Encyclopedia > Temperature gradient

The temperature gradient in a given direction from a given spatial starting point is the rate at which temperature changes relative to distance in that direction from that point. Temperature is also the name of a song by Sean Paul. ...


The world temperature gradient is the rate at which temperature changes between the Earth's poles and the equator. In each hemisphere the temperature gradient from pole to equator is steeper in that hemisphere's winter than in its summer. Earth (often referred to as The Earth) is the third planet in the solar system in terms of distance from the Sun, and the fifth in order of size. ... The equator is an imaginary circle drawn around a planet (or other astronomical object) at a distance halfway between the poles. ... A sphere (< Greek σφαίρα) is a perfectly symmetrical geometrical object. ... Winter is one of the four seasons of temperate zones. ... For other senses of this word, see summer (disambiguation). ...


Temperature Gradient also refers to the difference in temperature caused by fluids working with or against gravity. Due to the temperature gradient, a nitrogen molecule at 300 K can only go 10km up (smaller molecules can go higher, so Hydrogen can go over 100 km up)

Temperature Patterns (367 words)
Temperatures on the Earth are largely dependent upon how much energy is received from the Sun, which varies both with latitude on the Earth and the time of year.
This latitudinal temperature gradient however, generates a global transfer of heat from equator to poles via the general circulation of winds, such that the equator is kept cooler and the poles warmer than they would be if the Earth had no atmosphere.
Differences between wintertime and summertime temperatures tend to be greatest in higher latitudes, and particularly in the interior of large landmasses such as North America and Asia far from the moderating influence of the oceans.
Temperature Gradient (104 words)
Temperature gradient is a very important in the snowpack because when temperature changes more than about 1 degree centigrade per 10 centimeters, the snow metamorphoses into weak, sugary, faceted crystals, which cause the lion’s share of avalanche accidents.
Large temperature gradients usually occur when cold, clear weather causes the snow surface to become very cold, or if the snow is especially shallow—or both.
(See faceted snow.) Luckily, temperature gradient metamorphism is completely reversible; when you take away the temperature gradient, the crystals start to metamorphose back into rounded, well-bonded grains.
