Geography
Uneven monsoon with below average rainfall in June, above average rainfall in July and a dry August was reported one year. How does this pattern of rainfall differ from the regular pattern of rainfall over the subcontinent.
Answer
This pattern of rainfall is different from the regular monsoon pattern in India. Normally, the Southwest monsoon sets in by early June and brings steady rainfall through June to September. Rainfall is usually well-distributed during these months.
However, in the year mentioned, rainfall was below average in June, unusually high in July, and almost dry in August. This uneven distribution can affect agriculture and water availability, as crops need regular and timely rain.
The difference is highlighted in the table below:
| Month | Normal Monsoon Pattern | Observed Pattern (One Year) |
|---|---|---|
| June | Steady onset with moderate rainfall | Below average rainfall |
| July | Heavy and consistent rainfall | Above average rainfall |
| August | Continued rainfall, slightly reduced | Very little or no rainfall (dry month) |
