Re: The Passing MJO through Indonesia Maritime Continent

Pak Ardhi, Very good spirit and approach. You look to become a
good observational scientist already. Your indicated arrow
starts near 100 E at 18 UT on Dec. 1, and ends near 130 E at 12
UT on Dec. 5, which implies an eastward propagation of 3330 km
per 90 h = 37 km/h = about 10 m/s.
You could also find smaller-scale disturbances as especially
large rainfalls. You also notice some of them are near coasts
of Sumatera (100 E, 105E), Kalimantan (110E, 120E) and Papua
(130 E, 150E), and also near local afternoon-evening (06-18 UT).
So the next step is how the structure of precipitating clouds
originally included in the ISV (MJO) were modified near each
coastline and around sunset. Yes, you have understood that
you must be able to check the MPR data observed by yourself
at west Sumatera.
Cheers!

As you could see, high precipitation was occured in the beginning of IOP around the western part of Indonesia and moves towards east (Western Pacific). I have not checked the present GSMaP data, but by looking at the figures, i suppose the high precipitation should reach Papua area by now.
