The terms sensible heat and latent heat refer to energy transferred between a body and its surroundings, defined by the occurrence or non-occurrence of temperature change; they depend on the properties of the body. Sensible heat is sensed or felt in a process as a change in the body's temperature.
The sensible heat of a thermodynamic process may be calculated as the product of the body's mass (m) with its specific heat capacity (c) and the change in temperature (): =. Joule described sensible heat as the energy measured by a thermometer. Sensible heat and latent heat are not special forms of energy. Rather, they describe exchanges of ...
Heat transfer can either occur as sensible heat (differences in temperature without evapotranspiration) or latent heat (the energy required during a change of state, without a change in temperature). The Bowen ratio is generally used to calculate heat lost (or gained) in a substance; it is the ratio of energy fluxes from one state to another by ...
Contrast sensible heat. latent heat flux The movement of water vapor (a major transporter of latent heat) from one location to another, e.g. from the tropics toward the poles, where there is a persistent energy deficit relative to lower latitudes. Poleward latent heat flux reaches its global maximum of 1.5 × 10 15 watts at latitudes 38 °N and ...

After the experiments, Thompson was surprised to observe that a vacuum was a significantly poorer heat conductor than air "which of itself is reckoned among the worst", [55] but only a very small difference between common air and rarefied air. [56] He also noted the great difference between dry air and moist air, [57] and the great benefit this ...
People withered in blistering heat on both sides of the U.S.-Mexico border, where temperatures hit a scorching highs this week and many got little relief from the sun. Maribel Padilla, part of the ...
Ten cities in Mexico registered record-high temperatures in 10 cities, including the capital, authorities said on Friday, amid a searing heat wave that has prompted blackouts nationwide and pushed ...
