Hurricanes are classified according to intensity using the Saffir-Simpson Scale.

Explanation:

A hurricane’s sustained wind speed is measured on Saffir-Simpson Scale. from 1 to 5. It can also predict the potential damage that the hurricane can cause with its strong wind spirals. As the levels signify categories as per the amount of destruction they cause, such a scale becomes of prime importance. Category level 3 hurricanes and above cause heavy loss of life and property, so detecting such catastrophes help in taking measures that can save lives and prevent future losses.

a maximum–minimum thermometer. the scales are fahrenheit on the inside of the u and celsius on the outside. the current temperature is 23 degrees celsius, the maximum recorded is 25, and the minimum is 15, both read from the base of the small markers in each arm of the u tube. the bulbs are hidden by a plastic housing.

six's thermometer is a registering thermometer which can record the maximum and minimum temperatures reached over a period of time, for example 24 hours. it is used to record the extremes of temperature at a location, for instance in meteorology and horticulture. it was invented by a british scientist james six, born in canterbury, in 1780; [1] the same basic design remains in use.

it is also commonly known as a maximum–minimum, minimum–maximum, maxima–minima or minima–maxima thermometer, of which it is the earliest practical design.

the thermometer indicates the current temperature, and the highest and lowest temperatures since last reset.
