Cloudbursts in India
The India Meteorological Department (IMD) rejected reports that Assam and Nagaland had experienced cloudbursts, clarifying that the Upper Assam floods were caused by prolonged heavy rainfall rather than a cloudburst.
- Cloudburst: According to the IMD, a cloudburst is an extreme localized rainfall event in which 10 cm (100 mm) or more rainfall occurs within one hour…
- The rainfall is so intense that the ground cannot absorb it, resulting in flash floods, landslides, and debris flows.
- Some scientists have proposed a "mini-cloudburst" category for 5 cm rainfall in one hour
- Mechanism of Formation: Cloudbursts are driven by intense convective precipitation and the rapid formation of cumulonimbus clouds (which can extend…
Show 6 more facts
- Strong Updrafts: As the air rises and cools, condensation occurs
- The 'Burst': When the weight of the accumulated water droplets finally overcomes the lifting force of the updraft
- Primary Hotspots: The Himalayan states (Uttarakhand, Himachal Pradesh, Jammu & Kashmir) and the Northeast
- Hyper-localized Events: Cloudbursts occur over just 20–30 sq
- Rapid Development: They form and intensify within a few hours, leaving minimal lead time for warnings.
- Radar Blind Spots: Mountainous terrain obstructs Doppler Weather Radar beams, limiting observation in cloudburst-prone regions.

Cloudburst, Landslide, and Flash Flood
Torrential rain in Ramban tehsil of Jammu and Kashmir has caused casualties, significant infrastructure damage, and forced emergency relocations.

- Orographic Lifting: It occurs when moist air is forced to rise over a mountain range
- Definition: A landslide is the downward movement of rock, soil, or debris on a slope due to gravity
Show 6 more facts
- Causes: Natural factors like heavy rainfall, earthquakes, and water seepage weaken slopes, while human activities such as deforestation and…
- Landslide Prone Areas: In India, 0.42 million sq
- Examples: In 2024, Wayanad (Kerala) faced significant landslides, while the 2013 Kedarnath (Uttarakhand) landslide caused over 5,700 deaths
- Definition: Flash floods are sudden increases in water levels during or immediately after intense rainfall
- Causes: Flash floods are primarily caused by intense rainfall that overwhelms the soil's absorption capacity and drainage systems
- Additionally, urbanisation with impervious surfaces like roads and buildings increase runoff, reducing water absorption and intensifying flood risks.

Forest Fires
Recently, Forest Fires have been raging in the Coonoor forest range in the Nilgiris in Tamil Nadu.
- The Indian Air Force joined the ongoing firefighting efforts of the state forest department
- The Bambi Bucket is especially helpful in fighting wildfires that are difficult or impossible to reach from the ground
- About: Also called bush or vegetation fire or wildfire
- A wildfire requires three essential elements to sustain combustion like Fuel, Oxygen, and a Heat source.
Show 6 more facts
- Surface Fire: A forest fire may burn primarily as a surface fire
- Underground Fire/Zombie Fire: The fires of low intensity
- This fire spreads very slowly and in most cases it becomes very hard to detect and control such types of fires.
- They may continue to burn for months and destroy the vegetative cover of the soil.
- These controlled burns are carefully planned and executed under specific conditions to minimize risks and maximize benefits to the forest ecosystem.
- National Action Plan for Forest Fires (NAPFF)
