    What is an average annual rainfall?

    The rainfall averages are based on the daily rainfall measurements. Daily rainfall is defined as the 24-hour accumulated amount of rain from 8:00 AM on a given day until 8:00 AM the following day. The average rainfall for a specific month is the average of 30 monthly values for the period 1981-2010.

    How is the rainfall calculated?

    The standard instrument for the measurement of rainfall is the 203mm (8 inch) rain gauge. This is essentially a circular funnel with a diameter of 203mm which collects the rain into a graduated and calibrated cylinder. The measuring cylinder can record up to 25mm of precipitation.

    What is the average of rainfall?

    In meteorology, precipitation is any product of the condensation of atmospheric water vapor that falls under gravity. The main forms of precipitation include drizzle, rain, sleet, snow, graupel and hail. This process is typically active when freezing rain occurs.

    How do you calculate rainfall?

    Here’s what you’ll need to do:

  • Measure the diameter of the bucket at the level of the rain.
  • Measure the diameter of the bucket at the bottom in the same way.
  • Calculate the average of the two diameters.
  • Divide by two to find the average radius.
  • Find the average volume of rain = Depth x radius x radius x 3.14.
