Station charts
Rank 1,648 of 1,656 in Arizona, Oct 11. The 247 rank orders a state's stations by their 247 score out of 100: how reliably they report, how accurate their readings are against a reference station, how their readings pass their checks, and how they stand against the forecast.
247 score57.2of 100
Equal scores are ordered by the share of scheduled reports received, then the reports due in the week (the longer record first), then the median arrival, then the longest silence.
The score is the weighted mean of its six parts, from the last 7 days. How a station is ranked sets out each part.
The reports received are counted from the network's own archive of this station's reports. Its 247 rank is counted from Storm Station's own record, which holds less than 7 days of it so far: 370 of 1,974 scheduled reports received, 18.7%.
Against its reference: each temperature this station reports is compared with the nearest airport or climate reference station that reported within half an hour, up to 15 miles away. The figure is its reading less the reference's, on average, as both were reported; the typical difference is the root mean square. The difference in height is shown where both heights are known.

Station report
Drawn from its report of undefined, in the manner of the Field Book, and opened beside the plates that explain each part of it.
From the east southeast (103 degrees) at 1 mph, gusting 4 mph: force 1, a light air on the Beaufort scale.
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.
At 1,239 ft above sea level, 4 per cent of the atmosphere's air lies below the station. The standard atmosphere puts the pressure there at 28.61 inHg and the temperature at 54.6 F; the station's altimeter setting of 29.62 inHg means its barometer reads 28.32 inHg; it reports 74.0 F, 19.4 F warmer than standard.
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 1,239 ft up reads less: it weighs only the air above it.
On Oct 11 the noon sun stands 49 degrees above the horizon at 33.64 N, and the day is 11 h 21 min long. Level ground there takes 76 per cent of the noon sunlight a surface facing the sun would.
