Sudden Deluge

  • Ramban, J&K Recent Event: Ramban district experienced heavy rainfall and hail, causing significant damage.
  • Rainfall Surge: IMD recorded a 575% increase in rainfall (16.9 mm) compared to the normal (2.5 mm) in 24 hours.
  • Cloudburst Definition: A cloudburst is defined as 10 cm or more of rainfall in one hour over a 10 km x 10 km area, or 5 cm in 30 minutes over the same area.
  • Orographic Lift: Cloudbursts are frequent in mountainous regions due to orographic lift, where warm, moist air 48.3 47.8C117.2 448 288 448 288 448s170.8 0 213.4-11.5c23.5-6.3 42-24.2 48.3-47.8 11.4-42.9 11.4-132.3 11.4-132.3s0-89.4-11.4-132.3zm-317.5 213.5V175.2l142.7 81.2-142.7 81.2z"/> Subscribe on YouTube
rises, cools, and releases precipitation.
  • Flash Floods: Sudden inundation from excessive rainwater overwhelming drainage systems, common in hills due to poor water absorption by rocky terrain. Flash floods are often deadly.
  • Landslides: Movement of rock/debris down a slope when gravity exceeds resistance. Heavy rain increases weight and reduces cohesion, increasing landslide risk. Can cause fatalities, disrupt transportation and block rivers.
  • Forecasting Challenges: Cloudbursts are difficult to forecast due to their localized nature.
  • Cloudburst Causes sudden condensation of moisture-laden clouds, enhanced by topography.
