METEOROLOGY – PRECIPITATION CALCULATOR
Rainfall Intensity
A precise tool.
What is the Rainfall Intensity & How does it work?
Rainfall intensity is a measure of the rate at which rain falls, typically expressed in millimeters per hour (mm/hr). It is an important parameter in meteorology as it helps to assess the severity and potential impacts of rainfall events.
The classification of rainfall intensity can help in understanding the type of precipitation event. For instance, light rain usually has an intensity of less than 2.5 mm/hr, moderate rain ranges from 2.5 to 7.6 mm/hr, and heavy rain exceeds 7.6 mm/hr.
I = frac{P}{t}
I = Rainfall intensity (mm/hr), P = Amount of precipitation (mm), t = Time duration (hr)

Frequently Asked Questions
What is considered light rain in terms of intensity?
Light rain has an intensity of less than 2.5 mm/hr.
How do you classify moderate rain based on intensity?
Moderate rain ranges from 2.5 to 7.6 mm/hr in terms of intensity.
What is the threshold for heavy rain in rainfall intensity?
Heavy rain exceeds an intensity of 7.6 mm/hr.
How can I calculate rainfall intensity if I know the total rainfall and duration?
Divide the total rainfall (in millimeters) by the duration (in hours) to get the intensity in mm/hr.
Why is understanding rainfall intensity important in meteorology?
Understanding rainfall intensity helps assess the severity of precipitation events and their potential impacts on the environment and infrastructure.
Can you provide an example of how to calculate rainfall intensity?
If 10 mm of rain falls in 2 hours, the intensity is 10 mm / 2 hr = 5 mm/hr.
What are some practical applications of knowing rainfall intensity?
Knowing rainfall intensity helps in planning for drainage systems, flood risk assessments, and agricultural water management.
