Wind measuring has been standardized globally to reflect the winds at 10 metres (33 ft) above mean sea level, [nb 1] and the maximum sustained wind represents the highest average wind over either a one-minute (US) or ten-minute time span (see the definition, below), anywhere within the tropical cyclone. Surface winds are highly variable due to ...

By contrast, the U.S. National Weather Service, Central Pacific Hurricane Center and the Joint Typhoon Warning Center define sustained winds as average winds over a period of one minute, measured at the same 33 ft (10.1 m) height, [16] [17] and that is the definition used for this scale.
At the bottom of the scale was Category 1, for storms with sustained winds of 74 to 95 mph. At the top was Category 5, for disasters with winds of 157 mph or more.
What is the Saffir-Simpson Hurricane Wind Scale? The Saffir-Simpson scale matches wind speeds with examples of the type of damage and impacts those winds could cause in the USA.
Also actiniform. Describing a collection of low-lying, radially structured clouds with distinct shapes (resembling leaves or wheels in satellite imagery), and typically organized in extensive mesoscale fields over marine environments. They are closely related to and sometimes considered a variant of stratocumulus clouds. actinometer A scientific instrument used to measure the heating power of ...
That is, that a scale that tops out with Category 5, capturing any storm with sustained winds at 157mph or more, underestimates in the public’s mind the actual threat of much more powerful ...
A mathematical symbol is a figure or a combination of figures that is used to represent a mathematical object, an action on mathematical objects, a relation between mathematical objects, or for structuring the other symbols that occur in a formula. As formulas are entirely constituted with symbols of various types, many symbols are needed for ...
