Circumpolar winds

WebWest wind drift or Antarctic Circumpolar Current (ACC) is a southern hemisphere current that moves from west to east at around 40°-55°S in clockwise direction due to prevailing western winds. It circles the globe, passing through the Atlantic, Indian, and Pacific oceans; in the oceans, the chilly Bengal, West Australian, and Peru currents branch off from it. WebThe UBV photometric system (from Ultraviolet, Blue, Visual ), also called the Johnson system (or Johnson-Morgan system ), is a photometric system usually employed for classifying stars according to their colors. It was the first standardized photometric system. The apparent magnitudes of stars in the system are often used to determine the color ...
