Sentences with phrase «varied as a function of temperature»

Higher metabolic and survival costs induced by predation risk were only partially offset by changes in consumption rates and assimilation efficiencies and the magnitude of non-consumptive effects varied as a function of temperature.

You have correctly noted that the absolute surface temperature varies enormously on very short distances as a function of the terrain (something that is true for rural as well as urban environments).

Functions such as hormonal secretions, heart rate, body temperature and feelings of sleepiness and alertness vary regularly with peaks and troughs across the day.

The exact way that intensities and fluxes vary as a function of CSD depends on the spatial temperature distribution as well as the Planck function, or in combination, it depends on the spatial distribution of the Planck function (for local temperature).

Trends as a function of CSD, Saturation: If the temperature varies monotonically over the distance from which most of the radiation reaching that level is emitted, then increasing the CSD will bring the upward and downward fluxes and intensities (at a given angle) toward the same value, reducing the net intensities and fluxes, until eventually they approach zero (or a nonzero saturation value at TOA).

Including emission along a path (Schwarzchild's equation), a flux will approach saturation as the optical thickness becomes large over scales where the temperature variation is small; at smaller optical thicknesses, the temperature distribution may vary and larger temperature variations make the nonlinearity of the Planck function important, but over short distances, the temperature variation can be approximated as linear and the associated Planck function values can be approximated as linearly proportional to distance for small temperature changes, so the flux will approach an asymptotic value as a hyperbolic function (the difference between the flux and the saturation value of the flux will be proportional to 1 / optical thickness per unit distance (assuming isotropic optical properties (or even somewhat anisotropic properties), it will have that proportionality for all directions and thus for the whole flux across an area).

Thus there is convection within the troposphere that (to a first approximation) tends to sustain some lapse rate profile within the layer — that itself can vary as a function of climate (and height, location, time), but given any relative temperature distribution within the layer (including horizontal and temporal variations and relationship to variable CSD contributors (water vapor, clouds)-RRB-, the temperature of the whole layer must shift to balance radiative fluxes into and out of the layer (in the global time averae, and in the approximation of zero global time average convection above the troposphere), producing a PRt2 (in the global time average) equal to RFt2.

Water Use per Acre of Almonds: All crops require water and the total water requirement varies throughout the growing season as a function of temperature and other climatic factors, the characteristics of the plants themselves, soil conditions, irrigation methods and efficiencies, and more.

Because IR in these wavelengths is not efficiently intercepted by greenhouse gases, its intensity varies mainly as a function of surface temperature, according to the Stefan - Boltzmann law.

It is however, not considered as a climate «forcing» because the amount of H2O in the air varies basically as a function of temperature.»

Soil temperature varies from month to month as a function of incident solar radiation, rainfall, seasonal swings in overlying air temperature, local vegetation cover, type of soil, and depth in the earth.

If I was really obsessive about this I could mount the IR thermometer on a jig where I could precisely vary the angle and measure the temperature as a function of angle.
