'll be tackling the «
anomalies» in the
Annual Report: the notes section.
The team used these quality, adjusted daily series to calculate other series for
annual and seasonal
anomalies over the past century.
The
annual temperature
anomalies for 1997 and 1998 were 0.51 °C (0.92 °F) and 0.63 °C (1.13 °F), respectively, above the 20th century average, both well below the 2015 temperature departure.

First, a graph showing the
annual mean
anomalies from the CMIP3 models plotted against the surface temperature records from the HadCRUT4, NCDC and GISTEMP products (it really doesn't matter which).

Which of the various data sets of average

anomaly is closest to the truth?
An
annual value is available if there are 10 valid monthly temperature
anomaly values.
One finds on the secular time scale that both of the X - and Y - component temporal,

anomalies.
But here is the besetting
anomaly of the Turner prize: there is the work for which an artist is shortlisted, and then there is the work presented in the
