Question

When you have VV, does this mean only 6 Oktas of the sky are covered?
A) True
B) False

Answer 1

The statement is false, 'VV' means the sky is completely obscured which indicates 8 oktas are covered, not 6.

Step-by-step explanation:

The statement is false. When 'VV' (vertical visibility) is noted in a weather observation such as METAR, it refers to the situation in which the sky is completely obscured, such as in heavy fog or cloud, and the observer cannot see the sky above. This means that essentially 8 oktas of the sky is covered and visibility is restricted vertically. 'Oktas' is a term used to describe the amount of the sky dome that is covered by cloud. One okta represents one-eighth of the sky covered, so 8 oktas mean that the entire sky is covered.
