  1. Remote Sensing Imagery of Cyclone Gonu and Areas Affected

  2. History of Tropical Cyclones in the North Indian Ocean (1984-2013)

  3. 1984-2005

  4. Storms in 2007

  5. Cyclone Gonu • Strongest tropical cyclone to hit the Arabian Peninsula during last decade • First observed as tropical depression in the Indian Ocean on May 27 by weather satellites • Affected the eastern parts of Oman on June 4, 2007 • Gonu peaked to category 5 on June 6 • Brought along strong and torrential rains, high waves, and strong winds • As the storm weakened, it moved through the Arabian Sea and made a landfall in Iran on at 0.00 GMT on June 7, 2007 • Gonu was downgraded to category 1 by June 8, 2007

  7. Cyclone Gonu • Gonu dropped heavy rainfall near the eastern coastline, reaching up to 610 mm (24 inches) which caused flooding and heavy damage. • The cyclone caused about $4 billion in damage (2007 USD) and 49 deaths in Oman, where the cyclone was considered the nation's worst natural disaster. • In Iran, the cyclone caused 23 deaths and $215 million in damage (2007 USD).

  8. Monitoring and early warning

  9. Monitoring of Tropical Cyclones Using MSG • IR10.8 to get info on cloud top temperature/height • HRVIS to see detailed structures • NIR1.6 and IR3.9 (solar component) to get information on phase and particle size • IR3.9 - IR10.8 to find areas with most intense development/precipitation • RGB 01/03/09 (Day) or RGB 01/04/09 (Day) and RGB 10-09/09-04/09 (Night) to monitor cloud types and convective development • RGB 05-06/04-09/03-01 to monitor convective development

  10. Evaluation of damaged area

  13. Remote Sensing Satellites • Satellites are major contributors to weather and climate studies • Meteorological and environmental satellites provide techniques for operational monitoring of the phenomenon on a continuous basis • Imagery provided by European Meteorological Satellites (EUMETSAT) are key input in all early warning systems of Tropical Cyclone

  14. Remote Sensing Techniques • During natural disasters, accessibility and other infrastructure may not be in place to acquire valuable information from affected sites • Medium to high-resolution imagery necessary for mapping and evaluation of major disasters • Cyclone Gonu is example of the usefulness of satellites to monitor, forecast and to study this damaging phenomenon
