What Is a Cyclone?
Cyclones are huge revolving storms caused by winds blowing around a central area of low atmospheric pressure. In the northern hemisphere, cyclones, called hurricanes or typhoons, blow in an anti-clockwise direction. In the southern hemisphere, these tropical storms are known as cyclones, whose winds blow in a clockwise direction.
Cyclones develop over warm seas near the Equator. Air heated by the sun rises very swiftly creating areas of very low pressure. As the warm air rises, its moisture condenses into massive thunderclouds. Cool air rushes in to fill the void that is left, but because of the constant turning of the Earth on its axis, the air is bent inwards and then spirals upwards with great force. The swirling winds rotate faster and faster, forming a huge circle which can be up to 2, 000 km across. At the centre of the storm is a calm, cloudless area called the eye, with no rain, and fairly light winds. As the cyclone builds up it begins to move, and is sustained by a steady flow of warm, moist air. The strongest winds and heaviest rains are found in the towering clouds which merge into a wall about 20-30 km from the storm’s centre. Winds around the eye can reach speeds of up to 200 km/h, and a fully developed cyclone pumps out about two million tons of air per second. This results in more rain being released.
Cyclones are dangerous for people living around tropical areas. The most destructive force of a cyclone is the fierce winds. These winds are strong enough to topple fences, sheds, trees, power poles and caravans easily. A cyclone typically churns up the sea, causing giant waves and surges of water known as storm surges which rush inland with deadly power, flooding low-lying coastal areas.
Fill in each blank in no more than three words according to the passage.
