339 : Reader Marcus from Louisville wrote in to ask, What's the differentiation between predictions? Are any of them conditions that are even defined? The answer: approximately 1 to 4 oktas. What's an okta? Thats a unit of measurement that meteorologists use when theyre forecasting cloud conditions, equal to 1/8 of the sky. When the prediction is delivered, the amount of oktas covered by clouds is clarified with sunny, partly cloudy to hearing were used alongside other terms. The National Oceanic and Atmospheric Administration and that the National Weather Service defines these to oktas of cloud cover with regards. The NWS Operations Manual breaks down it like this: Daytime Forecast - Day or night forecast - Cloud Conditions - sunny - Cloudy - 8/8 opaque clouds - Mostly Cloudy - Mostly Cloudy - 6/8 - 7/8 opaque clouds - Partly Sunny - Partly Cloudy - 3/8 - 5/8 opaque clouds - Mostly Sunny - Mostly Clear - 1/8 - 2/8 opaque clouds - Sunny - Clear - 0/8 opaque clouds - The difference in terms is a question of all how much cloud cover there is.

Partly sunny and partly mean the same thingbut since you can't find the sunlight, cloudy is the term for night conditions. Fair skies is just another cloud cover term thats occasionally used. Technically, it implies that less than 3 oktas are covered with opaque clouds, and that theres no precipitation, no extreme requirements of visibility, wind or temperature, and usually pleasant weather. If you do not Know that definition, however, fair sounds pretty vague by itself, so the NWS discourages users from using it. Lots of terms utilized in precipitation predictions are also Precisely defined by that the NWS and are less subjective than they occasionally sound. #photography #iphoneonly #art #artistsoninstagram #art_spotlight #artesanato #arts #artofinstagram #artwork #kids #kidart #kids #kidsartwork #photography #iphoneonly #art #writing
