摘要:

AbstractOn the basis of the CLE. (1931) colour metric an expression is developed for the colour co‐ordinates and luminosity of a given light source seen at night through an atmosphere of known optical properties. This is applied to an observation on a mercury vapour lamp in a highly selective haze of the type sometimes called “blue f

摘要:

AbstractA detailed analysis of the rainfall of Adelaide, South Australia, has shown that throughout the 95 years 1839‐1933 there has been a definite oscillation, with a period and amplitude of approximately 23 years and 30 days respectively in the incidence and duration of the winter rains. The amplitude, though small, is nevertheless about 20 per cent of the length of the rainfall season. The total quantity precipitated has shown no statistically significant change

摘要:

AbstractThe cold Benguela current flowing northward along the West Coast of South Africa tends to keep the temperatures along the seaboard low and uniform. On the other hand, under eertain pressure distributions hot dry fdhnlike winds, coming down from the interior 3,000ft.‐plateau, and known as berg winds, cause remarkably high temperatures along the coast on the days when they occur. These berg winds are mostly in evidence during the months April to August, their frequency during this period being about eight days per month.An analysis of extreme temperatures registered at Port Nolloth shows how these hot winds cause a remarkable asymmetry in the frequency distribution of maximum temperatures and to a much lesser degree in that of the minimum temperatures.There is a very close correlation between the number of berg wind days per month and the mean monthly maximum temperatures along the West Coast, showing that the mean monthly temperatures along the West Coast are markedly influenced by these berg winds.By disregarding the extreme temperatures registered during berg wind days it is shown that the asymmetry in the temperature frequency distribution curves disappears almost entirely, and by only using the extremes of other days than berg wind days it is further shown what the seasonal variation of mean monthly temperatures would likely be if the Benguela current reigned suprem

摘要:

AbstractThe lunar atmospheric tide a t Melbourne, Australia, has been determined from nearly 36 years' record; the mean result is 28 sin (2t +84.0°) microbars, with a probable error of 2.3 microbars. This is compared with the determination made by Neumayer from data for the years 1858‐63: his result is found to be affected by so large a probable error as to be practically without value.The Melbourne tide is affected by a seasonal variation, of normal type as regards phase (high tide occurring later in December than in June), but abnormal in that the amplitude is greatest in December.The solar daily variation a t Melbourne is also analysed, as determined from all or almost all days, and separately from 421 days of barometric disturbance; the latter show the expected “concave variation,” the complement of Bartels' “convex variation” characteristic of barometrically
