The rainfall rate is a measure of the intensity of precipitation. It is the amount of rainfall received in a given time period usually an hour. The rainfall rate is usually expressed in inches per hour.
Heavy rainfall can cause flooding flash flooding and even landslides. That is why it is important to be aware of the rainfall rate when severe weather is expected.
The rainfall rate is not the same as the rainfall total. The rainfall total is the amount of rainfall that has accumulated over a period of time usually 24 hours. The rainfall rate is a measure of the intensity of the rainfall.
There are different types of rain gauges that are used to measure the rainfall rate. The most common type is the tipping bucket rain gauge. As rainfall falls into the gauge it tips a bucket that is attached to a turning wheel. The wheel is connected to a mechanical or electronic recorder.
The amount of rainfall is determined by the number of times the bucket tips in a certain period of time. The rainfall rate is usually calculated in inches per hour.
Some rain gauges can measure the intensity of the rainfall as well as the total amount. These gauges are called intensity-duration-frequency (IDF) gauges.
IDF gauges are important for determining the rainfall rates for designing flood control structures such as dams and levees.
There are also automated rain gauges that are used in weather stations. These gauges use sensors to measure the rainfall. The data from the gauges is sent to a central computer that calculates the rainfall rate.
Rainfall rates can also be estimated by weather radar. Radar works by bouncing electromagnetic waves off of raindrops. The amount of rainfall can be estimated by the reflectivity of the raindrops.
Rainfall rates can vary greatly depending on the type of precipitation. A rain shower may have a rainfall rate of 2 inches per hour. A thunderstorm may have a rainfall rate of 5 inches per hour. A tropical storm can have a rainfall rate of 10 inches per hour or more.
When severe weather is expected it is important to be aware of the rainfall rates that may occur. Heavy rainfall can cause flooding flash flooding and even landslides.
