A cloudburst is an unusually intense and very short-duration rainfall event over a small area. In the Indian context, meteorologists often define it as more than 100 mm of rain in one hour over an area of roughly 30 km² or less. The mechanism involves warm, moisture-laden air that is forced upward (often by steep terrain), cools rapidly, forms deep cumulonimbus clouds, and then “bursts” when it can no longer hold the condensed water — releasing an enormous downpour in a brief span. In mountainous regions this sudden deluge can trigger instant runoff, flash floods and landslides — because the steep slopes and narrow valleys accelerate water and debris flow.
How these occur?Moisture accumulation: Moist air (often from monsoon winds) travels toward a mountain or hilly region. As it meets terrain, it is forced to rise (orographic lift), cools, and condensation begins. Mongabay-India+1Cloud build-up: The rising air forms deep towering clouds (cumulonimbus)... Read More
Despite forecasts of light rainfall, Delhi continues to struggle with toxic air as pollution levels remain alarmingly high. On Monday, the national capital recorded a minimum temperature of 17.3°C — slightly above the seasonal average — with humidity levels touching 94% by morning. The skies stayed partly cloudy with a possibility of light rain later in the evening, but even that offered little respite from the worsening smog.
According to data from the Central Pollution Control Board (CPCB), pollution hotspots such as Bawana and Anand Vihar reported extremely high Air Quality Index (AQI) levels of 401 and 431, respectively. Out of 38 monitoring stations across the city, 23 recorded AQI values above 300, placing them in the “very poor” category.
