Explanation: Characteristics of Monsoonal Rainfall

  1. Rainfall received from the southwest monsoons is seasonal in character, which occurs between June and September.
  2. Monsoonal rainfall is largely governed by relief or topography. For instance, the windward side of the Western Ghats registers a rainfall of over 250 cm. Again, the heavy rainfall in the north-eastern states can be attributed to their hill ranges and the Eastern Himalayas
  3. The monsoon rainfall has a declining trend with increasing distance from the sea. Kolkata receives 119 cm during the southwest monsoon period, Patna 105 cm, Allahabad 76 cm and Delhi 56 cm.
  4. The monsoon rains occur in wet spells of few days’ duration at a time. The wet spells are interspersed with rainless intervals known as breaks. These breaks in rainfall are related to the cyclonic depressions mainly formed at the head of the Bay of Bengal, and their crossing into the mainland. Besides the frequency and intensity of these depressions, the passage followed by them determines the spatial distribution of rainfall.
  5. The summer rainfall comes in a heavy downpour leading to considerable run off and soil erosion.
