Muara Putus MPR Observation Report Dec 15, 2011

Dear colleagues,

MPR is detecting medium to heavy precipitation around Mentawai islands right now, especially in Siberut and Sipora island. The wind is blowing southeastward, between 5-10 m/s.


We were switching the power supply mode from manual (generator) to automode (PLN+generator) after several errors (antenna and generator fault) occurred this morning. Anyway, PLN power supply seemed to be fine and MPR is working well until now.

Best regards,

-ardhi-

Invitation to "Friends of SATREPS"

Dear Indonesian colleagues
(Sorry if you have received similar e-mails several times)

As the almost mid-point of the IOP-HARIMAU2011, I would like to
acknowledge your collaborations on behalf of the Japanese team.

On this opportunity I would like to introduce an SNS-website
called "Friend of SATREPS":

https://fos.jst.go.jp/

which covers all (60 or more) SATREPS projects over the world.
and the community of our (SATREPS-MCCOE) project is

https://fos.jst.go.jp/community/115

on which the HARIMAU2011 blog-site is of course linked.

Please visit them if you can access the internet even at each
observation station. A registration would be requested, but
simple minimum answers of your personal information is enough.

Also please register our community. Please visit

https://fos.jst.go.jp/community/115

and click "Join this community" button at the bottom.

YOUR REGISTRATION TO OUR COMMUNITY is truly important TO GET
MORE GRANT from JST for our future collaborations.

Thanks in advance for your kind collaboration on this issue.
Also I would like to express sincere acknowledgment for your
collaborations in HARIMAU2011.

Coastal Heavy Rainband (CHeR) on Dec.12

Dear all:

Sorry for my long silence because of many troubles with the UAV flight
observation. Please refer to reports from Hattori-san about the troubles.

I would like to introduce of a case of coastal heavy rainband (CHeR)
observed in the early morning on December 12. If you have a broad band
network, please check out the following animation image:

http://turbulence.ddo.jp/morishu/harimau2011/mia_xdr_cappi2kmz111212.gif

Weak echoes were started to be observed after 0600LT, and then they were
integrated as a CHeR line inwith parallel to the coastline by 0800LT.
The CHeR was generated and maintained along a weak convergence zone
between southerly and southeasterly winds blown from Mentawai and
Sumatera Islands, respectively.

The CHeR has been weaken and spread after 0930LT when wind from Sumatera
Island changed its direction from southeasterly (land breeze like
direction?) into southerly (see breeze like direction?).

A vertical cross section view of CHeR (RHI for 225deg) shows inbound
flow (southwesterly component) below 4-5 km with very small convergence
in its northeastern side, and out flow (northeasterly component) above
it. This strong vertical wind sear may have an important role to
generate and maintain the CHeR, too.

I welcome your comments and further discussion.

Originally, we would have planned to make a UAV flight observation which
penetrates the CHeR from Tabing to Sipora by different altitude to
examine environmental condition in and out of the CHeR! Huuuum.

Re: Re: Re: Re: Re: BJ-III on stationary observations

Dear colleagues,
BJ stationary observations has been intensified as 8 times/day
rawinsonde launch from 00 UT (07 WIB) today until just before
leaving from the stationary point at 12 UT (19 WIB) tomorrow.

Clouds have increased again, and rawinsonde observations show
increase of moisture again. Wind is W about 5 m/s, and wave
is about 1 m.

Until now only one rawinsonde sensor/transmitter was bad.

Regards,
MDY
