#1191 closed defect (invalid)

empty lightning diagnostic

Reported by: s1251469 Owned by: um_support
Component: UM Model Keywords: ukca
Cc: Platform: HECToR
UM Version: 8.2



I'm running a copy of the basic UKCA tutorial but outputting lightning diagnostics to give me a feel for them.

When I output the total flashes (2D) and total N (2D) I have empty fields. Strangely the 3D lightning NOx emissions contain some non-zero numbers which may well be correct- I'm not sure. I have output other variables which have worked fine.

I am aware of the bugfix but when I look in ukca_sed1defs.F90 it seems like the diagnostic cloud base and top are being used.

my job is xjhxa.

Dear Declan,

Only the emissions diagnostics 34381 is actually configured to work in the code. All the other lightning diagnostics will not work and should only produce zero fields.

You should note that the UKCA job used in the Tutorial is not designed to be used for scientific studies and may not produce meaningful results. I would advise you to use one of the standard release jobs at

for scientific studies. Any new jobs released will be updated here and advertised when they available.

Many thanks,
