A generalized view of the heat index showing how the perception of heat by the human body increases with temperature but more rapidly at higher humidity levels. The heat index of a given combination of temperature and humidity is defined as the dry-bulb temperature which would feel the same if the water vapor pressure were 1.6 kPa. Quoting ...
In the sun, in the shade, on a rock, in a glade. For every different way there is to experience heat — in the sun, in the shade, on a rock, in a glade — there is a scientific debate about how ...
As a two-part measurement, heat index can be measured using charts or online calculators to explore the difference between the two figures and the amount of danger that heat index represents. A ...
The heat index and humidex measure the effect of humidity on the perception of temperatures above +27 °C (81 °F). In humid conditions, the air feels much hotter, because less perspiration evaporates from the skin.

The wet-bulb globe temperature (WBGT) is a measure of environmental heat as it affects humans. Unlike a simple temperature measurement, WBGT accounts for all four major environmental heat factors: air temperature, humidity, radiant heat (from sunlight or sources such as furnaces), and air movement (wind or ventilation).

The heat index explains why humidity makes a difference. Have you ever checked the temperature and noticed that it "feels" several degrees hotter? The heat index explains why humidity makes a ...
In thermal physics and thermodynamics, the heat capacity ratio, also known as the adiabatic index, the ratio of specific heats, or Laplace's coefficient, is the ratio of the heat capacity at constant pressure (C P) to heat capacity at constant volume (C V).
