Read the passage and answer the questions that follow.
Tropical storms are huge areas of weather disturbances that develop in the oceans of the world. They gather heat and energy from the warm ocean water, or currents, and can grow to sizes of up to 600 miles across and generate swirling winds with speeds of 75 to 200 miles per hour! Although all large tropical storms are more or less the same, they are called by different names depending on their location. In the Atlantic and the Northeast Pacific oceans (for example, near the United States), they are called "hurricanes".
However, for the same type of disturbance in the Northwest Pacific Ocean (for example, near Japan, which is regularly hit by them every year), the term "typhoon" is used, while those that occur in the South Pacific and Indian Ocean are known as "cyclones". In order to be classified as one of these, a tropical storm must have wind speeds of 74 miles per hour. Big tropical storms are actually given names which are chosen from a list that is created every year. In the United States, for example, the first hurricane name starts with the letter 'A', like Alexander, and the names move through the alphabet as more hurricanes appear.
Tropical storm clouds move in a circle around a point called the eye, which is the centre of the storm. When a large tropical storm comes ashore, it brings with it heavy rains and powerful winds that can damage, or even destroy, buildings, cars and trees. However, the most devastating element of a large tropical storm is the storm surge. These are large waves that are generated by the storm and can cause massive flooding and are the main reason people in coastal cities are ordered to evacuate and move to higher ground when a large storm approaches. Scientists who study the weather are called meteorologists and they monitor these storms carefully so that they can determine their speed and where they are heading. In the United States, hurricane season begins on 1 June and lasts until 30 November. In terms of frequency and damage caused, 2005 was a record year for hurricanes.
