उत्तर
Cyclones are low-pressure areas that occur over warm ocean waters of temperate and tropical regions. Seen as swirling atmospheric disturbances they are accompanied by heavy rain, huge waves and powerful winds blowing at a velocity of 300 km per hour. Storm surges during the high tide, called storm tides, cause enormous damage to coastal regions.
