It is ideal to have at least 30 years’ worth of data for calculation of the normal period.; Data used: N/A; Data format: N/A; Data access: N/A; Concise description: Simple calculation that can be used to compare any time period for any location. Can be computed on daily, weekly, monthly, seasonal and annual timescales, which will suit many users needs. Calculated by dividing actual precipitation by normal precipitation for the time being considered and multiplying by 100.

Van Nostrand’s Scientific Encyclopedia John Wiley and Sons, Inc., doi: 10.1002/0471743984.vse8593. A popular method that is quick and easy to calculate with basic mathematics. Establishing the normal for an area is a calculation that some users could confuse with mean or average precipitation. It is hard to compare different climate regimes with each other, especially those with defined wet and dry seasons. N/A
