The climate is healthy; owing to the elevated situation it is somewhat cold, and is liable to sudden diurnal and seasonal changes; the temperature in January sometimes falls to 4° F.
I knew the props were still stored in the same place where I store my seasonal things.
There are brisk diurnal sea-breezes, and seasonal trades and counter-trades.
But the local variations thus indicated are brought out more fully by a consideration of seasonal, and especially winter, temperatures.
The cotton plant requires certain conditions for its successful cultivation; but, given these, it is very little affected by seasonal vicissitudes.
There is hardly any seasonal change to be observed, and the dampness of the climate causes the heat to be more oppressive than are higher temperatures in drier climates.
The determination of stellar parallaxes is a matter of great difficulty on account of the minuteness of the angle to be measured, for in no case does the parallax amount to I"; moreover, there is always an added difficulty in determining an annual change of position, for seasonal instrumental changes are liable to give rise to a spurious effect which will also have an annual period.
Between many of the countries there is a good deal of migration which is only seasonal or temporary, according to the demand for labour.
The normal seasonal march of pressure-change produces a maximum gradient in December and January, and a minimum gradient in April; but for every month in the year the mean gradient is for winds from southerly and westerly quarters.
"It's a seasonal place, according to Martha's description," I answered.
At Karasjok and Kremsmunster the seasonal variation in a i seems comparatively small, but at Potsdam and the Bureau Central it is as large as at Kew.
The net effect of the surrounding land is, in fact, to reverse the seasonal variations of the planetary circulation, but without destroying its type.
The seasonal variations have been well marked and extremely regular in Bombay.
A raucaria Bidwillii, the occurrence of small foliage-leaves, which have functioned as bud-scales, at intervals on the shoots affords a measure of seasonal growth.
There is also a great seasonal change in appearance and colour in this squirrel, owing to the ears losing their tufts of hair and to the bleaching of the tail.
Caniceps, but goes through no seasonal change of colour.
The phenomenon of seasonal dimorphism is of especial moment for the plankton dwellers.
The seasonal bending of the isotherms is, however, unsymmetrical for several reasons.
Rambaut's results were obtained with similar instruments similarly located, but he did not investigate the seasonal variations of diffusivity, or the effect of percolation.
Baldwin Latham made an elaborate examination of the meteorological conditions, and more particularly of the vapour tension, from which he draws the conclusion that the seasonal variations are due to exhalation from the ground.
4 At Fort Yukon five years' records showed mean seasonal temperatures of 14°, 60°, 17°, and -23.8° F.
It is decidedly less at Perpignan and Lisbon than at Potsdam, Kew and Greenwich, but nowhere is the seasonal difference more conspicuous than at Tokyo, which is south of Lisbon.
The values of a 2 at the various stations differ comparatively little, and show but little seasonal change.
Equally disastrous are those climatic or seasonal changes which involve temperatures in themselves not excessive but in wrong sequence; how many more useful plants could be grown in the open in the United Kingdom if the deceptively mild springs were not so often followed by frosts in May and June!
So far only the North Atlantic has been at all well studied and evidence of seasonal and periodic variations extending over a number of years has been obtained in this area.
As a result of its relatively great depth there are seldom any great fluctuations of level in this lake due to wind disturbance, but the lake follows the general rule of the Great Lakes (q.v.) of seasonal and annual variation.
Benjamin Franklin in 1775 and Charles Blagden in 1781, by means of numerous observations of temperature made on board the packets plying on the Atlantic passage, determined the boundaries of these two currents and their seasonal variations with considerable precision.
The surface currents of the Pacific have not been studied in the same detail as those of the Atlantic, and their seasonal variations Circulation are little known except in the monsoon regions.
Next, dependent on the inclination of the earths axis, is the division of the planetary year into the terrestrial seasons, with winter and summer changes of temperature, wind-strength and precipitation: these seasonal changes are not of the restrained measure that is characteristic of the oceanic southern temperate zone, but of the exaggerated measure appropriate to the continental interruptions of ~the northern land-and-water zone, to which the term temperate is so generally inapplicable.
In virtue of these physical characteristics, the air over the land becomes much warmer in summer and much colder in winter than the air over the oceans in corresponding latitudes; hence the seasonal changes of temperature in the central United States are strong; the high temperatures appropriate to the torrid zone advance northward to middle latitudes in summer, and the low temperatures appropriate to the Arctic regions descend almost to middle latitudes in winter.
In addition to these periodical fluctuations, there are also seasonal oscillations, the level being lowest in January and highest in the summer.
Parthenogenesis is prevalent in the Branchiopoda and Ostracoda, often in more or less definite seasonal alternation with sexual reproduction.
He considers the outbreaks are favoured by the seasonal heat and moisture of the spring and early summer, and the movement from place to place of infected rats or persons.
