Fine. Southeasterly (about 8m/s) prevailed. Cloud clusters, which moves
westward, can be monitored in the north of Mirai. Cloud images taken by
satellite shows zonally extended cloud band. Radiosonde sounding shows
CAPE higher than 1000 J/kg, and total precipitable water vapor gradually
increased over 45 mm.
Three-hourly routine measurements continue. Most of insturments properly
Photos - During the cruise, we hold seminars to learn about the
observations conducted on-board. In addition, it is a good opportunity
to know each other. Today a scientist from Univ. of Hawaii/IPRC made a
presentation entitled "Ocean/Atmosphere interactions in the tropical
Indian and Pacific Oceans". Actually, he started to show the basic
features of the Indian Ocean, then report the current cruise results,
and also showed some results obtained by previous Mirai cruises in the
western Pacific with some numerical model studies.
As for the observations, two scientists from IPRC are in charge of LADCP
measurement, which is attached to CTD and has been conducted every 3
hours, to study ocean surface structure by a combination with MSP data.
