3. [Kutzbach 1970]
   Uses eigenvector analysis of Jan. and Jul. SLP maps from 1899 to 1969 to show geographic regions of greatest year-to-year variability. Pc's are used to identify times of change and different regimes. Tries to overcome studies of indices for large scale climate analysis. 1st eof of slp in Northern Hemisphere is similar to the AO pattern. Finds two moments of change: 1920 and 1950 (earlies). Out of phase pressure variations in northern oceans.

7. [Dyer 1975]
   Performs PCA of 157 stations with annual precipitation in South Africa. Subsequently, rotated PCA are applied to obtain more clear structures, which is the case. However, a cellular arrangement is not obtained as intended for prediction. A cluster/regionalization is attained by depicting for each station the PCA which correlates best to it. This leads to a grouping of stations into clear regions. Within each region the most important stations are retained through elimination of the less representative ones making again PCA within each region several times. The station which correlates best with the unimportant eofs are eliminated.
   PCA, rotated PCA, annual precipitation, cluster analysis, regionalization.

11. [van Loon and Williams 1976a]
    Nice historical introduction with references to previous attemps of studing climate change in temperatures.
    They relate temperature and circulation trends in winter. The size of trends in higher latitudes is determinant for hemispherical trends. The poleward transport of energy in times of warming is greater than in times of cooling and takes place in preferred longitude intervals on the front and rear sides of the Icelandic and Aleutian lows. If zonally averaged trends continue this increases temperature contrasts between polar and low altitudes. This should lead to increasing eddy intensity which should in turn cool the arctic.
    Interesante porque xa desvela relacion entre T e circulacion. Tamen polo gradiente latitudinal de T e o transporte de calor sensible polos eddies.
    NAO.

12. [van Loon and Williams 1976b]
    Different behavior in winter and summer (see for details). The sensible heat transport by atmospheric mean waves does not justify the temperature trends in summer.
    AO, summer trends.

13. [Madden 1976]
    Estimates natural variability for 74 grid point slp dataset. Estimates intrannual and interannual variability to asses signal to noise ratio and areas of potential predictability. Natural variability is determined as cliamtic noise. Relevant for dof area of research.
    Natural variability, predictability, dof.

15. [van Loon and Rogers 1978]
    Historical review on NAO. Defines NAO in terms of temperature seesaw with requirement that difference in temperature be above 4 K which characterizes a meridional oscillation in atmospheric mass with centers of action near the Icelantic Low and the Azores High.
    Describes pressure and temperature teleconection patterns. Spectrum analyses of temperature sites shows relationship with quasibienal osc. Suggests association between North Atlantic and North Pacific Oscillations. Long term regional trends linked to changes in the frequency of circulation types rather than variations in atmospheric constituents.

16. [Wade and Hewson 1979]
    Indices of deformation and compression of trees to exteme wind conditions. In areas were winds larger than 3 m/s, the deformation and compression indices of trees bear a linear relationship with annual wind speed. There were there are no meassurements this can be an indication of the extreme wind conditions. Exotic paper in itself. Funny side of the use of trees to infer climate conditions.
    Tree ring reconstructions, wind.
