The variability of atmospheric pressure and of air temperature are described, The diurnal variation of air temperature and the variation through the year respectively of monthly mean temperature, of the amplitude of the diurnal variation of temperature and of the possible number of hours of sunshine are analysed. The second chapter consists mostly of tables of observed values of air température, of the temperature, in the snow at depths of 30 and 60 centimetres and of atmospheric pressure.<br />Graphs on polar coordinates are used to represent and analyse the surface winds. Ceilings and visibilities are presented both in separate tables of frequencies of occurence and in a table of simultaneous frequencies of occurence.<br />Chapter III includes daily synoptic upper air charts for the 700 and 600 mb isobaric surfaces at 1500 G.M.T.. Isohypses are drawn for every 4 geopotential decametres and quoted in D Factors at 700 mb (cf.I.C.A.O. : doc 7200, page 41) and as the absolute topography<br />at 600 mb. Temperatures are in degrees Celsius and isotherms are drawn for every 5°C their curvature being used to indicate as far as possible warm and cold advection, frontal waves... etc.<br />Graphs of atmospheric pressure at a selection of stations in Greenland are included in an appendix.<br />It should be noted that the elevation of the Station has been taken as 2 993 m. throughout this volume,although 2970. 7m has recently been adopted for the new reference point of the Station.<p align="left" style="line-height: 100%; margin-bottom: 0cm"><strong><font size="2" style="font-size: 10pt"><font face="GlyphLessFont, serif">ZUSAMMENFASSUNG </font><font face="GlyphLessFont, serif">( Résumé en allemand )</font></font></strong></p><p align="left" style="line-height: 100%; margin-bottom: 0cm"><font face="GlyphLessFont, serif"><font size="2" style="font-size: 10pt">Jetzt haben wir den zweiten Band, über die Wetterbeobachtungen am Boden an der Station</font></font></p><p align="left" style="line-height: 100%; margin-bottom: 0cm"><font face="GlyphLessFont, serif"><font size="2" style="font-size: 10pt">Centrale in Grönland (International Index Nummer 04,160), die vom 21, Juni bis 15, August 1951</font></font></p><p align="left" style="line-height: 100%; margin-bottom: 0cm"><font face="GlyphLessFont, serif"><font size="2" style="font-size: 10pt">durchgeführt wurden, fertig.</font></font></p><p align="left" style="line-height: 100%; margin-bottom: 0cm"><font face="GlyphLessFont, serif"><font size="2" style="font-size: 10pt">Im ersten Teil zeigt der Verfasser, der Leiter des Wetterstation während des grössten Teils</font></font></p><p align="left" style="line-height: 100%; margin-bottom: 0cm"><font face="GlyphLessFont, serif"><font size="2" style="font-size: 10pt">der betrachten Zeit war, manche Betrachtungen über die Klimabedingungen der Station.
