What is the annual rainfall for station X?
Answer Details
Annual rainfall is the total amount of rainfall received at a station over the course of a full year. To find it, add up the monthly rainfall figures for all twelve months provided in the climate data table for station X.
The monthly rainfall values (in mm) from the table are:
| Month | Jan | Feb | Mar | Apr | May | Jun | Jul | Aug | Sep | Oct | Nov | Dec |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Rainfall (mm) | 62 | 50 | 56 | 89 | 180 | 189 | 140 | 163 | 228 | 230 | 83 | 41 |
Summing these values step by step:
\[ 62 + 50 + 56 + 89 + 180 + 189 + 140 + 163 + 228 + 230 + 83 + 41 = 1511 \text{ mm} \]
The annual rainfall for station X is therefore 1511 mm.
Common errors on this type of question include accidentally skipping a month when adding (which would give a lower total) or misreading a value from the table. Always count to confirm you have included all twelve months before finalising your sum.
