Fake Climate Records

Post by Glacier » Wed Feb 05, 2020 11:00 am

Here is a thread for discussing likely climate errors.

I'll go first. Castlegar supposedly had a humidex of 53.4 on 1961-07-14 15:00:00 PDT.

I know it can be humid and hot in the Kootenays, but this just seems really unlikely! That would be a Canadian record. We are talking a dew point of 29.4, which would be a Canadian record as well. The temperature was 35.6C.

The highest dew point outside of that summer was on June 6, 1967 at 23.9. Even that value seems suspiciously high. The highest recorded since 1967 was 21.6, set on August 1, 1998.

So what was the highest humidex ever recorded at Castlegar? It would be 44, set July 31, 2009 (dew point was 18.6 and the temperature was actually hot at 37.4C).

This is inline with other southern interior hot spots:
- Trail = 41 (set in July 2006 and July 2013)
- Penticton = 43 (set July 2nd, 2013), with dew point at 19.1 and temperature at 36.2C
- Vernon = 42 (set June 29, 2008), with dew point at 14.1 and temperature at 38.5C
- Salmon Arm = 45 (set July 2, 2013)
- Kamloops = 42 (set July 24, 1994), with dew point at 13.2 and temperature at 38.4C
- Ashcroft = 41 (set July 1, 2013), with a dew point of 10.7 and a temperature of 39.1C
- Osoyoos = 46 (set in both 1998 and 2004). The most recent on June 22, 2004 had a dew point of 16.2 and a temperature of 40.9.
- Lytton = 45 (set in 2006), dew point at 14.0 and temperature at 41.9
- Kelowna = 43, set July 22, 1971 (34.4C with dew point of 21.7 and humidity of 48%).
- Lillooet = 39, set several times since records began in 2013. One example is a temperature of 40.5 and a dew point of 0.9 and a relative humidity of 9%!

- Nakusp = 44, set July 5, 2007, dew point of 19.4, temperature of 37.2
- Nelson = 42, set 2006 and 2007
- Creston = 47, set July 12, 2002 (BC record?)

OTHER LOCATIONS:
- Puntzi Mountain 35, set in 1997, 1998, and 2006. (Temperature 33 to 34.7 with the dew point 7.5 to 12.2)

NOTES:
- The official Kamloops record of 47 is also bunk. In 1957 the temperature was 31.1C and the dew point was 28.3C? In Kamloops? No way in heck!
- Ashcroft, Lillooet, and Puntzi Mountain are the only places in Canada I can find where the extreme max temperature is HIGHER than the extreme high humidex!
- The Kelowna record Humidex is also fake in my view. The data from 1964-65 is crazy. 33 degrees with 68% humidity, and a humidex of 46? I don't think so!

Pemberton's extreme humidex is also fake. The 2004 data is completely fake, and in fact, we can see this because an error occurs when the humidity is well over 100%. The 52 humidex from 2004 is wrong. The most humid it has been there is 46, set on July 27, 1998. Temperature 39.8 and dew point 17.9.

Abbotsford's record of 46 is also suspect. Set a couple days before Castlegar's fake value. I'm more included to trust the 44 set on July 21, 2006.

Back in the days of wet bulb thermometers and manual measurements... what could go wrong? :lol:

LOL... although, I must say that automated precipitation recording is far less reliable than manual. FOR EXAMPLE: Puntzi Mountain (one of the driest places in BC) has supposedly had precipitation for like 150 days in a row now!... https://climate.weather.gc.ca/climate_d ... ionID=8092

Yup, there's not a lot that can go wrong with a manual rain gauge... no moving parts or electricity, no calibration needed, no math or programming required. Any problems are likely to be caught far more quickly because someone is actually checking the gauge regularly.

Dew point on the other hand is hard to measure at the best of times. Correct use of a wet bulb thermometer is critical, and there is some math required. The more it can be automated, the less room for error.
