Hurricanes
Hurricanes are gigantic tropical storms that can be hundreds of kilometers wide. They bring along very strong winds and a lot of rainfall. They often cause flooding near the coasts and sea levels rise.
1. __________________________
Hurricanes are born over tropical oceans, usually during late summer and early autumn. They need two things to get them started: heat and moist air. During the summer the ocean surface heats up and warm moist air starts to rise. Cool air sinks down to replace it. This creates an area of low pressure. The rotation of the earth creates winds around the center of such a low-pressure area. In the northern hemisphere the air moves counter clockwise, in the southern part clockwise. Such a system is called a cyclone. When warm air rises, it cools and creates clouds. Soon, thunderstorms form and it starts to rain.
All hurricanes begin as cyclones but not all cyclones become storms or hurricanes. Some die out a few days after they start. They don’t have enough energy to become a hurricane. When winds are stronger than 119 km an hour a storm officially becomes a hurricane.
2. __________________________
The center of a hurricane is called the eye, a calm area with little rainfall. It is about 30 to 50 km wide. Inside the eye the sea can rise up to one meter because the air moves up. The eye wall is around the eye. This is an area of thunderstorms, rain and the strongest winds—up to 300 km an hour. Then come long bands of rain clouds that are curved towards the center of the hurricane.
3. __________________________
In the northern hemisphere hurricanes normally move in a westward direction and then they turn north and northeast. Their path takes them away from the warm tropical water of the equator. When hurricanes move over colder water or over land they lose a lot of their energy. They slow down and as time goes on, they disappear. In the southern hemisphere their path leads them to the south and southeast.
4. __________________________
When a tropical storm forms over the Caribbean Sea it gets a name. Every year the first storm of the season is given a name that starts with the letter A, the second storm gets a name starting with B and so on. Years ago only women’ s names were used for tropical storms. Today male and female names alternate –for example, the first storm is named Alexandra, the second one Billy, then Catherine etc. Each year new names are used so that you can connect a storm to a certain year.
5. __________________________
Hurricanes are causing more and more damage throughout the Gulf Region, mainly because the population is constantly growing. Many things can be done to protect yourself and your property during a hurricane: Keep emergency supplies of food and water; keep a battery-powered radio ready in case the power goes out. Listen to the instructions you get; keep the gas tank of your car full, in case you have to leave quickly; protect your house by nailing plywood over the windows and doors. Tie down loose objects; find out which roads are best to take you away from the storm; leave your house as soon as you are ordered to evacuate, etc.

  LONDON ( Reuters)— Eco tourism ( 生态旅游) is causing A.lot of damage to wildlife and may be endangering the survival(生存) of the very animals people are flocking to see, according to researchers.

  Biologists and conservationists ( 自然环境保护论者) are worried because polar bears, dolphins, penguins and other creatures are getting stressed and losing weight and some are dying.

  "Evidence is growing that many animals do not react well to tourists in their backyard,” New Scientist magazine said.

  The immediate effects researchers have noticed are changes in behavior, heart rates, or stress hormone levels but they fear it could get much worse and over the long term "could endanger the survival of the very wildlife they want to see".

  Although money produced through ecotourism, which has been growing at about 10—30 percent A.year, has major benefits for poor countries and people living in rural areas, the Swiss-based World Conservation Union and some governments fear not all projects are audited (审计) and based on environmentally friendly policies, according to the magazine,

  "The transmission(传播) of disease to wildlife, or small changes to wildlife health through disturbance of daily life or increased stress levels, while not obvious to the casual observer, may translate to lower survival and breeding ,"said Philip Seddon, of the University of Ota go in Dunedin, New Zealand.

  Scientists have noticed that bottleneck dolphins along the northeastern coast of New Zealand become nervously excited when tourist boats arrive. Similar changes in behavior have been observed in polar bears and yellow-eyed penguins in areas visited by eco tourists are producing smaller babies.

  Conservationists are now calling for more research into the effect of eco tourism on animals and say the industry must be developed carefully. They also want studies done before new eco tourism projects are started.

  “The animals’ welfare should be very important because without them there will be no eco tourism,” said Rochelle Constantine of the University of Auckland in New Zealand.
