Related to effective temperature: effective temperature index

ef·fec·tive tem·per·a·ture in·dex

a composite index of environmental comfort which is compared after exposure to different combinations of air temperature, humidity, and movement.

ef·fec·tive tem·per·a·ture

(e-fek'tiv tem'pĕr-ă-chŭr)
A comfort index or scale that takes into account the temperature of air, its moisture content, and movement.


exerting a measurable effect.

effective circulating volume
that part of the blood volume that is effectively perfusing the tissues at a particular time.
effective focus
see effective focal spot.
effective refractory period
time interval during which the effector cell remains unresponsive after a previous reaction to a stimulus: see also refractory period.
effective temperature
an expression of the temperature combined with humidity and wind speed.


the degree of sensible heat or cold, expressed in terms of a specific scale. See also hypothermia, hyperthermia.

absolute temperature
that reckoned from absolute zero (−459.67°F or −273.15°C).
air temperature
the temperature of the surrounding air as measured by a dry-bulb thermometer.
ambient temperature
temperature of the immediate environment.
body temperature
a prime technique for assessing health status of a patient. Always a rectal temperature. Average temperatures above which hyperthermia, pyrexia or fever can be said to occur are listed under pyrexia.
critical temperature
1. that below which a gas may be converted to a liquid by pressure.
2. the environmental temperature at which the body is unable to maintain a constant body temperature and at which heat production must be increased (cold temperatures) or at which heat loss must be increased (high temperatures).
effective temperature
the combination of air temperature, humidity and wind speed. See also temperateness index.
environmental temperature
air temperature.
nonpermissive temperature
one at which a conditional gene mutation is nonfunctional. See also temperature-sensitive mutation.
normal body temperature
that usually registered by a healthy animal. See pyrexia.
permissive temperature
one at which a conditional gene mutation can express its normal function. See also temperature-sensitive mutation.
premortal temperature fall
the sudden fall in body temperature of a previously fevered animal just before death.
rectal temperature
the body temperature as measured by a rectal thermometer which has been in situ and in contact with the mucosa of the rectum with the anal sphincter tightly closed for at least 30 seconds. Alternative equipment is a dipolar electrode in a rectal probe.
temperature stress
exposure to excessively high or low environmental temperature.
windchill temperature
a combination of wind velocity and air temperature. See also effective temperature (above).

From the relationship between a star's effective temperature and its apparent colour shown in Figure 7, we can construct a representation of the relative appearance of CQ Boo at the extremes of its size and temperature during one pulsation cycle (ignoring the effect of limb-darkening) (Figure 18).
Using the Peltier effect of ThermoElectric Cooling(TEC), AMBI(TM) works like an electronic ice cube: just flip the switch and the same technology used by NASA to chill the shell of the space shuttle and in some portable refrigerators and camping coolers chills the cool plate to a comfortable, yet effective temperature.
