Storms in 2007
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

Cyclone GonuCyclone 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).

• 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

Remote Sensing SatellitesRemote 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
Remote Sensing TechniquesRemote 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
