Nothing but blue

We had fine weater today. Southeasterly (8m/s at the surface) prevailed and swell remains. Radiosonde sounding shows the existence of very dry layer around 600 hPa. CAPE is low less than 500 J/kg during past 2 days, and total precipitable water vapor decreased to 45mm.

Three-hourly routine observation continues. In terms of measurement systems, most of them are properly working. Some instruments (person in charge is not on-board) are sometimes stopped.
