  2. Lapse rate - Wikipedia

    en.wikipedia.org/wiki/Lapse_rate

    It varies with the temperature and pressure of the parcel and is often in the range 3.6 to 9.2 °C/km (2 to 5 °F/1000 ft), as obtained from the International Civil Aviation Organization (ICAO). The environmental lapse rate is the decrease in temperature of air with altitude for a specific time and place (see below). It can be highly variable ...

  3. Effects of high altitude on humans - Wikipedia

    en.wikipedia.org/wiki/Effects_of_high_altitude...

    Atmospheric pressure decreases following the Barometric formula with altitude while the O 2 fraction remains constant to about 100 km (62 mi), so pO 2 decreases with altitude as well. It is about half of its sea-level value at 5,000 m (16,000 ft), the altitude of the Everest Base Camp , and only a third at 8,848 m (29,029 ft), the summit of ...

  4. Human thermoregulation - Wikipedia

    en.wikipedia.org/wiki/Human_thermoregulation

    Simplified control circuit of human thermoregulation. [8]The core temperature of a human is regulated and stabilized primarily by the hypothalamus, a region of the brain linking the endocrine system to the nervous system, [9] and more specifically by the anterior hypothalamic nucleus and the adjacent preoptic area regions of the hypothalamus.

  5. Tropopause - Wikipedia

    en.wikipedia.org/wiki/Tropopause

    The tropopause is defined as the lowest level at which the lapse rate decreases to 2°C/km or less, provided that the average lapse-rate, between that level and all other higher levels within 2.0 km does not exceed 2°C/km. [1] The tropopause is a first-order discontinuity surface, in which temperature as a function of height varies ...

  6. Equivalent potential temperature - Wikipedia

    en.wikipedia.org/wiki/Equivalent_potential...

    So cool air lying on top of warm air can be stable, as long as the temperature decrease with height is less than the adiabatic lapse rate; the dynamically important quantity is not the temperature, but the potential temperature—the temperature the air would have if it were brought adiabatically to a reference pressure. The air around the ...

  7. Troposphere - Wikipedia

    en.wikipedia.org/wiki/Troposphere

    The gas layers of the troposphere are less dense at the geographic poles and denser at the equator, where the average height of the tropical troposphere is 13 km, approximately 7.0 km greater than the 6.0 km average height of the polar troposphere at the geographic poles; therefore, surplus heating and vertical expansion of the troposphere ...

    Quiet time allows us to make more eye contact with people and see other people, notice other people and potentially have more empathy for others.” 2. Relaxation reduces the need for health care ...

  9. Atmospheric temperature - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_temperature

    Average maximum yearly temperature is 28.7 °C and average minimum is 21.9 °C. The average temperature range is 5.7 °C only. Temperature variation throughout the year in Aracaju is very damped, with a standard deviation of 1.93 °C for the maximum temperature and 2.72 °C for the minimum temperature. [6]
