Abstract
A DISCUSSION by Dr. A. B. Rosenstein of the conditions of temperature in central and southern Spain is published in vol. xxxiv. (part iii., 1911) of Aus dem Archiv der deutschen Seewarte, based on observations of the last twenty years of the last century, and including a longer series for Lisbon, San Fernando, Coimbra, and Madrid. The last four stations represent essentially different climatological types as previously pointed out by Hellmann. The author deals with the observations in considerable detail (twenty-seven tables), but we can only very briefly refer here to one or two of the results. The amplitude of the daily range, being chiefly dependent upon the season, is smallest in winter (December) at the above-mentioned stations (at San Fernando in April), and greatest in summer (August); in the latter season the mean daily range at Madrid is 13'8° C., twice that at Lisbon and San Fernando. With reference to the yearly range, one of the tables shows the deviations of the monthly from the yearly means, the sum of the greatest plus or minus monthly departures being given as the expression of the mean yearly oscillation. The stations are divided into three groups: (1) coastal, where the aggregate mean yearly oscillation is between 11.5° and 15.3° C.; (2) more inland, oscillation between 15.9° and 18.2°; and (3) central tableland and plateaux, oscillation between 18.9° and 20.1°. This useful paper closes with tables showing the interdiurnal variability of temperature at Madrid (yearly mean 1.5° C.) and San Fernando (1.0°).
