Q. Which of the following statements about ‘cloudburst’ is not correct?
Answer:
It is associated with cirrostratus clouds.
Notes:
- A cloudburst refers to an extreme amount of rain that happens in a short period, sometimes accompanied by hail and thunder, and this has a precise definition.
- The India Meteorological Department (IMD) defines it as unexpected precipitation exceeding 100mm (or 10 cm) per hour over a geographical region of approximately 20 to 30 square km
- A cloudburst occurs when moisture-carrying air moves up a hilly terrain, forming a vertical column of clouds known as ‘cumulonimbus’ clouds.
- Such clouds usually cause rain, thunder and lightning. This upward motion of the clouds is known as an ‘orographic lift’.
