I thought he was querying the 13mm figure. The other stuff seemed more
reasonable for the area. Was there a typhoon coming ashore?



No I was realy querying the 944 figure, the the reports are for the
previous 24 hours, hence each one changes.

Incidentally, someone mentioned the maximum ever fall in 24 hours of
1270mm, where and when did that occur?

All the really big documented falls are from Reunion Island in the South
Indian Ocean. All occurred in association with tropical cyclones.

Thanks Norman,

I was just wondering, how do you report totals over 1000mm in the
synops?

I *think* that the only mechanism currently is to report it in the
Section labelled 333 in the 24 hour total group ... 7R24R24R24R24, where
that amount would be in

milllimetres. I'm not sure if India use that group though ... there is
no mention of it in the 'National' section of the WMO Manual of Codes
for India.

INDIA

6RRRtR This group is used in the form 6RRR/, RRR indicates the amount of
precipitation which has

fallen since 0300 UTC. When reported, group 6RRR/ is included in Section
3.

India doesn't use the 24 hour code 7****, however, the maximum that can
be reported is 999.8mm, 79998, because 79999 = Trace. Unless they add
another digit to the group, but I don't think that can be done.

Yes India use this group.
/ indicates past 24 hours, some Countries use a 4 at the end.
Similarily, 6999/ = trace, 6998/ = 998mm

fallen since 0300 UTC. When reported, group 6RRR/ is included in Section
3.

.... I thought there was a means of converting the R24R24R24R24 into mm
only, but can't find the reference. If I do, I'll post it on.

Good question, Keith. In the 6-group the highest total that can be
explicitly reported is 988 mm. Code figure 989 means 989 mm or more,

.... no, my mistake. I was confusing the reporting of rainfall in SYNOP
with that in other forms such as CLIMAT and HYDRA, and in the latter
specifically, Code 3596 does report rainfall in whole mm, but for period
of 'x' days, where x is usually segments of a month. As you write, there
does not seem to be a method of reporting such high rainfall totals in
the *SYNOP* code.
