Quoting: One persistent abuser
of this technique is Pat Michaels, and in a recent piece he was unable to resist claiming that the century - scale trends (~ 0.8 C from 1891 - 1900 to 1991 - 2000 in the
annual mean) seen in this extended Southern Greenland
data apparently invalidate the notion
of polar amplification as predicted by the «models».
This can be done a number
of ways, firstly, plotting the observational

of 1980 - 1999 temperatures (as done in the 2007 report)(Note that the model output is for the
annual mean, monthly variance would be larger):

An analysis
of data pertaining to the period 1861 — 1986 reveals that (1) a 1 °C rise in the
mean annual air temperature
of the British Isles has historically been associated with a 35 % drop in the percentage
of days that the United Kingdom has experienced cyclonic flow, and (2) a 2 °C increase in the
mean annual air temperature over the sea to the north has typically been matched by a 60 % drop in the percentage
of days that the isles have experienced cyclonic flow originating from that source region.
Here we construct a database

-- 1.87 is the clear - sky, or the all - sky
annual mean infrared optical thickness; — if clear - sky, how the cloudless cases were selected out from the radiosonde
data set; — if it is the clear + cloudy (all - sky), how did he get it as global average value, when the cloud infrared optical depth is infinite (in half
of the cases); — if 1.87 is for all - sky, how much is the clear - sky value (if he got it).

Analyses
of tide gauge and altimetry
data by Vinogradov and Ponte (2011), which indicated the presence
of considerably small spatial scale variability in
annual mean sea level over many coastal regions, are an important factor for understanding the uncertainties in regional sea - level simulations and projections at sub-decadal time scales in coarse - resolution climate models that are also discussed in Chapter 13.
An «estimate» and / or «reconstruction»
of an
annual or decadal temperature

Our results agree with recent studies that
annual mean data - constraints from present day climate prove to not rule out climate sensitivities above the widely assumed sensitivity range
of 1.5 — 4.5 °C (Houghton et al. 2001).
Simulations where the magnitude
of solar irradiance changes is increased yield a mismatch between model results and CO2
data, providing evidence for modest changes in solar irradiance and global

annual mean temperature to solar forcing.
All
of these characteristics (except for the ocean temperature) have been used in SAR and TAR IPCC (Houghton et al. 1996; 2001) reports for model -

annual means of the following climate characteristics which encompass corresponding empirical estimates: global SAT 13.1 — 14.1 °C (Jones et al. 1999); area
of sea ice in the Northern Hemisphere 6 — 14 mil km2 and in the Southern Hemisphere 6 — 18 mil km2 (Cavalieri et al. 2003); total precipitation rate 2.45 — 3.05 mm / day (Legates 1995); maximum Atlantic northward heat transport 0.5 — 1.5 PW (Ganachaud and Wunsch 2003); maximum

On blogs like Dr. Curry's I continually see learned, and heated, arguments over the
meaning of fluctuations in the «

However, the National Assessment Synthesis Team, co-chaired by Thomas Karl, Director
of the National Climatic
Data Center, took the result so seriously that they commissioned an independent replication
of this test, only more inclusive, using 1 - year, 5 - year, 10 - year and 25 - year running
means of the U.S.
annual temperature.
For example, the HadCRUT3, GISS, etc.
data sets
of annual mean global temperature each report global temperature changes as differences from a 30 - year average.
HadCRUT3, GISS, etc.
data sets report

The wide range
of studies conducted with the ISCCP datasets and the changing environment for accessing datasets over the Internet suggested the need for the Web site to provide: 1) a larger variety
of information about the project and its
data products for a much wider variety
of users [e.g., people who may not use a particular ISCCP
data product but could use some ancillary information (such as the map grid definition, topography, snow and ice cover)-RSB-; 2) more information about the main
data products in several different forms (e.g., illustrations
of the cloud analysis method) and more flexible access to the full documentation; 3) access to more
data summaries and diagnostic statistics to illustrate research possibilities for students, for classroom use by educators, or for users with «simple» climatology questions (e.g.,
annual and seasonal
means); and 4) direct access to the complete
data products (e.g., the whole monthly
mean cloud dataset is now available online).

Correlation (color) and regression maps (contour)
of SST (left) and SLP (right) associated with the first EOF modes
of annual precipitation (a, b), low - frequency precipitation (c, d), and total water storage (e, f), which are calculated using

of annual precipitation, 10 - year running
mean for precipitation, and 10 - year running
mean leading with 5 - year for total water storage.
Correlation coefficients are calculated using
annual mean data for the first EOF mode

Presumably if we did a 40 year smoothing on the temperature record
of the last 100 years it would show a lot less variation than when we show the
data in an
annual form — but would it
mean missing out a lot
of the useful information and giving a misleading impression?
We blended surface meteorological observations, remotely sensed (TRMM and NDVI)
data, physiographic indices, and regression techniques to produce gridded maps
of annual mean precipitation and temperature, as well as parameters for site - specific, daily weather generation for any location in Yemen.
Firstly, we tested the hypothesis that there should be a positive relationship between

data spanning 1876 — 2009.
Weak negative correlations were found between the
mean annual NCEP RH and cirrus over oceans, but again, most
of the
data over oceans are in the air traffic corridors where contrail formation and raw aircraft emissions could affect the cirrus trends more than over land because
of greater susceptibility in the more pristine marine air.
«The total

of 1.2 or 1.5 × 1015 kg depending on whether surface pressure or water vapor
data are used; somewhat smaller than the previous estimate.
«Much
of the work has focused on evaluating the models» ability to simulate the

of the climate system.
Dr Curry, I think the four types
of constraints I found in the
annual global
