  2. Precipitation - Wikipedia

    en.wikipedia.org/wiki/Precipitation

    The standard way of measuring rainfall or snowfall is the standard rain gauge, which can be found in 10 cm (3.9 in) plastic and 20 cm (7.9 in) metal varieties. [83] The inner cylinder is filled by 2.5 cm (0.98 in) of rain, with overflow flowing into the outer cylinder.

  3. SevenMeters - Wikipedia

    en.wikipedia.org/wiki/SevenMeters

    The name SevenMeters derived from the realization that the water level will rise 7 meters if the global warming will melt all the ice in Greenland. In order to show what impact the possible climate change can have to the world, the SevenMeters group established 24 kilometers of red blinking LED-lights at 7 meters height during the UN's climate ...

  4. Height above mean sea level - Wikipedia

    en.wikipedia.org/wiki/Height_above_mean_sea_level

    Height above mean sea level is a measure of a location's vertical distance (height, elevation or altitude) in reference to a vertical datum based on a historic mean sea level.

  5. Flight level - Wikipedia

    en.wikipedia.org/wiki/Flight_level

    Flight levels [3] are described by a number, which is the nominal altitude, or pressure altitude, in hundreds of feet, and a multiple of 500 ft. Therefore, a pressure altitude of 32,000 ft (9,800 m) is referred to as "flight level 320". In metre altitudes the format is Flight Level xx000 metres.

    The monthly 24-hour average temperature ranges from −5.7 °C (21.7 °F) in January to 11.6 °C (52.9 °F) in July, and the annual mean is 3.07 °C (37.5 °F). Precipitation is common year-round (occurring on more than 250 days), but due to the influence of the monsoon , rainfall is especially heavy in summer, and more than 70% of the annual ...
