Extreme Weather Event: Tropical Cyclones in Bangladesh

Extracts from this document...

Introduction

Extreme Weather Event: Tropical Cyclones in Bangladesh Introduction: In this report I will investigate the problems of tropical cyclones, and I will concentrate on the country of Bangladesh. I am using Bangladesh as the country for my report because it is a perfect example of what a tropical cyclone is capable of on flat land. What are tropical cyclones? A tropical cyclone is a very violent storm which is produced over warm tropical oceans which have a temperature of 270C. Below is a picture of how tropical cyclones develop. The oceans temperature is about 270C, and the arrows show that the intense heat is rising upwards. The clouds then start to form low pressure. They are like stronger versions of mid-latitude depressions. They are areas of very intense low pressure which are rotated by strong winds, cloud and heavy rain. The wind speeds can sometimes reach up to 150 km per hour. ...read more.

The storm reached its peak at around midnight. The cyclone also brought a huge tidal wave which measured 6.4metres high. Below, is a picture of how the tidal wave occurred. The red arrow shows strong the winds approaching the Bangladesh coastline, and the black arrow shows the air pressure rising. So as the air pressure rises, so does the sea level. Along with this, the fierce winds are driving the water forward forcing a huge wave to form. How the people tried to survive? When the people of Bangladesh found out that there was a tropical cyclone heading there way, most of them just waited until the tropical cyclone was close to the coast. As the cyclone approached, the people then rushed to the cyclone shelter for safety. As midnight drew close, a quarter of the population of Bangladesh had to stand in the shelter and wait until the storm was over. ...read more.

Conclusion

Although tropical cyclones cannot be prevented, they can be managed by people. Here are some ways in which they can do this: * The people of Bangladesh could practice drills on what to do if a cyclone occurred. * Grow mangrove trees to stabilise the water banks. * Save money on building schools etc. by using the cyclone shelters. And they could use the money that they save to build more cyclone shelters. * Make more embankments to stop the water levels from flooding Bangladesh. * Houses could be reinforced to decrease the chances of them being destroyed. Conclusion: I have now finally come to the conclusion that, despite a lot of options on how to manage tropical cyclones, the only valid conclusion is, that people could be persuaded to donate money to Bangladesh to build more cyclone shelters and reinforce a lot of the buildings. I had come to this conclusion after researching on many of the manageable options. ?? ?? ?? ?? Jagbinder Singh Dhillon Geography 1 ...read more.

  1. In the experiment mimicking extratropical cyclones, how does the apparatus represent the atmosphere of ...

    This was done via the convection of heat; heat was transferred through the representational atmosphere (room-temperature water) from the outer warm wall to the inner cold wall. This process was aided and made efficient by the meandering flows of the jet streams which formed vortices like movements.

  2. Atmospheric Processes - Depressions

    How such a low pressure system developed on this particular occasion is argued over, however one theory is that it may have been a result of the jet stream in the wake of the 1987 hurricane Floyd, coinciding with exceptionally warm weather from the Bay of Biscay.

    c) In 1981, the emissions of nitrogen oxides (NOx) were low in sources such as domestic, commercial/public, refineries, other industry, shipping and other transport. Power stations and road transport were emitting nearly 1,000 tonnes. At that time, cars and roads had rapidly improved and developed for the growing population.

    These easterly trade winds result in a 60cm (Wikipedia, 2005) increase in water height in the western Pacific and there is an even more marked increase in warm below the surface where the thermocline can reach depths of inexcess of 200m (Barley and Chorley, 1998).

    In south-east England, where the greatest damage occurred, gusts of 70 knots or more were recorded continually for three or four consecutive hours. During this time, the wind veered from southerly to south-westerly. To the north-west of this region, there were two maxima in gust speeds, separated by a period of lower wind speeds.

    I think that the image of rain is also used for moods within the story. The way that a minute later Mr. Davidson comes to tell the other members of the party that they are stuck on the island, is placed well; because the image of the rain is depressive
