Station report

Naval Station Roosevelt Roads, in 6 sheets

Drawn from its report of Oct 16, 2026, 1:04 AM local time, in the manner of the Field Book, and opened beside the plates that explain each part of it.

1The sky

Contents

A few clouds at 2,100 ft, broken at 4,600 ft, overcast at 6,500 ft; the ceiling is 4,600 ft; visibility 10 mi or more.

From the Field Book

FB-SKY-001, Fig. ACloud classification
The ten cloud genera by height: the etages these layers fall in.
FB-SKY-017, Fig. AStratus
A cloud with its base at 2,100 ft is in the low etage, where stratus forms.
FB-SKY-016, Fig. AStratocumulus
A cloud with its base at 2,100 ft is in the low etage, where stratocumulus forms.
FB-SKY-018, Fig. ACumulus
A cloud with its base at 2,100 ft is in the low etage, where cumulus forms.
FB-SKY-013, Fig. AAltocumulus
A cloud with its base at 6,500 ft is in the middle etage, where altocumulus forms.
FB-SKY-014, Fig. AAltostratus
A cloud with its base at 6,500 ft is in the middle etage, where altostratus forms.

2The air

Contents

79.0 F with a dew point of 75.0 F, 88 per cent relative humidity. Air lifted from the station would cool to its dew point, where cloud forms, about 900 ft up; the lowest cloud reported is at 2,100 ft.

From the Field Book

FB-WAT-020, Fig. AFog types
The temperature within 4.0 F of the dew point: the air is close to fog.
FB-WAT-002, Fig. CHumidity variables
The same lift, worked for another air: how the humidity climbs as the air rises and cools.
FB-ENG-011, Fig. AWater vapour as a gas
How much vapour air can hold at each temperature, which sets the dew point.
FB-ENG-005, Fig. ALapse rates and stability
The dry rate the lifted air cools at, against the air around it.

3The wind

Contents

From the northeast (40 degrees) at 7 mph: force 2, a light breeze on the Beaufort scale. The strongest gust today was 18 mph.

From the Field Book

FB-EVT-150, Fig. AHigh wind
How 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 geometry
Why large scale winds turn, and blow round a low rather than into it.
FB-INS-002, Fig. AASOS
The mast the wind is measured on, 33 ft above the ground.

4The column

Contents

At 39 ft above sea level, 0 per cent of the atmosphere's air lies below the station. The standard atmosphere puts the pressure there at 29.88 inHg and the temperature at 58.9 F; the station's altimeter setting of 29.96 inHg means its barometer reads 29.92 inHg; it reports 79.0 F, 20.1 F warmer than standard.

From the Field Book

FB-ENG-001, Fig. AAtmosphere in section
The whole standard atmosphere this station stands in, from the ground to the edge of space.
FB-ENG-003, Fig. CHydrostatic balance
Why a barometer 39 ft up reads less: it weighs only the air above it.

5The sun

Contents

On Oct 16 the noon sun stands 63 degrees above the horizon at 18.26 N, and the day is 11 h 36 min long. Level ground there takes 89 per cent of the noon sunlight a surface facing the sun would.

From the Field Book

FB-ENG-007, Fig. ARadiation budget
Where the sunlight that reaches this ground goes once it arrives.

6The instrument

Contents

An airport station, 39 ft above sea level. Its report of Oct 16, 2026, 1:04 AM local time is written on the sensors that made it.

From the Field Book

FB-INS-002, Fig. AASOS
The airport station in full: every sensor, and how long each reading is averaged.
FB-INS-001, Fig. AWhat an instrument is
A surface station taken apart: what each of these sensors is.
FB-INS-009, Fig. AStevenson screen and siting
Why the thermometer sits in a shield 5 ft over grass.
