The difference between the reference and a sample is that the concentration of the measurable substance in the reference solution is zero. The reference tube transmits as much light as is possible with the solution you are using.
Rate this Article: The Saffir-Simpson Hurricane Scale is a 1-5 rating based on the hurricane's present intensity. This hurricane scale is used to give an estimate of the potential property damage and flooding expected along the coast from a hurricane landfall. Wind speed is the determining factor in the scale, as storm surge values are highly dependent on the slope of the continental shelf in the landfall region. Wind speeds are measured using a 1-minute average. Note:The Saffir-Simpson Hurricane Wind Scale (SSHWS) was updated in 2012 to accomodate number rounding issues.
The SaffirâSimpson hurricane wind scale (SSHWS), formerly the SaffirâSimpson hurricane scale (SSHS), classifies hurricanes â Western Hemisphere tropical cyclones that exceed the intensities of tropical depressions, and tropical storms â into five categories distinguished by the intensities of their sustained winds.he highest classification in the scale, Category 5, is reserved for storms with winds exceeding 156 mph (70 m/s; 136 kn; 251 km/h). The classifications can provide some indication of the potential damage and flooding a hurricane will cause upon landfall.
