Explanation:

Cloudbursts are short-duration, intense rainfall events over a small area.

• It is a weather phenomenon with unexpected precipitation exceeding 100mm/h over a geographical region of approximately 20-30 square km.
• In the Indian Subcontinent, it generally occurs when a monsoon cloud drifts northwards, from the Bay of Bengal or the Arabian Sea across the plains then on to the Himalaya that sometimes brings 75 millimetres of rain per hour. 

Occurrence of cloudbursts

• The relative humidity and cloud cover is at the maximum level with low temperature and slow winds because of which a high amount of clouds may get condensed at a very rapid rate and result in a cloudburst. Hence, statement 1 is correct.
• As temperatures increase, the atmosphere can hold more and more moisture and this moisture comes down as a short very intense rainfall for a short duration probably half an hour or one hour resulting in flash floods in the mountainous areas and urban floods in the cities.

Cloudburst are Different from Rainfall

• Rain is condensed water falling from a cloud while cloudburst is a sudden heavy rainstorm.
• Rain over 100mm per hour is categorised as a cloudburst.

Hence both statements are correct.
