Explanation: Cloudbursting is a meteorological phenomenon characterized by a sudden and extremely heavy rainfall over a small area. This type of event is often associated with flash floods and landslides due to the rapid accumulation of water in a short period. Cloudbursts typically occur when a large amount of moisture is present in the atmosphere and is rapidly condensed into precipitation due to factors such as orographic lifting (when moist air is forced to rise over mountains) or intense convective activity.
On 26th July 2005, Mumbai experienced one of the most severe cloudbursts in its history. The city and its suburbs were inundated with an unprecedented amount of rainfall, leading to widespread flooding and significant damage to infrastructure. The rainfall was so intense that it broke the previous record for the highest rainfall in a single day, which was set in 1974. The event was a result of a combination of factors, including the monsoon season, the geographical location of Mumbai, and the presence of a low-pressure system that intensified the rainfall.
Understanding cloudbursting is crucial for disaster management and urban planning, especially in regions prone to such events. It highlights the importance of having robust drainage systems and emergency response plans in place to mitigate the impact of such natural disasters. The 2005 Mumbai floods serve as a case study for the potential consequences of cloudbursts and the need for improved urban resilience.
In contrast, the other options provided do not accurately describe the event. A tsunami is a series of ocean waves caused by underwater disturbances, which is not relevant to the rainfall event in Mumbai. Snowfall is a winter phenomenon involving the accumulation of snow, which is not applicable to Mumbai's tropical climate. A dry famine refers to a period of drought and food shortage, which is the opposite of what occurred during the 2005 event.
Thus, the correct answer is cloudbursting, as it accurately describes the sudden and heavy rainfall that caused the 2005 Mumbai floods.
