  • The increased cloudiness and rainfall associated with La Niña periods typically reduces daytime temperatures and keeps nights warmer, particularly over northern and eastern Australia. (bom.gov.au)
  • In contrast, during El Niño events, reduced cloudiness means daytime temperatures are typically warmer than normal, exacerbating the effect of lower than normal rainfall by increasing evaporation. (bom.gov.au)

  • Empirical temperature scales are historically older, while theoretically based scales arose in the middle of the nineteenth century. (wikipedia.org)
  • Such scales are valid only within convenient ranges of temperature. (wikipedia.org)

  • As the global temperature shows the temperatures for Denmark shows a clear increase in the annual mean temperature in the last decades. (dmi.dk)
  • This increased exposure to sunlight could partially account for the increase in surface temperature that Mischenko and Hansen observed over the same time span. (nasa.gov)
  • F. Mean rate of increase of temperature with depth, and mean upward flow of heat. (scientificamerican.com)
  • Most materials expand with temperature increase, but some materials, such as water, contract with temperature increase over some specific range, and then they are hardly useful as thermometric materials. (wikipedia.org)
  • GHCN-M version 3 replaced version 2 in GISS temperature analysis because NOAA/NCDC no longer updates version 2. (columbia.edu)
  • 2. Temperature at which the liquid and vapour phase in a fluid inclusion homogenize to monophase liquid or vapour. (encyclopedia.com)
  • This gives an indication of the minimum trapping temperature of the fluid inclusion. (encyclopedia.com)

  • As detailed below, the real temperature of a surface can in some cases be calculated by dividing the brightness temperature by the emissivity of the surface. (wikipedia.org)
  • Ocean surface temperatures worldwide shot up by 5-8°C for a few thousand years - but in the Arctic, it heated up even more, to a balmy 23°C (73°F). This caused a severe dieoff of little ocean critters called foraminifera , and a drastic change of the dominant mammal species. (ucr.edu)
  • For instance in 170 AD, physician Claudius Galenus mixed equal portions of ice and boiling water to create a "neutral" temperature standard. (wikipedia.org)
  • The triple point is a singular state with its own unique and invariant temperature and pressure, along with, for a fixed mass of water in a vessel of fixed volume, an autonomically and stably self-determining partition into three mutually contacting phases, vapour, liquid, and solid, dynamically depending only on the total internal energy of the mass of water.
