Nov.04-05Sunny

Most of the instruments and observations are working well.

The sky is very clear in Nov.4, while covered by scattered cumuli and congesti in Nov.5. From evening on Nov.4 to morning on Nov.5, widespread meso-alpha-scale radar echo appeared in the south of Mirai, but vanished in daytime. The "RS92-detected upper-tropospheric humidity" decreases, while middle and lower troposphere gradually become moist.

In the ocean, the top 40m become warm and less saline, with the diurnal signal in the temperature. The significant thermocline have been existing, however, at about 100-m depth.
