Cumulus Support

Hi Steve,

At one point there was some questrion as to whether Cumulus would show below zero temperatures with fine-offset.

Just to confirm it can!!!

Steve, with your wonderful manipulation of the weather, could you make it a bit warmer please!

Thanks for confirming that, Bob.

Facilities for altering the weather rather than just recording it, will be coming in Cumulus 2.

I am seeing some "funny" graphs after a frosty night: The period 1:30 - about 9:00 shows no wind at all, and a wind direction of North all the time.
It was a very calm night - but that calm
Maybe the wind speed indicator was stuck due to frost.
But the wind direction indicator was not: the easyweather.dat file has several entries of other directions than north.
Steve: could it be that, when you see a wind speed of 0 you just decide a wind direction of 0?

No, I don't think I've implemented that, but it's actually correct, I am told. As part of my investigation into whether North should be zero or 360, I found that zero wind direction should be reported when wind speed = zero.

However, if the station is reporting an invalid bearing greater than 360, I change this to zero, so maybe this is what happened. And I've realised that with the change I've just done to report 360 instead of zero, I will change this zero into 360 also, so I need to have a look at that. Always complications...

It occurs to me that if you still have the Diags file for the relevant start-up, we can see exactly what values the station was supplying for bearing at that time.

Steve

here's the Diags file from the time, and an extract from the EasyWeather.dat file for the same period.

It is supplying directions, but a speed of zero. I've realised that I effectively do log a bearing of zero when the wind speed is zero, because the beraing in this case is the average bearing, which takes into account the wind speed. So zero wind speed = zero average bearing, which is correct.

Except that I've just broken that in my changes to display zero as 360 . Fixed next build.

I fired Cumulus up at around 21:00, it showed at 18:00 a glitch in the temperature graph. A sudden fall to -9.2 whereas the rest either side were 9.3 /9.2 plus values. I edited the single minus value in the Nov08 file to plus in the log, saved it - which sorted the graph out, then ran Cumulus to edit what had become a record low, in the 'edit' 'all time records'. I'm still stuck with a -9.2 in my 'Recent Extremes', is there a way to edited this out please?

Harry, it would have been in today.ini. Depending on when you've run Cumulus since you posted, it may now be in yesterday.ini instead, and have also found its way into dayfile.txt

Thanks Steve, all now sorted out - and before I started Cumulus up today.
