Station report
Adak NAS/Mitchell, in 6 sheets
Drawn from its report of Oct 15, 2026, 7:56 PM local time, in the manner of the Field Book, and opened beside the plates that explain each part of it.
2The air
Contents38.0 F with a dew point of 31.0 F, 76 per cent relative humidity. Air lifted from the station would cool to its dew point, where cloud forms, about 1,600 ft up.
From the Field Book
FB-WAT-002, Fig. CHumidity variablesThe same lift, worked for another air: how the humidity climbs as the air rises and cools.
FB-ENG-011, Fig. AWater vapour as a gasHow much vapour air can hold at each temperature, which sets the dew point.
FB-ENG-005, Fig. ALapse rates and stabilityThe dry rate the lifted air cools at, against the air around it.
3The wind
ContentsFrom the north northwest (340 degrees) at 5 mph: force 2, a light breeze on the Beaufort scale. The strongest gust today was 22 mph.
From the Field Book
FB-EVT-150, Fig. AHigh windHow a high wind reaches the ground, and the strengths a warning is issued at (40 mph sustained, 58 mph gusts).
FB-ENG-008, Fig. ACoriolis as geometryWhy large scale winds turn, and blow round a low rather than into it.
FB-INS-002, Fig. AASOSThe mast the wind is measured on, 33 ft above the ground.
4The column
ContentsAt 13 ft above sea level, 0 per cent of the atmosphere's air lies below the station. The standard atmosphere puts the pressure there at 29.91 inHg and the temperature at 59.0 F; the station's altimeter setting of 30.08 inHg means its barometer reads 30.07 inHg; it reports 38.0 F, 21.0 F colder than standard.
From the Field Book
FB-ENG-001, Fig. AAtmosphere in sectionThe whole standard atmosphere this station stands in, from the ground to the edge of space.
FB-ENG-003, Fig. CHydrostatic balanceWhy a barometer 13 ft up reads less: it weighs only the air above it.
5The sun
ContentsOn Oct 16 the noon sun stands 29 degrees above the horizon at 51.88 N, and the day is 10 h 25 min long. Level ground there takes 48 per cent of the noon sunlight a surface facing the sun would.
From the Field Book
FB-ENG-007, Fig. ARadiation budgetWhere the sunlight that reaches this ground goes once it arrives.
6The instrument
ContentsAn airport station, 13 ft above sea level. Its report of Oct 15, 2026, 7:56 PM local time is written on the sensors that made it.
From the Field Book
