Mind blown !

So virtually no heat from the engines, cool. Even less than 0.04 degrees.

Where have you got this 0.04° figure from?
Without looking up the exhaust temperature from a jet engine I can guarantee you that it's way, way, way higher than that.

I think it was based on the energy released by the fuel burnt during take off heating the air in an imaginary box behind the plane.

Ah yes, I kind of remember it now.
So almost of no significance whatsoever to the effect a jet engine would have on temperature readings shown by a weather station next to a runway, if the wind was blowing in the right direction.

Better than your biased and baseless hunch though, eh?

What? You mean the jet engines melt the tarmac as they are taxiing to the runway?

Surely the effect would be fleeting. It would only matter if it happened at the exact time the record high temperature was recorded.

It isn't.

Well it's worse than that because as denso is trolling on it is not a runway but a transit way and they trundle past slowly. So it's not a fleeting moment

I have been trying to work out whether the speed they go past the station is important. Slowly means more time, but also less fuel being burned. It's a conundrum.

We've been through this before. You were wrong the first time as well.

 

[aveatry]

The readings already artificially high because of the proximity to concrete and tarmac and then a jet trundles past, and the readings are contuinious so it doesn't need a jet to go past at any particular time and the time of day of the poster boy high reading is a time when the jets are active.

 

[denso13]

It's a conundrum.

It really isn't. Any outside influences are taken into account when verifying temps.

 

[aveatry]

How.
Do they just knock a degrees off to compensate for the concrete and tarmac. And then one near a cold river do they add a few degrees

 

[denso13]

How.

Email them and ask.

Are you seriously trying to suggest that high temperature anomalies caused by passing aircraft exhausts are responsible for high temperature readings and that as a result, global warming is a scam?
