Find the depth of rainfall from a storm of duration 6 hours and return period 10 years on a catchment of 5 km 2 in Sheffield. From the FSR maps, the M5-60 minutes rainfall is 20.5mm, and "r" = 0.4. Divide 20.5mm by 0.4 to get 51.3mm, which is the M5-2 days rainfall depth.
The hourly PoP is the probability that more than 0.01 inches (0.25 mm) of precipitation would occur if conditions like those in the given hour continued for twelve hours. It can be similar to the daily PoP and vary little, or it can vary dramatically. the daily PoP will be the average of the hourly PoP across the whole day.
= 4.1 R-0.21 mm −1 (equivalent to 41 R-0.21 cm −1 in the reference [4]), R being the rainrate in stratiform precipitation in millimeters per hour; D = raindrop diameter in mm The units of N 0 are sometimes simplified to cm −4 but this removes the information that this value is calculated per cubic meter of air.
The scale of dBZ values can be seen along the bottom of the image. Decibel relative to Z, or dBZ, is a logarithmic dimensionless technical unit used in radar. It is mostly used in weather radar, to compare the equivalent reflectivity factor (Z) of a remote object (in mm 6 per m 3) to the return of a droplet of rain with a diameter of 1 mm (1 mm 6 per m 3).
