The YMC-BSM 2018 at EAR is close to its end. During the observation campaign, AWS (*Automatic* Weather System) and Gas Cylinder sometimes do not work well. We launch special sondes with the help of local staffs. The photos show a man checking the AWS and Sate Padang. (tk)
We eat breakfast at the hotel and dinner at some restaurants near the hotel in Bukittinggi during YMC-BSM 2018. The restaurant is where S-san visited during Pre-YMC campaign in 2015. The photos are taken at the breakfast at the hotel and diner the day before yesterday. (tk)
We have been conducting upper air ozone and water vapor soundings in Ho Chi Minh and Hanoi, Vietnam in collaboration with Vietnam Meteorological and Hydrological Administration. The purpose of this observation is to clarify the ozone and water vapor exchanges between the mid-latitude stratosphere and the tropical troposphere associated with the Asian summer monsoon circulation. We started the observation on June 29 at the Ho Chi Minh observatory and on July 2 in the Hanoi observatory, and have been launching the balloons once in two days at the both observatories. (SYO)
This is the first time visiting EAR station. We can see Yagi antennas more closely compared with MU radar at Shigaraki station. From today to tomorrow, we prepare the receiver systems and will start to observe day after tomorrow. Another photo is the special ice cream during the flight. (tk)
Laoag is a coastal city facing the South China Sea in the northwest of Luzon Island, Philippines. There is a weather station of PAGASA nearby Laoag International Airport, where SYNOP and twelve-hourly radiosonde observations are usually performed.
As a part of the YMC-BSM2018, JAMSTEC, PAGASA, and UP are jointly conducting an intensive observation campaign in July and August of 2018 at the weather station. It consists of six-hourly radiosonde sounding during the two-month period, X-band weather radar observation in August, and inter-comparison of radiosonde sensors manufactured by several companies.
I have visited Laoag and commemorated the start of the campaign by doing a kind of “balloon release” ceremony, using a balloon (with sensor/transmitter) for the first radiosonde observation :P.
The images are (upper left) the Laoag weather station, (lower left) “balloon release” ceremony, and (right) data of the first radiosonde.
YMC-BSM (Boreal Summer Monsoon study in) 2018 – one of the YMC’s Intensive Observation Periods – has been started since July 1, 2018. It will continue until the end of August, and various observations such as radiosonde atmospheric sounding and weather radar rainfall measurement will be conducted at Laoag (Philippines), Aimeliik (Palau), Kototabang (Indonesia), Hanoi and Ho Chi Ming (Vietnam). In addition, three unmanned surface vehicles have been launched from Palau to study air-sea interaction in the Philippine Sea.
This campaign is conducted based on the collaboration with the local MC agencies, institutes, and universities including PAGASA, University of the Philippines (Philippines), Koror Weather Service Office (Palau), LAPAN (Indonesia), and National Hydro-Meteorological Service (Vietnam).
Since JAMSTEC colleagues visit those countries in a short period (because most observation will be done by the local collaborators), this blog may not cover successive topics from any specific site. Rather, it will be a collection of reports from various sites (and sometimes it may contain the report after he/she returns to Japan).
