  2. Global surface temperature - Wikipedia

    en.wikipedia.org/wiki/Global_surface_temperature

    Projected global surface temperature changes relative to 1850–1900, based on CMIP6 multi-model mean changes. The IPCC Sixth Assessment Report defines global mean surface temperature (GMST) as the "estimated global average of near-surface air temperatures over land and sea ice, and sea surface temperature (SST) over ice-free ocean regions, with changes normally expressed as departures from a ...

  3. List of countries by average yearly temperature - Wikipedia

    en.wikipedia.org/wiki/List_of_countries_by...

    This is a list of countries and sovereign states by temperature. Average yearly temperature is calculated by averaging the minimum and maximum daily temperatures in the country, averaged for the years 1991 – 2020, from World Bank Group , derived from raw gridded climatologies from the Climatic Research Unit .

  4. List of cities by average temperature - Wikipedia

    en.wikipedia.org/wiki/List_of_cities_by_average...

    This is a list of cities by average temperature (monthly and yearly). The temperatures listed are averages of the daily highs and lows. Thus, the actual daytime temperature in a given month may be considerably higher than the temperature listed here, depending on how large the difference between daily highs and lows is.

  5. Atmospheric temperature - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_temperature

    Average yearly temperature is 22.4 °C, ranging from an average minimum of 12.2 °C to a maximum of 29.9 °C. The average temperature range is 11.4 °C. [6] Variability throughout the year is small (standard deviation of 2.31 °C for the maximum monthly average and 4.11 °C for the minimum). The graph also shows the typical phenomenon of ...

    The temperature on land rose by 1.59 °C while over the ocean it rose by 0.88 °C. [3] In 2020 the temperature was 1.2 °C above the pre-industrial era. [4] In September 2023 the temperature was 1.75 °C above pre-industrial level and during the entire year of 2023 is expected to be 1.4 °C above it. [5]

  7. Logarithmic mean temperature difference - Wikipedia

    en.wikipedia.org/wiki/Logarithmic_mean...

    In thermal engineering, the logarithmic mean temperature difference (LMTD) is used to determine the temperature driving force for heat transfer in flow systems, most notably in heat exchangers. The LMTD is a logarithmic average of the temperature difference between the hot and cold feeds at each end of the double pipe exchanger.

  8. 'Feels like' temperature: What does it really mean and how ...

    For example, in a scenario where the actual temperature is 10 degrees but the "feels like" temperature is -5 degrees, what that really means is that the wind chill is making it feel as if the air ...

  9. Template talk:Weather box - Wikipedia

    en.wikipedia.org/wiki/Template_talk:Weather_box

    The template has rows for "Mean maximum" and "Average high" temperatures, and similarly for "Mean minimum" and "Average low" temperatures. From context I gather that the "mean maximum" temperature is the mean maximum for the month (or year, in the "Year" column), whereas the "average high" is the mean maximum temperature for the day in that month (or full year, for the "Year" column).
