  2. Humidity - Wikipedia

    en.wikipedia.org/wiki/Humidity

    It does not take temperature into consideration. Absolute humidity in the atmosphere ranges from near zero to roughly 30 g (1.1 oz) per cubic metre when the air is saturated at 30 °C (86 °F). [8] [9] Air is a gas, and its volume varies with pressure and temperature, per Boyles law. Absolute humidity is defined as water mass per volume of air ...

    Maps using isotherms show temperature gradients, [2] which can help locate weather fronts. Isotach maps, analyzing lines of equal wind speed, [3] on a constant pressure surface of 300 or 250 hPa show where the jet stream is located. Use of constant pressure charts at the 700 and 500 hPa level can indicate tropical cyclone motion.

  5. Climate of Phoenix - Wikipedia

    en.wikipedia.org/wiki/Climate_of_Phoenix

    [citation needed] When active, the monsoon raises humidity levels and can cause heavy localized precipitation, flash floods, hail, destructive winds, and dust storms [17] —which can rise to the level of a haboob in some years. [18] August is the wettest month (0.93 in (24 mm)), while June is the driest (0.02 in (0.51 mm)).

  6. Atmospheric temperature - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_temperature

    The temperature of the air near the surface of the Earth is measured at meteorological observatories and weather stations, usually using thermometers placed in a shelter such as a Stevenson screen—a standardized, well-ventilated, white-painted instrument shelter. The thermometers should be positioned 1.25–2 m above the ground.

  8. Dew point depression - Wikipedia

    en.wikipedia.org/wiki/Dew_point_depression

    For a constant temperature, the smaller the difference, the more moisture there is, and the higher the relative humidity. In the lower troposphere, more moisture (small dew point depression) results in lower cloud bases and lifted condensation levels (LCL). LCL height is an important factor modulating severe thunderstorms.

  9. Humid continental climate - Wikipedia

    en.wikipedia.org/wiki/Humid_continental_climate

    The snowy city of Sapporo, Japan, has a humid continental climate (Köppen Dfa).. Using the Köppen climate classification, a climate is classified as humid continental when the temperature of the coldest month is below 0 °C [32.0 °F] or −3 °C [26.6 °F] and there must be at least four months whose mean temperatures are at or above 10 °C (50 °F).
