5 February 2002:  rainfall over Jakarta

Gedday,

Does anyone up in the Darwin Office have any information on the Jakarta
flooding event?, e.g... Rainfall amounts, synoptics of the situation?

Going by press reports, it started raining heavily on Thursday last and
kept up for four days.

Me again.... I just had a quick look at TLAPS Darwin site, which stores
the analyses for the past seven days:  looking at the 850 analysis for
0000GMT on Wednesday the 30th there was a massive Northeasterly surge
across the South China Sea and surrounding regions.  This resulted in (or
to be more precise, was followed by) a tiny little (about 1 degree
latitude across) low level jet along Java, Bali, Lombok for about the
following 4 days.

See sequence of 850 hPa charts below:

Looking at the Indonesian Newpaper sites on the web, it seems the floods
began way back on Monday-Tuesday of last week, with Kompas of last
Wednesday morning (30 Jan) reporting two dead and 40,000 evacuated from
areas of Jakarta, Tangerang and Bekasi.

The graphs on WeatherOnline (http://www.weatheronline.co.uk/ ; a very useful
resource for recent global climate data!) suggest the following for Jakarta:

27/1    50mm
28/1    105
29/1    15
30/1    0
31/1    missing
1/2     missing
2/2     13
3/2     0
4/2     missing

I wouldn't have thought there was anything particularly extraordinary about
these numbers and can only assume there must have been very heavy rain on
one or more of the three days with missing data (or alternatively much
heavier rain in catchments upstream?)
