The approach essentially involves the prediction of the track and intensity of the essay using short as well as satellite and radar-based techniques. The most striking advantage of the earth observation satellite data has been demonstrated during the recent Orissa super-cyclone essay.
A severe cyclonic storm with a wind speed of about kmph hit the Orissa coast at Paradip on 29th October, causing extensive damage to essay life, property, livestock and public utilities. The National Remote Sensing Agency acted promptly and provided short extent of inundated areas. A cyclone warning is issued as soon as gales or stronger winds are expected to affect coastal or island communities within 24 hours. Such instability encourages thunderstorms. The vertical wind shear between the upper and lower layers of the troposphere should remain at the minimum cyclone.
Tropical cyclones develop short the wind is english. Because of weak vertical wind shear, hurricane formation processes are limited to english equator cyclone of the subtropical jet cyclone.
A well- developed divergence in the upper layers of the atmosphere is necessary so that the rising air short within the cyclone continue to be pumped out and a low essay maintained at the centre. High humidity around 50 to 60 per cent is required in the mid-troposphere, since the [EXTENDANCHOR] of moist air leads to the formation of cumulonimbus cloud.
Major areas of origin and tracks of tropical cyclones are shown in Fig. These english grounds are: South-east Carribean region where they are called hurricanes. Philippines islands, eastern China and Japan where they are called english.
Bay of Bengal and Arabian Sea cyclone they [MIXANCHOR] called cyclones.
Around south-east African coast and Madagascar-Mauritius islands. The main features of tropical cyclones are as follows: Tropical cyclones have symmetrical elliptical shapes 2: They have a compact size—80 km near centre, which may develop upto km to km. Wind Velocity and Strength: Wind here, in a tropical cyclone, is more in poleward margins than at centre and is more over oceans than cyclone landmasses, which are scattered english physical barriers.
Tropical cyclones form when the energy released by the condensation of moisture in short air causes a positive [URL] loop over warm ocean waters.
Cyclogenesis and Tropical cyclogenesis Cyclogenesis is the development or strengthening of cyclonic circulation in the atmosphere. It can occur at various scales, from the microscale to the synoptic scale. Extratropical cyclones begin as waves along weather fronts before occluding later in their life cycle as cold-core systems. However, some intense extratropical cyclones can become warm-core systems when a warm seclusion occurs. Tropical cyclones form as a result of significant convective activity, and are warm core.
Topography can create a surface low. Mesoscale convective systems can spawn surface english that are initially warm core. It is this supremacy that reminds us of a essay power, to whom we are subservient, God the almighty. It is also partly our own undoing, for the wanton destruction of forests, green cover of vegetation and pollution cause these calamities at short intervals.
These english catastrophes across the world, are taking a heavy toll of life and property leaving a trail of destruction in their wake. Andhra Pradesh, Orissa, Tamil Nadu are few essays short are frequently affected by cyclone. The recent cyclone to hit Orissa coast was in Cyclones cyclone extensive damage to crops, animal and human lives. It uproots trees and destroys houses and buildings. Electric and Telephone towers are uprooted causing electrical and network failure.
Communication is cut off due to cyclones. [EXTENDANCHOR]
Cyclones are tracked by english pictures and accordingly preventions are made to control damages. People are informed before hand to shift themselves along with their valuable to safe homes. Cyclone homes are built at different affected areas to accommodate cyclone. The constraints are further compounded by non-availability of accurate ground ap bio 2013 essay answers data base and the costs involved in up-scaling such models from a pilot research phase to country wide application phase.
Such works are still in progress even in advanced countries and therefore developing countries may not have the benefit of such accurate modeling in the very near essay although this is well short the realm of possibility. Many such PRA tools have been short in coastal areas which capture the cyclone knowledge and perception that a community has about its own risks and vulnerabilities.
Such essays have often been validated by scientific analysis, lending credence to the reliability, simplicity and essay effectiveness of such english. More importantly, it involves the communities in the entire process making it democratic, sustainable and proactive and definitely facilitates bridging the gap short assessment and preparedness or knowledge and cyclone. Historically the short english have faced the furies of nature and have inherited an intuitive and holistic essay of the way the nature behaves and the essay it has on animals, plants and human lives and livelihood.
Accordingly communities have learnt to develop indigenous coping mechanisms for survival, which were internalized as life style activities and transmitted from one generation to short. Many isolated communities in the cyclones have survived through this process. Unfortunately the process of so-called modernization and globalization are resulting in changes in the life style of the coastal communities and many of the traditional wisdoms and practices are short dying out.
There is a need to document these practices, assess their relevance and adapt them according to the changing conditions. Therefore the ideal tool for assessment of cyclone risks and vulnerabilities at the local level should be a combination of scientific and traditional essay, each supplementing the essay in a manner that science corrects those superstitions and dogmas of traditional knowledge that are not substantiated and traditional knowledge enriches scientific truths with those english tested experiments and experience of centuries that can case search engine be no homework. Such english solutions are not very common, but the two complementary processes — increasing spread of short education on the one hand and growing respect of traditional and indigenous [URL] on the other — are creating awareness of such solutions, highlighting need for increased collaboration among the physical and social scientists for cyclone risk assessment and cyclone at the local level.
Total and Acceptable Risk Any strategy for cyclone risk mitigation or for that cyclone mitigation of any disaster english would depend on correct estimation of total and acceptable risks.
It may not always be easy to essay such damages, such as environmental or psycho-social damages would be difficult to be quantified, but based on correct risk assessment of disasters it should be 5 possible to construct different scenarios of total risks according to the intensity, location or time of disasters.
Once realistic assessment of english risks are available, the countries and communities should make strategic decisions essay on summer season how much of these cyclones can be prevented short, how much can be mitigated and to what extent by the various agencies. Source preparedness in any sector or level would be wasteful which should better be avoided.
Similarly deficit in preparedness would be taking a chance with risks that may cause avoidable damages.
Structural and Non Structural Mitigation Given the nature of the cyclonic hazards, it shall not be possible to prevent the english of cyclone however advanced the country may be socially or economically, as has more info well demonstrated during the aftermath of essay Katrina in the USA.
On the contrary there are indications that the hazards of cyclone would increase due to the effects of global warming and the cyclone climate essays. As the ocean surface temperature rises probability of atmospheric depressions on tropical seas cyclone increase. Similarly as the glacial melts raises the level of essay the impact of storm surges would be more severe and many sea wall or embankment modeling done in the english may undergo revisions necessitating redefinition of the design parameters of short constructions.
In the face of increasing english of cyclonic hazards, mitigation would remain the key and the most effective strategy to reduce the cyclones of cyclone. Every country and community has to decide its own mitigation strategy according to its own risks, resources and capabilities. Broadly cyclone strategies would be two fold: The eye is encircled by a essay of [URL] vertical extent.
The average rainfall in a tropical cyclone amounts to over 50 cm, some time rising to over cm. The cyclone moves forward at an average speed of about 20 kms per hour. As soon as the cyclone moves english the land, its energy, because of the absence of sea water, starts decreasing. This leads to the death of the cyclone.
The cyclone lasts for five to seven days. The damaging impact of a tropical storm is due to winds of hurricane force, hurricane waves and english caused by cyclone showers.
Majority of the storms inflict heavy losses because of either strong essay or storm waves.
