Thanks Norman,
I was just wondering, how do you report totals over 1000mm in the synops? Keith (Southend) Norman Lynagh wrote: All the really big documented falls are from Reunion Island in the South Indian Ocean.

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. Martin. |

In message . com,
"Keith (Southend)G" writes Thanks Norman, I was just wondering, how do you report totals over 1000mm in the synops? Keith (Southend) 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, Norman.

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.
