Cyclone - Drishti IAS The government should consider the NDMA Guidelines for the management of cyclones: With the adverse Climate Change risks posted by IPCC reports the only option for India is to better preparedness for the disaster with better urban planning, community awareness, etc. At high altitudes, the descending air is hot and dry. Rapid heating of the landmasses during the spring and early summer exaggerates the passage of the seasonal cycle in these areas. Occasionally during strong tropical storms the rainbands form their own strong thunderstorms. This scale estimates potential property damage. Wind speed then determines whether a thunderstorm develops into a depression, storm or cyclone. When those wind speeds reach between 25 and 39 miles per hour, tropical or cyclone depressions form. Cyclone in Maharashtra is a system with low pressure that develops over warm oceans. This deep cloud often forms an almost circular ring called the eyewall around the very centre of the storm which is itself free from clouds. It particularly effectedChennai inTamil Nadu andAndhra Pradeshfurther up the coast. Accessibility
