Explanation:

During the south-west monsoon period after having rains for a few days, if rain fails to occur for one or more weeks, it is known as break in the monsoon. These dry spells are quite
common during the rainy season. These breaks in the different regions are due to different reasons:
Statement 1 is correct (i) In northern India rains are likely to fail if the rain-bearing storms are not very frequent along the monsoon trough or the ITCZ over this region. It also occurs if the ITCZ shifts northward over the foothills of Himalayas and causes heavy rainfall along the foothills of himalayas. This northward shift of the ITCZ creates a high pressure over the plains and thus the South West monsoon winds are not able to flow. Statement 2 is correct (ii) Over the west coast the dry spells are associated with days when winds blow parallel to the coast. This fails to produce an orographic effect and thus leads to a break in monsoon. Such breaks are likely to occur in the month of August.
