What is Tropical Cyclone ? A gigantic mass of revolving moist air A storm system - Low pressure centre - Numerous thunderstorms

- area of low atmospheric pressure near the Earth’s surface - Driven by the release of large amounts of latent heat of condensation Moist air Heat is released + Water Vapour in the air condenses Fig.1

Heat - distributed vertically around the centre of the storm The environment inside the cyclone is warmer Warmer

The structure of tropical cyclone divided into - Rain bands - Eye

Rain bands: - Bands of showers and thunderstorms - Spiral cyclonically toward the centre - Tornadoes often form in them Eye: - The centre of a tropical cyclone - An area of sinking area - Circular in shape

Tropical Cyclones Cyclone Nargis - Category 4 cyclone - a strong Tropical Cyclones (caused the deadliest natural disaster)

Many areas suffered 1) Yangon 2) Pegu 3) Mon 4) Ayeyarwady

- Occurred on 3rd May , 2008 Cyclone Nargis

How was the Cyclone Nargis formed?

developed on April 27 in the central area of Bay of Bengal tracked slowly northwestward quickly strengthened dry air weakened the cyclone on April 29 intensified to attain peak winds of at least 165 km/h (105 mph) on May 2 beginning a steady eastward motion

assessed peak winds of 215 km/h (135 mph) moved ashore in the Ayeyarwady Division of Burma near peak intensity after passing near the major city of Rangoon the storm gradually weakened until dissipating near the border of Burma and Thailand

Cyclone Nargis impact 'bigger than tsunami'

Effects flooding food shortage felled trees homeless landslides blocked roads economic loss deaths & casualties

Monks wade through floodwaters in Rangoon Fishing boats in Rangoon harbor destroyed by the storm Flooding

Cyclone Nargis Floods Burma Before After

Damages At least 134,000 people (dead or missing) Estimate total number severely affected:2.4 million people $10 billion loss Basic infrastructures (e.g. buildings, hospitals) were destroyed

Residents line up to get rice after cyclone Nargis hit the town of Phyar Pon Famine The influence of the cyclone lowered temperatures along the Indian coastline

How should the world respond to Burma? intensify international economic and poltical pressure on junta leaders Provide aid Donate money Help with the recover work Supply resources
