Dependence of Snowfall on Temperature
D'OOGE has reported1 a correlation between amount of snowfall in inches and temperature at the time of snowfall. His data showed that maximum depth of snowfall occurred at a daily mean temperature of − 11° C. ; Bossolasco2 correlated frequency of occurrence of snowfall with temperature and found maximum occurrence at approximately the same temperature. These observers assumed that the mean daily temperature recorded at the level of observation was a reasonable estimate of the temperature at the level of formation of the snow. From the data presented, conclusions were drawn concerning nucleation of snow crystals.
Sulla genesi delle precipitazioni
RiassuntoIn base a diverse serie di osservazioni meteorologiche raccolte su alte montagne, specie delle Alpi, l'A. dimostra che la conservazione della nebbia sottoraffreddata e la genesi delle precipitazioni nevose, sono regolate dalle temperature intorno a −11°, −4°–5° e −19° C, in completo accordo con lo spettro dei nuclei di congelamento dedotto sperimentalmente. Il risultato ha validità generale. — Segue l'illustrazione di talune deduzioni, con considerazioni interpretative.SummaryMaking use of different series of meterological observations carried out in high mountains, particularly in the Alps, the Author proves that the conservations-tendency of undercooled fog and the formation of snow are essentially controlled by the air-temperatures around −11°, −4°–5° and −19°C, in perfect agreement with the spectrum of freezing nuclei, known from laboratory work. The result is of general validity. — Some interpretations are presented.ZusammenfassungAuf Grund verschiedenen, im Hochgebirge, besonders in den Alpen, gesammelten meteorologischen Beobachtungsreihen, beweist der Verf., das die Erhaltungstendenz des unterkühlten Nebels und die Schneebildung wesentlich mitbestimmt werden durch die Luft-Temperaturen um −11°, −4°–5° und −19° C, in vollkommener Uebereinstimmung mit dem experimentell abgeleiten Spektrum der Gefrierkerne. Das Ergebnis hat allgemeine Gültigkeit. — Es folgen einige erläuternde Betrachtungen.
Gender Pay Gap in the European Union Labor Market
The participation of women in the European Union labor market has been increasing over recent years, putting an end to the notion that women are a marginal part of the labor force. However, such increased integration of women into paid work has neither ended the traditional gender divide between jobs nor it translated into gender equality in terms of economic opportunity and economic participation in the labor market. The purpose of the paper is to briefly discuss the gender pay gap in the EU labor market. The paper defines gender pay gap and provides a brief theoretical overview of the underlying causes of such pay asymmetry between men and women. Statistics provided for EU 25 reveal that the current policy attempts to reduce such a gender asymmetry still lack improvement in practice. The paper concludes with selected policy suggestions aiming to make a progress in the issue of the gender equality in pay.
