Report from MPR site (24 Dec 2011)

According to the daily check sheet, the following errors appeared last
night.

1724 LT on 23 Dec 2011, blinking
2303 LT, PLN off
2320 LT, GDRX-SP error
2340 LT, GDRX-SP error
0003 LT on 24 Dec 2011, GDRX-SP error
0051 LT, GDRX-SP error
0140 LT, GDRX-SP error
0756 LT, PLN off -> generator
ACU AZ servo error
ACU EL servo drive overload
ACU EL servo motor overload
2F5 fuse off and on
0850 LT, restarted
0920 LT, GDRX-SP error
1007 LT, GDRX-SP error

After PLN power failures, radar system became unstable (not only last
night). Errors of AZ/EL servo drives and GDRX-SP appeared many times.
Because of this, the team MPR decided to deactivate auto mode and to
operate the radar using only generator power again. (Still in auto mode,
but unplugged the PLN cable.

NHM simulation

Dear all:

Please find out figures attached herewith.

They are results numerical simulation based on GSM 0.5deg (upper left),
NHM 10km (upper right), and NHM 2km (lower left) for 18Z 23 December
(01LT 24 December). MIA-XDR CAPPI(2km) at the corresponding time (01LT
24 December) is shown in the lower right panel, too.

The result of GSM simulation looks successfully showed a large scale
disturbance approaching Sumatera which was also observed by GsMAP in my
last post. Whereas, those calculated by NHM for both 10km and 2km didn't
show any precipitation at all in those domain though the MIA-XDR
observed rain echoes broadly expanded around Padang.

It looks curious that precipitation calculated by HNM

cannot enter the Mentawai Strait though GsMAP, GSM, and MIA-XDR showed
large scale precipitation over the strait. Huuuuum.

Summary of MIA-XDR status

Dear all:

Sorry for long silence from Tabing/Padang.

An engineer for UAV operation goes back to Japan today. Th other two
engineers still stay in Padang, however, their duty has already finished.

I myself have been trapped to make many reports about the UAV accident
so far.

Anyway, I've been in MIA-XDR site and checked and checked archived data
so far. Here is a summary for MIA-XDR status ([ ] period of no data):
---
Nov.26-30: Ok
Dec.01-07: Ok
Dec.08: [1110, 1130-2350]
Dec.09: [0000-1000]
Dec.10-11: Ok
Dec.12: [1400]
Dec.13-18: Ok
Dec.19: [1910-1950]
Dec.20-23: Ok
Dec.24: [01130-0250]
---

Most of no data period looks to be cause by generator failure problem
during the PLN blackout. Sopia-san told me that engineer(s) will cometo
fix it on this weekend.

Here are latest figures of GsMAP and MJO Index. A large scale
disturbance is approaching Sumatera again.

best,
