Was the explanation of wind speed written by a European? The punctuation after "18" is a comma, not a period, so they it means over 18 thousand knots. Barmar (talk) 19:59, 13 December 2024 (UTC)

Yes, it was. I'm sorry. Janfred (talk)

If windspeed interpreted at "european style", i.e. 18 and 35/1000 knots, it s still funny, beacouse such precision of wind speed measurement is 1] unreachable (variability at space & time is several horders higher), 2] useless (fraction of knot make no difference for pilots). ([[HonzaM])

"38.08 inches of mercury" seems a very high pressure, even for a station that is well below sea level. (1290 hPa Pressure around the dead sea is typically 1060hPa).. Is that physically realistic, or is it part of the joke? I know funnel clouds, freezing and volcanic ash in the same location are unlikely outside of the apocalypse, but can be justified by the rule of funny. 172.70.160.135 20:11, 13 December 2024 (UTC)

Indeed, 31.80 is the reference high limit. Still, is Randall a pilot? The structure of a METAR is horribly familiar to us pilots but pretty much a blank stare to anyone else. 172.68.245.25 21:03, 13 December 2024 (UTC)

Feeding it into a calculator gives an altitude of -2080m (-6825'). So it's entirely reasonable as long as your weather station is in a deep mine. BunsenH (talk) 21:08, 13 December 2024 (UTC)

But isn't the value always put in reference to MSL? I.e. I'm at an airport at 1000ft, the pressure reads 977 hPa, but I'll put 1013 hPa in the METAR. (QNH in METAR vs QFE at the station) Janfred (talk) 21:14, 13 December 2024 (UTC)

There may be various complicated pressure differences from the tornado having dumped a load of possibly Iclandic pyroclastic tephra upon the station. 141.101.98.181 21:36, 13 December 2024 (UTC)

"outside of the apocalypse" - we are talking about NYC :P 172.69.64.171 00:04, 14 December 2024 (UTC)

The difference between the altimeter setting and the SLP is also pretty concerning. My understanding (which is based only on a few minutes of googling, not any actual experience) is that one does not correct for temperature while the other does, based on a 12 hour average. So maybe the high value is due to crazy temperatures? Haven't done any calculations, but it would fit the apocalyptic scenario. 172.70.247.9 08:40, 14 December 2024 (UTC)

That sounds about right for the weather station located at the ZIP code -10021... 172.70.91.11 09:37, 14 December 2024 (UTC)

llama-3.1-405b-instruct (poor context, likely contains mistakes):

New York, Central Park: 25th of the month, 16:00 UTC (11:00 am local time): Wind from the south at 35 knots (about 40 mph), with gusts up to 45 knots (about 52 mph): 6 statute miles visibility: In the vicinity, a funnel cloud and freezing volcanic ash: Heavy blue precipitation: No significant change in weather expected: Lightning overhead: Altimeter at 38.08 inches of mercury (about 1022.8 hPa): Precipitation discriminator present: Sea-level pressure at 1013.0 hPa (30.00 inHg, but note that this value is not explicitly stated in the METAR report, and the 'SPL130' code is not a standard way to report sea-level pressure).

...

I should have mentioned that the codes "+BLUP" are not standard METAR codes.

METAR is specified by the International Civil Aviation Organization (ICAO) in the document "Annex 3 to the Convention on International Civil Aviation: Meteorological Service for International Air Navigation". This document defines the standard format and codes used in METAR reports.

In the United States, the Federal Aviation Administration (FAA) also publishes guidelines for METAR reporting in the document "Aviation Weather Services Advisory Circular" (AC 00-45).

The World Meteorological Organization (WMO) also publishes guidelines for METAR reporting in the document "Manual on Codes" (WMO-No. 306).

These documents define the standard codes and formats used in METAR reports, but they do not include codes like "+BLUP", which are likely used in a humorous or fictional context.
