The weather is very important in the life of people. Every morning we look out of windows to see what the weather is like. It can be sunny, windy, cloudy, foggy, rainy.
However sometimes we have a type of extreme weather, or natural disasters, for example, hurricane, tornado, lightning, hailstorm, earthquake. Many of them can damage or destroy buildings, roads, can kill people and animals.
For example, Hurricane Katrina…
When Katrina occurred, over 80% of the city was under water. Hurricane Katrina was one of the most powerful storms that has ever hit the Atlantic coast with winds of over 270km per hour. As it became stronger over the Gulf of Mexico, the mayor of New Orleans declared a state of emergency and started evacuating the city. As the hurricane came ashore, it brought an 800-metre-high storm surge that rod the rivers up to New Orleans, and smashed through the levees. Almost 1500 people had lost their lives, because of Hurricane Katrina.
A tsunami is a large wave that travels at great speed towards land. They are usually caused by an undersea earthquake, but they can also happen after a large undersea landslide and an underwater volcanic eruption. When undersea earthquake happens, the Earth’s tectonic plates move suddenly downward and upwards. The water forms a wave. Just like when you throw a pebble into a lake, the water is very powerful force and can cause tremendous damage.
Nowadays more and more changes are taking place in the world’s climate. Because of global warming the weather is becoming more extreme. Hurricanes, tornadoes, earthquakes, tsunamis are becoming more violent and severe.
